Very cool, I recognise this. I take it you work there.

I guess the username was kindof a clue, too...

figured it out, nevermind.

Actually, I don't think more should be in focus at F3.2. It's a pretty large aperture still, leaving you with shallow DoF. The shot 'might' be slightly front focused, but not too severely. Imho.

how close were you? at 2 feet away you're DOF is less than 2 inches @ those settings. The brim of the hat is 2-3 inches deep, so it could be that you either miss focused or the lens is front focusing.

My lens was ok when I got it new but after a year of use I had to get calibrated. it doesn't take much to knock them out of alignment. and at wide apertures at close distances it can be really noticable.

Great shots everyone... think this will be replacing my 50mm 1.8!

I was proabably about 4-5 feet from him and on all of the other shots, he'd have like one eye in focus and the other not even though his eyes are almost on the same focal plane. that doesn't look like oof from shallow dof to me, it looks like iso-ish grain... so how do I go about finding out if it's the sensor or the lens?


and by "not front focusing too bad" how does that translate into good portraits? I can't get a good shot to save my life anymore

would anyone like more examples? I'm quite new to this and don't have another lens to slap on the camera to see if it's def the sigma.

Oh I figured it out guys.. user error!

Amazing shot! You must be warming up to your Sigma a little more. Mind sharing how you lit this photo?

Thanks! I'm liking it more and more. Still has a ways to go to catch up to my 85mm.

For this shot I was standing about 6 inches past the other end of the pool table. I had an Alien Bee B800 set to 1/4 power with a 42" umbrella pointed at my neice to the right of me. On the left side of the pool table about half way down was a Canon 430EX Speedlight with a small 32" umbrella. Both were triggered with Cybersyncs. BTW...this was my first time using this setup so there was a lot of trial and error to get this shot. My neice was very patient, thankfully.

This thread is full of awsome photos, from closeups to portraits to landscape!

I've BARELY used my 85mm.. it's just so long but i hate to sell it because it's my only low light telephoto lens. I've had the nifty before but it never really clicked with me. I think this may be a really useful prime lens for me!

Did you use a ND filter? What aperture was this shot at? I cannot see exif. Awesome shot btw, it's nice when you can mix off camera lighting with wide apertures!!

My Sigma arrived today!! The focus was slightly off but microadjust fixed that! That's the least of my worries at the moment because the shutter button is becoming unresponsive so it may have to head to a repair center.

Anyway, here are a couple pictures from it:
1/250 F2.0 ISO100 One is the full pic and the other is a 100% crop

There's a pretty easy fix for that. Here's my postregarding the problem, and the video tutorial.
