PSA: Apple warns that high-powered motorcycles can damage autofocus, image stabilization in iPhones

13 Sep

Apple has published a new support document on its website warning users that cameras on their iPhone devices can be damaged when attached to high-powered motorcycles due to the ‘high amplitude vibrations’ of their engines.

In the document, Apple specifically points to the optical image stabilization (OIS) and closed-loop autofocus (AF) technologies inside its latest iPhone device and notes both of these are susceptible to performance degradation over time when exposed to the ‘extended high-amplitude vibrations,’ such as those put through the device when it’s attached, via a mount, to a motorcycle. Specifically, Apple notes the OIS systems inside the iPhone 6 Plus and later and the AF systems in the iPhone XS and later are the modules affected by these issues.

‘High-power or high-volume motorcycle engines generate intense high-amplitude vibrations, which are transmitted through the chassis and handlebars,’ says Apple. ‘It is not recommended to attach your iPhone to motorcycles with high-power or high-volume engines due to the amplitude of the vibration in certain frequency ranges that they generate.’

Even smaller motorized vehicles, ‘such as mopeds and scooters,’ can lead to problems, despite ‘comparatively lower-amplitude vibrations,’ according to Apple. To lessen the risk of damage on these devices, Apple suggests using a vibration dampening mount and ‘avoid regular use for prolonged periods.’

Canon Japan warns R5, R6 and accessories could ship later than expected due to demand

14 Jul

Canon Japan has warned consumers that pre-orders for its R5 and R6 mirrorless cameras — as well as some accessories — might ship later than expected due to pre-orders ‘exceed[ing] expectations.

The machine-translated statement reads:

Information About Product Supply Status

We have received orders for the following products announced on July 9, 2020 that exceeded expectations, and it may take some time before the products are delivered.

[Applicable Products] EOS R5 / EOS R6 / Battery Grip BG-R10 / Extender RF 1.4x / Extender RF 2x

We would like to thank you for all the orders we have received, and we apologize for any inconvenience caused to our customers waiting for the release. Thank you kindly look forward for your understanding.

This isn’t the first time we’ve seen this kind of announcement following the launch of new and exciting camera gear: Nikon, Panasonic, Sony and others have done it in the past.

While there’s reasonable suspicion in these instances whether it’s purely a PR move to further drum up interest or a genuine warning that units might ship later than expected, it’s worth noting Canon specifically suggests shipments could be delayed. So, it’s worth keeping tabs on your order progress if you’ve pre-ordered one of the affected cameras or accessories.

Viltrox warns some of its X-mount prime lenses can cause damage to X-Pro3 camera bodies

13 May

Lens manufacturer Viltrox has issued a statement warning customers that a number of its X-mount lenses can damage Fujifilm X-Pro3 camera bodies.

The statement, seen below, notes that ‘it would be better not [to] use [the] Viltrox 23mm, 33mm or 85mm X-mount lenses’ with Fujifilm X-Pro3 camera systems, as it can damage the camera ‘due to the structural conflict [wherein] they will scratch a little bit against each other.

This information is backed up by reports on this DPReview forum post from Pete Richardson that notes his Viltrox 85mm lens rubs up against the lens release button on the X-Pro3 camera body, causing ‘the slightest mark on the edge of the collar surrounding the release button.’ The reason this only affects X-Pro3 camera bodies is that the lens release button sticks out ever-so-slightly further than that on the X-Pro2, as illustrated in this screenshot from CameraSize.com by DPReview reader DarnGoodPhotos:

Note how the lens release button on the X-Pro3 sticks out marginally further than on the X-Pro2.

If that is the case, the damage would be mostly cosmetic, but it’s probably best to avoid using the lenses with the camera unless you don’t mind scratching up either item.

Fujifilm warns its customers to avoid sending undeveloped film through new airport scanners

19 Feb

Fujifilm has joined Kodak Alaris in warning its customers to avoid sending film through new scanners being deployed by the TSA in many airports throughout the United States. The advisory is brief and simply states, ‘Those machines may [be] more damaging to unprocessed film and Instax film than previous generations of scanners.’

The solution is simple: photographers are encouraged to pack their film products in a carry-on bag and to request a hand inspection of the items.

