Hi, I'm new to the forum and would like your advice regarding the Tamron 28-75 f2.8 SP AF Di lens. I have a Canon 40D and would like a reasonably priced fast lens, would this be OK to use with my camera and it a good lens to use?

Your help would be much appreciated
Denis
 
Its a superb lens! Razor sharp at all apertures, nice bokeh.
 
I used to have this lens and thought it was fantastic. Only reason i got rid of it was i wanted a lens with IS on it.
This was snapped at home using the Tamron and my Canon 30D

Cheers Guys, That great news, never owned a Tamron and was not sure of quality. I have a 17-85 Canon so lower end covered and an old 70-210 canon lens that I used with my Eos 600 film camera which covers longer distances for the moment. The Tamron should meet my needs in terms of working in dimmer light situations. I will have a look at the Sigma that you suggested though prior to making my final decision. Thats a brilliant shot I think you just made my mind up dave_bass5.

Thanks again Denis
 
Denis.
The 28-75 f/2.8 and the Tamron 17-50 f/2.8 are very sharp lenses.
Of course they aren't USM so are a bit slower to focus and a bit noisier but i never had any issues with mine (ive owned both).
And they are small, light and come with hoods. Great value for money IME.

One more to push you over the edge ;-)

IMHO Tamron generally have the best optics out of the 3rd party manufactures.

The 90mm macro, Tamron 17-50 f/2.8 and the Tamron 28-75 are easily as good as Nikon / Canon alternatives in that range optically.
 
Hi puddleduck. Thanks for the info above. I'm now 99% sold on the Tamron 28-75. Would that be equivalent to a 44 x 120mm taking into account that I am using a Canon 40D with a crop factor of 1.6?
 
You can think of that if you want, but its still a 28-75 with the edges missing really!
 
Hi 45689Ajax, The new Sigma you on your link states it is equipped with HSM! Would that work with a Canon 40D? and if not, does that mean no AF only manual focus?. Excuse me if the answer to this question is obvious to you but I'm still fairly new to digital SLR's!
 
so it crops the other way? I'm confused now I thought you had to multiply by the crop factor to get the max & min!

Should work perfectly with Canon EOS 40D.

Ignore the crop factor! Haha!
I have the sigma 24-70 at present and im really happy with it. I have heard many good things about the Tamron 28-75 put the few mm on the wider end swung me because im usually pressed against the stage when shooting.

The Tamron 17-50 f2.8, im guessing the front end doesnt rotate as it comes witha petal style hood? I may look at getting this to replace my 17-85

HSM works like IS then, so easier to avoid camera shake I presume? If that's the case it may pay me to wait until this new Sigma lens is available! As long as I can make the purchase before Christmas so I will have i for my January holiday.

Hi Mike, thanks for your reply. I have the Canon 17-85 which I find is a good lens for my landscape shots, but I want the f2.8 offered with the Tamron and Sigma lenses (at a price that suits my pocket better than the Canon equivalents). I'm not sure if the front end rotates or not on the 17-50 f2.8, but like you I would think not in veiw of the petal shaped hood. does it have image stability like the 17-85? as that is really useful and you may well miss it.
 
HSM is an internal focus motor whereas IS is Image Stabilistaion, equivalent to Nikon VR. You still have to hold the HSM lenses steady!
I have both the Tamron 17-50 f2.8 and 28-75 f2.8. They are great lenses but I wouldnt say either are "pin" sharp at f2.8. You need to close them down a bit to get the best results.
Mike, they both focus internally so the end of the lens doesnt turn.

Hi Allanm. Thanks for the valuable info re difference between HSM & IS, I suppose I would have to entertain the Canon equivalent lenses to get pin sharp at f2.8? or look for a f2 or or wider if they exist?

Thanks again Denis
 
Don't put too much relevance in statements such as "pin sharp" as they are open to interpretation!

My lens is very sharp wide open. Some might call it "pin sharp".
 
What the CA like on the Tamron 17-50 f2.8

I find it disgusting on the Canon 17-85IS, and not too wonderful on the Sigma 17-70 f2.8-4, but its alot better then the Canon

Cheers puddleduck, I must admit it did make me think I should not bother with the lens as having the option of f2.8 was my reason for considering the purchase.

Thanks Denis
 
Both my Tamron and Canon 17-55IS are (were) sharp and very, very close.
The Canon is slightly better but i found that my 28-75 f/2.8 was sharper than my Canon 24-105L.

I agree with puddleduck. Getting pin sharp images at f/2.8 or wide open is something the Tamron's can achieve. Getting this sort of shot is not always easy anyway and a lot of people blame the lens (not accusing any one here of course).

This is just a superb lens IMHO.
 
The CA performance there is alot better then my Canon 17-85IS

Right, best get saving for a zoom AND a replacement for the 17-85! Haha! :lol:
 
Thats Brilliant I'm definitely going for this now. I'm off to New Zealand in January and this is just what i need for lanscapes and some portraits while I'm out there. Thanks again puddleduck

And thanks to all of you for your helpful comments, guidance and expertise Just waiting for 28-75mm Tamron to be in stock (about 10 days I believe).

Cheers Denis

I dont see any CA on mine, either on my D300 or Fuji S3pro ( or my old D70)
It really is a nice lens, and I get similar results as Puddleducks face picture at f2.8.

For the price, you cant go wrong, you could certainly spend an awful lot more and not see much improvement!
Allan
 
CA is well controlled, and i dont see any unless i go looking for it. But it is there.
Then again, all lenses have it, some a lot more than others and its certainly nothing to worry about on the Tamron's.
I had a quick play with a canon 85mm f/1.2 recently. That has shocking CA wide open.

Was just about to PM you then noticed it was canon :(
 
Hi Guys, Thanks for all your Advice, I now am a proud owner of a Tamron 28-75mm f2.8 XR DI LD ASPHERICAL (IF) Macro Lens (Canon fit) and I couldn't be more chuffed. It's just what I needed and I'm now all set for my forthcoming holiday in New Zealand

Cheers Denis

For what it's worth, the images that I saw that were taken with the Tamron wide open were at least as sharp (to my eyes) as those taken with the Canon 24-70 wide open. I'm not talking about generic web samples here, these were photos my shooting buddy and I took.
