Listed are three zoom telephoto lenses that are readily available at a decent price; which is the better choice: KM AF D 75-300mm f/4.5-5.6, Sigma APO DG macro AF 70-300mm f/4-5.6, Tamron AF 70-300mm f/4-5.6? Also, any problems with the Sigma and Tamron mounting to a 5D?

cheap glass is exactly that -> cheap



the minolta 75-300 f4.5-5.6 ($135 new) (which i own) is 'crap'

i would go with the sigma APO (make sure you can return it if you're unhappy)



i still strongly recommend the minolta 70-210 f4 (used $175) which will give you a top quality 35mm equivalent of 105-315mm f4

Time to get my vote in, I have a 70-210mm f4,( the original crossed x model ) it is a fantastic lens. The only negatives about this lens is its bulk, big and heavy, and the fact that its front element rotates which makes polarizers difficult to use. It should also come with the original reversable lens hood.

The 35-70mm f4 macro and the 70-210mm f4 were lenses done right, not the cheap stuff that came latter. (notice I didn't say crap... oops...)

Virtually every new lens specified for Maxxum or Minolta AF will work with your 5d. The ones you need to worry about are the old lenses made by anyone but Minolta. Even then, most should work- but because the lenses were reverse engineered instead of licensed they may not always be forward compatible.

The problem is quickly becoming the lack of KM 5D cameras. Most large retailers are already out of stock. I am sure this will affect the lens market, at least for awhile.

Lenses have already really increased in value- even since Christmas. On one hand since I am buying lenses I'd hope the trend slows. On the other hand, it'sa good thihg to show demand for the lens.

Been researching.* What I have gathered is the zoom telephoto lenses with a fixed aperature of f/4, are definetly a better lens than a lens with a variable f/4.0-5.6?* But that doesn't translate to the variable aperature lens doing a decent job for the money,* just not the results of the fixed aperature?* So, a Sigma AF APO 70-300mm f/4-5.6 for the money,* should give me nice results to my untrained eye?

If you keep your costs very low for this lens, and get one that is (reletively) compact, it wont hurt as bad if you find that you need to upgrade. When you upgrade, you'll still have this lens for when Light and Inexpensive is the order of the day.

Trying to compromise,.... well, its a compromise. Your probably stressing image quality more than you should, none of them come with vaseline smeared on the front element.

PS, the bigger aperture is usually better since it helps in low light or for throwing the background out of focus, but its not the reason that a particular lens has better image quality. Thats more coincidental than anything.

Considering the Sigma lens is $200 new, what would be the next option for an equivalent zoom telephoto (70-300mm) will good/ great quality?* Trying to stay as close to the $200 range.*

I looked the Sigma 70-300/f4-5.6 APO II up on dyxum.com and there are some reviews you might want to read.
