Scanning Microfiche lense

Post by Hasher » 01 Nov 2009, 04:40

Hi Guys

Since my bookscanner is almost at an end (Just waiting for cameras) . I wanted to start a new project for scanning in microfiche that I have . For the younger crowd who dont know what a microfiche is ,like my nieces and nephew, heres a picture.

The basic lense used on a microfiche viewer is 48x magnification . I am looking for a lense that i could attach directly to a camera to produce this magnification.

Hope someone here would know how this could be done :-D

Why wouldn't you just use the lens that's inside a microfiche reader? It should be spec'd perfectly for the job.

There are some lenses that are well-suited to this work. The Nikkor 60mm macro is a good one, it is able to make a nearly 1:1 image of my slides on the sensor.

I suppose its marrying the old viewers lense to a camera. I will look at the lense you suggested. Thanks Dan

Its a bit like bookscanning as I will use the same software to post process :-D
