Working with the SONY A7r and manual lenses
I have now done the first couple of jobs with the SONY A7r, and must say I am starting to like the camera a lot!
So far I have only two lenses, the Voigtländer 35/1.4 and 75/2.5, plus a Kipon Leica M to NEX adapter that works nicely.
I shot portratis of 9 people outside on a very dark day with the 75/2.5 wide open, and was suprised to find I nailed the focus almost all of the time! Also this lens is really sharp even at f2.5, generating amazing images files with the SONY A7r.
Tonight I did an event job (mingling and big dinner) using both the 35 and the 75mm in extremely low light conditions (f1.4 1/60 ISO 3200-12800, mostly around 3200-6400). I have not had a look at the files on a big screen yet, but I did check every now and then in the camera, and was again surprised at how many shots I managet to get the sharpness right, and I already now felt that I dont really need autofucus, using eyeballing and focus peeking (no zoom om this job either, as the controlls are now on the A7 I feel its to slow to use with people) I still managed to get focus right, and felt it was perhaps even easier to use then AF under these conditions.
Here is some battery and storage data, manual focus, airplane mode:
The battery lasted for 3.5h more or less continous shooting and some image reviewing too, totaling 836 images (RAW+jpg)
A 32Gb card held 707 images (RAW + jpg)
