Slide Copier Prototype - using Macro Ring Flash

Slide Copier prototype
Using an inexpensive Phoenix RL-59mi ringflash and a Minolta macro lens on a Sony DSLR to copy 35mm slides.
The copy stand was a bargain on eBay - a Jessops 3500 (LPL 3301D) black and white enlarger with the lamp housing and condensor assembly removed.
The negative carrier from the enlarger is also useful for holding the 35mm slide.
Phoenix Ringflash
Note this flash also lets light into the centre of the flash.
Ring flash face down on white paper
The flash shines down onto the white paper to give a very intense bounce of even white light upwards.
Enlarger negative holder on ring flash
The negative carrier from the enlarger doubles as a slide holder and mask. It is only laid on top of the ring flash at this time, but eventually an adaptor ring will be glued to the mask allowing it to be screwed onto the ring flash.
Slide on holder
The slide to be copied sits on the mask over the ringflash. Registration pins or guides have still to be manufactured to give easy alignment of the slide over the mask.
Complete setup
The Sony A100 DSLR with Minolta 100mm f/2.8 macro lens is mounted on the copy stand.
Note this photo does show the camera at the correct height, it does not show the lens at its correct focus distance of 1:1.5 on the macro scale. (This magnification is required to fill the frame of the smaller APS-C frame of the DSLR with a full frame 35mm slide.
After setting macro lens to 1:1.5, the camera is focused by moving the rack up/down on the copy stand.
Manual focus and manual exposure of 1/160 at approx f/13, ISO 100 with anti shake off is typically used.
A remote cable release or the 2 s self timer should be used to eliminate any vibration.
A sample scan
Slightly sharpened in iphoto but otherwise as it came out of the camera.
Obviously needs cropped and straightened, but once I get the slide holder registration pins it will be much easier.
Slide was on Kodachrome and was shot in 1982.
