Hi Marc,
personally I am debating myself to either add a 6d and a 24-70/4-0IS to my Canon kit or to get an A7 with Zeiss Zoom.
Now I understand the A7 is the sensor with more dynamic range, I am not sure which one I prefer in regards to skin color, probably both do a good job.
The A7 has the advantage to be smaller body and slightly smaller lens.
The 6d has the advantage to have faster AF also in dim light, and also for continues AF, the 24-70/4.0IS should be clearly better than the Sony/Zeiss at least is one is interested in the whole range of focal lengths and whole frame.
I also get a nice display on top of the camera where I can see f-stop, ISO etc.
I can also use the excellent 70-200/4.0IS which cost 2/3 of the equivalent from Sony (which is announced).
And for those times where weight is not so important I can allways put a 24-70/2.8, or a sigma 35/1.4 or a 85/1.2 on the camera and the weight balance between camera and body is still fine.
So for me I am leaning towards the small DSLR over the A7, but I have not yet decided.
Why do you prefer the A7 over the DSLR? Is there anything I have not recognized yet?
Maybe the difference is sensor IQ is bigger than I expect? (A7 being much better than Canon?...) How does it look if we judge combo of lens and sensor?
That's a tough call Tom. It is so dependent on personal use and end objectives. My second shooters tend to use Canon equipment and L lenses, and I do see a difference when post processing them next to images I shoot with Zeiss and Leica optics. Whether that difference is bad or good is subjective. I just sold my A900 to one of them, so that will make it easier for what weddings I still have left for this year
Frankly, I only use my A99 SLT to shoot weddings. I rarely use it for any other sort of photography. I do take it with me as back-up to my Leica S2P, but only occasionally use it.
The reasons for keeping the FF 35mm A99 are all the features that lend themselves to working a fast paced wedding shoot: Already tried and true Hybrid AF. Dual card capture. IBIS. Highly articulated LCD. Full compliment of Zeiss ZA AF lenses from 16mm to an AF 500 mirror. It is a system suited to the task, and many others if they arise.
In addition, the reason I do not see the A7R as a replacement for the A99 (yet) is the use of TTL speed-lights … what is currently available are too big on the little Sonys.
Remove wedding photography from the criteria, and the A7/A7R then becomes a primary consideration due to small size/less bulk, easy use of my M lenses due to fast Focus Peaking/Focus Mag … and simple selection of the AF FE55/1.8 as a one lens walk about. Other than a Leica M camera with a M 50mm, not many 50s deliver that level of performance at that size. Interestingly, I didn't have any issues shooting the A7R's AF in very low available light.
I don't use long zoom lenses, and in fact would NEVER spend the money these companies are now asking.:loco: My sister-in-law has a mint Canon FD 70-210/4 Macro zoom I just tied on the A7R for a few test portrait shots, and was delighted with the results. Damned thing cost less that the adapter to put it on the camera.:ROTFL:
