70-300 Sigma Lens - Thinking about getting it

[theantiquetiger]

OK, need some help. I got the lens in and it says "communication error with the lens, clean the contacts". They are clean. Do I have a bad lens?

NM, it is not compatible, so he is exchanging it. I am getting the Canon 75-300.

I did purchase the sigma lens. I know sigma is a cheap lens and would love to get the best of the best as for equipment, but I need baby steps. I am not too impressed with my Canon EOS Rebel XSi.

Perhaps it is a typo, but you should discard the idea that Sigmas are cheap lenses. The idea that the manufacturer of your camera makes the best lenses is bad for your photography, as well as your wallet Just like all manufacturers, Sigma make some killer lenses, and the occasional dud (especially in the old days).

+1 There are plenty of 3rd party lenses that whip the big players. Even the big players make some junk lenses.

As far as Sigma goes.

I have the
20 1.8
30 1.4
70 to 200 2.8
10 to 20
24 to 70 2.8

I am VERY happy with the line up. I did have the Sigma 70 to 300 but I was not very happy with it.I sold it pretty fast. Just my opinion.

Hope you were able to resolve you communication issue.

I have had a Sigma 70-300 APO macro for about 15 or 16 years. It was originally used on a Minolta 600si but is now on my Sony A350 where it is a massive 450mm telephoto (35mm film equivalent) Sure it wasn't expensive but is an excellent lens for its price, better than the Sony kit lenses which are somewhat soft. You can spend thousands on a lens, not everyone can afford that. I am very satisfied with the Sigma

I recently purchased the older Sigma 70-300 DL Macro from KEH - $ 45 + free shipping in Bargain condition. I was surprised to receive it in Excellent + condition with brilliantly clear glass + covers and hood. I read the review in the Pentax Forum and it scored more points than the DG APO version which a friend has, and which I had tried on my Pentax K20D earlier.
This is brutally sharp between 70-200 mm and sharp till 300 mm. Lacks a little contrast, which I can easily boost in-camera for this lens. But I am comparing contrast with a pro lens which is not justifiable. Sample shots attached. All handheld. The Mall Layout photo is at 300mm. Reduced in size from some 12-15 MB.
