My first post! Wasn't sure if this belongs in lenses or here.
I'm a happy owner of the a7r (Canon convert). Ever since the Cambo Actus was announced, I've been drooling over it. I think I'm finally at a point where I can seriously consider it. I've researched lenses as much as I can but I still have lots of questions (mostly due to budget constraints).
I mostly want the camera to be able to stitch as well as move the plane of focus. I also need lenses that will work well with IR light. I don't need super-wide, my style tends to lean toward longer lenses. Currently I have a 35 and 55 for the 35mm format. 35 is about as wide as I typically go and 55 sometimes feels a little short. Ideally I would like to have around 30, 60, 90mm lenses in the 35mm format.
From what I understand, I have two choices: 645 or MF lenses with copal #0 shutter. From my research, most 645 lenses create an image circle of usable sharpness that is at least 73mm. This should be plenty large enough for my needs. 645 lenses also appear to have a much longer flange to focal length which would mean I only need the standard bellows.
It is my understanding though that MF lenses are higher quality. I strive to reduce chromatic aberration as much as possible. I've looked at the Schneider and Rodenstock lenses but have had a difficult time researching the Cambo lenses.
Of course all lenses needs to have manual aperture control and sharpness is a must!
I understand with the actus and the a7r there might be some cross talk with movements and I will just have to play with it to see what is acceptable. I primarily shoot/print bw so color accuracy is not that important.
Finally, my budget for the whole rig is around $4,500 with nearly $2,500 going into the Actus this does not leave a lot for glass which could ultimately shut me down.
Thanks for the help! I've been reading this forum for a while, finally digging in
