I've had the above lens for just over a month and been very happy with it. Yesterday I noticed that when the VC kicks in the image in the VF jumps a bit to the left. I've not noticed it before, it's more pronounced at 70mm than at 24mm.
I know my friends one doesn't do it so I figure its faulty.
I also find it is effecting sharpness a lot of the time. Without VC on the lens is perfect but with it on its hit or miss.

I just thought I'd post this to see if anyone else has noticed this. I'm hoping to get it replaced although I need it over the next week so it won't be until later in the month. I can live with it for now.
 
Weird your friends doesnt do it, as the 70-300 VC also jumps a little when the VC kicks in and from what I understand its completely normal. Give Intro 2020 a call on Service Tel: 01628 799902 or email service@intro2020.co.uk and maybe they can help.

It might be that its normal to an extent, but this is quite a shift, and its a new thing as ive never noticed it before. To be honest its not that much of a big deal if the shots i was getting with VC on were turning out ok. Ive taken maybe close to 1000 shots with it since i got it but only now is there problems with the shots.
Its not as the motor kicks in, its as it settles.
I also tried it on my 60D last night and the lens seems very soft, to the point that id never really use it on that camera, which is a shame as it my only small zoom.
 
The Tamron 17-50mm VC does it as well. The stabilisation also takes slightly longer to kick in on the Tamron when compared to my Canon and Sigma lenses. If you don't wait those extra few moments before taking the shot (at low shutter speeds) it can give you a softer picture.

Thanks Mike. I would expect 3rd part systems it be a bit slower than Canon's but it definitely wasn't this bad when i first got it.

Maybe it needed breaking in lol.

This is the reason I've never bought a tamron VC. I knew about the problem where it takes a second to stabilize but when I tried it on my brothers lens I thought nono...not great for grab shots.

Sorry to hear you're not satisfied. You could always take it back if bought new...
 
Thanks Pill, i think you are half right, its broken lol.

If it had been like this from the start im sure i would have noticed it. I do leave a small gap between half pressing and taking the shot and its been fine until recently, now the gap is a lot longer, and its hit or miss if the shot is sharp. Without the VC on its fantastic, very sharp and accurate.
My mates one is older than mine and he uses it all the time yet hasn't got this problem.

EDIT: Ive just been reading a thread on dpreview about the VC affecting shots at certain shutter speeds. It was on a Nikon but the way the error is described it seems to fit what im seeing perfectly. It seems it might be early samples of this lens, although i doubt mine would be considered as early sample.

I assume this must be a fairly common problem. I was in the market for a 24-70 f/2.8 and after reading the reviews there seemed to be a few people mentioning the same problem so in the end I picked up the Nikon instead.
 
I cant say i saw any real negative posts about this lens before buying it but its surprising what you can find when you go looking for it.
Im still very happy with the lens, and the jumping doesnt bother me as much as the softness caused by the VC.
I look on it as i still get a good sharp 24-70 even if i don't use VC much. Its still smaller and lighter than the Canon 24-70 f/2.8 MKI, and thats important to me. I could never afford the MKII so that really doesn't leave much in the way of an alternative anyway. I tried the Sigma and that was very soft on 3 bodies so thats not an option.
