Sigma warns of aberration bug affecting some of its lenses on Canon DSLRs

11 Aug

Sigma has issued an advisory for five of its lenses over an error that occurs when they’re used with select Canon DSLRs.

The issue crops up when the cameras’ “Lens aberration correction” function is turned on. According to the company, having the lens aberration feature enabled on the Canon EOS 6D Mark II, EOS 9000D (77D), EOS Kiss X9 (EOS Rebel SL2), or the EOS Kiss X9i (EOS Rebel T7i) cameras will result in an error when paired with the following lenses:

  • SIGMA 30mm F1.4 DC HSM | Art
  • SIGMA 35mm F1.4 DG HSM | Art
  • SIGMA 30mm F1.4 EX DC HSM
  • SIGMA 50mm F1.4 EX DG HSM
  • SIGMA 85mm F1.4 EX DG HSM

Affected users are advised to keep the lens aberration function disabled until a fix is released.

Some Annoying Things About Photography and Cameras

26 May

Photography gave me a creative outlet in life, and I owe so much to it. It’s my form of escape and a way to relax. It pushes me to explore new places and it gets me out the door. I love it dearly.

That being said, there’s a lot about photography that annoys the heck out me, and here’s a list of everything I can’t stand. As a side note, I hope you don’t mind that I illustrate this article with some zen photography instead of pictures of the things that annoy me. That would just get my heart rate up too high.

Disclaimer: This article is meant to be tongue-in-cheek and have some fun. Don’t take it at all seriously, please!

Everything that annoys me about photography and cameras


Have you seen a Nikon camera these days?? Most people will never need half of those buttons in their lifetime. Can’t they invent a camera that only needs a few buttons? Where is Apple when you need them?

But seriously, I wish more camera companies put extra time into thinking about ergonomics, design, and making everyday use more pleasant rather than trying to pack each camera with new unneeded features just to lure people into an upgrade.

Everything that annoys me about photography and cameras

Lens dust

Last time I changed lenses, I was literally in a vacuum chamber and still a piece of dust got stuck smack in the middle of the sensor. And is there anyone who can clean it easily near me? Nope, because Nikon stopped making repair parts available in order to shut down third party repair companies. So not only do I have to send my Canon camera to the factory for small repairs because my local shops couldn’t stay in business without the Nikon business, but I can’t even find someone locally to quickly clean my sensor.

Yes, I know I can do it myself, but I’d rather have someone trained so that I don’t screw something up.

Everything that annoys me about photography and cameras


Remember that time when you thought you needed all these expensive filters to be a good photographer? While you do need a few filters, everyone goes overboard at some point and now has a filter graveyard drawer.

Everything that annoys me about photography and cameras


We don’t need more megapixels Sony! Our computers and external hard drives can barely keep up. Instead, give us better ergonomics, better ISO, faster focusing, and better dynamic range. Which brings me to the next point.

Everything that annoys me about photography and cameras

Small cameras with big lenses

What’s the point in a tiny mirrorless camera with a massive 20-pound lens? Is it impossible to make that 24-70mm lens that everyone uses just a little bit smaller? Please take the money from the megapixel blitzkrieg department and put it into the making lenses smaller department.

Everything that annoys me about photography and cameras


Why are all $ 300 tripods designed to fail after a year of use? I can’t imagine how much money the Planned Obsolescence Manager at Crap Tripod Inc. makes. We all learn this the hard way. We suffer until we get fed up and spend way too much money on a Gitzo that lasts us the rest of our lives and makes us really happy.

Everything that annoys me about photography and cameras

People walking in the way of your shot to get a closer shot

You’re pretending you don’t see me. I’ve been here for an hour. I’m a peaceful man, but I will strangle you with my remote shutter cord and break this tripod over your skull (not really, I’m just kidding!). Oh wait, it’s a Gitzo. This Gitzo will break your skull and then continue to work perfectly fine.

Everything that annoys me about photography and cameras

Neck pain

Please don’t carry your tripod over your neck. Use a backpack sometimes instead of a shoulder bag. Pick one lens before you go out the door instead of five. Stretch. Your body will thank you in 20 years when you’re not walking around like the Hunchback of Notre Dame.

Everything that annoys me about photography and cameras

Taking an iPhone photo of some sweaty person at a party with overhead lighting and them thinking it’s going to be amazing because I’m a photographer

I’m not Saint Theresa – I can’t perform miracles. Now stop trying to look like a duck.

