Canon Korea promo video confirms the RF 70-200mm F2.8 lens won’t have internal zoom

10 Oct

A new video from Canon Korea gives us a closer look at Canon’s upcoming RF L F2.8 trinity and confirms what we’ve suspected from the get-go with the upcoming RF 70-200mm F2.8—it won’t be an internal zoom.

The 72-second video shows off sample images and specifications from each of the three lenses Canon showed off earlier this year: the RF 15-35mm F2.8 L IS USM, RF 24-70mm F2.8 L IS USM and RF 70-200mm F2.8 L IS USM.

As expected from the first time we saw the ridiculously compact 70-200mm F2.8 L IS USM, the lens will have an extending section for when shooting at longer focal lengths, as seen in the animated GIF above. This video marks the first time we’ve seen the extending section in action and as seen in the video, the zoom ring will have a rather short throw when going from 70mm out to 200mm.

Pricing and availability for these three lenses are still up in the air, but we expect to find out before the end of the year based on Canon’s own lens roadmaps.

The 16-55mm F2.8 provides Sony APS-C shooters with a useful 24-82.5mm equivalent range and a bright, constant aperture. We put it on a6500 to see if Sony’s claims of excellent edge-to-edge sharpness hold up – take a look for yourself.

Laowa delays the release of its 4mm F2.8 Fisheye lens for MFT camera systems

11 Sep

In a post on Sightron Japan’s website, it has announced that the Laowa 4mm F2.8 Fisheye lens for Micro Four Thirds (MFT) camera systems has been postponed.

In a very brief notice (translated) on its information page, Sightron says the lens, which was set to be released this coming Friday, has been delayed. The machine-translated version of the notice reads ‘since there is a possibility that a problem individual was mixed, we decided to postpone the release.’

Based on that translation, it seems as though a number of lenses had issues, but Laowa couldn’t pinpoint down exactly what lenses were affected and are therefore going back through and testing the units that have already been produced.

Sightron, says ‘details regarding the release date will be announced as soon as they are determined.’ It ends the post by thanking interested parties for their understanding and patronage. We’ve contacted Venus Optics for additional details and confirmation on what regions are affected by this delay. We will update this article accordingly when we hear back.

Update (September 11, 2019): This article originally mistated the relationship between Sightron Japan and the Laowa brand. It has been updated accordingly.

Hands-on with the Sony E 16-55mm F2.8 and 70-350mm F4.5-6.3

30 Aug

Meet the Sony E 16-55mm F2.8 G

It’s been a long time since Sony released new lenses for its APS-C bodies, and the new 16-55 F2.8 G is a pleasant surprise. The lens’ zoom range is equivalent to 24-82mm on a full-frame body and fills in a gap in Sony’s lineup which, up until now, has been mostly comprised of slow kit zooms. The one exception is the Sony/Zeiss 16-70mm F4, which has a more versatile range, but is a stop slower than the new 16-55.

Given its spec, it shouldn’t come as a huge surprise that the 16-55mm F2.8 is on the pricey side, with an MSRP of $ 1399 US. The lenses most similar to this one are the Canon EF-S 17-55mm F2.8 ($ 829 US, but not as wide) and Fujifilm 16-55mm F2.8 ($ 1199 US).

Meet the Sony E 16-55mm F2.8 G

The 16-55mm F2.8 G has a total of 17 elements, including two aspherical, two advanced aspherical and three ED (extra-low dispersion) lenses. It has 9 rounded aperture blades, which Sony (naturally) says produces beautiful bokeh. Sony uses a Nano AR coating to reduce ghosting and flare, and the front element has a fluorine coating to repel oil and water. Speaking of water, the 16-55 F2.8 is dust and moisture resistant.

Sony uses an ‘XD’ linear motor to drive the focusing group, which is the same type of motor found its more expensive G Master lenses. The lens can focus down to 0.33m (1.1ft), with a maximum magnification of 0.66x. The manual focus ring has a linear response, which videographers will appreciate.

