Just saw someone selling D70 at hardware zone but the box design is different from what i've seen (black with gold color).

When changing lenses point the mount downwards, don't use a blower and blow into the mounting area.naviseal said:Is there anyway to prevent or minimize dust from occuring after cleaning? :think:

espn said:I have tons of it.. but since you hardly shoot at f/11 and up... nothing much to worry. Else send for cleaning everyday since still under warranty...heehee...
nokin said:espn,
firstly - can you please enlighten why dust is nothing to worry about if you shoot at f/11 and up. Does it mean that there will be effects if pictures are shot below f/11. What are the effects?
secondly - I read in one of your post somewhere that on a digital camera f/2.8 has an equivalent of f/8 on a film SLR. Can you explain the conversion of f number between digital and film? I understand 1.5 factor of lenses for digital and film but not the aperture.
Thanks.
