Worth upgrading from a Nikon Coolscan IV?

    A few years ago I decided it was time to start to digitise my
    collection of slides and photographs collected over the last
    <mumble>nearly 30</mumble> years. So I bought a coolscan IV and made
    a start. Unfortunately other things intervened and I only got around
    to doing a few hundred.

    Now I find myself thinking of restarting this task. However meanwhile
    technology has moved on and I'm wondering if its worth looking at
    acquiring one of the newer scanners - e.g. Coolscan V with the higher
    resolution (4000dpi v the Coolscan IV's 2900dpi).

    Most of my historical stuff is slides (variety of film, but probably
    mostly Agfa 64 (I think). The more recent stuff is largely print
    negatives (Kodak 100 mostly). I pretty much expect that all future
    stuff will be digital.

    I know this is a bit of an unanswerably question, but I'm wondering if
    people think upgrading would be worthwhile in terms of being able to
    extract more detail out of the slides and print film. I probably
    wouldn't be considering this if it wasn't for the fact it would appear
    I could get a reasonable price for my coolscan IV on eBay (but then
    I'm always surprised at what people pay for 2nd hand stuff on eBay!).

    I have used many slide scanners and have owned several. I still use a
    lot of film and scan it all, so I hope my opinions may be of some use.

    There is no doubt that, all other things being equal, a 4000 dpi
    scanner will extract significantly more information than a 2900 dpi
    scanner. I have used drum scanners of 4800 and 6000 dpi, and leased a
    Minolta 5400dpi slide scanner, and the additional information
    extracted was not significant.

    So 4000 dpi is more than enough. It will give you a scanned file of
    approximately 21.4 megapixels versus the 11.3 megapixels of your
    Coolscan IV.

  3. Yes, do it, you don't want to have to rescan them again in 5 years time
    cos the resolution is too low.

    Sell the old one - as you say the resale value is great.

    It is unlikely that you will ever want to rescan above 4000 DPI.

    Thanks to Tony and James for providing valuable
    encouragement/justification to me to spend some money ;-)

    I actually dug out some old slides and after checking them carefully
    its pretty clear that the 2900dpi of my Coolscan IV isn't enough to
    extract all the details thats there. Its useful to know that 4000dpi
    should be "good enough" for all practical purposes.
