Hey s8n - I can't believe you haven't mentioned the BOKEH this lens produces! It's smoooooth as. Here's some pics I took at f2.8:

That's one amazing lens right there

Doesn't look that sharp? Looks over-compressed and over-sharpened.

Perhaps you'd like to demonstrate some of your sharp images?

Bokeh above is stunning

If you want to see some pics of the 135 at F2 at a veriety of ISO settings, then have a look at an old thread of mine where all the telephoto stuff is shot with the 135 here.

Well, if we're going to compare my photos to the above - then naturally to make it a fair fight, I'd have to use a 5D eh? More resolution and a weaker AA filter = sharper photo. Bokeh is wonderful - but I can live with slightly different bokeh - can be interesting at times (mirror lenses anyone?)

http://danielgphoto.com/misc/_MG_3725.jpg <- Sigma 105 f/2.8 @ f/2.8. Close to no sharpening added. Sharp enough? $400.

http://www.danielgphoto.com/misc/crop3.jpg <- Sigma 100-300 f/4 @ f/4. No sharpening added.

$1129. Sure, it's 2 stops slower, but I don't shoot low-light, so it's irrelevant. I'll admit openly that it's bokeh is ugly at times - but it looks interesting.

Sharpness is a over-rated anyway. It should only become a consideration if you're planning to print large (16x24"+). At any sizes smaller it just becomes completely pointless.

We can leave it there - or continue pointlessly.

Just a end note - I nearly bought a 135 f/2.0L last year - for $860, but alas - I realised that I didn't need it and buying it just because it was L wasn't going to make my pics any better.

I wouldnt waste my time with Sigma again, there lenses have the WORST quality control ever. 10-22, 24-70 f2.8, all were terrible, slow focusing, hunted, soft in corners yada yada..

Sucks to be you eh? I must be lucky.

Not at all

I love my L glass and was lucky to sell the Sigma stuff at the price I paid! On a 5D, you'd be nuts to run anything other than L glass.

Not saying the Sigma is junk, but they have quite a few issues (24-70 notorious for having a yellow cast and noisy as one example, 70-200 f2.8 only really sharp from F4 onwards unlike the L)

Just cause you had a bad run with a few (you hardly tried many if it was just the 10-22 and the 24-70) it doesn't mean they are all bad. There are some very highly rated Sigma lenses which many people are very happy with.

I have a 5D and a Sigma 100-300 f/4 and I think the optical performance of the lens is excellent considering the cost of the lens. And yes I have L glass to make general comparisons with...

Saying you'd be nuts to use anything other than L glass on a 5D is just like saying you'd be nuts to write off a whole company because you had a bad experience with two lenses.

Oli, you must have obviously misread what I said, I never said ALL sigma was junk. But they have alot of QA issues, spend some time on dpreview, fred miranda and you'll see. 2 outta 2 lenses for me, thats bad imo. Why would I want to try more Sigma lenses?

I don't see many 5D shooters with Sigma - I guess you get what you pay for.

Sigma does seem to be great for the budget buyers, but I still am of the opinion after trying their lenses that if you want quality and reliability L is the winner by a CLEAR long shot.

Disgree all you want but you just need to look at the facts.

You're right Oli, I might add a photo a day just so people have something to look at. Be warned, it may not be too pretty.

new thread sounds great

perhaps a L vs Sigma debate - as useful as a Holden Vs Ford :P

How would the 100mm f/2 USM stack up against this lens?

Both f/2..only difference would be the length..(or not)?
