Is it good or bad?

Another bad experience was the Sigma 18-50 F2.8 (also long ago). It worked fine for half year and suddenly stopped auto focus for unknown reason (sure no drop). I sent it for service repair and the engineer told me the screws inside were loosen (by itself!!). Never encounter similar problem with Canon and Nikon lenses.

My sigma 17-35 went back 3 times before it was sharp enough .I didn't know at the time to check before you buy. And also sent back a sigma macro and had it replace with a much better sample.( it was it self repalced with a nikkor macro !)

their QC is a bit hit and miss.

The poll is a little one sided, regardless of the option.
You might want to re-think it.

I havn't had the opportunity to try a Sigma lens, but I'm not a brand fangirl. I've heard some awesome things about Sigma's new 35mm.

My one experience with Sigma put me off. We needed a 28-70 zoom for a Nikon, couldn't afford a Nikon so we tried a Sigma 28-70 f2.8. First copy was mush, took it back, second wasn't much better took it back third copy was a gem, we were happy, first shoot with the lens a light weight light stand with only a strobe head on it, no light modifiers falls and hits the lens severing it in half. Took it back it really was a bout a pound light head on a very light weight stand. The store agreed it had to be a manufacturing defect, so we get our forth lens. Not as good as the third but still a keeper. Four lenses four completely different qualities, not great QC.

Maybe I have been lucky, but every Sigma I have owned has been trouble free and nice performing. Now I have had problems with 3 Canon lenses....go figure.


6D, 5D, 7D, 50D, 40D, Xsi, PENTAX mx-1, Sony a6000, Sony a3000 too many lenses, flashes and aux. gear to list!:cool:

I believe Photosurgeon to be on some kind of crusade against Sigma. Just check his post history... Tons of comments against Sigma in random threads in the last 8h.


Canon 6D | S35mm f1.4 | 135mm f2 The rest: T3i, 20D, 15mm f2.8, 15-85mm, 24mm f2.8, 50mm f1.8, 85mm f1.8, 90mm f2.8 macro, 55-250mm.
So long and thanks for all the fish

The Sigma 35mm has got to be my favorite lens I've ever has the pleasure of shooting with. I also own their 85mm and previously owned their 50mm back when I shot with Nikon. I've never had any issues with any of these three lenses whatsoever; AF has always been reliable and and image quality the lenses produce is superb. Granted they all did require a bit of MA to get them tack sharp, but as did my Canon glass.

Now my Canon 50mm f/1.4 on the other hand has been a nightmare. First copy was way too soft wide open; exchanged it and got a decent copy. A little short of a year later the AF motor crapped out. Luckily it was still under warranty but it now just sits in my bag and hardly gets any use.

Genius! Imagine a Canon vs. Nikon thread where the options, if you had to use a Nikon for the day, would be:

A. Commit suicide
B. Tolerate

:lol:

My sigma 17-35 went back 3 times before it was sharp enough .

and in another thread you claim you have a problematic 17-70 that sigma would not honour warranty

you sure have a lot of sigma lenses after that ONE experience that put you off Sigma :wink:

BTW, just to get something helpful here, Helen has been running a serious survey about Siggy issue and working with Sigma to improve. Please visit her thread and send her your info. This is not a **** session but an opportunity to get one of our equipment suppliers some real data and possible improve their quality.

Most issues/complaints for third party lenses have to do with AF. Canikon have proprietary systems, so third party can only guess. On top of that, molehills become mountains for third party lenses, where OEM items don't get the same critique.
