I am looking to go wide, since currently due to my pickiness I do not have anything wider than a 50mm prime. I am considering the Sigma EX 20mm f1.8 or the Sigma or Tamron 17-35 f2.8-4 zooms.

These would be for my 10D of course... I am looking for a fair opinion of comparison between the Sigma and Tamron zooms, and if anyone considers the 20mm prime good enough to justify the (slight) lack of versatility in comparison.

Thanks in advance!


David

EDIT: Argh! I misspelled the title. My apologies.

Here is an article on the Tamron 17-35 f2.8-4 zoom, maybe this will help.

I don't have one, but this reviewer sure likes it.

That Tamron 17-35 f/2.8-4 is also OEMed to Minolta and re-branded for the D7d

Thanks guys. Ray, I have in fact read that article, which changed my dilemma from which Sigma to choose to which lens of the three. I have found a few write-ups, but I was hoping someone around here might be able to give me some personal input on any of the three lenses.

I am interested in this topic too. I have recently bought a Canon EOS 10D and at some stage I will need to get a wider angle lens then the Canon 28-135mm I currently have. Like Gandalf 065 I'm not sure whether to go for a fixed focal length lens such as the Sigma 20mm or for a wide-angle zoom. But this is my limited research on the matter so far.....

A review of the Tamron 17-35mm;

A review of the Sigma 17-35mm;

http://www.fredmiranda.com/reviews/s...&thecat=29

A review of the Sigma 20mm f1.8;

http://www.fredmiranda.com/reviews/s...&thecat=13



Here are some samples of the Tamron 17-35mm;

Here is an example of the Tamron using a Canon EOS 10D;

Here is the Sigma 17-35mm, but couldn't find one using the 10D;

Here is the Sigma 20mm f1.8;

http://www.pbase.com/cameras/sigma/20_18_ex

And here it is being used on an EOS 10D;

Other lenses that might be of interest are the fixed focal lengthTokina 17mm f3.5 AT-X Pro and the Canon 20mm f2.8 USM. Or the wide-angle zoom Tokina 20-35mm f2.8 AT-X Pro

Let us know what you decide to purchase Gandalf and how your choice performs for you - especially if you can post some shots!

The Tamron is a digital lens only for APS-c sized camera...

The Sigma is a full-frame, and is a revised 'DG' version of my 17-35 f/2.8-4, now with a smaller front filter thread (ie cheaper polarizer to buy!):






Wide open:




BTW have you considered a Sigma 12-24mm?
... Also there's a slower full-frame 15-30mm with no 'HSM', but is a workhorse and has garnered a 'cult' status among the Nikon fans :idea:

Well.. thanks again NHL. I failed to notice the digital specific designation. That makes the decision for me comparing the zooms. Now back to deliberating the zoom or the prime...

As far as the 15-30 or the 12-24, I was a little more interested in the faster glass of the 17-35 if I got a zoom.

Me too, It's the principal reason why I went for the 17-35 (f/2.8 & HSM) even though the 15-30 might be a better lens!

The 12-24mm is something else though: http://www.popphoto.com/assets/downl...gma12-24mm.pdf :-)

I for one will stick with my 17-35 and my 20f1.8. The reason I have rejected the 12-24 and the 15-30 is that I often use filters on my landscapes. It is just a factor that helped me make up my mind. The 12-24 has provisions for a rear gel filter but I own a bag full of others that I am comfortable with.

FYI The Sigma 15-30 comes with a lens cap threaded for filter -> You can actually mount a polarizer this way with the lens cap on in the front of APS-C based cameras... It will vignette on non-cropped full-frame though
