Question about Kaiser Fototechnik Slide Duplicator Digital

The slide duplicator is screwed onto the filter thread of the lens. It therefore depends on the diameter of the filter thread (52 or 58mm filter thread should be used; according to the manufacturer's specifications, adapter rings can be purchased for other thread sizes). The brand of camera is irrelevant. I would recommend a zoom lens that covers the normal focal length and a slight telephoto (i.e. something around 50-80 mm in 35 mm format). This allows you to select the optimum section to capture the slide/negative.

I have no idea! I have a Canon camera. It depends on the lens circumference (front thread)

Yes, in principle it works with any camera. The lens needs a focal length between 80 and 120 mm.
Mounting is possible with a thread of 52 and 58 mm
If your lens has a different thread size, you will need an additional ekstra ring. There are rings with different thread sizes between 55 and 77 mm

The Macro adapter is screwed onto the filter thread and is included in the scope of delivery. I use an old 50mm normal lens on a MicroFoutThirds camera (equivalent to 100mm). This allows me to reproduce the slides 1:1. The quality is ok.

I started with a zoom lens on an APSC camera, set to a focal length of approx. 55 mm, which corresponds to approx. 80 mm on full format. I later switched to a 90 mm macro lens and removed the close-up lens contained in the duplicator, as I achieved slightly better results with it.

to make optimum use of the slide duplicator I also need a zoom lens with macro, I am not satisfied with my current solution.
