The Sigma 20mm is a gem of an aquarium lens, but the bokeh can get a little jittery at times. It's MFD for a 20mm is very good, and it makes the perfect aquarium lens for me on a 1.6x body. Nearly all of the shots here in my Marine Life gallery were taken with the Sigma and 20D combo.
Here's #5 @ f2.2 for ulrikft!
P.S. RustyBug: Yeah--long story on my E46 M3, but it got totaled by some idiot who drove into me two years ago at a red light.
My pleasure; you made me dare to crank everything up enough. I'm quite happy with my JPG:s now, but WB and metering keeps f*cking things up. So I continue to shoot JPG + RAW.
Back to business! Sorry for the flooding with shots from this lens, but it really deserves attention.
I think the last one is quite "3D", and it is a JPG straight out of the camera. This medium distance also often make lenses act like crap, but the Samyang is just nice and smooth.
but you saved my face
