Philip. And anyone else. How do you find the a7 compares with the NEX7? This is a key question for me as it is becoming clear that the new cameras are no better with LM mount wide angled lenses than is the NEX range. However, they still have interest for me because they can use legacy SLR manual lenses at their correct focal length without worrying about the issues that affect Biogon type lens designs. That said, I would see little point in upgrading from my NEX 7 unless there is a significant uplift in sensor performance with regard to IQ and low light behaviour. I am also very interested to know if you find the EVF in the A7 to be an improvement on that of the NEX 7, particularly in low light where the NEX7 EVF is pretty poor.
On another matter dpreview has just done a fascinating studio comparison between the a7, a7r, d800 and d7100 in jpeg and raw. There is a large number of iterations both for ISO and for cameras and the widget allows you to focus on different areas of the very comprehensive studio scene for comparisons of absolute behaviour. these are shot with adapted fast 85mm lenses for full frame and 50mm (75 eq) for crop frame, all at f5.6. Unfortunately there is no option to include the NEX-7 but the NEX-6 can be included and has significantly weaker behaviour than the a7(R).. However, I expect that resolution on the NEX-7, with its higher pixel density than even the a7R, would compare very favourably with both new cameras, albeit with a cropped perspective. The jpgs are good but clearly there is a lot of noise reduction going on. The raw files give a much better indication of comparative strengths. Interestingly, in many ways I think this demonstration, admittedly studio testing rather than real life, tends to favour the a7 rather than the a7r. The Canon 5D3 comes out very well, rather better than the D800 in my view. I was also fascinated by the poor comparative performance (in my opinion) of the RX1R across the ISO range to the extent that I wonder whether it has been mis-focused. http://www.dpreview.com/previews/sony-alpha-7-7r/6
Added comment:
I went to our local stockist and tried out the A7 and have now been able to compare the NEX-7 and A7 with real life photos. Direct comparison is still not possible for me because I have no way presently of converting the A7 raw files and jpg vs jpg may also disguise differing internal algorithms. However it is evident, whether comparing LR4 adjusted Nex7 raw files with A7 jpgs or jpgs from each camera , that the IQ from the A7 is significantly better at mags up to 100% (I saw no point in going further). By comparison the Nex7 files are muddy and lack clarity. I took the comparison photos within 15 minutes of each other and used the Rokkor-M 40/2 CLE at 5.6. ...Show more →
Pretty odd. Look at the D610, looks sharper then everything. I find it hard to believe the RX1R does this poorly, it's one of the highest rated lenses on DXO, something odd with this test for sure.
Great set nico images, I like the slightly muted processing. The 35ZF seems to be a great option for f/2. I was on the fence about that lens but I went for the 35FE to have an AF lens. It would be interesting to see a comparison.
Thanks glad that you like them Sean - the 35mm f2 ZF does work great although it is quiet heavy!
I have the 35mm FE on order and can't wait to compare it against the Zeiss 35mm f2
Tried the Nikon 28mm f1.8 tonight but it is a pain to manually focus on the A7R because of how the focusing mechanism works despite being a very good lens otherwise on the Nikon D800E.
Ended up ordering a Leica R Elmarit 28mm f2.8 vII from ebay will post some images as soon at that arrives too it is supposed to be very close in performance to the Leica M Elmarit but without the smearing.
The VC 21mm 1.8 you have there seems to be a great performer considering it is a rangefinder lens. Waiting to see a few more sample images if you have any from that lens combination!
A couple more with the Zeiss 35mm f2 wide open ISO100 on the A7R which I find is so much better for manual focus than the D800 - colour is also better
Of course new camera comes and I get struck down with the flu. But I felt well enough this morning to venture across the street to the local park with A7r and the CZ 50mm Makro-Planar ZE. Nothing really special but I wanted to test the system a little more. Here are a few.
Great shots everyone. Keep 'em coming (i need something to drool over while I wait for my A7R in the states). lostinjapan, hope you're feeling better soon.
Yes, the CV 21/1.8 looks surprisingly good. Do we know if these images have been cropped to remove magenta banding / vignetting or are they framed as OOC?
Phillip,
Liked your "duck" shoot with FD lens thanks . Patiently waiting for my new "pocket" camera A7 arrives along with few lenses FE35 and FE28-70mm.

Hi waterden, I've done post processing on these to pull back some vignetting and I did a quick and dirty in lightroom for the magenta colour shift by playing with the hue and saturation in the magenta colour channel. My CV21 samples above haven't been cropped.
The results at 100% are really stunning which these resized images don't really do justice.