Everything that annoys me about photography and cameras

People saying, “Isn’t everyone a photographer these days?”

You know, photography is a way for all types of people in all walks of life to find a creative outlet, and there’s a vibrant community of so many fun and interesting people that are drawn to it. But whether you meant it or not, that statement has a demeaning and devaluing undercurrent to it. All of us are completely different as photographers, just as anyone with a pen will write in a completely different way. Just because this amazing community is growing, does not mean that photography should be devalued.

Everything that annoys me about photography and cameras

When we’re traveling and I can’t skip out on all the fun stuff to take photos

You mean I have to go to a nice dinner at a fun looking place on the water with someone that I love dearly? What the heck – I want to go walk down this dirty alleyway for the next hour to take some moody photographs!

Everything that annoys me about photography and cameras

Canon warns of defective focusing in some EF 24-105mm F4L IS II lenses

19 May

Canon has issued a service notice for a collection of lenses with specific serial numbers that need to be checked for faulty focusing systems. The lens affected is the EF 24-105mm F4L IS II USM standard zoom, but users are advised that only particular production batches have the problem.

Canon says that some units with serial numbers beginning with 48, 49, 50 or 51 suffer from poor focusing when used with an AF point close to the edges of the host camera’s focusing array. The fault is only apparent when the lens is used at wide-angle focal lengths.

All defective lenses will be taken back for testing and repair at no cost to the owner, the company says. The Canon website carries a service section that allows owners of the lens to type in the serial number of their lens to check whether it will need to be returned.
For more information see the Canon USA, Europe or Asia service pages, or those for your local area.

Leica offers free fix for faulty AF in some S lenses

08 Apr

Leica has finally announced that it has found a reliable replacement for the defective focus drive units in some of the S lenses from its medium-format system. The faulty units created complete AF failure in affected lenses and it has taken the company some time to find a permanent solution.

In what Leica describes as an act of ‘goodwill’ users with lenses that have already stopped working can have the AF drive units replaced for free, as can anyone whose unit fails up to five years from the date of purchase. Those whose drive units are still functioning can also have theirs replaced but for a charge of around $ 400 according to Red Dot Forum. That fee includes an extra year of product warranty for all lenses, no matter how old.

The free replacement service has been on offer since the end of 2015 but until now the company was replacing broken units with the same kind of drive motor. This new announcement relates to a new drive unit that is said to be more reliable.

Press release

Official Release from Leica AG

In some cases, a defect may appear in the autofocus drive unit of Leica S-Lenses. Under certain unfavorable conditions, this may lead to a complete loss of the autofocus function.

We are pleased to inform you that we have successfully completed the development and stringent quality assurance testing of a new generation of autofocus drive units under practical conditions.

Leica Camera AG is prepared to offer a free replacement of the autofocus drive unit of S-Lenses affected by this problem within the terms of a goodwill arrangement.

In light of this, we would like to remind our customers that we can offer free replacement of the autofocus drive unit only for S-Lenses affected by this concrete defect. The goodwill arrangement will remain valid for a period of five years from the date of purchase of the respective S-Lens.

Preventive replacement of the autofocus drive unit (including a warranty extension of 12 months) may be requested at your own expense.

Should the defect described above occur in one of your S-Lenses, we recommend that you send it directly to Leica’s Customer Care or the authorized Customer Care department of your country’s Leica subsidiary.

Contact: or Telephone: +49 (0)6441 2080 189.

We consider it our obligation to provide only technically faultless products. We therefore particularly regret that the functions of one of your S-Lenses could have been be impaired by this defect. We hope that the goodwill arrangement we are offering will allow us to resolve this issue as soon as possible and rebuild and maintain the trust you have always placed in the Leica brand and its products.

Just Pull Some Strings: 8 Easy Transforming Furniture Designs for Lazy People

21 Mar

[ By SA Rogers in Design & Furniture & Decor. ]

gesture controlled transforming furniture

When you’re lazy, even the most intuitive transforming furniture isn’t easy enough to operate unless it’s on the same level as clapping your lights on and off. Luckily for those of us who fall into this category, some furniture makers are creating multifunctional designs for small spaces that work their magic at the push of a button, the pull of a string, a flick of the wrist or even a mere gesture.

