russbarnes, off-topic, I was asking about Moire. But I guess you haven't seen this thread: http://www.dpreview.com/forums/post/55986323

Earth Art: That's pretty sweet! Looks like the 5Dsr has an amazing feature that adds trippy colors to black and white objects.

It's a feature! Not a bug! :)

yeah, I saw that too.

DStudio: The Nikon 85/1.8G looks more 3D than the others. But the OTUS does hold an advantage on hair and bristles. And this Canon sensor gets the most out of it when it comes to detail.

The Canon 85/1.8 is a classic example of how they drive you to L glass - by producing under-performing entry and mid-range lenses (although thankfully, they're slowly improving that situation).

I think the 85/1.8G is the easy choice for most uses. Plus, it has auto focus!

Actually Canon makes a few primes that are widely regarded as "hidden Ls", the 85/1.8 being one of them.

photogeek: The real news here is how little difference there is between $4500 lens and $500 lens at f/5.6.

the difference wide open is not worth $4000 to me.

HarryLally: The size of the RAW files from the 5DS R and D810 are interesting. Even though the Canon sensor has more MP than the Nikon (50.2 v 36.3 MP), the RAW files from the Nikon are much larger than from the Canon (75 v 63.4 MP for the Zeiss lens and 74.2 v 63.9 MP for the Canon/ Nikon own brand lenses). On the assumption that the more MP you have in an image the more detailed the image, then the Nikon seems to be producing more detail than the Canon which has around 28% more MP. And, if this assumption is correct, there seems to be nothing between the Zeiss and Canon/ Nikon lenses, at least at f/5.6.

Right, because Canon and Nikon encode their RAW files EXACTLY the same.

"Is that why no one has done it yet?" Answering a question with a question usually means you have no real answer.

"making this entire thread unnecessary" Snarky comment for someone with the company logo next to their name. Please accept my deepest, heartfelt apologies. I didn't know about the programmable dials. I haven't been paying close attention to Sony until recently because the lens lineup for the a7 was just too limited. Forgive me for valuing lenses first.

Rishi, again, what on earth makes you think a dedicated shutter speed dial would have to be limited to full stop clicks? 1/3 stops would be totally doable.

Anyway, sure, if I can program three dials to be shutter, aperture, and ISO, and have them stay that way, then that's cool.

designdog: Sony innovations are driving the industry, but I would never own this camera:

1. not really 14 bit, and lossly compression of raw files

2. where are the fast prime lenses, after all this time

3. whoops, six months later there is an entirely new body and your is out of date

4. strap a 50mm 1.4 on it, with convertor, and it looks like an afterthought

BarnET, for sure I would not have this gear if I did not make it pay for itself. But there are other parents who are into shooting their kids sports for whom a 7D2 and a 70-200/4 or even the f/2.8II is reasonable.

There are plenty of part-time pros or just parents covering youth sports and activities, myself included. Love my 7D2 and 5D3 for this.

Sports and action are still ruled by DSLRs with OVFs.

The problem with Canon's controls are that the dials change function depending on camera mode. In Manual mode, shutter speed is on the "main" dial (top of the camera near the shutter button) and aperture is on the rear wheel. In Aperture Priority, aperture moves to the main dial and the rear wheel becomes EC.

I really don't understand any opposition to an ISO dial. It's one of the main parameters of any camera! Why should we have to press a button and then turn some other multi-function dial? Bah.

Yeah, this camera won't be able to take good pictures. And 28/2, 35/1.4, 35/2.8, 55/1.8 and 90/2.8 aren't enough.

I do wish that my Canons had shutter speed dials on the bodies and aperture rings on the lenses, but I accept that this is not going to happen as the cameras and lenses were never designed with that intent. The a7 series was a chance for Sony to have a clean-sheet design.

Someday you'll learn to get out of automatic modes whenever possible. Then you'll wish for better controls.

Rishi, who says a shutter speed dial can't have 1/3 stop increments? T3, correct, but at least Nikon understands, hence the Df. Fuji and Leica understand. The a7r2 is in a market for purists, not gadget collectors. It should have real controls.

The Silver Nemesis: After reading the article:
a) Sony is (definitely) good;
b) Canon is (definitely) bad;
c) Nikon is (somewhat) irrelevant (well, except for that 3D tracking that has the purpose to make Canon look even worse);
d) Ad-hoc market analysts are giving a (generous) helping hand.

If there is a way to gain brand equity (quickly), this article should be a case study in Harvard Business Review.

it's not an article, it's an opinion piece.

JackM: So do I have this right? With Electronic First Curtain, the mechanical shutter closes to end the exposure, and then opens again to resume liveview? And this is the default behavior of the a7r2?

why would anyone ever use fullly mechanical?

1) No, Sony has first curtain simulated, not the second curtain. Right?

1st curtain causes shutter shake, so this was the obvious first step.

Someday we'll get to global electronic shutter. It can't be too far off. Current TVs now simply turn pixels off to display black, I'd think the tech is related.

jonby: Personal view:

The main factors putting me off buying the original A7R were: 1) shutter shock; 2) lossy RAW; 3) poor quality to value ratio in native lens lineup; 4) battery life; 5) concerns over durability; 6) not completely convinced by EVF over OVF.

A7R Mk II:
1) The shutter shock issue sounds like it has been resolved fully.
2) Lossy RAW hasn't been resolved (but may yet be in firmware?).
3) The native lens issue remains, but if AF is really viable with adapted Canon lenses then this is less of a problem.
4) battery life has not improved
5) durability seems to have been improved
6) EVF/OVF is clearly a matter of personal preference. I'm guessing that especially with the new improvements, I think I could live with an EVF.

For me the lossy RAW is the only remaining serious sticking block. I could live with the other issues in order to get the otherwise great image quality and freedom from lens mount lock-in.

Im not saying the LCD is better, just that it offers the the benefit of waist level shooting, which for me helps offset the fact that it's not an OVF.