This is similar to the warning Kodak Alaris published in late January; the company received clarification from the TSA, which said that its screeners are trained to inspect film by hand. As well, the TSA has put warning signs near X-ray machines that may damage undeveloped film. The film should be packed in a clear plastic bag and removed from the carry-on luggage at the security checkpoint.

Gary Fong warns of counterfeit Lightsphere flash diffusers

11 Feb

Photographer Gary Fong, the creator of the Gary Fong Lightsphere, has published a video that warns about counterfeit Lightsphere products being sold on Amazon. Fong showcases the authentic product alongside the counterfeit product, highlighting differences that will help consumers spot the fake, as well as issues with the counterfeit product’s design.

The Lightsphere is a collapsible flash diffuser that is made from clear material sporting horizontal rings. The counterfeit version sold on Amazon, Fong points out in his video, is made from flimsy material that doesn’t hold its shape. As well, the counterfeit product is made from material dyed white rather than left clear, which impacts the diffuser’s performance.

As the video explains, the differences between the real diffusers and counterfeit diffusers are nearly indistinguishable.

In addition, the dome doesn’t stay fixed in the counterfeit product and instead easily falls out. The entire product, including the package, shows multiple signs of being fake, including poor print quality on the diffuser’s strap, a shiny rather than a matte box, a product insert that has poor print quality and poor image quality on the package’s label.

Fong shows images to prove that not only did Amazon sell this product, but in fact presented it as its ‘choice’ to buyers and shipped it directly from its own warehouse. In order to avoid a fake product, consumers can purchase the Lightsphere directly through Gary Fong’s website, though it should be noted that not all Lightspheres sold by Amazon are fake.

Kodak Alaris warns the TSA’s new airport CT scanners can damage undeveloped film

29 Jan

Kodak Alaris has alerted its customers to the risks of CT scanners being used by the TSA to scan carry-on luggage in a number of airports throughout the United States. According to the company, it tested the effects of these scanners on film products to determine just how risky they are. The results, according to a long Facebook post from Kodak Alaris, were ‘not good.’

In March 2019, the TSA announced a $ 96.8 million contract that had been awarded to Smiths Detection for 300 CT scanning systems that will be installed in 145 U.S. airports to screen carry-on bags. Some of these CT scanning systems are now in use at select airports and others will go live over the coming year.

‘To better assess the risk to film from the new carry on scanners we brought a small quantity of Portra 400/135 to John F Kennedy Airport,’ Kodak Alaris explains on Facebook. The film was put through these scanning systems one to 10 times and then was later evaluated by Eastman Kodak Research experts.

Kodak describes the results as ‘not good,’ saying:

Just 1 scan shows significant film fogging, leading to smoky blacks and loss of shadow detail. This will be more significant for higher speed films. Although it’s possible that a roll of 100 speed film would show less degradation, we strongly recommend against putting any unexposed or exposed but unprocessed film through a CT Scanner.

In order to avoid this, Kodak tells photographers to keep their film products in a carry-on bag and to request that TSA agents hand-check the film rather than sending it through the CT scanner. The TSA confirmed to Kodak that its agents are trained in hand-checking movie film, roll film and single-use film cameras.

The TSA warned Kodak that ‘a limited number of [carry-on] screening checkpoints’ feature X-ray equipment that may damage film. In these cases, the airports have put up warning signs at the checkpoints to warn passengers who may have undeveloped film in their bags. The majority of X-ray screening equipment used for checked baggage rather than carry-on baggage will damage undeveloped film as well, according to the TSA.

Kodak says it is developing ‘warning stickers’ that photographers will be able to print out at home and put on plastic bags containing their film products when traveling.

Security firm warns Android camera vulnerability lets hackers spy on phone owners

21 Nov

Security analyst firm Checkmarx has detailed the discovery of an Android security issue that enables hackers to access a smartphone’s camera app, existing videos and images, audio from the microphone and location information pulled from EXIF data. Though the issue has been fixed on Google and Samsung phones, it remains in many camera apps from other vendors

The security researchers first analyzed the Google Camera app included on the Pixel smartphones. Upon discovering the security vulnerability, which involves ‘manipulating specific actions and intents,’ they found the same issue could be exploited in the Samsung Camera app included in its various smartphone models.

The vulnerability is extensive, according to the researchers. Hackers can access the camera app, use it to capture videos and photos even if the display is turned off or a call is in progress and access content saved to the phone. In addition to accessing the images, hackers could pull the location information from image metadata and use that to locate the handset’s owner.

