Yes I started with 35mm. And used colour reversal exculsively.
Still do.
At a later stage I purchased a Hasselblad, and still have it.
And still use it as a back up for my borrowed Fuji S2

I still prefer to use the Hasselblad even tho I receive a lot of flack from both Models and especially from other Photographers.
Things like.....will the pictures come out in colour?
Or....hell! still using a film Camera? (very common from Canon DSLR users)

That Hasselblad has never missed a beat........But the Fuji which is only about 3 or 4 years old, one dial has aleady broken plus the main switch is now faulty. This Camera is manufactured by Nikon by the way not Fuji.

Used film.....still do.
