#Contax 645 210mm plus#
I added a version of the same file reduced to IQ250 sensor size plus 12mm shift to all directions.Īs you can see, the image is perfectly sharp within +/- 12mm right/left OR up/down, just both together leaves the corners outside the total image circle.Įnclosed a second test image by the Contax 645 35f3.5. I added rulers to the images to better determine the sharp image circles and the total image circles. This results in images 76mm wide and 52,5mm high (stiched sensor size) with about 150 MP resolution. All Contax 645 lenses work perfectly with the FPS, the camera recognizes the lens with its correct maximum aperture, the aperture can be choosen in the FPS menu (just like with Canon lenses using the FPS Canon EF mount), the aperture ring at the lens is out of function.įor my first tests I used f11 for all shots and auto-stitched in Photoshop CS6 always four pictures in landscape orientation after opening them in ACR and doing some basic adjustments (use equal color temperature, add some clarity, unsharp mask 100% 0,5 pixel, automatic reduction of chromatic aberation):* Sorry Kim I don't own (any longer) the 45-90. I did initial tests of several Contax 645 lenses from 35 mm to 210 mm but here to mention only the wide angle Distagons 35f3.5 and 55f3.5. Of course it has the latest firmware to control the aperture (and focus if required by the user!) of the Contax 645 lenses.
The Contax 645 shift adapter is technically not yet the mass production version but the preliminary version they showed at Photokina 2014. Alpa was so nice to borrow me their Contax 645 version of the mount for the FPS which allows 12mm shift movements in all directions (left/right and up/down independingly and simultanously) and I did tests with some lenses (all with IQ180).
