If only i could get a small 28mm lens with a DOF that worked well on the A7II I would probably sell my leica M, I have the rokinon 28/2.8 which performs well on the A7s but not so well on the A7

 

Sony really ought to create a small FE 28mm! With just two native primes (35 & 55), this system is pretty thin. According to their lens "roadmap", there are more primes on the way (21, 24, another 35, 50, 85, 135).

Not true. The Sony A7 and A7r have quite noticeable sensor flare issues. Sensor flare on Sony sensors, I believe, is worse dependent with how close the rear element is to the lens and the exit pupil of the lens. It has nothing to do with Leica M-lenses, although the further the exit pupil the worse the sensor flare is. I thought this had been discussed here. If not, then Google it and read about the problems with the Sony sensor flare. It happens with Sony(Zeiss) lenses as well and it is subpar. (Iwill have to go and reread, but I thought it was also due to the thickness of the glass, but it could have to do with other design flaws with the sensor.)

 

The too thick sensor glass is definitely the cause a falloff in resolution even in the Sony lenses. It is hard to beat the peripheral resolution of the Leica sensor because, the design needed to be thin to utilize the old lenses. The benefit was greater line resolution in the Leica sensor as compared to designs that use thicker glass. This is seen in what appears to be more falloff of resolution of the Sony(Zeiss) lenses than would be expected in tests I've read. The Leica sensor in tests I've read, continues to hold up in the periphery of the sensor and even surpasses the A7 series.

p.s. I Googled it for you:

Rick,

 

Reflection issues are much much worse with the A7 than they are with the A7r.

Where is this issue I have never found it on the A7. Yes some seem have had it but I never have. Think of the issues leica have had over the years since going digital and we have still bought their cameras with what I see as being worse problems (M8 and IR problems, M9 and colour cast on edges with certain lenses and now delaminating sensors, M240 with the strap lugs falling off and so on)

Let's get real about what are real life problems

That 28mm lens will be the cheapest lens in the FE mount and will have attachable 16mm Fisheye and 21mm converters that stack in front of the lens. This is the problem with the FE lenses, for me. Just can't get into the lenses they are coming up with.

 

The 28 Summicron is probably the best 28mm lens made. I am impressed with what Sony is doing with the & series if, you like an automatic-centric camera design, but it has to be a system with desirable lenses and so far the lenses are not desirable, for me. They certainly don't lend themselves to manual shooting.

I used to have a A7. I now have the A7S. After a long history with cameras, including a D800E, 6D, 5Dii, etc. I can say with confidence that the A7S is the best AF camera I have every used. It's bitingly sharp corner to corner and has a pop that Reichmann referred to as medium format like.

The A7 was excellent with no issues with prime lenses as I understand it.

 

This all seems very theoretical and unproven. I would stand by my statement that the A7S, apart from tracking AF which I never use, is close to flawless.

 

It may seem bitingly sharp, but so far the m240 and the 50/ 1.4 has the highest edge sharpness I've seen tested between the M240 and the A7r which is 36MP against the 24MP M240. So, it is not a case of it being unproven. Would you like me to dig up some testing results?

Well we will have to wait and see and the 28 summicron is by far my favourite leica lens. The lux 50 asph can be great but I have had so many problems with my copy (been back to leica 5 times now in as many years) and as much as I like it's signature since I have had the FE55/1.8 it has hardly had any use. Anyway I have no interest in getting into some leica/sony which is better which is worse thread as it is sooooooo boring

I do have interest in the performance of these cameras and discussing the problems Sony has had with their sensors, shutters and other problems is of interest to me.

 

Having a camera that I can use my Leica lenses on is important to me as well. I don't know anything about the A7s or the new A7II. But, I do understand that the M240 has overall better image quality in and better file adjustment ability (Leica doesn't compress RAW) and so far the sensor seems to be non-problimatic with better corner sharpness.

 

I am sorry if an open discussion between the M240 and the A7r and A7 are of no interest to you. I believe an open discussion of the problems I (and others) have had with the A7r is productive and of interest on a Leica forum.

The 50mm summilux asph is still my favourite 50mm. However the Voigtlander 50mm f1.5 is lovely and I loved the draw and contrast of the 50mm Summarit. The classic draw of the 50mm Summicron with its sharpness are also a unique combination. I guess I'll never be monogamous for 50mm or 35mm. For 55mm I'll stick with the FE for now ;)

David,

 

Here is one of the discussions on Fredmiranda.com:

 

Starburst issue with Sony sensors (A7r) how big is it? - FM Forums

 

Reflection issues for the A7 have been discussed and mentioned numerous times on FM and most of us have found much less issue with our A7r cameras than those finding the issues with the A7.

 

 

I do have interest in the performance of these cameras and discussing the problems Sony has had with their sensors, shutters and other problems is of interest to me.

Rick,

 

Perhaps not ideal and larger and heavier than you may like, but many of us have found the R 28mm f2.8 Elmarit V2 to produce outstanding images on our A7r cameras. For those that can afford the cost of entry and the size and weight, this is how many of us have dealt with this issue and problem. So, for me, I have now use the M WATE with the R 28mm f2.8 Elmarit V2 along with my Minolta CLE MC 40mm f2 M-Rokkor lens with my R 100mm f2.8 Apo-Macro-Elmarit as my 4 lens system. Frequently a 5th lens is my R 280mm f4 Apo Telyt lens and 6th lens would either be my R 180mm f3.4 Apo Telyt or my R 80-200mm f4 Vario Elmar lens. I am considering one of the M 90mm lenses- probably the 90mm f2.8 Elmarit or one of the Summarit 90mm lens for a smaller option to my Apo-Macro-Elmarit, but I suspect that the Apo-Macro-Elmarit performs better than the M options and also offers Macro capabilities.

I am not surprised that you use the FE55/1.8 in preference to the 50lux on your A7r. I would too as the 50lux just does not work on an A7r.

 

The 75APO Cron though is another matter :D

i have never tested it myself. But i would be surprised if that was the case with the 75APO Cron, which gives such outstanding results, that i have super-glued to my A7r :D

I don't have an A7r and have never expected it to work well on the A7 (though it's pretty good on the A7s). Of course the M will perform better with leica lenses as the sensor has been designed to do so. This is not the point as on the whole I am interested in the A7 series with it's native lenses and at least for me I find the FE55/1.8 to be on a parr with the lux 50 on the M and for my uses to be even better. I will now retire from this rather pointless discussion

My bad. I assumed you were implying the 50lux was 'good' on the A7r

For those of you wondering about the A7II, read Steve huff's review on the Amazon web site I was shocked to see him say that the IQ was even better than the Leica M240 as he has always been a Leica fan and in all of his comparisons I have read to date, has never said that before.

 

I can't compare to teh M240 from my own experience but I can tell you from my experience it is the best I have seen so far, easily besting the Leica T and XV I had and better than the Fuji XT-1 or the Sony A6000 which I also have.
