 Re: The Voigtlander Nokton 40mm f/1.2 FE is coming! | |
I shot some new aperture series at 4 different focusing positions between hard infinity and mid-point of 5m and infinity mark. In corner-series I put the target (top of a tall building) in left top corner and in center series I put the same target at center with tripod at the same position. (I couldn't find a very good place for infinity shots on tripod where center and corner targets would have been sufficiently / equally far away so I went with separate series for center and corner). I took some shots on my mobile to record the focusing positions on all series.
It seems that at f1.2 the best focus point on my A7r (for both center and corner) is around the middle of first loop of infinity symbol again but best corner focus moves towards hard infinity as aperture closes down, around f2.8 it reaches hard infinity. This is just from initial observations with the viewfinder, will look at the photos on my PC later at home.