Meet the Sony E 16-55mm F2.8 G

As you can see from the above photo, the 16-55mm is remarkably compact for a fast zoom, even one for crop-sensor cameras. At wide-angle, the lens is 10cm (3.9″) long and it does’t extend that much farther at full telephoto (Sony does not publish the actual length). It weighs in at 494g (1.1lbs), which is more than 100 grams lighter than the Canon EF-S 17-55mm F2.8.

Just under the ‘G’ is the focus hold button – its function can be customized on the camera. Over to the right is the AF/MF switch.

Going long: the Sony E 70-350mm F4.5-6.3 G OSS

Sony also announced a lens for the wildlife photographers out there, in the form of the 70-350mm F4.5-6.3 G OSS. The lens has an equivalent focal length of 105-525mm when mounted on an APS-C body, which is an incredibly versatile range, though its slow maximum aperture range makes this lens best suited for shooting outdoors. For those wondering if they can stretch the focal length out even further using a teleconverter, the answer is ‘no’.

The 70-350 has a total of 19 elements, which include 1 aspherical and 3 ED lenses. As with the 16-55, the 70-350 uses an XD linear motor to quietly drive the focusing group. There are 7 circular aperture blades on the 70-350.

Image stabilization is a must on lenses like these, and the 70-350 has it, though Sony doesn’t publish any estimates on how many stops of shake reduction the lens offers.

Going long: the Sony E 70-350mm F4.5-6.3 G OSS

Despite its focal length, the 70-350 is remarkably compact. When collapsed it’s 142mm (5.6″) long, and is of reasonable length even at full telephoto. It weighs in at just 625g (1.4lbs). The lens is resistant to dust and moisture.

As with the 16-55, the 70-350 has a customizable focus hold button and an AF/MF switch. There’s also a switch for turning OSS (Sony-speak for image stabilization) on and off, and a zoom lock switch that’s not visible in this photo.

The 70-350mm F4.5-6.3 G OSS will set you back $ 1000, which isn’t a bad deal considering that the FE 70-300 F4.5-5.6 G OSS lens sells for just under $ 1200.

Wrap up

After a long drought, it’s nice to see Sony releasing APS-C lenses again, especially given the rate at which they still release a6000-series bodies. While everyone likes a relatively compact superzoom lens, it’s great that Sony finally released a fast lens that can serve as a nice replacement to the slow, plasticky kit lenses that often come bundled.

You can view photos from both of these lenses in our a6100 and a6600 galleries (filter by lens to find them on the desktop version of our site). We’ll have dedicated lens galleries when the 16-55 and 70-350 are in our hands in the not-too-distant future.

In the meantime, feel free to share your thoughts about these new lenses in the comments below.

Samyang launches AF 18mm F2.8 FE lens for Sony full-frame cameras

30 Aug

Samyang has listed a new AF 18mm F2.8 FE lens as available for pre-order. The model has appeared on the Samyang website and Adorama, offering photographers an ‘ultra-compact’ lens with a 100-degree field of view (FOV) for Sony full-frame cameras. The lens weighs 145g (5.1oz), features 9 elements in 8 groups, 7 diaphragm blades, 58mm filter size, F2.8 to F22 aperture and 0.09x maximum magnification.

The Samyang AF 18mm F2.8 FE lens features a stepless motor and is constructed from a ‘glass-strengthened composite material,’ according to the company, which offers a combination of durability and reduced weight. The lens’ glass is ‘ultra multicoated’ for what Samyang describes as high sharpness, contrast and clarity with minimal distortion.

Below is a sample gallery of images provided by Samyang:

The lens’ motor can focus to a distance as close as 25cm (9.8in). The company bills the model as suitable for shooting interiors, as well as architecture, landscapes, and other environments in which a lightweight wide-angle lens would be useful. The Samyang AF 18mm F2.8 FE lens is available to pre-order for $ 399 USD; the shipping date is unclear at this time.

Sony has unveiled two new APS-C lenses at an event in New York today: the E 16-55mm F2.8 G and E 70-350mm F4.5-6.3 G OSS. Both lenses offer dust and weather sealing, and use XD linear motors – a first for Sony’s APS-C lens lineup.

The 16-55mm offers a 24-82.5mm equiv. range, with an overall compact design – it weighs 17.5oz / 494g and measures 100mm in length. It provides a minimum focus distance of 0.33m / 1ft, and will go on sale in October for $ 1400.

