consider the very resolution hungry 50d behind your lens though, I agree it really isn't as sharp as some other lenses, but I wouldn't describe it as a soft lens - at least not on the 12mp sensor of the 450D

I have a question about the VC on the 18-270.

I tried it the other day and I noticed a "jerk" in the viewfinder everytime I pressed the shutter halfway to get a AF lock.
When I turned the VC off it did not jerk.

Now was this a normal thing for this sort of lens or was the modell I tried just defective?

I used it on my Canon 450D.
Appreciate all replyes :)

I've noticed the occasional jerk. If all else works ok I'd consider it normal quirk of the lens.

its normal. thats just the VC starting to work

I returned the lens today - reason being I just felt an urge for best possible IQ, larger aperture and quicker AF (so I got the bleeding expensive 17-55 f/2.8 as a replacement :oops: ). Still, anyone looking for a superzoom should really stop here, and prefer it over the 18-200 Canon or Sigma lenses! it's got some extra reach and a very very decent IQ considering its range.

:lol:

popo, it seems we got too used to our in-body IS. When i tried my friend's 18-270 (mounted on a nikon d80), i thought it was not mounted properly.
Anyway its indoor performance is too slow for my liking. It nails the focus but it takes a few tries to do so. I expected more from a lens which cost that much.

I think you're paying for a combination of the zoom range at decent quality and built in VC, not focus speed. Do Tamron even have a SSW/USM/etc equivalent? I have to admit it is quite a bit more than their 18-250 without VC which is the other similar choice for range.

Having used it a little more (poor weather still) I haven't noticed any of the suspected light issues I thought I had early on. I still think the zoom range is fantastic given its image quality. Not best of the best, but very decent considering. It does find itself on my 50D maybe 90% of the time for general use unless I'm birding.

Just thought some might be interested to hear. I just sent my sample of this lens to photozone for test so hopefully a review wont be far off :)

Why: I wanted a zoom to cover the shorter focal lengths, ideally starting around 16 to at least 80 preferably 100+ with IS. There isn't any great lens on Canon with that range. The 17-85 is closest but doesn't do it for me. The 18-270 happened to come out, it has IS, and in the limited info at the time seemed "ok" with the long range being a seriously handy extra.

How often? Not very, but mostly due to me having the CZ16-80 on Sony which still amazes me with its sharpness compared to general primes. So where I need short zoom I tend to use that. On the long end I tend to use the 100-400L.

But if I can only take one camera/lens and don't know what I'll need in advance, the 17-270 covers pretty much anything you can throw at it.

Good information on this interesting lens.
I've added this thread to the list of all Tamron lens-reviews here.

Having used the lens for a while now, I thought I'd throw some more observations in here. Not enough for a full review which I'll do some day after I finish one for the 100-400L...

Build

The zoom action was quite stiff when I got it, so much so it didn't need the zoom lock. It has loosened up and now it will extend by gravity if left dangling while walking. No other problems there.

Sometimes I get a lens error reported by the body. This has happened more than once, and only with this lens. I don't know if there might be a loose connection or maybe the lens firmware isn't quite perfect. But it is very rare, happening somewhere around 3 to 5 times since I got it. On each occasion I just turned off the camera, twist the lens out and back to force the contact to remake, and turn camera back on again. Then all is fine.

VC

Compared to other lenses I have used, this is the strongest stabilisation I've seen, although the only comparisons I have are my 100-400L and a borrowed 24-105L.

Optical quality

Sharpness is decent at 18mm end where I would compare it as similar or maybe even better than the Canon 17-40L. But I don't feel satisfied at the 270mm end where it always feels soft. I tend to use the wide end mostly for landscapes, in part as this is my only wide angle Canon fit lens. There is some distortion and CA but I don't find them a problem in practice.

When used for IR, it shows slight signs of a centre hotspot.

As the maximum magnification is at 270mm, "macro" shots by it also suffer from the softness.

Overall

I'm in a love hate relationship with this lens. If I had to pick one lens to go into the unknown, it will be this, but I know I'll be a little disappointed knowing I could do better at the long end.

You can't really get a lens that performs excellently over the entire zoom range, particularly when talking about a superzoom like this Tamron. For what it tries to do, I think Tamron has succeeded in creating a lens that has decent image quality with a very convenient zoom range.
