PeaceKeeper: Appears the same as their other MF 14mm f/2.8's, but it seems it has one more aspherical lens. Old ones are "two ED lens elements, one hybrid aspherical lens element and one glass aspherical lens element", while this has "14 elements in 10 groups, 3 of which being aspherical and two extra-low dispersion".

I wonder how much of a difference it will make... I looked at the 14mm before I bought my 12mm f/2.0, and the distortion was horrific.

I really can't wait to see reviews/comparisons of these lenses, and I do hope DPR follows up on some of the release news.

You have not looked at the images......

The lens is about 1 inch shorter that the old E mount version. There is not built in extension tube. The arrangement of elements is different. The elements themselves are different.

These are different lenses. Similar but different

Robert Holloway: I have the 14mm f2.8 MF. I have never once needed AF or even considered why I'd need it. I'm genuinely mystified about this for my a7r2. My main use of my 14 has been landscape and astro (no need for AF and very careful composition). i occasionally shoot unusual perspective dog action shots, but DOF at f5.6 and up makes AF unnecessary. Weird.

Even in MF this one will show you on the screen the subject distance. Let's hope that Samyang place distance encoders with better precision than the MF guides which are notoriously inaccurate on the 14mm.

There is also electronic aperture control that also is comfortable even in MF. The camera can open the aperture wide while you focus and than close it as needed for the exposure.

Add that this lens is an inch shorter and it makes for quite compelling difference. As well I expect the IQ to be superior on this lens as they do not need the provision for mirror which is making wide angles very tough to build for DSLR

The design of the lenses is somewhat different. This one features much smaller flange distance.

EwanMC: The elephant in the room is the SLT-A77 II?

* Continuous AF is effective during still and video capture
* Face detection works well
* Good build quality and overall ergonomics
* SteadyShot is useful in both still and video capture
* Ability to record video using XAVC S codec

A6300 actually has dual control disks - one on top and one on back. It is very similar to A7 so switching is not hard between the two. Of course A7 series have 4 control disks so much more than any one else out there.

A6300 in terms fo ergonomics lack AF selection joystick. Fuji have shown how good this can be. Touchscreen.....well ok it is not that bad especially given that A6300 runs Android like mobile phone anyway.

It is a rather exotic nearly extinct elephant. Enjoy your camera unfortunately very few people care about A mount these days. It is commendable that Sony keeps it on life support and there are loyal fans. There is rumor of new full frame coming after a68. I guess DOR can make comparison between that future Sony and Pentax K1 in "battle of the endangered species"

Boss of Sony: Micro 4/3 cameras (in particular the more compact MFT camera bodies) are much more enjoyable to use than either the Sony or Canon APS-C cameras, because the lenses are so much smaller and cuter (and have very good IQ too)! MFT kit lenses are also better than the Sony and Canon kit lenses.

Sure there is Nikon and Fuji and Leica and Panasonic and plenty other cameras not part of this comparison. Thanks for reminding us and this is really not point of this article that compares two well balanced APS-C models for they are worth

Timbukto: No mention of rolling shutter?
http://www.dvxuser.com/V6/showthread.php?303559-Measuring-rolling-shutter-put-a-number-on-this-issue!

A6300 1080p quality not good but rolling shutter performance is good in that mode. 4k quality very good, but rolling shutter performance is some of the worst.

Other alternatives - NX1 great 1080p quality + outstanding rolling shutter performance, and most of the Panasonics.

Other good choices for rolling shutter, A7RII in 1080p or even Nikon D750.

NX1 while Samsung still made cameras had the worst rolling shutter. A6300 beat it in this regard and is now holding the rolling shutter champion title by a thread compared to the aged Samsung

Henrik Herranen: Pretty balanced article, but there are two points that I think could have been better.

Page 2: "In this instance, the a6300's finder is around 20% larger than that of the Canon. Its fast refresh means it's better able to help you follow the action than ever before."
This is my opinion not true at all. While fast refresh may make a6300 better than some other mirrorless cameras, how could it compete with the natively zero lag of an optical viewfinder? EVFs have some advantages over OVFs, but following action definitely isn't one of them.