Retractible Ollie Chair by RockPaperRobot

ollie chair flat pack

ollie chair

ollie chair

You really have to watch the video of how this chair works to fully appreciate its brilliant simplicity. It starts as an entirely flat panel of slatted teak wood with a slight curve at the top. Pick it up, pull a string and the whole thing unfurls into a seat in a single fluid motion that’s very satisfying to watch, and it works the same way in reverse. The slats are affixed to a textile canvas to make the seating flexible, and the rest takes folding inspiration from origami.

A-Board Flat-Pack Shelf


a-board 2

This bookshelf starts as a flat piece of laser-cut plywood. Yang the orange ribbon on the back, and it will pull the shelves down perpendicular to the face so you can rest the whole thing against a wall and use it as a bookshelf. Designer Tomas Schön used a laser-cutting technique to bend the wood instead of hinges, and there’s no other hardware or even glue involved.

MIT Media Lab CityHome

MIT cityhome 3

Still not easy enough for you? How about commanding your bed to slide out with a gesture of your hands? MIT’s robotic ‘home in a box’ can pack a full, spacious-feeling apartment into 200 square feet of space, including a bed, workspace, dining table for dix, storage and a mini kitchen. The box uses built-in sensors, motors, LED lights and low-friction rollers to respond to your voice commands or gestures.

Ori Robotic Home Controlled via Smartphone App

There are all sorts of complex transforming furniture systems designed to fit maximum function into small spaces, but how many of them are operated through a smartphone app? The Ori system (taking its name from the prefix of ‘origami’) runs on robotic technology, featuring an on-device user interface as well as an app for your handheld device so you can press a button to initiate various configurations, like the bed sliding out, the table folding down or the entire unit moving to tuck itself against a wall to open up the floor area.

This photo of some strawberries with no red pixels is the new ‘the dress’

02 Mar

UCLA neuroscientist Matt Lieberman posted the ‘no red pixels’ image on the left. It’s developed from an original by Experimental Psychologist Akiyoshi Kitaoka (right) that, despite appearances, does have some very slightly red-tinged pixels in it.

Remember internet kerfuffle that was ‘the dress’ ? Well, there’s another optical illusion that’s puzzling the internet right now. Behold: the red strawberries that aren’t really red. Or more specifically, the image of the strawberries contains no ‘red pixels.’

The important distinction to make here is that there is red information in the image but, despite what your eyes might be telling you, red is not the highest value for any individual pixel in the image. Hence, no ‘red pixel’ in the image.

As was the case with ‘the dress,’ it all relates to a concept called color constancy, which relates to the human brain’s ability to perceive objects as the same color under different lighting. Which should immediately bring to mind a familiar photographic concept: white balance. Although there’s a significant cyan cast to the whole image, your brain is able to correct for it without you having to consciously identify a neutral part of the image (as you’d need to in processing software).

This got us thinking: without any understanding of what strawberries look like, how well would a camera’s auto white balance cope with the significant color cast in this image?

Here’s what a Nikon D7200’s auto white balance algorithms made of the image (defocused slightly, to avoid moiré from the monitor’s pixels)

The answer? Pretty well, actually. We don’t know whether it’s been able to detect the overall cyan cast or has assumed that the brightest point in the image is probably neutral, but it’s done a good job.

We have Experimental Psychologist Akiyoshi Kitaoka to thank for turning this puzzle loose on the world, and neuroscientist Matt Lieberman for turning it viral. Curiously, the first image contains a few red-dominated pixels (which Lieberman’s edited version doesn’t), yet appears more grey than Lieberman’s version.

CP+ 2017 – Sigma interview: ‘We’ve learned that some customers require exceptional lens performance’

27 Feb
Kazuto Yamaki, CEO of Sigma Corporation, pictured at CP+ 2017, with Sigma’s new 14mm F1.8.

Sigma released four lenses at this year’s CP+ show in Yokohama – the 14mm F1.8 DG HSM Art, 24-70mm F2.8 DG OS HSM Art, 135mm F1.8 DG HSM Art and 100-400mm F5-6.3 DG OS HSM. We’re at the show, where we made time to sit down with Kazuto Yamaki, CEO of Sigma, to find our more about the new lenses. 

