OK, these are quickly processed, nothing fancy, varying degree of crop, mild adjustments to exposure, contrast but NO sharpening. The fifth sample I used a Canon 1.4 TC III. The results weren't wonderful and this was one of the best.
I've done no set up/MA with the lens, just removed it from the box, strapped it on and walked out the door.

Honestly, on that 5th one, with an extender at that SS I don't think it looks that bad. I haven't tried it with an extender or slow Shutter Speeds yet.

Tonight was a mixed bag, some good, some not so good. Too late to post images but I will tomorrow. Out of curiosity, does Sigma's OS work the same way as Canon's IS?
Shooting with the 150-600 C tonight, the OS never seemed to settle the image in the viewfinder as effectively as Canon's IS. I tried both OS settings and I tried turning it off but it just seemed to me that the Canon variant has a reassuring 'lock' response in the viewfinder while the Sigma OS continued moving, though fluidly. The shots aren't wildly out of focus so it must be working, right?...Show more →
sounds like you need the sigma dock to activate the Dynamic OS. it makes the OS act rock solid in the viewfinder it looks so smooth and still its like its on a tripod

Ah! Is that the missing piece? Everything was obviously at factory default. Is using the Sigma Dock is the only way to alter this setting?

Gave the 1.4x (TC-1401) a try during lunch. Performance was terrible. The camera really struggled to gain focus most of the time. It just hunted back and forth. I got focus for a few shots but it was not sharp. This was fully extended to 600mm so was shooting at 840mm. Tried with C1 settings and with standard settings. It did work ok when the lens was pulled back a bit and I got focus quickly at 400mm (=560mm).
Light was very good and had clear skies and strong sun. Tried to focus on a close Starling and also a goose.
Not sure if I have a bad copy of converter or if it is just so hard to hold camera steady at 840mm that it could not get sharp focus cause I was moving. Guess I need to put it on a tripod to see if it works better with the tripod. That will be next test. Otherwise it will be going back to B&H to see if I got a bad copy.
Also I was pretty close to my subjects. Is it possible that I was too close? Does the MFD increase as well?...Show more →
You should not expect a lens that is not even f5.6 at the long end to AF well on any body when you slap a TC on it. The MFD gets worse with a TC.

Anyone else notice this from the Sigma owner's manual?
"Be sure to switch OS switch to OFF position before attaching or detaching the lens to the camera."
Is this for real? I can't recall ever turning IS off on any Canon lens when attaching/detaching...
I didnt read it either and I have not turned it off for mounting and unmounting. no issues as of yet but maybe I will for now on. Maybe they are worried if you tap the focus or shutter button it will engage and it stays engaged for like 2-3sec after released so maybe it could be bad if its still working and then disconnect its power

Possibly. I power down my camera before changing lenses though. Not sure what the concern is...

oh I have never shutoff a camera swapping. I would imagine if you shutoff the camera before removing then you would have no concern since no power is being sent to the lens. I dont know why they worry but my only guess is cutting power to the lens when the OS might still be spinning might cause some issues?

Received the 150-600 Contemporary today, and shot a bunch of test shots around the homestead. . When I opened box and removed lens I noticed 2 serious scuff marks on the barrel, also I did not experience what others have, which was it was not jittery in view finder when focusing.. Initial impression, I like the results from my test shots. Tomorrow if time permits, I will try to get some BIF in. However I am going to return it for another copy because of the scuffs. I'm wondering because of the scuffs, and it not being jittery, if someone else had it and returned it and changed the OS setting. All hand held and used 7D.

Joe, unless you were specifically testing the OS, I have no idea why you would use such low shutter speeds. I'm betting you would get sharper results with a minimum shutter speed of 1/500 even with IS on and a higher ISO.

Your absolutely wright Tony, but I wanted to see how sharp of a shot I could get with slow shutter speed, and how well the OS works. Normally I would not slow the shutter speed on any wildlife. Even still subjects move.
