Sigma 50mm f/1.4 EX DG HSM -SIGMALUX-

Nice quality to these. I've got my Sigma 50mm on its way. It seems that (optically speaking) it sits between Canon's 1.4 and 1.2 (and perhaps closer to the 1.2). I'll post some when I get it.

Great dog shots guys!! Gotta love the lens!!

Just make sure there's a Sigma repair depot near you. It will probably require calibration. Mine needed 2... but the effort was worth it.

I also own the 50L, and yes, the sig 50 is closer to the L. I prefer the 50L but not by much.

^ I hope my lens comes back looking like yours! Everything seems spot on. Great pics.

nice dogs.. but did you use the 50mm sigma on both this pictures? my exif viewer seems a bit off or I'm interpreting it wrong...

I read 85mm on the first

Probably just an honest sorting mistake!

prob he used the 85L mk2 on some of the shots.. thought my exif viewer is wrong..

Just curious ... Do you guys crop the pics you post here? because the 1.4 dof is very thin if your at 15 ft. but its hard to auto focus on that distance already...

Whoops, my bad! The IQ on both of these lenses are so similar that I often get confused.

Here are some more

Wow, excellent work^^^

nice.
how far are those taken? are these cropped? because here is a sample of my F2 dof is too thin unlike yours its at 1.4.
or is this about right?

HTTP response: NOT FOUND | MIME changed to 'text/html'

The images I posted are uncropped. I mainly use this lens on a full-frame camera, which gives it the illusion of 'more' bokeh.

It's my bread & butter lens... I have this lens on the Nikon mount as well.. where it's a little bit more accurate due to the multi-cam 3500FX af module

Here are a couple more snapshots from this wonderful lens... 1.4-1.6

how about your sharpening?

do the picture I posted above seem right to you in terms of DOF? also uncropped.

What do you mean exactly?

Use this http://www.dofmaster.c​om/dofjs.html

Are you wondering why the bottle is out of focus?

----
Sharpening is default in lightroom. When I export, I have sharpen for 'screen' set to minimal (for web) or 'glossy' set to standard (for print).

not wondering that th bottle is OOF but it seems you have more of the subject in focus at 1.4 compared to my f2!
update:

yes it is indeed more dof accd to DOF master..
Guess I know which body to buy on my next body upgrade!

OK, I "broke down" and went for the canon 1.4 -> sigmalux upgrade!

only shot with it so far:
