Sigma Lenses

[DznyDreamz]

First off, I am a total novice so please forgive my ignorant bliss!!!

Based on comments I have read on the board, I am assuming Sigma lenses are compatible with a Nikon? Is that correct? If so, are they less expensive then the Nikon line with acceptable quality? I need to pick up two new lenses as the ones I have are on loan. I'm planning to get a "fixed" 50mm for low light situations and a zoom of some sort. The one I have on loan is an 18-70 which I really like, but it doesn't do so good in low light!! If I can save a few dollars with a sigma lens, that would be fantastic!!

Appreciate any input you oh-so-knowlegable folks may have!

TIA

Just like every brand, Sigma makes some good and some bad lenses. You really need to do research on the specific lens you are considering.

The third party lens manufacturers--primary ones are Sigma, Tamron and Tokina--all make lenses that will work on Nikon dslr's. Generally they will offer the same lens with a variety of mounts, so you just need to be careful to purchase one made for Nikon cameras. Also, if you have a Nikon D40 you need to be aware that lenses without an internal focusing mechanism will not autofocus on your camera. I believe Sigma has designated its lenses with the focusing mechanism as "HSM"; not sure what the others call it.

Third party lenses tend to be much less expensive than comparable Nikon glass. For instance, I recently purchased a Tamron 28-75 f 2.8 for my D70 for less than $400. IIRC, the Nikon version runs in excess of $1200. Sigma also makes several lenses in the 18-55, 24-70 range that are f 2.8 throughout and get pretty decent reviews. Naturally the Nikon is a better quality lens, but I'm not sure it's that much better. At least that's what I'm telling myself because I'm just not in a position to spend that much on a lens at this point in time. Quality varies of course, but there are some very good third party lenses available. I've also surmised in reading reviews, etc. that quality control is somewhat lower with the third party manufacturers. I've read many reviews stating that the author's first copy of a lens was defective but that the manufacturer either repaired or replaced it with a much better one.

This is a good place to start for lens reviews: http://www.fredmiranda.com/reviews/

I like to compare lenses on Photodo.com - there are good, extensive reviews and a lot of different manufacturers!

Sigma is in general a good choice, but as stated by others, there are good and bad lenses (also by Nikon, Canon, Olympus etc).

Remember to ask for a Nikon compatible lens! Sigma makes lenses for Canon as well. Oh and check with the dealer for any issues regarding crop factors. Some lenses are designed for cameras with a crop factor (most newer dslr's), and if your camera is "full frame" (older analog, and some high-end dslr's), the lens will not work! - Just ask: will the lens work with my Nikon <insert model name>?

Hope it helps!

One of my favorite lenses I use with my Nikon is the Sigma 18-50mm f/2.8 EX. You will not be disappointed with this one.

As others have mentioned, research the specific lens you decide on. Another site which I check from time to time for information is http://www.kenrockwell.com. You kind of have to dig around his site but there is some really good information.

check out some of the tokina lenses as well, the 10-17 i got is built like a tank and rated really well...like everyone said, check the reviews for what ever lens...i use www.fredmiranda.com ( don't know if anyone mentioned there or not)

Thank you all for such great sound advice. It is incredibly overwhelming at times with so many choices, brands and price ranges! I will research the links you provided and try to wade through the information overload. Maybe I can give Santa a good tip and get just what I want wrapped under my tree!! Thanks again.
