If comparing these 2 definetely Tammy alot better...price also cheaper but i recommend you go for Sigma 70-300mm APO

For tripod, bring one that more firm and stable, you won't want your few K's drop cause using cheap and unstable tripod right ?

@goodmorning

How about getting some better tripods? Such as velbon,manfrotto or gitzo.. Although those cost more, but it's worth paying.

i'm at the same spot, tamron or canon? i did some research and read a lot of reviews.  my personal conclusion is tamron is slightly better than the canon. both are soft at 300mm end. tamron has macro, which is something i want. tamron is rm550, canon is rm600 and sigma is rm730.

i also think so at first

Added on August 24, 2007, 2:57 pmA month or two back i check, price is like

Tamron Di version - Rm580-600 or Rm680-700 ( cannot remember which one) - Made in China
Sigma APO version - RM730-750 (Made in Japan)

Canon, i heard Rm8xx (Dunno made in where)

Some ppl don't prefer Sigma not bcoz of the price but the after sales service since they dun have local distributor here like Tamron, so if lens got issue need to send back to Singapore for warranty claim.

One more thing, aside listen ppl said/suggest. Go TRY out the lens buy bring your camera along...dun look at the output from LCD. Transfer to PC to judge ! 

Here are some pictures taken with sigma 70-300:

PS : I was previous comparing these 2 lens (Tammy vs Sigma)...but till now haven't buy since budget use on something else more important ...i will get Sigma if buy !   

the prices i got is in KL. haven't hv the chance to test both lense together but did a few shots with the canon 75-300mm III usm. can't say anything becoz nothing to compare with. i'm thinking of going to get later today. want to go to fireworks competition this weekend.
tamron has service center locally, i think it's in Kota Damansara, Selangor

i'm owning the canon 90-300 USM which is more or less the same as the 75-300 usm besides the range that it covers, and i'm also owning the sigma 70-300 APO. in terms of output quality, sigma win hands down.. but in terms of operation, my 90-300 USM focus much faster under lowlight condition, and the sigma will hunt around having hard time to focus.. but then, under low light condition, these tele lens wouldn't be useful unless ur subject is static, and u have a good tripod with u.. hand held shooting @ 300mm under lowlight is going to be blurry.. planning to let the 90-300mm USM go for cheap.. PM me if anyone is interested..
