Phillip only had the A7r for a short time; I don't believe he can get access to an A7r again to run another test.
gotcha -- well, I'd still be interested to see the rejected 50 Lux shots (I'm hearing conflicting things so far, and even this questionable sample could be helpful.)
The Leica 28/2 has less color cast than the 28/2.8 ASPH does on the Nex-7 (at the same apertures), so to me that tells me that it has / will have less smearing as well.
turnstyle, the 50 Lux ASPH on the A7 turned in decent performance stopped down. At f/2 the Sony Zeiss FE55 walks all over it and is 1/4 the price new... but "walks all over it" is very situational. If shooting at distance wide open is your thing and you want detail to hang in at the edges then the FE55 is a better bet.
In the centre, at distance, both are comparable. At least on the A7 they are. Don't forget it may well be that the Lux 50 works perfectly well for your application and tastes but fails miserably at contrived tests.
Check the rest of Ron's samples - he has some close in shots (only on A7) if you want to check them out at the link I included up-thread.
On the plus side the native FE55 looks great; some manual focus classics look really good too. At least there are options.

I want the 50 Lux to be killer on A7/A7r -- this is driving me nuts!
Same here, but if it's not good, I won't feel too bad not buying it right now since it's soo expensive.
Thanks for the tests Phillip. Too bad about the lux50, its rendering is a bit special. I'm glad the G45 looks like it works, should make for a very compact all purpose walkaround lens.
Not owning a 50 Lux, I'm delighted the FE55 is looking good. Mine's on order and I've a feeling it won't be a catch and release situation for me but time will tell.
What I really want is a killer 20 or 24mm prime option, SLR mounts fine with me while the wait for native lenses goes on.

That makes sense since the Elmarit ASPH shares more in common with the Biogon designs, where the Summicron, like the vIII and IV Elmarit, and the ZM Distagon 18/4 among others, as I understand it, sacrifice size for a design with less problematic angles of incidence. Though doubtfully trouble-free, any of those lenses should outperform the Elmarit ASPH 28 or any Biogon 35mm or wider.

i kinda doubt that since it doesn't look like a dog on ron's shots with the a7. i doubt it'll be worse on the a7r, but who knows.
The lens's real strength to justify its price is WO sharpness within 2/3 of frame and beautiful Bokeh in relative small size with high build quality. (at least worth $2500~3000 to me)
if use it for Pixel PP, check last mm corner or....
No, I am not aim to OP obviously. I can't imagine it will perform poor on A7R for its focal length. Just don't want create a internet gossip here in alt board. Buy it if you find it cheap....

Woof woof? I wouldn't say that without knowing how it performs on film and a digital M first and I'm guessing it does a bunch better there.
On the A7 at least, for the distance shot, stopped down the Lux 50 ASPH looks fine; wide open - not so at all. That's also the case for the medium distance foliage shot where the FE55 delivers much more even performance across the frame when the aperture is wide and even at f/8 I think it holds an edge.
Close in both deliver a good result wide open and stopped down and I wonder if we'd be able to tell which is which in a blind test. I'm not a bokeh high priest but I know what I like and in Ron's close in shots of the fence at equivalent apertures from f/2 onward the two look surprisingly similar given the very different paths these lenses travelled to come into being.
No doubt you can make pretty pichures of squirrels with either on an A7 and A7r. Woof!

My guess, given the performance on the NEXs and M9, that the Leica Elmarit-M 28/2.8 vIII or IV, will wind up being the best performers of RF 28s on the new Alphas.
Let's not forget the excellent CV 28 Skopar f3.5. On my Nex-5n the corners are without noticable smearing. Regarding smearing it is even better than the M-Hex 28 (which is a Elmarit v IV clone) but it shows more vignetting. And it is as sharp as my other 28s (C/Y Distagon 28 f2.8 and M-Hex 28).

Now I just realize even defending 50lux M may have offended you
Do you really need make a conclusion based on a single test on a single copy of each lens, at single test condition with adapter used even....
50lux have so many drawback(depend on personal preference) if you track my M thread post I have listed them several times, but center sharpness at any aperture is never one of them. I have no doubt new 55 is a great performer, but conclusion of 50lux was walked all over seems premature at best. That is exact the point I am trying to say.
Is there anything that is not proper in my previous post above make you feel I am aiming you but not the the fact?

Not sure if you are talking to me or not, but I'm definitely not offended, nor is my woof! dog lying at my feet here.
Central sharpness looks good for the Lux on the A7, that was never in question and no doubt it will be the same on the A7r.
As I said ^^^ I would not call any lens a dog without seeing it perform on its native camera but more than that, I agree that there's more to pixel peeping and edge to edge sharpness in defining what makes a lens good, bad, or great and personal preference certainly plays a big part in that determination. I used the phrase "walks all over it" in a post earlier but immediately tried to tone that down because I recognize there are many variables as to what works for any individual.
My own preference for core optics in my kit is for good edge to edge sharpness throughout most of the aperture range, so I'm liking what the FE55 is doing in that regard, that's all. As well I've owned some Zeiss wides that at times looked pretty busy in out of focus areas but haven't owned a Sonnar 50 which has a rendering I like; I was very pleasantly surprised at how nice the out of focus areas were on the FE55 on the close in shot of Ron''s, looking quite a lot like the Lux is a compliment.
With so few tests and so few copies of lenses being test the best we have now is warning smoke wafting through the trees. With some of the lenses in question there's probably a blaze burning nearby; with others, maybe not. Wait until some of us have the camera for real and can start using them and we'll quickly know what's what.

I am glad to hear that.
I myself look forward to get A7R to check few of Leica lens I have. Leica lens are always over priced, no doubt about it, but most of them at least perform. I might buy the zeiss 35 and 55 depend on how I like the system. A excite moment! maybe too excited here

I used the CV 28/3.5 extensively on Nex-5 and later on the 5n. Like the 21 and the 35, they very very sharp in the central frame, however the edges are extremely difficult to control.
If one already has the lens, it would well worth a try. But I'm very skeptical that the 28 or 35 skopars are going to have killer edges on the A7r. I hope I'm wrong.
Best hope for tiny 35 I think is some version of the summicron, or very possibly the cv 35/1.4, but the latter, as Douglas says, it's more of a "people lens" due to distortion etc.
SInce I can't really justify a 35 summicron, I grabbed an M rokkor 40/2, for which I have great expectations.
Again, all these lenses should be very good in a crop mode. I'm thinking the A7r makes a great M8
