Canon Issues an Official Rebel T6s/T6i Advisory: ‘White spots may exist on the optical layer’

canon-t6s-t6i-recall

Looks like Canon is about to pull a D600 with their latest EOS Rebel T6s and T6i Cameras.

About 10 days ago Roger of Lens rental shared a post where he found a big batch of Canon T6s’s and T6i’s to have a weird pattern on one of the glasses on their sensors:

The bottom line is that 4 of the Canon T6s and 2 of the T6i cameras we received had to be sent back because of a defect in the sensor stack (the layers of filter glass over the sensor). This is out about 10 copies of each; the others were absolutely perfect

Now Canon issued an advisory that acknowledges the issue, explains how to detect if a camera is of a bad batch and instructions on how to approach support for a free repair:

This Canon 1200mm f/5.6L Telephoto Monster Available Now at B&H for $180,000

Canon_1200mmIn case you missed out on the NASA 2540mm f/8 lens that was recently sold on eBay, B&H have what might just be the next best thing – the super rare Canon 1200mm f/5.6L EF USM autofocus telephoto lens.

The lens will cost you as much as a US Navy Warship, but will get the job done when you just can’t get close enough.

With only a dozen or so of these beasts ever created, the proud owner will be in the company of National Geographic, Sports Illustrated and probably a few spy agencies.

Photographers are invited to get a look at the lens at the New York superstore, and take a selfie with it if they don’t happen to have the necessary funds at hand.

radioSTROBE is the World’s First Off-Camera Speedlight System

radioSTROBE_1One of the first things photographers hear these days after they buy their first speedlight is to avoid mounting it directly on the camera.

Using off-camera flash has become widely popular in recent years, with many accessories designed to adjust the hot-shoe mount device to work better remotely, but that’s exactly what they do – adjust an existing product to work differently.

Raman Evazians decided that photographers deserve a dedicated off-camera flash system specifically designed for their needs, and that’s where the radioSTROBE comes in.

The two-part system comprises of a flash unit and an advanced commander, and promises to be the first and only lighting option for off-camera flash photographers.

Sony’s New FE 90mm f/2.8 Macro Lens Takes On Canon’s 100mm f/2.8 In Lensrentals’ Resolution TEst

We got a pre-release set of Sony FE 90mm f/2.8 G OSS Macro lenses in for preliminary testing last week, and I was kind of excited about this lens for a couple of reasons. First it simply gives me a nice short telephoto prime option that has been lacking in the lineup (although the Zeiss 85mm Batis lens will be coming along fairly soon). Second, it gives me a true macro lens at the focal length I prefer.

I hoped that the combination of a good macro lens with the A7r sensor would turn out to be a winner. We used our Imatest lab to compare Sony 90mm f/2.8 G OSS lenses mounted to Sony A7r cameras, and compared them with Canon 100mm f/2.8 IS Macro lenses shot on Canon 5DIII cameras in our Imatest lab. (For those who are curious, we can’t test Sony E mount lenses on an optical bench because the electromagnetic focus system requires electrical power to operate. Until we do some really geeky, overly complex engineering modifications, the optical bench isn’t an option for Sony E mount lenses.) It would have been nice to also compare with a Nikon D810 and Nikon 105 f/2.8 Micro lens, I know, but our time is limited.

Adobe’s GPU Acceleration is Not That Great After All. Yet.

Adobe_CC

One of the celebrated improvements in Lightroom CC is the faster performance, said to be up to ten times faster, thanks to the software’s ability to leverage the graphic processor unit (GPU).

A few days after the official release, however, an Adobe engineer shared additional information regarding GPU acceleration and turns out it might not be all that great. Not right now, at least, and not for everybody.

At the moment GPU acceleration is only available in the Develop module, and even then not all editing controls enjoy it.

Additionally, while GPU implementation offers no advantage for some functions, certain others will actually take longer with the acceleration enabled.

This information also applies to Camera Raw 9.0 for Photoshop/Bridge CC.

The Sony A7r II Seems to Boast a 59 Megapixel Sensor

A7r_IIA few days ago we shared a photo that seems to have been taken with the Sony A7r II and uploaded to the Zeiss Lenses’s Flickr account.

The photo’s resolution indicated it was captured using a 56MP sensor, but the irregular image ratio suggested that the sensor is most likely even larger and that the photo was cropped by Zeiss.

A new image, with EXIF-data intact, reveals the latest sensor packs a whopping 59 megapixels.

Keep in mind this information has not been confirmed, though there are several good reasons to believe it is true.

Timelapse Showing High End Retouching using Affinity Photo

Ever since Affinity Photo was announced we were wondering how it will match up to Photoshop. Dracorubio took it for a round and was ok with it, though not overly impressed. Now photographer Felix Barjou gave it a spin for a full retouch session.

The retouch is sped up to about two and half minutes and for me it was not trivial to see any major differences in the workflow vs. the predominant Photoshop alternative. Can you?

Felix tells us that “This software is pretty cool. The corrector tool is more powerful than Photoshop, but some small things are missing, like invert a layer mask, keyboard shortcuts for wacom users and such, but it is still a beta version

As a PSA, Affinity Photo is still available as a free Beta, though we aren’t sure what ill happen to all the beta users once the software is completed.

Will the Canon 1D X Mark II Offer the Best DSLR Sensor Ever Made?

1D X Mark II Sensor

For a while now Canon users quietly disappear whenever dynamic range comparisons or sensor ratings come up.

The Canon sensors’ dynamic range is one of the main reasons why its flagship camera, and overall highest ranking sensor, is located in the not-so-impressive 35th place on DxoMark’s list. In fact, it shares that spot with Nikon’s $500 amateur D3300 camera.

All this could soon be dramatically changing if the recent rumors regarding the 1D X Mark II are correct, and Canon might actually dethrone the D810.
