a couple of comments on the Camera Lab report. For an m43 person he does quite well overall, and lacks the now standard hyper-critical response of some others.
'The camera does not feature built-in stabilisation, so to iron-out any wobbles you'll need optically-stabilised lenses.'
No, use good technique as photographers have done for 100 years and more. He does say the shutter is quieter than the 5d3 and D800, so I guess people have a hard time dealing with a normal level of noise coming from a small camera. Comes to the right conclusion at least.
Spoke too soon, he lapses into m43 mode later in the piece:
'..coupled with the other downsides noted here prevent me from recommending it to everyone even if you have this budget to spend.' So buy a m43 guys, this thing sucks.

It's looking like the FE 55 could be the highest performing standard lens this side of the OTUS and 50 AA, which is a remarkable feat, considering the cost and/or size differences.
I really don't know where you are getting that from, because while the crops look great and highly detailed----so do crops of many lenses with the A7r.
MTFs are fun to look at, but not much use for comparison.
However, I'm always happy to be proven uninformed....
perhaps you have some links to images which support this superstardom of the FE55----shot alongside another good 50 by the same shooter?

I'm in Korea, and saw that vid last night. Upsetting, I was hoping that it wasn't going to be that hot on the market. Last week I was talking to shops in Seoul about it, and they were telling me "next week".
I won't be able to go up there this weekend, should be next weekend (23-24) that I can go to Seoul. Hopefully there are some left.
I've got a few old Canon (FD/LTM) lenses, and adapters, just waiting on the camera. Will be getting A7.
IDEALLY- i find one of those first 200 or so, used, for a discount haha.

As much as I appreciate Andrea's work on SAR, I wouldn't trust his assessment based on his MTF reading. He simply compared the MTF and arrived to his own conclusion. From A-B-C comparison (the FE MTF is similar to the ZA 135's, and the ZA 135's is supposed to be a little inferior to the ZF/ZE 135's), I would say the FE55 is roughly 10% lower than the the Otus at f/8. Nonetheless, the FE seems to be among the highest performing 50 out there. And at its current price, it offers a better value than the Nikkor 58/1.4 or the ZA 50/1.4.

I'm going on what theSuede has commented on so far, since he has access to things we don't, plus mtfs. I did say "could be," fwiw.

i would agree basing on the numerous sample images from the FE. wide open it is sharp everywhere in the frame, much better than any of the numerous f/1.4 or f/1.8 50s i have experience with. stopped down to f/8 it is near perfect, but there are a lot of other 50s in close competition there.

The other thing that I haven't seen much evidence of is the FE 55s close up performance. The lens doesn't have a floating element, so one might expect more aberrations close up and I wouldn't be shocked if there was decreased sharpness and/or contrast as well. Still it looks like a fantastic lens.

I still think the FE lenses will be great. The only thing scaring me off is the potential devaluation in resale. Aside from dollars, it is a hassle to sell anything. For example, if sigma were to release a 50/2 for half the price, i would expect resale values to drop given a viable alternative. If Zeiss is making a manual focus 50, it could very well turn out to be the lens i would want to have instead. In fact, i predict a 50% chance that Zeiss can outdo themselves.

I don't think Sigma will be making native FE lenses for a while. They would have to be unique designs (or at least heavily modified.) I guess time will tell.

Now Zeiss....that's another story.
Hmm, I don't know. Sigma is designing lenses unlike anyone else at the moment...and available at remarkable prices as well.

Well I appreciate the responses and it's going to be alot of fun to the 55 in action.

Regarding the FE 55, I have quite a good experience with Sony Zeiss lenses and how their calculated MTF translate into real life results. I would expect the FE 55 to be nearly as good as the Otus 55 both wide open and stopped down in practical use, based on available samples and MTF comparison. The Otus should have a superior performance in things like CA, coma, perhaps even bokeh, but that has to be tested separately as I don't know how to read this in the MTF

The MTF are not even available yet. Makes me think they must have a problem with that. Like the MTF don't look good and they are reluctant to post them.

I did see the MTFs somewhere and they didn't look good. Specifically the 40mm lines were quite low in the corners, but I can't find where I saw them.
p.65 #18 · Official: Sony A7 and A7R Fullframe Mirrorless
Me too Steve, they were on an asian site from memory. The 40 lpmm had a hanging tangential line, and was pretty poor at both apertures at 24mm - looks like one to see images from to verify and it will definitely be better at the long end from the MTF. Here is hoping, it is an imprtant lens for the system and needs to give buyers good reasons to part with the hefty asking price.

I could see a Sigma FE 28/2.8 and 45/2.8. Those were both smart places to fall into the NEX line-up, and, looking from an SLR-lens perspective, can be kept relatively small. If they can keep the quality-to-cost equivalent to the 19 and 30, they'd probably have another couple of hits, even if they weren't tiny.