You’ve told me previously that you really want Sigma to make more wideangle lenses. Do you think you’re achieving that goal with the 12-24mm and new 14mm?

Yes, but I’m still not satisfied. I think we need to make more wide-angle lenses. A fast 14mm was one of the lenses that our customers were asking for. Most existing 14mm lenses are F2.8, so F1.8 was a challenge.

The new Sigma 14mm F1.8 is the fastest lens of its kind, and according to Sigma, should outperform competitive, slower designs from other manufacturers.

What have you learned, from making the Art series?

We’ve learned that some customers require exceptional lens performance. We believe that our mission is to make products that other manufacturers don’t have. If we just released similarly-specified lenses to existing models, we wouldn’t be contributing to the industry, or benefiting customers. So our Art series is meant to provide the best performance.

They’re bulky and heavy, it’s true, but our customers like them because of the performance. That’s what we learned.

Hands-on with Sigma MC-11 (CP+ 2016)

You now make a mount adapter for Sony E-mount, but are you planning native support for the Sony E-mount in the future?

Yes, that’s our plan. Our plan is to develop full-frame lenses for Sony E mount, and in the future we will have more E mount lenses. But it takes time. Normally it takes about two years to develop one lens, sometimes three. So even if I start the process now, the lens might come out in two years time.

Sigma’s new Art-series lenses have a degree of weather-sealing – why now?

It’s based on customer demand. Some of our customers said that rain and snow sometimes got into the lens mount, so they wanted sealing. And the other reason is that it’s becoming a trend. Other manufacturers are offering sealed mounts.

Does that make the design process more complex?

No, not really. The only seal is around the lens mount. It’s not a perfect weather-proofing like our Sports series. The 150-600mm for instance has sealing everywhere, on the focus ring and zoom ring.

Of the lenses in the Global Vision line, which were the most complex to bring to market?

Our 12-24mm zoom. Because that lenses uses a very large aspherical element, and at the time, no other company was producing an element of this kind, and there were no machines capable of producing it. So we designed a custom machine to make that element. But as a result of developing that technology, we were able to create this new 14mm F1.8.

The Sigma 12-24mm ultra-wide zoom is a complex design, containing a very large aspherical (front) element.

The Global Vision line is almost five years old. What are you most proud of?

Firstly, I’m still not satisfied. We need to do more. But these days, I’m pretty happy that people regard Sigma as a high-quality company. In the past, some people regarded Sigma as just another third-party lens manufacturer, and maybe even as a cheap, low-quality lens supplier. But people’s perception has been changing, gradually, and I’m very happy about that.

One of the things that professional Canon and Nikon photographers rely on is the support networks for service, like CPS and NPS. Is a professional service support system something that Sigma is interested in creating?

I think we’ll have to. In Japan we’ve already started a pro support project, and I hope we can create a global professional support system very soon.

In the past you’ve expressed concern that you don’t want Sigma to grow too much, too quickly, because this might threaten some the magic of being a small company. Is this something that you’re still worried about?

Growing too fast is not good. We need to grow, but we should grow gradually. We need to develop our capability to produce higher-quality products. That’s the priority. Then turnover, and sales, and profit will follow. We do not prioritize making the company bigger. We focus on product quality, and technology.

Over the past five years, we’ve actually been making fewer lenses, because we decreased the number of cheaper lenses we were producing. But we’ve expanded our manufacturing capacity, because the higher-end lenses use more glass. Cheaper lenses might use 10-15 elements, but these higher quality lenses use 15-20, sometimes even more elements. So more capacity is needed to make a single lens. We’ve actually invested massively in the past five years.

Sigma and Fujifilm have recently introduced lineups of cine lenses. How much growth do you see in this segment?

We don’t know. Even before I decided to get into the cine lens market, I tried to collect market data, but there’s no data out there. It’s not available. It’s only anecdotal. But we guessed that this segment will grow in the future.

Video has lower resolution demands than stills, but we’ve been designing lenses for 36+ megapixel sensors for several years. That is equivalent to 8K, in video terms. A lot of traditional cine lenses aren’t that high resolution. Our lenses might be more affordable, but they’re top quality.

The Sigma Cine lens range includes a geared version of the company’s 18-35mm F1.8, now known as the 18-35mm T2. The lens covers the Super 35 format and requires a roughly 350 degree rotation to zoom from 18-35mm, allowing very precise control.

