Here's a thread for good samples of A7r performance with RF glass. Believe it or not, credible samples are only now becoming available, and most of our previous "evidence" has been hearsay--albeit from some reasonably creditable sources, like Huff. Samples have either had no detailed corners or they have been very close, like Huff's boots shot with the 50 lux asph.

Today that changes.

First lens we get to really see? The tiny and great Summicron 40/2, aka m-rokkor 40/2

peep away at

and here is the cv 35/1.2 no corners but:


Huge shout out to Martin Hertsius from making these images with the SOny A7r :)
 
That looks great. I've been watching the A7r news daily and previously had one reserved. Realizing that I've shot this entire year on film - and with Sony promising several more new cameras for Q1 2014 - I've decided to cancel the order. These photos look great...

However, being a wide-angle (18-21) RF shooter, I'll wait and see.
 
Thanks for the images.

I find the double-image bokeh of the third photo really disturbing, especially at the red collar of the gentleman in the background.
I didn't think the 40/2 Summicron did that. My impressions of the 40/2 Summicron are that it renders like the 35/2 king-of-bokeh.

Or is it just me? Or is it digital artifact?

good eye.

Actually the 40/2 is complained about by some for it's bokeh:

go down a few posts

now I know what the guy was talking about
 
yeah, i didnt like the look of that one either. the last one had an interesting look. the first two i'd be looking for superior resolution and edge performance, and i couldnt make a judgement on either issue.
 
Got a reply from Zeiss regarding adapting ZMs on Sony mirror less. A little bit disappointing. But the key is 'perfect match and best image quality', so maybe with a little bit compromise can still consider .....

One thing, Rollei is so advance, their wide angle 40/2.8 HFT Sonnar is digital ready so many years back! : D No wonder the 35mm on latest Sony are all Sonnar design rather than Biogon or Distagon .......


Dear Mr. Chang,

Thank you for your inquiry to ZEISS.

Like all M-mount lenses, our ZM lenses are developed for analogue and digital M-mount rangefinder cameras. They work perfectly on the digital Leica M models (e.g. M8, M9 and M).

Because all other mirrorless digital cameras (e.g. Sony E-mount bodies) cannot really handle the step chief ray angles of compact wide-angle M-mount lenses, there will appear a certain amount of vignetting and color shading with those cameras.
So we cannot really recommend to adapt any M-mount lens below 35mm focal length to a mirrorless camera.
For perfect matching and best image quality, we recommend to use dedicated wide-angle lenses or adapted SLR-lenses on mirrorless cameras.

Hoping to be of service to you we kindly ask you to contact us again should you need further assistance.

Sincerely,
Bertram Hoenlinger
 
Hi Fuwen,

You may already know they have a new series of MF lenses in the works especially for the A7r. These will be in addition to the Zeiss AF primes and Zooms.

That glass will take practical landscape shooting to a new level, for me at least.

For street shooting I think many zms may work fine.

I wish CV would step up and provide some very small designs, for I fear zeiss may ignor this aspect: my zm 18 is fantastic, but big and heavy for an f/4 lens.

But to be fair it seems they have done really well with the FE 35--which I would not hesitate to own except I have 6 or 7 35s as it is.

Whatever one's personal preference it's becoming increasingly clear the A7r is a landmark imaging tool. Smaller, lighter, sharper and more flexible than any camera made, ever.

The other companies are going to have to step up. But Sony does have the advantage of being a big sensor producer.

May not be the best tactic to wipe out their customers. ;)

Of course, Canon might wake up and build a new short flange RF shooting A7r killer, the tech is basically ready. Simple use of super thin glass over their sensors could eclipse A7r performance with RF wides easily. However they may not realize how that feat has such marketing potential.

RF as focusing solution may have limited appeal but tiny ultra sharp primes for full frame are like rare earth. :)
 
That last thread pretty much had me drooling at the usability of all those old lenses..
 
Drooling thread! WOW!

Drooling thread! WOW!

That thread with all those lenses tested was AWESOME! This Sony really is something special to those of us who treat lenses as our paint brushes!

Those guys did it right---well of course some nice infinity landscapes would have been more useful, but they shot some nice stuff!

And guess what: they are the first!

All these other canned "reviews" are eclipsed by a thread with some lens porn and decent photography.

I doubt it took more than an afternoon :)

And guess what again: these are the same sort of guys, like us, who showed Sony what to do with their 2010 E-Mount: toss the native glass in the trash and dust off the good stuff!

And who started moaning just a few months later: Full Frame! Full Frame! Full Frame!!

What do they say about the arc of history........

I would be happier if Zeiss were to make MF lenses to replace their current selection of WA M mount lenses, all of which barely or do not work on the A7r or A7.

They are making a line new line of mf glass for A7s in addition to AF line.

Many would disagree with your "do not or barely" remark, but everyone gets an opinion. :)

Only images will settle the matter in a persons mind, and they will come. You may change your mind- or not :)

You have evidence otherwise regarding the up to -3EV light loss at the corners, never mind the color shifts with say lenses like the 21/2.8 and the 25/2.8?

perhaps your could post links to support your contention?
thanks :)

colorshift will be correctable both in camera and PP, but edge performance is useful.

Since the camera has incredible rez and excellent iso performance light loss will not preclude good images----it may in some circumstances.

Most samples now are jpeg with early crude NR. Raws are looking much better.
