I have used both Sigma's and now own the Tamron 200-500. The Tamron wins in weight,focusing speed,lack of focus hunting, and sharper at the long end than the Bigma. Steve P

Thanks, the bird one is post processed.THank you all for your contributions. That said, the bird pictures
look amazing, but the building in Brest (from Powerdoc) at 500mm
looks not that sharp. It didn't look like it was a clear day though

IMHO, it's not a waist of money!
Best regards.

[zip]Hi Pedro, I should not have said "don't waist your money" Sorry
I guess the point I would like to get across is, the Sigma has
a few things over the Tamron lens;
For nature photography, what most people would want a 500mm lens
- it is metal
- it has HSM
- it is ballanced perfectly
- IMO the image quality
for, you want to be as stelth as possible, the HSM motor is
vertualy silent, and quick to respond, this will enable you to get
photos otherwised missed with a noisy AF motor. Also, the sigma
may be a bit hevier than the tamron lens, this my not be such a
negative, I found it easier to keep the sigma steady with it's
added wait.
The Tamron is well build and has a magnesium alloy collar : this is not a cheapo lens. Metal is not always better than plastic, it depends on the plastic and the metal.Hi Pedro, I should not have said "don't waist your money" Sorry

Yes, it's better, but the Tamron AF is good for a non USM one
- it has HSM
I believe you on words, but I will say the samething for the Tamron. And the tamron is 50 % less weight
- it is ballanced perfectly
I never see a direct comparison between the two lenses. BTW speaking of image quality, optical engineers will told you that it's more simple to do a 2,5 time zoom than a 10 time one. It the tamron engineers with the same budget than the Sigma, are not able to match the quality of the Bigma, they are hopeless. That's said, I am very confident in Tamron, all the SP DI lenses are impressive and real keeper, and my first impressions and pics taken by others people, tell me that this lens is a keeper.
- IMO the image quality
I fear that some people here will hate your for that comment. BTW I think that you are right. You owned both, are a skilled photographer, and the logic back up your judgement. I mean it's logical that a DI lens made in 2004 with a 2,5 zoom range is sharper, than an older one, with an amazing 10 zoom range. I am still amazed that the Sigma engineer succeed to design such a nice lens, with such an importatnt range.I have used both Sigma's and now own the Tamron 200-500. The Tamron

the 170-500mm is slow focusing. probably the Tamron which is a new lens will focus faster.I just recently purchased the Canon 350D. So far, I have been doing
Bird photography with my Canon Pro1 + teleconverter, but I haven't
been happy with the insufficient focal length, slow focussing etc.
I am considering buying either a 400mm or 500mm lens. I was
wondering if anyone would recommend the new Tamron 200-500mm Di
lens over the Sigma 170-500mm or vice versas.
it depend..do you want to shoot wide open all the time and not worry about sharpness? even with a 1.4x teleconverter? then the prime is really worth it yes. that's my reasons for getting it. If you really need the convenience of a zoom then it's up to you.Which one is sharper, gives faster focus response etc.
For a little more money, I could buy the Canon 400mm prime lens,
which is certainly sharper, but is it worth it the tradeoff of a
zoom lens?
for birds and wildlife in general even 400mm is short. I use the 1.4x tc most of the time.mostly use it at the max. zoom anyway, but for other objects that
might come along, it might be a good idea.
yes if you use a Tamron standard TC it AF with both the 300d and the 20d.ALso, with the Canon 400mm prime a 1.4x teleextender, the f-stop
would be 8. Is auto focus still possible? I don't think so, unless
one increases the sensitivty a lot.
you can check out this TC comparison between the cheap Tamron 1.4x and the more expensive Canon 1.4x:Any comments, comparisons, experiences with the Tamron vs. Sigma
vs. the Canon prime lenses?

I love the crop factor at the long end, I hate it in the wide range
