insane: I've owned several Sigma lenses and for me my Canon L lenses were always sharper, and as stated above created far smoother bokeh.

There is something to be said about Canon body's though, I found different lenses performed differently depending which body I used them on. My 70-200 f2.8L for example was sharp on a cheap 400D, not so sharp on a 40D, and then razor sharp on a 5Dmk2. Then my Canon 200mm F2.8 Prime was just awesome on any body - wish I hadn't sold it.

Just got back from a month in Europe and would have to take a guess and say 75% of the DSLRs I saw were Nikon's which surprised me a lot. Of the Canon's I did see they were typically 1D's or 5D's.


you can try process them all with raw with the same sharpness settings

also it could be that the 70-200 was like -5 in microfocus adjustment and the 400d/5d2 just so happen to be +4 inside the body while it's another -3 in the 40d, which end up with -8 and miss the focus quite badly



also if you have the budget and weight isn't an issue, always go prime due to the better f stop, sharpness and most importantly contrast and colour

That certainly sounds plausible, but honestly I've pretty must retired my camera kit. Just wasn't using it enough. Still have my 40d body and a 50mm f1.4 for TradeMe photos, but that's it now. My little Canon G12 and Galaxy S4 does the bulk of my shooting now. Sad I know.

I'd say it changes from lens to lens, Sigma makes some great lenses and some not so great ones.

not just different brands, some copy of the same lens are sharper than others
which is why some review sites like the-digital-picture literally has multiple copy of the same lens in their review IQ database, and some people orders like 3 of the same lens to test all of them and returns everything except the sharpest one

Could point out Sigma's new 50mm f1.4 stomps all over the competition.

Waiting for a new 85mm myself, also saving for the 120-300mm 2.8 Sport (about 2/3 of the way there).

It's not that hard to own the 50mm prime sharpness charts hence the 50 art's success here, every lens on the market with autofocus has issues. But sharpness on its own isn't the entire story.

Wow never heard of this lens ... might be what I need ... as long as it doesn't look and feel like a bazooka

Don't wait. The Canon 1.8 is the best out there. Fastest focus, track sharp wide open, buttery bokeh, light, can be had for loose change. No brainer!
