I plan to buy a good zoom lens for under $1,000, I am looking at three Sigma lenses for my Minolta 5D:

70-200mm F2.8 EX APO DG Macro (I like it's fast F2.8 and macro)

100-300mm F4 EX APO (I like it's zoom range and sharpness)

100-300mm F4 EX DG APO (same as above but for APS-C)

or any other sharp zoom lens?

Thanks

Dyxum.com rates them all between 4.95 and 5.00 (5.00 is the highest score.)

PhotoZone.com rates thembetween 3.68 and 4.27 (The highest score for any lensis 4.83.)

Though choice. Wish I had to make it.

I bought the 70-200 2.8 DX EG APO HSM macrofor my D200, as did Garykohs, and I really like it. It is a heavy lens, 1 lb. 15 oz., but is fairly short, and balances well, especially using a grip. If you get it, spring for the 1.4DG EX TC to go with it. The D200 doesn't have the AS like KM and Sony, but I haven't found that to be a problem so far with this lens.

What type of shooting are you mainly going to be doing as that will be the only thing to make the call between the two options (a DG lens is not for APS-C but rather is optimised for digital but will also still work fine with 35mm/full frame)? As for the Macro it's marginal with the 70-200 so depending on your other lenses this would not be a huge selling point for me (again depends on your needs).

I had the 70-200 when using a KM5D and it was one of two lenses I got when I switched to Canon as I 100% needed the f2.8. If you don't then the results from the 100-300mm are going to blow your mind even with the 1.4x TC fitted it is one nice lens. I'm spoilt now as I have the 70-200mm f2.8 and the 120-300mm f2.8 from Sigma which was the reason I moved from KM as the 120-300mm f2.8 was not an option.

I want to shoot in door low light conditions, therefore Iwant a fast lens F2.8, I don't know the F4 would be fast enough. And I also like to shoot birds and moon, 100-300mm plus the 1.4x or 2.0x TC would be better than the 70-200mm with TC, I also want the sharp sharp lens, the 100-300 is sharper than the 70-200, but not much. I need to be careful to make the decision to pick one between these two lenses since they are not cheap. I know both lenses are good, if the F4 is fast enought for low light, than I will pick the 100-300mm, hope more users can give me more opinions. Thanks a lot.

For indoors you might find that even f2.8 is not bright enough depending on the shutter speeds you need. For my indoor sport work unless I'm in a really well lit gym I use the Canon 50mm and 85mm f1.8 lenses. You are in a very difficult situation I know so I hope that others come in with suggestions but if low light is important get the 70-200 and a 1.4x tc.
