Hi all

Anyone got one of the new Plustek 7200 dpi film scanners. Is it any good.

Thanks

Paul
 
Noticed it has no ICE and does not claim a very high DMax although I applaud
them for not basing DMax simply on the number bits like most other vendors do.

This should spark good debate among the resolution freaks!!

It appears that it will be available "the end of July" ...and I found a bit of info using
my "friendly local search engine" ... although no user reports or hands-on reviews showed
up in the first few pages.

(1) Too bad it's not Medium Format.
(2) ICE doesn't seem to be available
(3) Silverfast SE is furnished ... no upgrade to Silverfast AI is offered.

Why do you put review in ""? I found the review to be quite useful and
honest.
For those not able to understand german:
1. Colors are good (especially slides, negatives only if you know your
film type) thanks to Silferfast.
2. dMax is quite bad, and even worse: dMin is too high -> neither
highlights nor shadows will look reasonably good.
3. Resolution is about 2900dpi with some good will, but you seem to have
to scan with 7200dpi to get that resolution -> really big files
4. Not exactly fast
5. No automatic film transport
6. Slide holder seems to be fine, film strip holder not really,
especially with curved film.

So it's not top notch, but on the other hand it's more or less the
cheapest film scanner available, leaving the reflecta 1800 and clones
out.

My word, a 200MB file (at 7200) to get resolving power of a 28MB file (at
2700). You'll need to spend the difference in scanner price on hard
drives!

Can't possibly be of any use - my Canon scans to 4000 dpi and grain here is
the limiting factor - you'll just get the film grain in more detail!

One can down-sample to the limiting resolution, after capturing the
resolution in the first place.

Somehow the whole concept just doesn't jive though.
If scanning at 2700 won't give line pair rez one would expect at 2700, I
really find it difficult to believe that the 7200 setting would either?

Grain visibility is not the limit of resolution. Grain was visible in
my 2700ppi Nikons, but the 4000ppi scanners bring a lot more detail (and
actually make grain *less* visible). A quick look at the film data
sheets will show you need a lot more than 4000ppi to get all of the
resolution off even conventional colour film emulsions.

Correct, although the combination of:
Camera shake, and
Camera lens MTF, and
Film MTF,
usually limits the effective system resolution offered to the scanner.
Camera shake is potentially the most destructive of them all.

Including the unavoidable scanner MTF that results to something in the
80-85 cycles/mm range at best. This is of course based on films
normally used for pictorial imaging (e.g. Provia).

A very high (effective, not nominal) scanner resolution does help to
reduce grain aliasing compared to scanning at a lower effective
resolution (although scanner optical limitations can function as
AA-filter).
