Just remember, you get what you pay for. I thought I'd go the cheaper route and get the Tamron 200-500mm for my Canon, and it went in for service twice the first year I had it due to a manufacturer defect. I actually did not have it in my hands for 4 of the first 12 months I owned it. It's nowhere near as sharp at 400mm as the Canon 100-400 is at 4000mm, let alone all the way out at 500mm, and now I'm likely going to have to pony up the $1,600 for the Canon lens on top of the $1,000 for the Tamron that I very rarely use anymore.

Thanks for all the info guys, I think I will have a talk with the misses tonight and see what the boss will allow.

I still have the lens, but I had a some problems with it. It had problems with the lens contacts, that it would loose contact with the contacts on the camera body causing the lens to loose power. Also the lens barrel would slide down when aiming up. I sent the lens in to be repaired and they fixed the lens barrel but said the contacts/lens mount was fine. They thought the problem was with the camera body but I don't have that problem with my other lenses.
The main problem is that the lens has soft focus at 300-400mm and it is slow acquiring focus (at least on the D80, I haven't tried it with the D300s). Plus the Optical Image Stabilization is not as good as Nikon or Canon.
The first 4 images are from El Centro 2009. With the original scaled image and a 100% crop (the first cropped image being the bad shot and the second cropped image being the "good" shot).
The poor quality could have been due to problems with my Nikon D90 in addition to the soft focus of the lens. (I have sold my D90).
The last two images were taken late last year out at LAX after the lens was repaired (taken with a Nikon D80). To show the soft focus at 300mm.
I could have gotten a bad lens.

Quote from: tstbell on January 26, 2010, 11:11:55 PMHmmm, that is disappointing to hear, but thanks a lot for the information. That is what I love about this site, I can get info like this. I can't always trust Amazon reviews, like all the great reviews for the 50-500mm Sigma lens, which i thought it was terrible at 400-500 range (which for airshows is what i want). So let me ask you what did you end up doing with the lens? Did you sell it? Looking online it seems that that is one of the positives about buying one of these lenses, is that you can get most of your money back online if you decide to sell it. Any chance you can share some of the "Bad" and "good" shots you got with that lens tstbell?
I have the Sigma 120-400mm and I've been disappointed with the lens. It has soft focus and needs lots of light. I used it at the 2009 El Centro Airshow and I had few keepers from the show. So now I have been using my Nikon 70-300mm lens for aircraft.
Quote from: Fernando Sedeno on January 26, 2010, 11:35:45 PMTokina is not an option for me since they don't make a lens that will mount to a Sony camera. Maybe it sounds like I should just cough up the extra dough and get the Sony 70-400 lens.
Seems to me that Tokina is WAY better than Sigma?
Good to know...

I was originally looking at Sony's 70-400mm f/4-5.6 G SSM Lens, but the $1,500 price tag is shying me away.
