More help needed: D mount lens for 8mm cam adapt to M4/3
Among the multitude of old-ass lenses I bought from ebay, I bought two D-mount lenses (a 13mm prime and a 1 1/2"? prime) meant for 8mm cameras. I could not find a D-mount to Micro 4/3 adapter, so I got a D-mount to C-mount little thread ring, and a C-mount to M4/3 adapter. I'm not great at reading descriptions so I got a "super slim" model that's a pain to put on my camera and I'll definitley be getting another one.
So I get my lens all jerry-rigged to my camera. The 13mm has a good amount of vignetting, but I can probably crop some of that out if I shoot in 4k. The 1 1/2" covers the sensor quite nicely.
On both of them though, they act like macro lenses. They'll only focus extremely close to the camera. The 13 doesnt even have a focus, just an aperture ring. The 1 1/2" focuses only like a foot in front of the lens.
Is anyone knowledgeable enough with lens mechanics to help me get a further focus? Is it just lens and sensor spacing? Do I need different adapters or maybe some type of speedbooster/reducer? Or is this going to work at all?
On a cooler note, I discovered I could invert the 13 and put it right up to the 1 1/2 and get some extreme macro. So if nothing, I have myself a nice macro setup I can put to good use.
