A7r with RF glass

LOL well I know how we'll find out now ;)

the picture that seems to be emerging: 28 and below M240 is really superior. 35 and up, with exceptions, but not many, A7r has superior IQ to M240.

It will be some time before that's totally confirmed. It may be that the 240 still has superior edges at wider apertures with the 35s and 50s.

But on the flipside, the A7r centers are deep and detailed at all FLs. This is evident with downsized images.

Now the A7r may not like floating elements....we need to see a lot more 50lux shots.

In short, 35s like the cv f/1.4, better than I dreamed. cv15 worse than I expected, as are a bunch of very nice RF WAs.

With luck I'll have a camera by the end of the week. Then I can report on zm18 and 28 cron and v3 elmarit. I also have cv 21/4 but I don't see the edges ever coming in on that, or any of the tiny cvs including the 35/2.5. They we be fine with an APS-c crop though.

Obviously colorshift will need to be dealt with on a bunch of lenses.
 
So tge retro focus RF lenses are looking tge best.
I suppose there may be a run out on of production lenses like the MATE, WATE, Hexanon dual 21/35 and Hex 28mm f2.8.
Maybe Zeiss will add a few distagons to the 18mm they currently offer.
Distortion from Retrofocus designs is going to be easier to fix than all that edge mess the symetrical schemes are showing in these samples so far.
 
Or you're willing to shoot your expensive RF lens at f/8 all the time and carry a tripod with you. Or just shoot auto ISO to 12,500?

or you get a nice inexpensive nFD 24/2.8 and wait for a killer native, which won't be long in coming.

here you can see that lens and other slrs:

Then you shoot RF 35 and up.

Or you don't sweat the corners on your wides and love the centers.

Lots of options.

and if I want to shoot birds, I hook up the 70400g and go to work.

Are there results using Cornerfix on the A7r or A7 yet ?

Cornerfix has long improved many super wide results on the M9 / M240.

LOL not sure if you realize the A7r has very fast AF--fast as any DSLR when used with LAEA4.

Hi Stephen

the easiest workflow for colorshift has yet to be determined, but cornerfix certainly will be one option.

Lightroom has an edge correction plugin now which some swear by.

Capture one has something similar

If a shooter is OK with jpeg output, the in-camera lens profile app would be easiest.

Since the camera can shoot jpeg+raw it may possible to have a corrected jpeg but also the raw in case the correction is not adequate.

Brian Smith told me the sony raw editor actually does see the colorshift adjustments made with the lens profile in camera app, but this is not confirmed.

I think there will be some very detailed threads on these options once the camera is out and shooting. :)

Eventually the RAW converters should be able to use information that is available in the RAW files. It may take some time to get support, though. (Looking especially at Apple.)

Well I'd say it's true for 35/2 biogon, even on M9, glad to show comparison shots if demanded

Matter of perspective, I guess. The Leica 35mm Summicron isn't perfect on the M9 either, and is best corrected with 6-bit.

I'll agree that for every FOV the biogons cover, there are better designs in terms of performance on digital.

Summicron ASPH does better than older versions, the 6-bit can help bit on vignetting, but if corners are losing too much IQ, 6-bit is not that useful.

Anyway, I was quite disappointed by 35/2 corners, lol

You must be talking about subject isolation and low noise thanks to a large sensor, a great EVF and the ability to adapt virtually any interchangeable lens that has been produced in the last 70 or so years, right...?

Nope. Center sharpness of the same -the only virtue displayed and claimed so far and hardly the sole component of great imagery. The little Sigmas trump them from what I have seen (the entire frame as well). That is a shame, because with better results as well, I will keep my Nex-5n for a fraction of the price until the a7 sideshow makes the center ring. I am pretty confident that will be done with natives, not legacy lenses. By the way, that is exactly what happened when I set my adapters aside and dropped a Sigma 30 on a 5n.

(Disclaimer: These are just my opinions. I have and use several Nexi, an RX, and Sigmas and have now canceled an a7r preorder based on what I have seen in these threads.)
 
soo soo controversial :)

This is super clever. Buy a camera that is very small compared to a DSLR. Then you notice that the AF is not super fast. Buy a huge adapter and lenses and now you have a comparable performance... and a comparable size and weight. Hm.

Yeah, how silly of them to make it versatile like that, esp for people with 3-4k in sony ziess glass.

this guy just hates it:

I'm glad all these threads with images show up :) Let's me see what works and what doesn't a custom tailored RF - A7R setup. Cheers.
