I've been trying to find out a bit more on the AF than "it seems as quick as the 35 L" and found this test;

http://www.lenstip.com/359.10-Lens_review-Sigma_A_35_mm_f_1.4_DG_HSM_Autofocus.html

It's not about finding focus fast on a still subject, it's how well it works with a "Case 6" AF-scenario and tracking.

And these samples, are they anywhere near sharpish at all? They look pretty useless to me.

http://www.lenstip.com/359.11-Lens_review-Sigma_A_35_mm_f_1.4_DG_HSM_Summary.html

And another thing, over at TDP it's stated that the 35 L is better in the corners @2.8, while everybody else seems to think it's MUCH better always. Why these inconsistencies?

Anyone who owns this care to comment?

Is photozone credible after their missed 24-70 II review.

This zoom is said the best ever made in its category in some reviews such as Dxomark. I trusted photozone.
I doubt.

In fairness to Photozone, is it not possible that sample variation had some part to play? From the review, it sounds like they only tested a single copy of the 24-70 II. Much has been said in this forum about variation between samples of the new 24-70, so I think it's a little unfair to make that conclusion. If somebody in this forum believes they have a stellar copy of the 24-70 II, why not send it to Photozone for a retest?!

dslrdummy

thanks for asking about Biff..... he was my closest wild animal friend
it has been a few weeks now....   I believe he is gone
------------
I had a lab retriever MIKE when I was a kid... he peed on the colonel's flowers across the street....living on-base.  So...we were told to get rid of him. My dad gave him to a rice farmer ...in the valley. I am sure Mike ran and swam his life away..
but
I never got over that event......over MIKE.  Never had another dog.
------------
Biff is right there behind Mike...in bonding...  I never saw a Jay other than Biff that would stand a foot or so from me...on the windowsill.. and just look at me...mumble little hellos...and listen to me play guitar..
he liked the maj7th chords..

it was a close friendship... of course he ate like a king
--------
same building.. yrs back....up on the top floor ..with a view...
we had an air cond unit that stuck out the window...
and had a plastic 'window' above it to finish sealing the weather out.
I would take out that plastic.. and the air con was then an open-air platform ....just below eye level...

I got a passing seagul to land there once... coaxing him with a bit of salmon..
then he came every day... of course...so I left the plastic out most of the time..
and  so 'Johnny' came by...landed on the air con platform ... and basically walked inside and cried out ..
each morning... he woke me up... like a rooster
his wife sat up on the roof facade... 10 feet up and they took turns...but he controlled it all
if I left the plastic in...he would tap tap tap on the window... and I would remove it...

Johnny took food from my hand...usually dog food pellets...sometimes fish ..
and like Biff..later..I would talk quietly to him..face to face... a foot away..
...usually about how handsome he was...but sometimes politics..

when we moved downstairs he circled for months .. and followed me to the market sometimes....I really missed him too.... but then Biff showed up down on the patio.
and the hummers too...

Biff's remaining wife and I believe his offspring ..hang out...but Biff was unique...

thanks for asking about Biff .....

Anyone who owns this care to comment?

For the corner sharpness i'd just look at the charts Roger at lensrentals has posted a few times with the sigma in the mix. I really like all the great reviewers out there, but somethings can really only be learned while tested in mass, and Roger gets it done better than anyone. He's in a unique position owning and testing hundreds of camera bodies and lenses on high end equipment. The sigma is the real deal.
 As for the AF tracking, i've had good results. that's hardly scientific but it's the best i can personally offer at this point. I've seen video reviews, i think it was posted here, comparing the sigma to the L. If i remember correctly, the reviewer thought that the canon was just a bit quicker. he also pointed out that the L has a much longer focus track, so it's a real feat that it's able to be as quick as it is. I don't think the reviewer commented on AF tracking ability.  that is annoying. I swear, on of these days i'll come up with some repeatable AF tracking test and post my results with my gear. Before you all say how they wouldn't hold true under all circumstances, i know. perfection is the enemy of good.