The E 70-350mm provides a 105-525mm equiv. view, with stabilization built in. It’s also relatively compact for a lens of its telezoom class – it measures 142mm and weighs 22oz/625g. It will ship in November for $ 1000.

Panasonic Lumix S Pro 24-70mm F2.8 to ship in October for $2200

28 Aug

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_1553724933″,”galleryId”:”1553724933″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Panasonic has announced its fourth L-mount lens: the Lumix S Pro 24-70mm F2.8. The company is making no small claims about it: promising superior bokeh and sharpness. To that end, the 24-70mm uses 18 elements in 16 groups, including three aspherical lenses, four extra-low dispersion lenses and one UHR (ultra-high refractive index) lens.

As with the other ‘S Pro’ lenses, the design is certified by Leica (though the lens isn’t branded as Panasonic/Leica, since Leica designs its own L-mount lenses).

Panasonic also touts the lens’s high-speed autofocus. The system is powered by both linear and stepping motors, and a focus clutch allows for quick switches between auto and manual focus. The lens is dust and splash-resistant, as well as freeze-proof to -10°C (14°F).

The 24-70mm F2.8 should will offer video shooters benefits such as silent focusing, and Panasonic claims that the lens exhibits minimal focus breathing.

The Panasonic Lumix S Pro 24-70mm F2.8 will cost $ 2200 when it ships in mid-October.

Press Release

Panasonic Launches a New L-Mount Interchangeable Lens for the LUMIX S Series Full-frame Digital Single Lens Mirrorless Camera

LUMIX S PRO 24-70mm F2.8 (S-E2470)

Newark, NJ (August 27, 2019) – Panasonic is proud to introduce a new interchangeable standard zoom lens, the LUMIX S PRO 24-70mm F2.8 (S-E2470) compatible with the L-Mount system for the LUMIX S Series Full-frame Digital Single Lens Mirrorless Camera. Developed with high-quality professional performance in mind, the LUMIX S Series of cameras and lenses together achieve uncompromised photographic expression..

The LUMIX S PRO 24-70mm F2.8 (S-E2470) is a large-aperture standard zoom lens that boasts high descriptive performance across the entire zoom range. Optical performance is remarkably high, passing stringent LEICA standards.

The rugged dust- and splash-resistant* design withstands harsh conditions and ensures versatile use for landscapes, snaps and portraits with its 24-70mm focal length. The LUMIX S PRO 24-70mm F2.8 features stunningly high resolution and high contrast at each focal length point, with a filter diameter of 82 mm and an 11-blade circular aperture diaphragm. The full-range F2.8 high-speed aperture provides smooth defocus gradation from the focus peak to the neighboring area of the image to achieve a beautiful bokeh effect as well as a rich perspective.

Comprised of 18 lenses in 16 groups, three aspherical lenses and four ED (Extra-low Dispersion) lenses effectively suppresses both axial chromatic aberration and chromatic aberration of magnification. The aspherical shape of the lenses corrects astigmatism, achieving high resolving performance. Furthermore, a UHR (Ultra-High Refractive Index) lens achieves uniform image quality from the center to the edges of the image while downsizing the lens unit.

A double focus system combining linear and stepping motors achieves sensor drive at a maximum speed of 480 fps. This realizes fast, high-precision AF, ensuring the user never misses a photo opportunity. Focus clutch mechanism adoption enables instant AF/MF switching and accurate manual focusing. The LUMIX S PRO 24-70mm F2.8 also excels in video recording performance with a mechanism that suppresses focus breathing, a common problem in all interchangeable lenses designed for still image photography.

By 2020, Panasonic will design and develop 10 or more Lumix S Pro and other lenses, further expanding the S Series lens lineup. More than 45 interchangeable L-Mount lenses are or will be available from Panasonic, Leica Camera AG and Sigma, demonstrating an almost limitless spectrum of new creative possibilities.

The LUMIX S PRO 24-70mm lens will be available in October for $ 2199.99.

*Dust and Splash Resistant does not guarantee that damage will not occur if this lens is subjected to direct contact with dust and water.
