Title: Good in Principle
Review: I bought this device so that I could use my Nikon D70 with 18-70mm f3.5-4.5 lens. The kit states, correctly, that it will fit this combination and includes the necessary adapter ring. What Opteka do not point out is that the large diameter mismatch between the camera lens and the copier means that, if the zoom is set to make the slide fill the sensor, the edges are badly distorted. Zooming out to around 50mm solves this problem but means that only about 70% of the sensor is used, with consequent loss of resolution. Attaching it to a lens with a smaller frontal diamter will ease the problem, so the lens supplied with the D50 and D40 cameras will be more suitable.It takes a bit of experimentation to get good bright results but the potential is there.
Is the review positive or negative?
