[img] Sigma 30mm ~ first impressions. bokeh :)
Mar 18, 2006

http://www.rytterfalk.com/2006/03/17/sigma-30mm-14-first-impressions/

And additional images and info, just for you!

All images taken at close to wide open. 1.4 - 2.0 (most common has been 1.6 for some reason) and Adobe lightroom as processing tool. No sharpening applied in Lightroom, only standard stuff in Photoshop.

I've taken hundreds of images and I must say that a big amount (bigger than normal) is keepers. I really do love to work at 50mm it suits me very very well. And for protraits it's a fantastic lens. you get close enough. Almost like a macro.

I'll put up some fullsize on my flickr later, right now flikr from China is SOOOOOOOOOO slow.

Hi Carl,

You just caused a bad case of lens lust here. Bummer.

Bokeh really seems nice, is the lens prone to flare? How about colour - the colours in your pictures looked very good to me, did you have to tweak them a lot?

Cheers,

-Topi Kuusinen, Finland

I'm using Lightroom and tweaking is kind of a natural part of the lightroom workflow. But, I haven't done much. Easy to fix and have fun with sliders!

Hi Carl,

nice snapshots, with bolt colors. You say that most of the pictures are keepers. Can you say something how the autofocus works at far distances (infinity)?

good luck, Paul

I'm working on it. Will give more specific info as soon as I've taken enough photos. My style of shots are at pretty close range.

But I have a feeling that auto focus on SD10 isn't good enough for this lens.

Nice work Carl

I appreciate to have some info too.
Did you have a split screen installed in your Sigma?
Or was MF? Also if sharpness neat the edges is acceptable.
Some said that edge sharpness isn’t the best with that prime.

I also have 28mm and plan to get the 30 for low light indoor or fast street photography.

Thank you.

First, it's auto focus on those pictures. I do use MF sometimes and it's a lot more comfortable then the 50mm EX.

Second, I will take some near the edges portraits so that you can see some real world photos. I'm sure this one is very good for street photography. Can't think of any reason why not.

And when the new sigma comes, this lens will probably get more useful. (AF etc)

Looks pretty impressive. Especially the OOF parts look very pleasing. Did you use AF or MF on these shots?

I used auto focus. I always turn the focus ring to max off, and then let auto focus get into shape again. That way I get good result most of the time. This is what I do with all lenses if I wanna use AF.

I used my girl friend a lot today. And I will go home soon to process the result. So a little later, maybe another five to six hours before anything online. (or maybe tomorrow)

very pleased with the 30EX
In reply to Rytterfalk, Mar 18, 2006

I'm very, very pleased with this lense. It's my best lense investment.

It gives me the opportunity to shoot indoors without flash. And that is very convenient because it doesn't flattenout everything so much. (esp. de pics of my baby-son)

Most OOF is due to usererrors: the shallow DOF requires very precise aiming at the subject, which is not that easy to achieve. To be sure i take extra shots when it looks tricky. But most of the time all al spot-on.

I'have to admit though that occasionally i don't understand the OOF of some pics. (allthough sometime i was too close to the subject or the very fast HSM was still re-focussing while i thought it had locked in allrready). Sometimes (1%) nothing seems to be in focus.

I think it is sharp to very sharp. It is a little soft wideopen and it has some fringing, but these chracteristics also give it a nice blur which is pleasing for skin and sometime give a fantastic bokeh to non-humoan subjects.

(I know these comments like "nice blur" are sometimes a 'translation' for "heavy distortions" but with this 30EX it is not the case because at other F/stops the lense is razorsharp.)

I use it for portrait and street-photography (mid-range). Since is think it was designed for that I don't expect miracles for landscape/infinity (allthough i'have seen very good samples here) My latest (2nd hand) purchase: the 50EX DG will probably do better in that respect.

I found soft corners in many of my shots and suspect some softness in a stitched pano is due to soft corners. Other than that, the lens is superb and I find the AF to be better on this lenses than many others (although I have never really compared them).

What does everyone think of edge quality here (f13)

Well it's not perfectly sharp anywhere all around. I'll see if that's the case with mine or if it's less at different stops.

Given the f-stop and shutter speed (even though it was on a tripod), and the distance to the subject, and the composition of the subject, I am not sure if it could be any sharper. But I will most likely be back there in three weeks or so and will re-shoot it. I have similar shots with the 15 and 50 and much to my chagrin, th 50 isn't as sharp as either of the two.
