The full range for aperture is 2.8-32. I know that F controls the dept of field and I want to play with that. Does this mean that the lens ring will only have adjustment from 3.5-6.3? So there will not be much room for dept of field experiments? OR the range 3.5-6.3 means some lens quality range and it would still have full scale 2.8-32?

your numbers start blurring above so ill start again
at 18mm you will have a bottom end of 2.8 and a top end of say F16-F22
as you increase zoom the numbers will go up like say at 250mm it will be F5.6-F32 say
so if your at 18mm you can use F2.8-F22 and all the stops in between
play with the camera in manual and you will find the limits
without looking up the lens cant be exact but that should answer you

Inexpensive zoom lenses have a maximum aperture that changes as you zoom. This lens has a maximum aperture of f3.5 when you are at 18mm focal length and f6.3 when you are zoomed all the way at 250mm.
The smallest aperture is probably f22.
By the way, apertures go beyond 32, many 4x5 lenses go to f45 and f64.
