Fuji Superia 100 & 200. For low light use the Kodak Supra 400 or 800. The Supra quality is excellent, grain quality of Supra 400 is like a normal 200 ISO rating film!!!
Look at those most commonly used by the CS guys here and go get one and try????
I shoot Provia 100/400F. Tried Velvia and Astia... ok... but Sensei not so ok....
Fuji range of Superia films.
Yet to try NeoPan yet.... Where is Kontoya???? (sorry, what its name again??? Thanks)
