Skin tones, la di dah landscapes and other irrelavancies.
For the purpose of photographing watches, features such as the user memory presets and hot swappable flash card get my Minolta vote.
As Puggy has shown in his tutorials even moderate cameras can produce more than adequate watch pics.
I'm reminded of a quote by the late great Jeff Cooper when discussing pistol calibers (a similarly hot topic amoungst shootists) "a smallbore champion equiped with his favoured pistol is far more effective than a baboon in a medium tank"
And yes its all about light...........max d.o.f. , min iso, aperture priority, w.b. , remote shutter release & big heavy tripod too!
