Okay, I'm planning to get a 7D body soon before month end. I've been researching (budget-wise) some inital zoom lenses I'll need, and I've come up with the following. Any suggestions or need to knows about these lenses much appreciated:

Wide-zoom:
- KM AF 24-105mm f/3.5-4.5 (D)
or
- Sigma 24-135mm f/2.8-4.5 Aspherical IF
(24mm wide is good enough for now, but don't want less wide-angle)

Tele-zoom:
- KM AF 100-300mm f/4.5-5.6 APO (D)
or
- Sigma 135-400mm f/4.5-5.6 APO Aspherical

I'm actually leaning towards the Sigmas, but don't have any actual experience with them. If the KM lenses are really better, I'll have no problem getting them. And I'd prefer just a couple lenses right now to cover my focal needs. Any info, advice or other good 2 lens suggestions appreciated! :idea:

don't forget the 1.5x digital factor - (35mm film/APS-C sensor)

the 24mm lens becomes a 36mm

the 400mm lens becomes a 600mm



THE APERTURE REMAINS THE SAME !!!!!!!!!!!!!!

Yeah, I know - down the road I'll pick up a wider angle zoom. But the 36mm will do me for the time being. I was more curious on the lens choices, as the Sigmas are a bit cheaper than the KM lenses - but I've heard AF is noiser in the Sigmas. But if the KM's are all-around better lenses :?, I'll go with them.

there is fantastic minolta maxxum glass on the used market dirt cheap:

28mm f2.8 prime $125

50mm f1.7 prime $75

35-70 f4 macro $90

70-210 f4 (not the 3.5-4.5) zoom $180

if i were buying now i would start with the new KM 28-75 f2.8 (D)

and a used 70-210 f4



you would then have 42-315mm range with extremely good quality glass and would only need one additional w/a lens

I really wanted to start with at least 36mm wide, and wanted at least 430 telephoto. I considered the f/2.8 28-75, but for my needs I won't need the speed at that focal range. The 24-105/135 would be my main walk-around lens though, and that's why I wanted more range with that lens. The extra 4mm of wide angle really helps out. But thanks for those suggestions, I did consider them. For sports and range, I may eventually go with a fast 2.8 zoom - the Sigma 70-200mm f/2.8 EX DG APO and a 2x TC would be a nice setup for that, it's just kind of big.
