Sigma EX 70 F/2.8 or EX 105 F/2.8 Macro lens??

Looking for my next lens for macro stuff as well as portraits inside and out. Anybody had good/bad results with these EX DG lens from Sigma?

I do not own either one, but from the reviews I read, the 70 is supposed to be the sharpest lens sigma makes. the 105 is a great choice as well.

if you want it for portraits as well as macro, then I would go with the 70. the draw back is if macro is your main focus, you will not be able to stand as far back from your subject as the 105... inportant in insect macro, etc.

I would not over look the tamron 90mm 2.8 as from what I have read, that is the sharpest lens avalible period. I would likely choose the tamron if I had the money
90mm could still do portraits, but not in close spaces.

good luck with your choice

let us know how you make out

cheers

I bought the Sigma 105mm and have been very happy. I wanted a short fast telephoto prime that could also do Macros. I already have the Tamron 28-75mm f/2.8 as well as a MF 135mm f/2.8, so the Sigma fits right in the middle (and does 1:1 Macro!) I'm still pining for a 70-200mm f/2.8, but the 28-75mm, the 105mm, and the 135mm will hold me over until then.

The two galleries below were all shot with the 105mm -
Schuykill River Park 03-03-07
Mill Grove 03-13-07

(Except the sunrise pictures in the second set, that was my Tamron)

Despite the hype regarding sigma 70 macro, I saw little difference in quality difference between 105 and 70 macro photos on line.

Sure Tamron is very very sharp with a different kind of contrast and colour rendition comparing to DFA 100 macro. I had opportunity to test it out - it is a very capable lens

hi,

I have the sigma 105 - it's sharp and works well (its my 2nd one, 1st one went when I was broke but both were good). Just about everyone says that there isn't a bad macro lens, sigma tamron or pentax (or vivitar / kiron etc) and personally autofocus at 1:1 is a bit of a joke (told it is same for all). But although it is good I am looking to change it in a few months to the pentax dfa 100 because of the weight (and the 70mm is heavier) I like to travel light and find I shake less with a lighter lens.

Thanks guys for all of the remarks, but seems we've left out one part of my orginial question - what about portraite work outside? How do these lens work at portrait work? Maybe I'll post another thread asking just that.

Thanks again!!

Greg, if you look in the first gallery I posted, you will see some "sorta" portraits (with Farm Animals). I think it does very well. I would find 70mm a bit too short (and I already have my Tamron 28-75mm).
