Can you post a picture of this lens and the camera it attaches to?
I'm ready to try this and post my dies! Shocked Smile

On a related topic, has anyone heard of a way to mechanically convert a 35mm film camera, like a Canon FT-QL, to a digital format? I have a great set of lenses with this old camera and I'd like to know how to use them for Micro-photos! Brick wall


I believe the majority of normal (non-wide, non-tele) lens will fit Smile
I use 58mm focal length lens

It will be better if the first glass of add lens larger than camera lens

I was given one of these a few months ago:




I see there is a new one out with 2meg sensor and up to x400 zoom.
Mine is 1.3 sensor up to x200


here are two shot, one is of an eprom through the top of the quartz, and the other is a pentium wafer

Not bad, but not as good as other methods.

U80701 in real use - M10 CPU, soviet PCB, East German 256K DRAM, mysterius T-1 chips:



And the chip with round heatsink above U80701 is probably 1807VM4 FPU
