Well, the obvious answer is: it depends. Any particular lens you want to discuss?

Cheers,

I own two SIGMAs. One is my favourite lens. It's the MACRO 105mm / f=2.8. It has a verry good built quality and resolution is extremely good. There's no distorsion, CAs or other remarkable failors. AF is a little bit slow, since it's not HSM, but still good. AF range can be limited for non macro usage.

The other SIGMA I own just arived today. It's the 10-20mm /f=4-5.6.
Same good built quality but ultra fast HSM AF. Can't say much about optical qualities at the moment since I did not have time to test. But according to
http://www.photozone.de/Reviews/46-n...report--review
it seems to be the best wide angle available at the moment. Distorsion is verry low for a extreme wide angle.

And not to forget; both lenses are Made in Japan! All original Nikon equipment I have is made somewhere else (China, Malaysia, Thailand).

So far to say, the EX series is verry good. Taking the price tag into account they are extremely good. Might be different for the low end (non EX) series.

Here's a link to a test of its 105mm bigger brother. It looks like they have yet to test the 70mm version.

Later,
Johnny

They tested the 2.8/70mm for Canon at least:

I recently bought the Sigma 12-24 DG EX for my Pentax K10D : it is really excellent, very sharp and superb contrast, no distorsion at wide angle, a real pleasure to use.

It's true that EX series are very good, however non EX series can be poor.

Default How about the Sigma 150 2.8 Macro?

Doug,

It depends on how you'll use the lens, but the Sigma 150mm 2.8 has in-lens autofocus motor and gets good reviews. I've seen some work with it that is impressive.

Here is a link to a review for it: http://www.the-digital-picture.com/R...ns-Review.aspx

I'm thinking this will be the replacement for my 15 yr. old Nikon 60mm 2.8 Micro when I get the itch...

Choosing Sigma MACRO 70mm F2.8 EX DG will obviously a good choice. As it comes with full frame camera with the best focal length.

One thing to consider is the manufacturers like Canon have excellent service. One can get a lens repaired to specifications time and time again and the workmanship is reliable. Sigma has brilliant lenses too at good prices, but their service doesn't have the same reputation. I personally don't see the need for new sigma lenses, where I can get used Cano. Lenses and have them rebuilt or rent fabulous lenses for a shoot and return them.

But to I like the Sigma fisheyes!

Sigma also makes some unique lenses and some high performance primes. Actually, in the past years they appear to have shifted their priorities towards premium lenses.

That's true. The art lenses are well regarded. Have you heard anything recently about their service. Will Thompson won't touch them anymore because of bad repair experience. But he bears grudges! I would love to hear that they have updated their repair just as they have improved their lenses!
