slartibartfast · 01-11-2012, 04:07 PM

which are the Sigma equivalents to the Tamron AF 17-50mm F2.8 and Tamron 70-200mm F2.8 and what is the difference (except price

)

thanks for your help!

The Sigma.. 17-50 and 70-200 lol. The Sigmas have OS and HSM and are more expensive. The Sigma 17-50 is a bit sharper than the Tamron, and vice versa for the 70-200.

The pre-OS/HSM version of the Sigma, the 18-50mm f2.8 EX DC MACRO is a very close equivalent to the Tamron 17-50mm f2.8,
this lens is not longer in production but regularly seen for sale in the forum's Marketplace.

I have both the Tamron and Sigma,

The Tamron is slightly sharper at f2.8, and the colours are warmer, but build quality suffers.*

The Sigma has a nicer 'feel' / build quality to it, but colours are a bit 'cold' and tends to flare a bit more.*

*my copies anyway

Both had to be sent in for warranty repair/adjustment within the first year of use,

the Sigma for something loose in the focus mechanism
and the Tamron for the outer zoom ring that 'disconnected' from the internal mechanism

They are both very close in performance but do I prefer using the Tamron over the Sigma.

Thanks for that review based on extensive personal ownership! +1 to you.
