Better accuracy actually, since the AF is directly on the imaging surface and you remove a couple of potential failure points from the light path that exist in SLRs. This is one of the best things about mirrorless cameras--no more AF microadjustments necessary.

I really had no idea. Cool to know! :)

I acquired an expensive camera so I can hang out in forums, annoy wedding photographers during formals and look down on P&S users... all the while telling people it's the photographer, not the camera.

Nice samples. I'll wait till there's RAW support.

I don't care about the 'click' - but I do care that I've not yet seen an EVF that can compare to an OVF - and if you are ever shooting a moving subject the OVF is irreplaceable. And some of you want an A7 without a viewfinder at all? Ack!

From the impressions, the Sony EVF is actually 'zero-lag' (YMMV).

In addition, I don't get the interest in hooking up a 70-200 2.8 to the A7 - once I've committed to using an 8 inch long, 3.5 pound lens, the size savings of an A7 vs. the 6D or 70D is pretty much irrelevant. Same thing with adding a grip - seems to defeat the stated purpose of the camera (keep it small and light).

Now as for the sensor - I'd be more than happy to have that. :)

I don't think many people are buying it for weight savings, most are buying it for the sensor. That said, if (smaller) Sony lenses outperform the Canon ones, you get the bonus of weight savings.

This is insanely good news.

If you download the trial of Capture one 7, you can try it out now, assuming you have some Raws on hand. Apparently it supports the A7r files, which I found out by accident, even though it thinks the camera is an NEX 7.
I tried it out myself with some ISO100 shots I had on hand and oooooh boy, now I know what I was missing. I must have pushed shadow recovery all the way and no noise in the shadows. And at higher ISOs the noise is totally random and nice and... grainy, very easy on the eyes.

I got my hands on a tif file (converted from untouched A7R raw file). I'm not entirely sure if this is the right way of testing things, but I imported the tif to Lightroom and pushed the exposure and shadow slider to max.

And yeah, your findings mirror mine. Clean clean clean! It is quite funny how the results jump out at you and leave you in a state of "surprised shock" (in a good way). :D

I have seen this kind of result before with files from the D800, but it still amazes me.

I should say that even though files at 100% shadow recovery look technically good, in terms of lack of noise and plenty of shadow detail, 50% is as far as I'd personally ever go for most subjects.
Pushing it too much makes everything look like a cartoon, similar to what you might accidentally get with HDR; at 50% recovery you see all the detail that ever need to be seen anyway, otherwise you'll be left without any shadows.

But the fact that I got an artifact that normally only occurs in HDR files from over-compression of a huge DR is a feat on it's own, I'm quite familiar with the tools in C1, and it never did that for any other camera.

Hands down the most widely useful feature of Sony sensors is their insane DR/pliability. Not many of us need 36MP, but all us can use a bit more processing latitude at least some of the time. If your experience is isolated to Canon and haven't seen demonstrations of the D800 sensor's flexibility you really owe it to yourself to see what this thing can do.

Cool! I have C7! I'll have to try these files out tonite! :) Thanks.

I'll agree with you on that. I rented an EM5 which has a Sony sensor in it and came away a little embarrassed not only about the DR, but that that 4/3 sensor was better at ISO 6400 than my 60d. :oops:
I've used an NEX and the DR issue/discussion is real.
I don't always need it, and I'm happy with what the 6d does (rented it for a weekend), but it is good to know if nothing else, for the experience ;)

I'm interested in this set up with the A7r to use it as a tech camera.
But what I'm kinda loosing interest in, is it doesn't have BULB. Unless I have miss read.

Other then that it seems like a great little camera

From Imaging Resource:

"Shutter. Available shutter speeds range from 1/8000 to 30 seconds, plus a bulb shutter function."

Don't mean to be rude but where does it say bulb?
Thanks
