Looks like an old photographers vs. journalist(?) argument...
Perhaps that's a fair way to categorize my thoughts on photography - based more on journalism than creativity after the fact. To me, if I can't go and stand where you stood and see what you saw, it's not a photograph, it's something else. And there's nothing wrong with that - I'm not saying what people in this thread have is UGLY or undesirable, I'm just saying that they've crossed the line out of photography and into something else. Some rely so heavily on post processing to make something interesting that they should not call themselves photographers, but post processors. For me, photography is about capturing a moment. If you post process the bejeezus out of something, that moment is gone and something else has taken it's place. A fake moment, that never existed. And again, THAT'S OKAY - I'M NOT JUDGING THAT. I'm just saying that it's not really photography - it's a different form of art.
We have a few brick & mortar stores in Brisbane some will match genuine canon dealer pricing of online stores which i will buy from because i can take it with me and not wait for couriers
I bought a heap gear(1dx + 16-35L +more) a few weeks ago local Canon Dealer because they price matched all the items no problems(from another Canon Dealer in Sydney)
Then we have the other Brisbane store which has a online presence as well a bricks & mortar store who stick to the retail price and wont budge"quote from store manager we have the best price and we dont price match even from other Canon dealers"
Well my money was not spent in his store($9000.00 +) lost sale
Hmmm sounds decidedly odd. Do your other lenses work OK on your 7D?way outside return period,grey import[AUS],all other lenses,bar Sigma 150 F2.8 macro: 100 f2.8L IS,70-300 L IS,70-200 f4 L and Tokina 11-16 are sharp and crisp,the Siggy 150 is fine in manual and sometimes AF,doesn't display same degree of Doris,shall post so as to give you fine folks an idea of prob
The Sigma 120-400 is never going to be a match for good L glass such as the most obvious equivalent, the Canon 100-400L. But the Sigma is half the price. Even so, what you describe absolutely shouldn't be happening. If you bought it new I'd be looking at a refund or a fresh copy if you're still inside the 14 day DOA period.
I have the sigma120400 OS with 7d.similar front focus issues,have 70-300L which is a delight to use and extremely sharp will happily swap my Siggy for yours,lovely shots.
Mine front focusses by about 10 (which gives the soft look you described). After calibration is a lot better, but still slightly soft @ 5.6 but still very usable for up to A4 prints.
THis was at 5.6 http://www.flickr.com/photos/alexturton/7475200930/#
Gets very sharp at 7.1

The canon 100 400 is sharper @ 5.6. Both about the same by f8.
Because of the small max aperture I generally only use my sigma in good light.
