Well Elias, that seems to have woken everybody up from their siesta ;-)

Thanks everybody for all that, very interesting (although some of Emmanuel's
went way over my A-level physics syllabus!) I thought the Lancia Theta was a
car ;-)

Having really only wanted to get a DSLR so I could digitise my negative film
strips to make contact sheets, the choice between a Nikon and a Canon fell
in favour of the Canon because of the availability of an adapter for Rollei
lenses. The adapter costing 10 UKP, has not broken the bank if it is a
complete waste of time. Certainly the 'cheap plastic' Canon 17-55mm zoom
gives quite good results.

In running the tests, I am surprised at the quality of even a basic DSLR
using technology is 3 years old. I do feel that the images are 'soft' when
enlarged and looking at current DSLR test reports in Amateur Photographer,
most digital cameras can only just resolve about 20 lpm whereas I seem to
remember that in the days of similar tests with film cameras, they could
resolve far higher lpm. Unfortunately I cannot find any period tests that
have these figures as a comparison.

Is my memory failing me?

John