Do you have a market share target for your cine lenses?

No, we’re waiting to see how the market develops. We can dream, but it’s not the same thing!

Editors’ note:

We always enjoy speaking to Mr Yamaki, partly because on the occasions when we get the opportunity to do so, it’s usually because he’s just unveiled something really interesting. Mostly though, we enjoy speaking to Sigma’s CEO because he’s a nice guy. Open, honest, and candid about Sigma’s plans and ambitions, Mr Yamaki is well-liked in the photography industry, even by his competitors.

Speaking of competitors, I get the feeling that Mr Yamaki was compelled to deliver the new 14mm F1.8 partly out of a general disappointment with the available options for photographers. Sigma has a strong history of innovating in the wide and ultra-wide market, and the new 14mm, alongside the previously-released 12-24mm certainly look like a confident statement of intent. If the 14mm is as good as Mr Yamaki claims (and we are rarely disappointed by the optical performance of Sigma’s Art series) it looks set to be a reference lens for landscape, architectural and astrophotographers. We’re hoping to be able to post a gallery of samples very soon – watch this space.

Also interesting, is another statement of intent – Sigma’s move into affordable cine lenses. While the company is not competing (yet) with the Arris of this world, or with Canon’s Cinema EOS optics, Sigma (like Fujifilm) sees an opportunity to cater to a newer generation of videographers who are working with mirrorless systems. Optically, Sigma’s cine lenses should be top notch, although being based on existing stills lens designs, we’re told that some qualities, such as focus breathing, might cause issues for professional broadcast and film cinematographers. There is a reason, after all, that high-end professional cine lenses can cost tens of thousands of dollars.

So what next for Sigma? We wouldn’t be surprised if Mr Yamaki is working on more wideangle lenses, and following the new 24-70mm F2.8, it seems likely that the company will refresh its 70-200mm F2.8 in the near future, too. More Sony E-mount optics are also on the way, we’re told, which will be welcome news to Sony a7-series users.

Some Options for Backing Up Your Photos Online

27 Jan

Backing up your data is an essential part of your photography workflow. While many photographers still advocate for using physical external hard drives, there are also many online services where you can store your images. In this article, I will go over the pros and cons of several popular sites to backup your photos online. Please note that these photo solutions are constantly changing their features, so always check with them directly to verify any details.

Photo backups versus photo sharing sites

Some Options for Backing Up Your Photos Online

It’s important to note the differences between a designated photo backup services and photo sharing websites. Traditional photo backup services such as Backblaze and CrashPlan focus purely on backing up data and can be set to backup an entire computer or hard drive. This is good in the sense that you can have everything you’ve ever created on your computer saved to the cloud. However, these backups end up being extremely large files and they take extra time to retrieve. So if you need to constantly and quickly access your backed up photo data, it may not be wise to rely solely on these types of providers.

Photo sharing sites, on the other hand, are not meant to be comprehensive backups of your entire computer. Many of these sites impose limits on the types and sizes of files that can be uploaded. Thus, photo sharing websites are best used to upload, store, and share edited photos.

How I backup my photos

My advice is to have a backup for your backup. As a professional photographer who shoots primarily in RAW, I have terabytes of data to store, but I don’t generally need frequent access to those original files. I opt for CrashPlan to do automatic backups of my RAW images, in addition to storing them on external hard drives.

My photography business is such that I constantly need to dig up old high-resolution photos to present to clients, and CrashPlan doesn’t give me easy, immediate access to those files. So I save edited, high-resolution copies of every photo I take and upload them to SmugMug. This way, I have quick access to the photos and can easily prepare an online gallery to share and sell images to clients. I also have Google Photos set to do automatic online photo backups anytime I save a new JPG image to my computer. In the end, I have four ways of backing up my photos.

Backup Services

These are comprehensive backup and cloud storage solutions meant to hold large amounts of data. Set them to automatically backup your entire computer or hard drive, and practically any file type or size will be accommodated. On the plus side, these backup solutions are pretty affordable for what they offer. However, it can take a long time to backup huge files, and file restoration can also take a bit of time.


One of the most popular backup solutions, Backblaze can automatically backup an unlimited amount of data from a single computer (note; it will connect and backup external drives as well). There’s no restriction on file type or size, and there’s only one pricing plan. It costs $ 5.00 per month or $ 50 USD per year for a Backblaze account. You can even pre-pay $ 95 for a 2-year plan. It’s an affordable and reliable solution for making sure everything on your computer is backed up.

