Originally posted by hinman I am pretty happy with Tamron 70-300 Di LD 1:2 Macro. I bought it used in marketplace from a great soul for $90 -- I think I may have bought it from Eastern Shore Charlie. Yes, PF can be a problem with the lens but I learn to cope with it in f/8.0 and smaller apertures (bigger f numbers as in f/8.0, f/11.0) and up ISO when in dimmer light. I also use PFree+XnView for PF removal. Here are few blog posts with test pictures on the lens
I used it for everything from tele to close up and portraits. On a limited budget, I can recommend this lens with the noted caveats on PF but if you learn to cope with it, it is a value lens to have.
I want to add that both the Sigma and Tamron are fine lens for the price. Best image quality should go to DA 55-300 but you are paying for twice the price and the lens come short in missing 1:2 macro that you have in the Sigma and Tamron. I own the Tamron lens and I have seen great pictures from Sigma and my forum friends do have the Sigma, even the non-APO one, and I have seen great shots from both the APO and the non-APO versions of Sigma.
As many have said, the Tamron do have a bit of more occurrences on PF but the sharpness and cheaper price in Tamron overshadow the weakness for me. Sharpness is my 1st criteria in choosing a lens, and I deal with the PF with techniques in knowing the lens and PP with tool.
Few test pictures from my Tamron 70-300 Di LD
PF/CA happen in similar shots but I overcome in PP and shoot it in
different timing, angle, lighting, ISO, smaller aperture
very reasonable for my $90 to do 1:2 close up
I like sharpness that I can depend on
@ 160mm
@ 300mm
@ 300mm
And I used it to the extreme on Birds In Flight as well as Bee in Flight
@ 300mm in macro
Color fringes: you can see them on lower left white edges of the flower
I use it for both flowers & bugs in hiking, very versatile to go from portraits to tele and back to close up
Range from 70mm to 150mm serve me well in portraits
@ 120mm
@ 133mm
I can recommend without a doubt that both the Tamron and Sigma will serve your purpose well. If PF bothers you, go with the Sigma and if sharpness is key to you and you want a cheaper lens, go with the Tamron.
Thanks,
Hin
