Can't wait to try my TS-E lenses on it and compare the results.
The oversized image circle and exit pupil location of the TS-E glass should play very nice in the corners where others have to contend with steeper angle difficulties. That is a combination that will be tough to beat if their offset sensor can do what it claims. Add in the absence of an AA filter and the 17L TS-E and 24L TS-E II should be smokin' on that sensor.

I'm not sure why people are saying these cameras are competitively priced. Yeah, A7 is cheaper than D610 and A7r is cheaper than D800, but those cameras have insanely complex mirror assemblies and OVF prisms and are largely hand assembled. I bet Sony makes literally double on an A7 what Nikon does on a D610.
Actual manufacturing cost is just one part of the equation. Canon and Nikon sell far more 6D's and D600's then the number of A7's that Sony could sell. Moreover 6D/D600 build on a long series of similar cameras that these companies have been producing for a while, and also get to share many of the technological components with other higher end full frame bodies from these companies. For Canon/Nikon the R&D cost of making 6D / D600 must have been very small. And lastly these companies make a lot more money on the larger arsenal of lenses and accessories that they sell to go with these bodies.
You are comparing the cost of a low-volume seminal product with a mass-produced mature product. And while there is no OVF assembly to make, high quality EVFs aren't cheap by any means and there is also the cost of miniaturization to fit all the electronics into a significantly smaller body compared to a big DSLR. I suspect Sony is eating up all the R&D cost to keep the price attractive.

DSLR lens would not have that steep of an angle since the rear element can't sit that close to the sensor. The WA problem is most prominent in small RF lens.

I would be very much interested in seeing your Leica R result on the 7R. Which brand of the adapter you're going to get? I really want to see the left and right symmetry issue.
For the R lenses I have a Novoflex R to NEX adapter on its way to me right now from B&H. As to the M adapter, I have a Phigment M to NEX adapter already in hand.
I will be bringing the Novoflex R adapter and several R lenses along with the Phigment M adapter and the Hawk's Factory M to NEX Helicoid to PhotoPlus on Thursday, October 24. At this point the only M lens that I have is the Minolta 40mm f2 M-Rokkor that I mentioned above. I hope that Sony will allow me to mount the adapters and lenses onto the cameras.

Per Brian Smith's dpreview post, af speed: With the 35 and 55 lenses, the A7R was at least as fast as a900 and I was told the A7 is faster focusing than the A7R.

Phigment is a very interesting one. Without the corner smearing issue (hopefully), we would have essentially the same performance as a Leica digital (or better).
As for the Novoflex, I have used their Contax, Nikon and Leica M adapter. Personally, I think the Rayqual (from Cameraquest) or Metabones (too bad they don't have the plain vanilla version) is better in term of construction. Novoflex used only 3 screws to hold the front mount (Rayqual and Metabones have more). My Novoflex does focus past infinity while the Rayqual is spot on. But again, I'll wait and see your result. I'll make up my mind after that.

The announced native lenses are a bit disappointing. Slowish primes and long heavy zooms. A fuji with say the 35mm 1.4 or the 18-55mm 2.8-4 would give roughly the same capabilities as the 55mm 1.8 or 28-70 3.5-5.6, at smaller sizes and lower prices.

17mm or 24mm is not normal or telephoto by any stretch. That and we're talking FF, not APS-C. Having a rear element set farther back from the sensor will yield a different angle than one set closer.

I think most here are interested because of the possibilities for adapted glass. I ordered body only and am not likely to pre-order any lenses.
As well, the current Fuji sensor wasn't my cup of tea, in spite of their well-thought out glass selection.

Yes, Fuji is the master here to produce such small sized high IQ lenses. But by the look of it, the 55/1.8 might be better than the 35/1.4 WO. Stopping down, it would decimate the 35/1.4 across the frame based on the MTF. But real life shots might not show any huge difference. I guess if I pick Sony over Fuji, it would be because of different reasons and not because of the size and price (FF would never be cheaper or smaller).

Rusty, I think you misunderstood me. What I meant is that as the rear element sits further away from the sensor (just like the normal and telephoto rangefinder lens), the incident angle would be more likely perpendicular to the sensor than if it sit too close to the sensor. That's why I said most of the color cast, corner smearing issues happen in small WA rangefinder lenses, and not the big SLR WA lenses. So even if the TS lens performs well on the 7R, it would not be an indicator of the WA RF performance.

I will have to check more carefully, but I thought that my Novoflex Leica R to Fujifilm X adapter focuses to infinity. I am not sure about the Novoflex Leica R to M4/3. The Novoflex adapters use 6 screws for the Leica R mounts.

I understand. For adapted lenses, I think this is going to be a terrific option. However, for those interested in a native AF solution, we have to wait and see what other lenses come up.
As for fuji, with the latest XA-1 they also have the regular well-loved 16MP APS-C sensor available, so you could now pair the lenses with that if x-trans is not your cup of tea. Anyways I am digressing, the thread is about A7's not fuji!

not a DSLR killer for me, size is the only benefit imo..and I already downsized from D700/70-200 2.8 to D610/70-200F4 so it even less of an issue for me...then the cost..50 1.8 G, $220...CZ 55 for A7, $998.

Of course. FF would never be smaller or cheaper. The question would be whether you get any extra capabilities for the added cost and size. So far based on the announced lenses, the answer is not very clear for native lens users yet. Though it is true that the lenses are likely going to be better in terms of resolution etc.

I'm not really knowledgeable about the adapters and the rear element to sensor distances affecting the IQ of the images but I am most definitely drooling over this. If in the next half year it gains a solid reputation with EF and F mount lenses, I might just get rid of my D600 and go the Sony route. ( I have a couple of Canon lenses too, but haven't got a body for them -- I was waiting on this thing to come out before I make a decision. I do landscapes and portraits).

Weird, for some reasons they think Contax lenses deserve 3 less screw. I thought the 6-screw design on the Nikon is only for modern system. My bad! Thank you for bringing that up.

I meant in regards to not offering the same or equivalent kens to their fixed kens camera. They just released the 23/2 years later, avoiding some cannibalization. I agree though. Fuji had a more compelling lens lineup at launch to me.

I might be missing something, but this doesn't seem very similar to fuji to me. Fuji launched the X mount with three useful primes, a wide pancake, a fast normal, and a telephoto macro.
Sony comes with a slow 35mm and a large looking 55mm and a bunch of zooms. I bet there will be three iterations of a Sony super zoom for this camera by the end of 2015
This would certainly be a nice platform for adapted lenses. But that isn't what I'm looking for. People are getting way too worked up here. This product might dampen enthusiasm for higher end m4/3, but the rest of the mirrorless market is still wide open to cheaper and smaller competitors. If you want to use native lenses, what does A7 really get you over a Fuji?
Interesting product overall. But I think I'll wait a year or two and see what shakes out. ...Show more →