Virtually the same as Backblaze, CrashPlan also offers automatic computer backups. The main difference is that CrashPlan offers several different subscription plans. Included in the free plan is an automatic backup to a local hard drive or another computer. If you want to backup your data to CrashPlan’s cloud, the cost is $ 5 per month to backup one device for unlimited cloud storage and mobile file access. To add an extra device (as many as 10), the Family Plan is available for $ 12.95 per month.

Amazon Cloud Drive

At $ 11.99 a year for unlimited photo storage (or free for Amazon Prime members), Amazon offers competitive cloud storage solutions, but at some expenses. The main downside to Amazon Cloud at the moment is its lack of features when compared to other more established solutions. For example, a desktop client must be used to upload files larger than 2GB, there are no automatic backup features, and stored files are not automatically updated. Given these underdeveloped features, Amazon Cloud Drive at this moment seems more like an off-site hard drive rather than a true backup solution.


Microsoft OneDrive

Formerly known as SkyDrive, OneDrive is Microsoft’s cloud storage solution that works with Windows, Mac, iOS, and Android devices (but still no Linux). Base plans include a generous 15GB of free storage. Paid plans start at $ 1.99 a month for an extra 100 GB, or $ 6.99 for 1TB of space. The main downsides are a slow upload and download speed, a 10GB size limit per file, and the need to have a Microsoft, Outlook, or Xbox Live account in order to access OneDrive. This may be a hurdle for those who don’t use any Microsoft or Windows products.


Google Photos

The photo storage solution offered by Google takes a slightly different approach than that of Dropbox or Flickr. Google Photos offers unlimited backup of a wide variety of file formats (including RAW images). You can also set automatic backups to occur whenever a new photo is taken on your mobile device or saved to your computer. However, all photos and videos must be under 16 megapixels or 1080p HD video.

If you upload larger files under the unlimited plan, your files will be compressed to fit these maximum size requirements. The only way to upload original, full resolution images is to opt for a plan with limited storage. In a way, this makes sense. You pay for more storage space if you need it.


Photo Sharing and Image Hosting Websites

These websites were not originally meant to be comprehensive backup solutions. However, many photographers have begun using them as such. Most of these websites have limitations when it comes to data storage or file types that you can upload. Thus, they may not be the best all-around backup solution for your photos, depending on your needs.


One of the most popular tools to backup photos online is Dropbox. It exists in the form of a mobile app, website, and desktop app and allows you to store all types of media including photos, documents, videos, and other files. Anything you add to Dropbox can be immediately accessed anywhere when you log in via the corresponding website or app.

Using the free version gives you 2MB of storage space, but you can purchase additional space. Dropbox made an attempt at pushing an automatic photo backup feature in the form of Dropbox Carousel. However, this app along with Dropbox’s email app Mailbox shut down in early 2016. Thus, it’s questionable if they will make future investments into further feature development.



Yahoo’s venerable photo solution, Flickr, has withstood the test of time and continues to be popular among amateur and professional photographers. Even with a free account, you get 1TB of photo storage space. However, you cannot get more than 1TB of space, even with a paid Flickr Pro account. Instead, the paid account just removes ads and gives you access to your account stats. While Flickr isn’t the best for sharing photos with clients, it does give you the option to license and sell your photos.

The main downside to Flickr has to do with file size limits. Uploaded photos cannot be more than 200MB and videos must be 1GB or less in size. Additionally, RAW images cannot be uploaded.


SmugMug, Zenfolio, and Photo Shelter

These three paid photo-sharing websites are popular for presenting and selling photos to clients:

  1. SmugMug
  2. Zenfolio
  3. PhotoShelter

However, the push for offering unlimited photo storage has elevated these sites into becoming viable ways for photographers to backup images. All three sites also offer components that help you build your photography website. SmugMug and Zenfolio are among the most affordable, while PhotoShelter is more expensive.

In Conclusion

So which photo backup solution is best for you? It truly depends on what media you are looking to backup, how often you will access it, and your budget. Whichever solution you choose, remember to always have a backup for your backup. Also, please remember that these services are constantly offering new promotions and features. The information in this article may change, so always check directly with the provider to verify details.
