Lunar,
The only problem I see with using the Bagom/c-adapter/35mm lens with a long focul length, especially with a camera like the C 8, is that you don't have the adjustment in the viewfinder objective for focal lengths that great.
The B8 and D8 view finder covers focal lengths in the range of 12mm to 35mm or 50 mm. And goes down to 5.5mm with the accessory attachment. This is the SLR range I am using. So that is no problem.
Even the view finder of the D8 is framed to give you a view of up to 35mm even when the finder is set to 12.5mm.
And as the focal length increases, your accuracy for finding your subject is more crucial. Also, on cameras like that the viewfinder objective is already one with paralax.
Parallax is only an issue with very close subjects. Do not forget that most cameras were not reflex cameras quite a while ago. A reflex camera is more of a luxury actually since parallax does not play a significant part except when dealing with closeups.
so that is yet another error to factor in.
The error as I mention above plays a significant part only when dealing with very close subjects.
I know that Bolex made a paralax correction accessory for the little pocket Bolex cameras like the C 8 but did they offer any add on for significantly longer focal lengths?
As I mention above, the SLR range I am using is the same as that used by 8mm cameras (8-50).
Bolex made a parallax correction accessory (Proxirect for LA models only) that adjusts for parallax at ALL focal lengths. They also made parallax attachments for CLOSEUP work. All these should work fine with the SLR range of lenses I am talking about. although as I mention, parallax can be safely discarded unless one is dealing with a closeup situation.