Page 8: "While Canon's APS-C lineup isn't quite as comprehensive as its offerings for full frame, it's still pretty comprehensive, especially when you include those full frame lenses that remain useful on the smaller format."
I find this a bit of an underhanded way of saying that Canon has the most versatile native (EF, EF-S, TS-E) lens selection of any camera maker in the history of cameras. Nikon is the only one who comes even close.

- Henrik

Luckily all Canon lenses work perfectly well on A6300. I being Sony user since 2006 have bought a bunch of these Canon gems recently. Canon do make credible competitor to Sigma too.

It boils down to preferences at this stage.

It is commendable that Canon made so much progress in 80D. I was feeling they are loosing their grips and am happy to see 80D does so well. It seems Canon sensor division now is gaining speed and soon we may have some credible competition to Sony sensors.

Kiril Karaatanasov: The TTL one works with Sony too.

The non-TTL manual version supports HSS!

Yep HSS works on both versions.

I thought it is important to share that the non-TTL version has HSS as it was not obvious from the article.

rrccad: Kind of a weird article.. when both cameras are around a year old.

People still buy them, no?

Some reviews come out year after the release, so this is not strange.

In reply to:

ozturert: "I think" BSI tech is not that useful (when it comes to image quality) in larger sensors because the electronics that are moved to back do not cover very large area. In smaller sensors they make more sense to me.
But then I may be wrong...

Yes you are wrong. For example when you use adapted lenses from Leica the light incidence angle in the corners is not perpendicular so the electronics in front do mess up the image quality - color shift, vignetting etc.

Also A7R2 is amazingly clean at high iso like 6400. On A7m2 it is barely usable.

What does the statement below mean? What are the exact things A7R2 does better with adapted lenses? I know one - A7R2 AF with green mode on Metabones covers most of the sensor where A7m2 is more like DSLR that has AF points in the central third.

"more complete support for third-party lenses"

PS One more difference adapting Leica lenses works better on A7r2 i.e. less color shift and vignetting.

This time round it seems the best camera would be Canon Body with Nikon AF system using Sony sensor......

Weirdly the sensors of both flagships are quite mediocre relative to much cheaper models - 10 stops dynamic range is complete joke in 2016 - it more like 2006 performance. While Sony's top of the line A7R2 uses really low low end body design that is easily beaten by 6D or D750 in durability, ease of selecting focusing points, 2 card slots, moisture resistence etc. etc. I use A7m2 and 6D or D810 or A7r seem to be much more reasonable cameras than going to the top of the line that delivers much disappointment in the sole aspect that really matters - image quality.

Can those dual camera phones shoot 3D? Or measure distance?

Peiasdf: Expensive for what you got but if you haven't been around a latest iPhone or One or S/Note, it might suite your need.

The OLED is not Samsung or LG but some budget last gen Chinese knockoff. The SoC, RAM and storage are all pretty slow so the battery wouldn't last long.

Typically slower phones drain the battery less. Your post does not make much sense

Kiril Karaatanasov: Is there Eye AF in live view?

Thank you guys! So Canon have really made this smart. Great to hear.

I assume that micro adjustment does not really matter when using liveview.

If not too much to ask can you also clarify the servo AF functionality in live view mode. The review says "Unfortunately, focus locks as soon as you hit the shutter, so you cannot track a moving subject, or get continuous AF during bursts. A shame, given how good Dual Pixel is at subject tracking.". So no servo AF in live view at all? or is there tracking until the first shot i.e. no tracking during bursts?

Kiril Karaatanasov: Is there Eye AF in live view?

@Dale Baskin where would the Canon focus with 85/1.2 if the subject is turned slightly to the left or slightly to the right and down - cheekbone, near eye, nose, far eye, jaw....It does matter.

I know that on sensor AF system like dual pixel never err and that is why I dropped DSLR few years back.
