Do NOT get the 28-75mm f2.8 SAM if you think that 18mm on your APS-C is not wide enough.
Although it is a FF lens and can be used on both FF and APS-C body, the 28mm on an APS-C will give you an angle of view that is 42mm.
For those of you who are not sure what I am talking about, turn your kitlens almost to the 50mm mark and look through your viewfinder. If you can live with that being the widest you can go, then you can consider getting the lens.
Just because it is a f2.8 constant aperture lens does not make it a good lens for you. If it does not suit your needs, the f2.8 constant aperture counts for NOTHING. Ditto for 24-70mm f2.8 lenses. Anyone of you guys with APS-C body thinking of getting that focal length, turn your kitlenses to 36mm, tape it there and use that for one week at least without removing the tape. If you can live with that, then you can get the lens.
well, for me, im quite happy using this focal length actually,
which make me have to run around n frame my picture madly =D
depends lah,
i bought this lense is because it can cover both aps-c n FF which i feels that i will be going to full frame in near future..
btw, it really have some problem on shooting group photo,
and so personally ,i think that getting an UWA will do the group-photo-shooting job nicely ~ =D
then followed with 70-200mm~
then 90mm macro
then 400mm..
and 1 more thing,
f2.8 really does well in focusing in DARK situation which 18-70 cant!