The exploit introduces a number of privacy issues for users; attackers could use the video recording functionality to record a phone call, for example, and could retrieve sensitive images from the user’s phone for blackmail purposes.

According to Checkmarx, Google confirmed that the issue isn’t limited to the Pixel phones and that it is working with its Android partners ‘to coordinate disclosure.’ Both Google and Samsung released fixes for the security issue in their respective camera apps before Checkmarx published its report. It’s unclear how many phones from other vendors may still be vulnerable to the exploit, however.

US government warns of potential spying by Chinese drone companies

23 May

On Monday, the U.S. Department of Homeland Security (USDHS) sent out an alert that was first obtained by CNN. It states that drones manufactured in China are a ‘potential risk to an organization’s information.’ The products ‘contain components that can compromise your data and share your information on a server accessed beyond the company itself.’

‘The United States government has strong concerns about any technology product that takes American data into the territory of an authoritarian state that permits its intelligence services to have unfettered access to that data or otherwise abuses that access,’ the alert continues.

‘Those concerns apply with equal force to certain Chinese-made (unmanned aircraft systems)-connected devices capable of collecting and transferring potentially revealing data about their operations and the individuals and entities operating them, as China imposes unusually stringent obligations on its citizens to support national intelligence activities,’ the alert adds.

While the report doesn’t name a specific company, Shenzen-based DJI, which dominates the U.S. and Canadian drone markets with close to an 80% share, according to a market sector report from Skylogic Research, is of utmost interest.

While the report doesn’t name a specific company, Shenzen-based DJI, which dominates the U.S. and Canadian drone markets with close to an 80% share, according to a market sector report from Skylogic Research, is of utmost interest. The manufacturer’s drones were recently banned in the US Army several years back, despite no clear evidence of spying or data transfer from the aircraft being presented.

Still, concerns about hacking or the siphoning of data remain at the forefront. The USDHS alert follows an executive order, signed by President Donald Trump, prohibiting U.S. companies from using any telecommunications equipment from Chinese company Huawei. An escalating trade war between the two countries doesn’t help matters and also raises suspicion on the timing of this latest USDHS alert on drones.

The United States leads the world in the number of drone platforms being developed. China comes in a close second place. If the trade war continues to escalate, many upstarts and manufacturers in the U.S. are going to face unexpected challenges with their supply chain if they built their platforms around any Chinese components, as sUAS News points out.

DJI responded to the USDHS’ alert, the full statement is below:

‘At DJI, safety is at the core of everything we do, and the security of our technology has been independently verified by the U.S. government and leading U.S. businesses. DJI is leading the industry on this topic and our technology platform has enabled businesses and government agencies to establish best practices for managing their drone data. We give all customers full and complete control over how their data is collected, stored, and transmitted. For government and critical infrastructure customers that require additional assurances, we provide drones that do not transfer data to DJI or via the internet, and our customers can enable all the precautions DHS recommends. Every day, American businesses, first responders, and U.S. government agencies trust DJI drones to help save lives, promote worker safety, and support vital operations, and we take that responsibility very seriously. We are committed to continuously working with our customers and industry and government stakeholders to ensure our technology adheres to all of their requirements.’

Award-winning film shot through Hasselblad 500CM warns of photo obsession dangers

13 Nov

I think there may be more than a few of us who have been told that we spend too long looking through a viewfinder instead of experiencing life first hand. And there will be plenty of us who know that sometimes we don’t get to experience an event because we are constantly looking for the best angle and thinking photography rather than feeling the moment as everyone else is.

Filmmaker Casey Cavanaugh has made a really cool film on the subject, and has created a wooden rig that allowed him to mount his Sony a7S above the viewfinder of a Hasselblad 500CM so he could record the movie through the viewfinder of the medium format film camera. I won’t spoil the story for you, but it doesn’t end well for the Hasselblad! Cavanaugh also shared the main actress in the film, Corrina VanHamlin, tragically passed away after it was made.

Link in bio || We all had a really amazing time making this short film for the Capital City Film Festival. Watching it now is a little more difficult for me as well as anyone who might have known the amazing lead actress, Corrina VanHamlin. She tragically passed away this year and her performance in this film is but a glimpse into the wonderful and talented person she was. I’m extremely grateful that we were able to make this piece of art together.
