Sigma 20mm 1.8 at DVinfo.net

Anyone using this lens with a cropped sensor for steadicam work? If so, how do you like it?

Mark Von Lanken · June 13th, 2011, 06:58 PM

I'm not a moderator, but just a heads up...this post really belongs in one of the DSLR sections. It will probably be moved. Now to your question.

I like the Sigma 20mm 1.8 so much that after I used one at the reception I bought a second one. I shoot with Canon 60d's and it's great for handheld or glidecam, especially when it's too dark for the Tokina 11-16 2.8. It doesn't give the big wow look of the 11-16, but when shooting in low light, 1.8 blows away 2.8.

Of all the lenses in my bag (8) I feel like I got the most for my money with this lens.

I completely agree with both Mark and Craig - and I'd also like to add that the close focusing comes in very handy for detail shots. I think the distance from the sensor plane it can focus is only 7". And reviews will say its soft, but I'm very happy with the sharpness.

Hi Craig,

Your post peaked my intrest. I got out the Sigma 20 1.8 and Tokina 11-16 2.8. They looked the same brightness at 2.8, but then when I took the Sigma to 1.8 it was noticeably brighter, as it should. Are you sure you had both cameras at 2.8?

Hi Joel,

I had always been impressed with the close focus abilities of the Sigma 20 1.8 as well. On my Panny HMC150 I always used the macro abilities of the lens and greatly missed it when going over to DSLR. A lot my lenses will not focus closer than 2-3 feet. For true macro I have a vintage Vivitar Series 1 28-105 that will focus at about an inch or so, but I don't use that lens too often, except for macro purposes.

I just compared the close focus capabilities of the Sigma 20 1.8 compared to the Tamron 17-50 2.8. The Sigma allowed me to get much closer, but with the Tamron at 50mm, I was able to get the exact same framing in focus. Now for moving shots, it's much easier to use the Sigma 20, but for a static shot, I was impressed that the Tamron could get the same shot when framed at 50mm.

After re-testing this, I think my error was using the Tokina lens with a more contrasty profile. Of course I should use identical profiles! My mistake.

As food for thought, I'd like to toss in that while not as wide as the 20mm, I am very fond of my Sigma 30mm F/1.4. For reception work it is excellent. It is an odd angled lens, and a bit soft, as Sigmas tend to be, but nevertheless it's very useful.

I shoot with this lens on a glydecam all the time. The focus can be soft, but at least it's bright enough to see.

When I was using DLSR's the 20mm was my favorite lens for lowlight work. Awesome lens for that purpose! Used it on a glidecam to and it was great. Very enjoyable. Since moving to the AF100 with it's 2X crop factor I don't use this lens on the glidecam but I use it for all the dancing and wow is it sharp! Always running F1.8 ISO 1250 and 1/60 shutter. Very happy with it. When taking stills it's not a sharp lens at 1.8-3.5 apertures. Once you hit F4 it's wonderfully sharp.

Jeremy White · June 19th, 2011, 11:21 PM

Hmmm...I'll try it at 4 to see the difference...

I'm going to try the Sigma 20mm 1.8 (NIKON version) first on a Merlin/FS100 setup . I'm really happy with a Tokina 11-16/Canon 60D/Merlin setup--I never (I least I dont) adjust the focus, and everything is in focus front to back (reasonably so), so have to deal only with exposure (via aperture ring or variable ND filter).
