Sony’s Xperia Z5 Premium Phone: First 4K Display and Fastest Autofocus

Sony today unveiled its new Xperia Z5 family of smartphones, which breaks new ground in the camera and display department thanks to the line's high-end Xperia Z5 Premium phone. That phone features a 23MP sensor, an f/2 lens, the world's first 4K display on a phone, and the world's fastest autofocus in its camera module.

Testing the Sony a7R II on a Huge Canon 600mm Lens

Last week, we shared a video showing how the Sony a7R II has greatly improved autofocusing with Canon EF lenses using a Metabones adapter. Photographer Yannick Ciancanelli did some similar tests using a Fotodiox adapter and a wide range of Canon lenses, including the massive $11,499 Canon 600mm f/4.

Ciancanelli's findings weren't as positive as what other photographers are reporting.

Kipon’s EF to MFT Adapter Has Impressive AF Speed

Last month, Kipon announced the world's first autofocus-capable adapter for using Canon EF lenses on Micro Four Thirds cameras. If you've been thinking about picking one up, here's some good news for you: the autofocusing speed appears to be quite fast.

Japanese Kipon distributor SHOTENKOBO has released the 2-minute video above that shows some tests of the adapter using a Canon 70-200mm f/4L IS lens on a Panasonic GX7.

FoCal 2 Lets You Compare Autofocus Test Results and See Prior Tests

FoCal today announced Version 2 of its automated camera calibration software that helps photographers calibrate the microfocus adjustment on their cameras. The new update will allow users of the software compare their autofocus test results with other users and see previous tests you've run to better see how your gear is performing.

4 Mirrorless Cameras Battle the Nikon D4s in an AutoFocus Shootout

TheCameraStoreTV released this very timely video yesterday in which they putting the autofocus systems of four separate mirrorless cameras -- the Fuji X-T1, Sony a6000, Olympus OMD E-M1 and Panasonic GH4 -- to the test against the mighty Nikon D4S.

Each of these cameras have claimed at some point or another in their marketing that they indeed have the fastest autofocus, so The Camera Store's goal was to see which one could rise above the pack.

Sony’s a77 II Has Arrived, and It’s Packing an AF Sensor Worth Drooling Over

Since the last A-Mount Sony came out with, we've seen the a7, the a7R, the a7S, the a3000, the a5000, the a6000 and the a3500. But don't let the names fool you, not a single one of those was actually an A-Mount. This has led many to wonder if Sony had given up on the A-Mount.

Well, today those people have their answer in the form of the a77 II -- in other words, a resounding "No."

Canon 1D X and 1D C May Have Autofocus Issues… When Shooting Below 0° C

A report on Canon Rumors is pointing out an issue with Canon's flagship full-frame DSLR and its Cinema counterpart: the 1D X and 1D C. Apparently users have been reporting problems with the 1D X's AF when shooting in less than 0° C, and if an anonymous report sent to CR is accurate, Canon knows about the problem.

How it Works: Sony’s Super-Fast Hybrid AF Explained

One of the most exciting things about Sony's new A6000 is the crazy-fast AF system that's been built in. At just 0.06 seconds of lag, the A6000 claims the title of 'world's fastest AF' and blows most mirrorless cameras and APS-C DSLRs out of the water.

But if you're like us, you're not satisfied with knowing THAT it's fast... you want the WHY and the HOW as well. Fortunately, Sony has just released an episode of LearnTV that answers this question for you, and teaches you a few things about the different types of AF systems while it's at it.

9 Features Every DSLR Should Have Now

They say that the DSLR’s better days are behind it, but it’s still the choice for most working pros. Rapid advances on point and shoots, ILCs (mirrorless interchangeable lens cameras) and smart phones have left the DSLR looking like the camera of yesteryear, so here are a few features we think every DSLR should have now.

Rumor: Samyang to Start Making AF Glass Under a New Logo Very Soon

Third-party lenses are on the rise, there's no denying that. Between Sigma kicking large amounts of booty with its impressive lineup and Tamron looking serious with the new 150-600mm lens it recently announced, competition for space in your camera bag is getting fierce.

And apparently it's about to get even fiercer, because rumor has it Samyang intends to step its game up as well.

New Tech Totally Eliminates Zoom and AF Noise from Video Soundtracks on the Fly

DSLRs and Compact System Cameras are becoming increasingly capable video capture devices in addition to being solid still shooters. But when it comes time to focus or zoom using the lens' or camera's built-in motor, you're often left with glaringly obvious noise on your soundtrack.

So far manufacturers have tackled this problem by introducing silent focusing motor lenses, but one group of engineers is taking a firmware-based approach that seems to work just as well (if not better) and might someday soon do away with zoom and AF noise entirely.

Video: Comparing Canon’s USM and STM Lenses Using the 70D’s Dual Pixel AF

As Canon has begun focusing more adamantly on making its DSLRs capable video capture machines, the company has had to adjust its glass to match. The new Dual Pixel AF on the 70D is a great improvement (check out these videos if you doubt that) but if you're planning on shooting video using the autofocus, you'll probably get to the point where you have to choose between buying a USM lens and an STM lens.

When that time comes, the video above by YouTube user marconilanna should make that choice a little easier by showing you the differences -- in both noise and speed -- between one of Canon's STM lenses and a few older USMs.

Check Out the Canon 70D’s Dual Pixel AF Technology In Action

At the beginning of the week, Canon introduced the latest and greatest addition to its APS-C lineup of DSLRs when it debuted the Canon EOS 70D. In addition to the standard specs you would expect to find in any of Canon's APS-C cameras (the company has gotten some grief lately regarding its lack of innovation) the 70D packed one very impressive improvement.

The 20.2-megapixel Canon-designed sensor inside features something called "Dual Pixel CMOS AF": a new autofocus system that promises to vastly improve the speed of Canon's live view and video AF capabilities. And now, we get to see it in action.

The Magic of Firmware: Canon EOS M AF Speed Boost Seen in Videos

Earlier this month, Canon announced that there's a firmware update for the Canon EOS M on the way that will boost the mirrorless camera's sluggish autofocusing speeds by up to 2.3x. Given that AF slowness is one of the biggest gripes EOS M owners have with the camera, the news was likely music to many a EO M owner's ear.

If you want to see what this 2.3x looks like in real life, Korean photographer Daero Lee has published a number of comparison videos showing updated and non-updated EOS Ms focusing on things.

Sluggish Canon EOS M Autofocus Will Be Up to 2.3x Faster with Firmware Update

There was a great deal of excitement when Canon entered the mirrorless camera market with the EOS M last year, but much of the buzz evaporated when people began putting the camera through its paces. Although the camera features impressive image quality, one of the biggest issues is the sluggish autofocus that often gets in the way of capturing "decisive moments."

If you're the not-so-proud owner of a EOS M who constantly grumbles about the AF, here's some news that'll be music to your ears: your camera is set to receive a major AF speed boost by way of a firmware update.

GhettoCAL: A DIY Lens Calibration Tool for Microadjustment-Enabled DSLRs

It’s fairly well known that not all lenses are created equal. Put that in combination with manufacturing variables and lenses don’t always perfectly align with the camera mount. Generally the differences are minor and for the most part negligible, but I buy old Minolta lenses from eBay and I want to get the best bang for buck out of them.

I started making micro adjustments to my lens/camera combinations when I first got Sony’s a77, and have now micro adjusted all my lenses for the a99 and D3. After reading what the Internet had to offer regarding “micro adjustment” or the “fine tune” functions higher level DSLRs offer, I quickly printed off some charts similar to rulers and taped them to my wall to start making adjustments.
