Are wideviews worth it on 1.6 crops?

[UpCloseFromFarAway]

I'm in the market for lenses for my XSi. I've got the stocker, and a 70-200L, and would like something to cover other aspects of photography. Is it worth it to buy the 28mm 1.8 Canon wideview if I'm putting it on the XSi? I hear the 1.6 crop just turns it into a 35mm mimic, so in reality, I'm only buying it for its nice aperture?

Thanks in advance! :thumbup:

It depends upon what your wide lens requirements are. 28mm was not wide enough for my needs.
28mm x 1.6 = 44.8mm
28mm / 1.6 = 17.5mm

Why would you divide 28mm by 1.6? JW?

If you are looking for a 28mm equivalent for 1.6 crop factor sensor then you need a 17mm.

Ah! Gotcha. Thanks for the help! I guess the 1.6's really shine when you attach a telephoto.

Canon makes a few dedicated wide lenses for crop sensor bodies. Two of the best would be the EF-S 10-22mm f/3.5-4.5 and EF-S 17-55mm f/2.8 IS. They will only mount on to 1.6 crop bodies though, so keep that in mind if you intend to buy a 5D or 1D in the future. If you're looking for wide on a 1.6, you don't really have any other options, but they are both really great lenses.
