I have been using Nikon for all my lenses. Recently found some SIGMAs with some pretty good specs.
Worth buying or not, SIGMA lens?

Should you write off Sigma entirely because they make cheap lenses? No. Should you buy a Sigma lense? Maybe, maybe not.

A lot of the time, Sigma lenses aren't so great - that's one of the reasons why they're cheap. But some of their lenses - DL and otherwise - have gotten quite good reviews. My advice would be to figure out what lenses look good and then look for reviews of those particular lenses. If you can, go to a camera store and try them out. If you can find a nice one, you'll probably save some cash, so it's worth doing the research.

Well, since you're using Nikon, this might not matter to you. But with the Sigmas, you need to be careful to actually try the lens before you buy them, if you can. From what I've read on the DPReview forums, the issue is that, at least with the Canons, Sigma figured out the interface by reverse-engineering, not by licensing the protocol. And apparently, whatever they use to handle that control isn't exactly foolproof. The result is a lot of bad copies around. Again, I don't know if this applies to Sigma's Nikon mount lenses, so don't take this as fact for your specific situation.

As such, check them first. The optics won't generally be as good as the OEM lenses, but for the price, you may be able to look past that.

Something to consider is to go to a photography store that rents lenses. See if the Sigma lens you are looking at is available and rent it for a few days. It'll save you money in the long run and give you some hands on experience with the lens to see if the cost/quality ratio is worth it.

Do a search on SIGMA lenses in your particular camera forum. There's a lot of reviews & comparisons made. Some SIGMAS are really good. Some aren't. There's a lot of 1st hand reviews & commentary on various lenses.

I had great success this Otakon 2005 with the Nikon "kit" ED 18-70mm... I really can't complain about it.

I do think I need to find something with similar specs in the f/2 variety though...

Most all of my Otakon 2005 gallery is with the 18-70mm lense.

same her with my 18-70mm f3.5/4.5
but then since i dont use 18mm often with people, and the 3.5-4.5 offers a little bit too big apprature, so im thinking of the simg 28-70mm f/2.8 or the 28-105 f/2.8-4

I have been drooling over the Nikkor 50mm 1.4 D lens for a while now. I'm not sure how good it would be for cosplay photography, but it does great for low light portraiture. I've currently got a 17mm - 55mm 3.5-5.6 DX kit lens, which does okay with plenty of light, but not so great indoors (I'm not a huge flash fan, so I try to do without when I can).

I have the 50mm f/1.8 and the crop is just a bit too tight for shooting at a crowded con...you have to back way up to get a decent sized crop.

As for portraits with it, it's just amazing!

I should also note that the 50mm f/1.8 is sharper than the f/1.4 at f/5-f/8, so you could save some $$ and just spend the $100 on the f/1.8.

indeed, i have also heard better comments on the f/1.8 rather than the f/1.4
but with the crop ratio on the D70s (maybe the D50 also), which is 1.5x, 50mm really becomes 75mm, which then becomes a pain to shoot in cons.
as for right now ill stick with the 18-70mm f/3.5-4.5, and will likely get a SIGMA 28-70mm f/2.8

Yeah, I only took about 2 shots @ Otakon this year with the 50mm...There just wasn't room to use it in the hallways.

I think I need to pick up a 35mm f/2.something and shoot with that...

I'm having the same problem with my 50mm/f1.8 on my 1.6x crop DSLR. Been shopping for a 35mm/f2 lens. So many choices. X-/

I was seriously looking at the 30mm/1.8 sigma lens, but it's just so expensive. Especially with the mixed reviews I was reading.

Like AcquaCow said, the http://www.dpreview.com forums. Just go to Canon SLR Lenses forum and do a search on "Sigma 30mm" or any lens you're considering.
