A skylight filter is a slight warming filter, used to eliminate some of the
blueish cast when shooting outside, especially on overcast days. Many
people leave it on the lens all the time, as a lens protecter. That's why
I wondered if your friend used one.
I still say you need to use the same film, and process at the same lab in
order to compare. Also, a very slight difference in exposure could also
cause this. Compare the light meters. Do you shoot in auto or manual?
(most auto cameras are stepless in auto, while in manual you can only
adjust the exposure in 1/2 or full stop increments). Does he shoot in auto
or manual? Do you have any 3rd party K-mount lenses to compare the Pentax
glass too?
