Sigma 105mm and Tamron 90mm Macros

Couple of questions - both these lenses get good reviews, so i wondered if
there's anything much between them. I'm after a lens for macro pics
(flowers and insects etc) for my 300D. Any preferences? Jessops have both
used - but have there been several models of each? If so, do they all do
1:1 macro shots?

And - anyone seen either for any less than £250 new?

I bought the Tamron: its lighter. It more than lives up to its reviews. I
suspect you would be happy with either, though I'd have said that in
general the Tamron build quality is a touch ahead of Sigma's - the lenses
just feel nicer (smooth, nice grip).

Not if described as 90mm f2.8 1:1 macro. There were older lenses with
different f numbers like f2.5.

ww.camera-x-change.co.uk is as low as I know.

Thanks Sophie - I have a 28-200 Tamron which seems pretty good - and Jessops
have a couple of uses 90mm macros - I shall give them a call.
And camera-x-change look pretty cheap too - £251.

 

There is a *huge* difference between the results of these lenses.

Both are very sharp. The Sigma is one of the sharpest lenses I have
ever used, and just edges the Tamron. However, the Sigma renders out
of focus backgrounds as a harsh jumble of objects, especially if there
are any highlights.

The Tamron renders out of focus backgrounds as a smooth blur. This
characteristic means that it is not only a superb macro lens, but is
outstanding for portraiture. The harsh out of focus effects of the
Sigma make it virtually unusable as a portrait lens.

I would strongly recommend the Tamron, as you are effectively getting
two lenses for the price of one. The ability to use the same lens for
macro and portrait work is an unusual feature.

 

Watch out for any old stock of Sigma 105's they'll not wortk with EOS300D (I
had to get a chip upgrade in my lens to work with my 10D)

Otherwise, been very happy with it.

Cheers,
Chris

 

I must agree, though I've never used, the Sigma lens, the Tamron SP90 is
wonderful lens for close ups and also people. My Tamron SP90 (Pentax AF
mount - lens should perform just as well for the others) is my favourite
lens and I use for 80% of my portrait pictures. It also works well for
candid work.
