onegreatcity Offline • • • Upload & Sell: On p.1 #1 · Sigma 20mm 2.8 lens?? Does anyone own or know anything about a 20mm 2.8 lens by Sigma? I know there's a f1.8 out there but someone is selling a 2.8 locally and I can't find anything about it... Thanks! Jan 18, 2012 at 12:04 AM

trenchmonkey Offline • • • • • • • Upload & Sell: On p.1 #2 · Sigma 20mm 2.8 lens?? Sure it's not a 20-40 f2.8 Don't think Sigma made a 20 prime other than the 1.8 version. Jan 18, 2012 at 12:08 AM

Seller swears it's a 2.8, Canon mount, 20mm prime. I'm sufficiently confused and intrigued that I'm going to go see for myself. Maybe he's confused and it is the 1.8. He says he bought it new locally about a year ago... Jan 18, 2012 at 12:29 AM

onegreatcity Offline • • • Upload & Sell: On p.1 #5 · Sigma 20mm 2.8 lens?? Well, as suspected, it was the 1.8 lens and at a very fair price, basically BNIB, one year old and only used for a handful of shots. Despite the mixed reviews, test shots on my 7D so far are very pleasing, and though AF is a bit noisy, it's also accurate and relatively quick. I haven't downloaded any shots yet but shooting wide open looks promising too. According to Sigma, the minimum focusing distance is less than 8". Hmmm...is this a sleeper? Guess I'll find out as I bought the damn thing! Tomorrow, I might take it to work and try on the 5Dii to see how it fares. Thanks for the input trenchmonkey and Ian D! -Cam Jan 18, 2012 at 02:51 AM

leftymgp Offline • • Upload & Sell: Off p.1 #6 · Sigma 20mm 2.8 lens?? Please report back on your findings with this lens. I have been toying with the idea of buying one of the wider sigma primes. Jan 18, 2012 at 04:07 AM

martsmith42 Offline • • Upload & Sell: Off p.1 #7 · Sigma 20mm 2.8 lens?? I've had this lens for 7 years and find that my copy is excellent, even wide open. One aspect I like is the very close focussing abilty, combined with a wide ange on my 5d. Really interesting results. Jan 18, 2012 at 12:06 PM

Snopchenko Offline • • • Upload & Sell: Off p.1 #8 · Sigma 20mm 2.8 lens?? Bryan Carnathan wasn't as lucky... even though the FL/max. aperture combination sure looks tempting on paper. http://www.the-digital-picture.com/Reviews/Sigma-20mm-f-1.8-EX-DG-Lens-Review.aspx Looks like it has a "classic" sharpness profile: quite soft all over wide open and only improving gradually. Probably has its uses though but a good candidate for Sigma to update. Jan 19, 2012 at 08:21 AM

Lars Johnsson Online • • • • • • • Upload & Sell: Off p.1 #9 · Sigma 20mm 2.8 lens?? I have owned two copies of the Sigma 20/1,8 lens. For it's price it's a rather decent lens. A little bit soft wide open but otherwise it's an ok lens. And you can't find another lens that fast and with that price Jan 19, 2012 at 01:27 PM

Snopchenko Offline • • • Upload & Sell: Off p.1 #10 · Sigma 20mm 2.8 lens?? No, of course, but as a 16-35 II owner I don't find any of the 2x/1.8 Sigmas compelling. Jan 19, 2012 at 02:54 PM

markshelby Offline • • Upload & Sell: Off p.1 #12 · Sigma 20mm 2.8 lens?? Amen to the "can't find anything else like it at the price", that sums up my feelings exactly. The very close focusing makes for some nice shots too. Jan 19, 2012 at 07:35 PM

I wish I could have any of the lenses for my own fun but that time has passed. Besides, the AF is probably stone age - I've had my fill of screwdrivers and buzzy motors, thanks. Maybe Carnathan had a poor sample but his results (seen in the standard tests) are alarmingly soft. I remember having something that was as soft - a KM 18-70 kit lens that showed something similar at one setting - and I'm glad I gave it away. If only Sigma had updated it instead of releasing half-arsed lenses for mirrorless and ultra-expensive cameras that nobody is going to buy... fast wides are all the rage now, they're stupid not to get onto this bandwagon.

But the photo's wide open or close to wide open is not unusable. Have you used or owned the lens? I have owned two copies and none of those where unusable. And I used the lens for five years Jan 20, 2012 at 12:51 AM

Lars Johnsson Online • • • • • • • Upload & Sell: Off p.1 #15 · Sigma 20mm 2.8 lens?? This is the only photo I have uploaded from this lens, because it's a rather long time since I owned it. Canon 10D + Sigma 20/1,8 Jan 20, 2012 at 12:58 AM

As reported before the 24 f/1.8 photos are far from unusable wide open and in fact are quite sharp. You haven't even tried one 20/24/28 I bet but always discredit them. Show me a 20/24 this fast, and this cheap with the same IQ. Jan 20, 2012 at 01:10 AM

onegreatcity Offline • • • Upload & Sell: On p.1 #17 · Sigma 20mm 2.8 lens?? I've had limited time to play with this lens but I will try to find some time later tonight to post a couple of test shots. Early indications are what you'd expect, decent centre sharpness wide open and improvements across the frame stopped down but I should qualify everything by saying I'm NOT a pixel peeper kinda guy and generally enjoy a shallow DOF so I enjoy the results wide open or close to it. I did have a chance to test this on a 5Dii at work and again, decent results. I'll check the card in my 7D but I'm pretty sure I have some comparison shots taken with the Sigma and a Canon 16-35 II at 20mm. If I can find 'em, I will post 'em. Glad the debate is friendly, lol! I also just realized that this might be the worst or most inaccurate title for a thread ever as there is/was no such thing as a Sigma 20mm 2.8! Stay tuned... -Cam Jan 20, 2012 at 03:27 AM

I'm really itching to give this a try sometime but they're difficult to find and I don't want to buy blind without using this lens for a while - especially since I imagine it'd be pretty difficult to get rid of it if it turns out to be substandard. Nobody I know has any of these lenses unfortunately. Jan 20, 2012 at 01:44 PM

onegreatcity Offline • • • Upload & Sell: On p.1 #19 · Sigma 20mm 2.8 lens?? OK, I'm throwing these up very quickly but, aside from some distortion on the edges (most notable in the lower left) that I attribute to my angle, distance to the cabinet and inherent nature of the wide angle, I'm not unhappy. This is one (really bad) photo quickly taken using a 5Dii and the Sigma 20mm 1.8. Under that is a substantial crop from a drawer on the upper left side. Aside from a conversion to jpeg and sizing for the web, no changes have been made. ISO 400, f/8, 1/15th Thoughts? Jan 20, 2012 at 05:50 PM
