I have Sony NEX-7 I love it's image quality a lot, is there any reason to upgrade to A7 or A7R. I need for best image quality what is possible, I shoot ISO100 and mostly portraits, small groups of people.
Any hints ?

If you get bored about A7 and willing to sell it on bargain price let me to know also.

my understanding is the R is not as good with MF lenses, especially WA rangefinder lenses. plus its not as good in low light.

i have an rx1, which i believe is the same sensor as the A7, and the sensor is fantastic, anywhere up to 6400. best lowlight camera ive ever used. the evf is stunning also. the only negative is the jpeg engine stinks and you really should shoot raw. and the auto iso doesnt let you set minimum SS, which is a general sony problem.

other than that i think youll be blown away by the results, theyre just stunning. and its FF!

Thank you Tony! I do research!

It has fix lens and pretty expensive to my budget, I need interchangeable lenses, WA performance is not important, only center.

yes my rx1 has a fixed lens but what i meant was that it has the same sensor as the A7. the A7R has a different sensor which is not as good with mf lenses and not as good in low light. so if i wanted to use with mf lenses and/or i wanted to be able to sometimes shoot high iso, i would pick the A7 not the A7R.

Tony from what i have gathered around the net your first statement, the sensor of the A7 handling rangefinder wide angle lenses better, must be true, but I am not so certain about the second. Everybody thought that the more MP of the A7r should mean worse high ISO performance, including me, but over time user reports surprisingly have been suggesting otherwise, and so does DXOmark, it scores the A7r's ISO performance higher than the A7's: http://www.dxomark.com/Cameras/Compare/Side-by-side/Sony-A7-versus-Sony-A7R___916_917

With the A7 you can use S mode , Iso auto and set the aperture on your MF lens . It works great.

so do the NEXes Attila has been using, the Ricoh GXR M and I believe pretty much any mirrorless camera. A mode with Auto ISO with Auto ISO works just as well, these cameras do a great job choosing appropriate exposure by simply measuring the light hitting the sensor.

Image quality wise, the A7(R) is definitely superior to the NEX7. Most of the vintage lenses are going to become sharper on a FF sensor (except the corners at wide-open apertures).
Ergonomic-wise, not so sure but you can get used to it.

I suggest to wait until January, when the A7 II ships out in Europe.

After that all the A7 models will drop in price quite a bit and the used price will be pushed down, too.

Canon & Pentax are supposed to announce new full-frame digital cameras soon. Sensors in those might be more advanced.

Pentax is using Sony sensors and Canon is clearly behind in terms of sensor development. So the best they can do is keeping up in terms of image quality.
And those will not come at the A7's pricepoint, that will remain the cheapest FF camera for quite a while. Not much in terms of lenses (especially cheap ones) but that's precisely why it is a great option for mflenses Smile

Ergonomics is a different thing but it is challenging to make a small FF camera with good ergonomics. Software is more annoying because they could fix quite a few things in older models but only the new models get it.

"might be"" . They might be also reflex cameras which is not ideal for mf lenses.

To me the main advantage of the Sony A7/R versus NEX7 is better overall image quality,called by some "the full frame look".Just like in the film times,when bigger format offered nicer,more plastic image with wider tonal gradation.This is not of course a matter of pure sharpness/detail rendition,because the NEX7 has bigger pixel density than both of it's FF brothers.

I still keep my NEX7 as well as two NEX 5Ns,but I found over last year that I hardly use them,while both of my A7s are never redundant.

As for differences between the A7 and A7R,I prefer the former,as it is more forgiving,especially for older wide agles,older fast and older telephoto lenses.Their shorthcomings (CA,corner softness,veiling ect) are just less visible.24MP is ,I believe,more than enough for anything I do,and I hate that flapping 7R's,fully mechanical shutter

Smile

BTW: The NEX7,though a cropper, is nastier for all the groups of older lenses I mentioned above,than the A7.I avoid Leica M lenses but have more than 220 excellent/very good lenses of all major brands (Zeiss - Contax,G,ZE,ZF,Jena),Minolta MD,Canon FD,Oly Zuiko,Pentax K,Yashica,Fujinon,Voigtlander,Konica Hexanons ect),so my opinion is basing on real life experience.

If you are not in a hurry, Attila, wait for the A7 II. Kram has posted a link.

With IS, perfect for manual lenses.

Well, I had the A7R for over a year...

I loved the A7R! The shutter sound never bothered me and the image quality is insanely good when conditions are right.
I still have my OM-D for shooting with C-munts and the step up from OM-D (which is a good camera) is very noticeable.

What I didn`t like about A7R:
Huge datafiles (50mb).
Small grip, batterygrip solved it.
The 1/60 s min shuttertime in A mode with autoiso, no way to adjust min shutter.
36mp needs faster shuttertimes compared to lower resolution cameras to make sharp pictures.

FF also feels more right for all the old lenses you can adapt. I bet you will have lots of fun with your Biometar 75mm if you buy the A7 Wink

I second Lars regarding A7r.
I also have it more than a year. It is my most used body, esp when i use with canon FD and konica lenses. I don't have many wide rangefinder, but almost completed FD from 300/2.8 and wider.

In addition, what I don't like a7r:
- Noisy, not suitable for church, performance, concert
- Low burst rate, and short buffer, even the fastest card. I shoot raw. I am ok with 2-3 frames/second, but the buffer must allow me to take 20 pics.
- 1/60s is ok some times, but razor sharp is not 100%

I also like the form factor of nex5n. Combine with touch screen, 100+gram AF lenses, is very light and small for travelling.

If You are not in need to use MF WA lenses I don't thnk that an FF cam is nessesary, NEX does it's job even with it's crop factor. If You'd been a wide freak, FF makes sense.
Looking at Your kind of photography exquisite portrait with wide open teles, A7 can't do better.
Just my five cent Wink

Thank you!! Any step up in image quality VS NEX-7 , A7 or A7R ?

You'll loose a few lenses you like a lot if you move on to a A7r (like the 35mm Tevidon) as they won't cover FF, just as a reminder.

If you need the higher Mpixel count for your PRO model work, I would understand the move, otherwise just us the A7 (or A7 II)

You can just switch to APS-C mode when using your Tevidon or crop away the vignetting parts Wink

I am really impressed with the A7 II. I like the bigger size (compared to A7R), better grip, fantastic IBIS, lens komp app which writes Exif data of all the old lenses too. IQ ia a half step down from A7R, but the camera is so much better in many other areas and in my opinion the best mirrorless camera for old manual lenses at this moment. Wink

congrats Lars!

just read a report saying that the A7II will have it's IBIS disabled and there is no way of turning it on when mounting an adapted lens after having had mounted a Sony OOS lens. Only after mounting a after having mounted a Sony OOS lens. Only mounting a Sony non OOS lens first again will enable IBIS to work with adapted lenses again:
