How many aperture blades does this have? Why would someone buy this over Sigma 50mm 1.4 if Sigma costs $349?

Why would someone compare a 50mm to a 35mm? Its not even the same focal length..

I suppose it has nothing to do with the cameras and all to do with that particular lens. For the price of the 50mm 1.4G plus it being a prime lens I figured it would focus super quick. It's funny that you bring up the 35mm 2.0 D lens having problems. I own that lens also and mine focuses just fine and much faster than the 50mm 1.4G. I'd love to hear what you find out from Nikon about this problem.

First, it's not a Nikon. There is a chance that it may not fully functional properly on future Nikon models. The new Sigma ART series can have firmware updated after release, this could solve the problem. Secondly, I have had slight out of focus problems. But this might not the problem of the lens: the camera has to detect the focus difference and send a signal to the lens. If the camera fails to detect the difference at a particular point, it will not send any signal to the lens. And you will have a focus problem for that shot. Therefore, the problem might not relate to the lens after all. Overall I have 99% positive experience. As for the rest of 1%, I would argue that's is true for any lens you purchase, even for a $1,500 Nikon lens.

I agree with the previous comment. The Tamron lens is a good 'general' lens for your bag. The kit lens is worthless in my opinion and should be avoided at all cost. Your 50mm 1.4 is my recommendation.

For the D50 and D90 I'm partial to the 28-200. Got three from Tamron and one from Sigma and all were under $100 on Ebay. They AF quickly and are razorsharp. Most were bought attached to a cheapo camera like an N60 or a N2020.

At Photokina 2012, Sigma announced a reorganization of its lens lineup into three categories - 'Contemporary' covering lightweight, flexible zooms, 'Sports' for larger telephoto lenses, and 'Art' for a wide range of optics aimed at serious photographers, including ultra-wideangles, macros and fast primes. At the same time the company announced three new lenses, one in each class, with the 35mm F1.4 DG HSM as the first release in the Art category. It's designed as a high-quality alternative to the camera manufacturers' equivalents at a substantially lower cost; even at its ca. 800 / $900 launch price, it's a tempting proposition compared to Canon, Nikon and Sony's offerings, which all sell for upwards of 1000 / $1300.

TVM,Thanks for the heads-up on the Sigma. A popular photo mag just this month had a review on a Sigma lens - 18mm/250mm. They gave it a big thumbs up so I'll keep checking up on Sigma for quality and suitability/cost-effectiveness for the T1i. I'll already start some reading up on the 150mm/500mm. BTW - that "500" # sounds juicy. Per Tech's comment (and I educated myself more on what he was talking about) what with a 1.4 or 1.6 mag ratio that 500mm max zoom should be more like in the 700's. I guess that means a quality tripod (read "triple digits") is in the cards too. TVM,Thanks for the heads-up on the Sigma.

J. ONeill says: Did you make a decision? I am currently debating the same two lenses. I am leaning towards the Canon since it seems there are quite a few quality/AF issues with the Sigma. Any advice is appreciated. If you own a camera with micro focus adjustment like the 50D or 7D, Sigmas front or back focusing is a non-issue. Also, even if you don't own a camera with micro focus adjustment, if you get a Sigma lens that front or back focuses, you can send it to Sigma for calibration.

I love my 35 but my 50mm 1.4 was what I started with and I still love it.:)

Thank you for taking the time to answer my question, I ended up buying the Sigma lens and I agree with you when you say that is a great value for the price.So far I'm very happy with this lens, I have used it in both daylight and night time (with external flash) and the results have been excellent with my D5000, the OS is great and focusing is very fast indeed.Again, thank's !George

If your are deciding between a 35mm and this lens.. I would ask.. What do you plan to shoot? If you need a wide lens for landscapes I suggest the 18 - 50... If you are looking for a portrait or low fstop fixed lense for close ups I say go with the 1.8 35mm. If your asking Nikon versus sigma.. I would say you get what you pay for. As far as the sigma performance... I use the lense quite often. I shoot in low light bars and venues and the lens is covered in beer..The lens is great for low light shooting at 18mm. I usually switch to a 50mm if I need a closer shot.

I owned the 50D and now own a 7D. I have had my 17-55 f/1.8 IS for over 2 years. I bought the 24-105 a year ago to replace my 17-55 hahaha yea let me say right now I am not selling my 17-55 and when shooting indoors the 17-55 f/2.8 is will be my first choice over the 24-105 f/4 IS. Indoors f/4 is slow period. I ended up buying a Sigma 30mm f/1.4 to shoot indoors for low light and I LOVE it. Anyways on a crop body I would pick the 17-55 f/2.8 IS over the 24-105 f/4 IS for indoors unless its a really well lit room or I am using my 580 EXII. I am leaning to primes anymore and would recommend the 17-55 f/2.8 for you. Another option is Sigma 30 f/1.4 and the Canon 85 f/1.8 and you spend less then either of those lenses heck you can throw in a 50 f/1.8 and have 3 lenses for the price of 1 if you don't mind switching lenses.

I have both lenses and the real question is how close can you get? Both lenses are great, the Nikon is a little sharper and will focus a little faster on my 5200, but the reach of the Sigma is really nice. another option is the new Tamron 150 to 600 when you can get it with the Nikon mount. So if you can get close the Nikon, if you need more reach the Sigma or the Tamron!

Hi Joe, I think this IS a Sigma product when examing the packaging. And the quality is excellent, fits my 150-500mm zoom perfectly. I would haveno hhesitation in buying another. Just don't forget the import charges those add another 20% to the price. Over all a nice bit of kit.

I'm so glad there's something posted here - this is one of the lenses I'm considering getting my husband for Christmas. He has the Sigma 50-200mm lens right now and in my experience with it, it hasn't been too bad. Should he be happy with the 18-200?

Thank you guys, really appreciate you help. I was in confused state in selecting sigma 50-150mm f/2.8 or tamron 70-200mm f/2.8 macro, but after a week study i have selected this sigma 50-150mm which is exactly in my budget. Once again thank you guys.

I am very happy with this lens. I have not tried the Sigma. I have the tamron 28-75 and the 70-200 VC both outstanding lenses - fast and sharp. Tamron is slightly more expensive and reviews always slightly higher. Sorry I could not give you more info about the Sigma
