    A little test...

    I've recently purchased this Panagor Slide Duplicator. This object is quite cheap, the lens quality is not outstanding but it is tank build.



    My aim was to verify if the quality reachable with slides is higher than a film scanner (I use a Plustek7200). I want to show you some fast shots (200ISO and sky as light source) with some rugged sildes.
    Results have been really good.

    These are from a Fuji Velvia 100F and Contax T2: true scanner killers






    This is a crop from the last.

    These again from Velvia 100F and Minolta 35mm f2.












    With a macro lens using a flash probably I would reach better sharpness.
    The real gain of A900 over a film scanner is the lack of Dmax: the quantity of light is not fixed, we can change it as we want, and the CMOS hilight outfit helps. Shooting RAW we can remove color dominant easily, and the whole workflow is faster.

    Hi Paolo

    This is very interesting indeed. I have tons of slides (and negatives) that I keep promising myself to "digitise" but baulk every time at scanning, de-specking and everything else that goes with scanning.:sleep006:

    It looks to be a very well made device, does it only copy from 35mm or is there a variant that will copy from 6x6mm trannies as well?....I have both to digitise!
    Cheers, Dave

    I have also just done a Google search and found that the Panagor is over 25 years old....so no wonder it's so well made then. Nothing wrong with that or those images in my view.

    cool!

    This is also a great find in that, if you have enough megapixels, you can shoot 35mm chromes again without buying a scanner if you're enlargements aren't going to be huge. (or maybe if they are?)

    Thanks for sharing.

    The problem that I see in such duplicators is that the limiting factor are the optics, which are never going to compete with a good scanner, no matter what.

    Yep... The lens is not so good for detail extraction, but the tonal response is very very good. I've shot @ 24Mpixel and downsampled to 3000x2000px.

    The result is good indeed, and usable up to 15x22cm or 20x30cm.

    This bellow with a sharp 50mm lens and a flash would be better

    Re: A little test...

    Just out of curiosity, is the vignetting/falloff in corners in the originals? I was looking at one of those tubes with an eye toward knocking out the glass and screwing it onto the end of my 100/2.8 macro(it helps that my brother is a machinist). I bought the bellows setup with a macro MD lens for $90, with a MD-AF converter it will probably end up at ~$130. One big advantage is it will handle negatives as well, without modification.

    Re: A little test...

    A couple of years ago I started work building a slide copier using my A100 + Minolta 100mm macro lens, copy stand, and ring flash illuminating the slide. Unfortunately the ring flash has now failed and I cannot try it with the A900. Focus was the biggest problem!

    aye... fascinating!

    I think, all this setup is not needed anymore, except for existing slides of course.... then again, I might be wrong....
