how's the AF is it really slow like what the review said?
I don't have the old Tamron 17-50, but i do have the tamron 28-75.
So yes, if I compare the tamron 28-75 to this new 17-50/2.8 version II with built in motor, the AF is slower. But i have also played with the sigma 18-50 2.8 briefly and i'd that is slower than the tamron 28-75.
If you ask me, both the sigma 18-50 and tamron 17-50 with built in motor are of the same speed from memory, very roughly. If you say from turn to turn of coz the difference is significant. But from experience in real life, that difference usually is padded down by pre-focusing and the way you shoot. For eg, i have a 30mm f1.4 and trust me below f2 and 3m distance you would not want to mess with anything without pre-focusing and shooting anything without good contrast.
That said, i have used the tamron 28-75 for about 100 weddings and though fast, the slight misfocused pix number about 10-20% for each wedding. (ie moderate to low light). In fact this made me change my shooting style by changing to 30/1.4 and 12-24/4.
From my brief usage last night on the exact same body (just a D70) with about 300 test shots, it seems that the focusing accuracy is pretty good....there is still hunting since the light source is only a 40W florescent light in my living room, but the accuracy is good with regular objects more than 1m away at f2.8.
If i measurebate with less than 50cm away and f2.8, there is perhaps slight front focusing for about 30-50% of the shots but that can't be helped since without calibration you'll also get this with Nikon lenses. (anyway i do MF for my macro shots as the parallex error with focusing with the sensitive centre AF point and moving later is quite great, and the side AF points are not that sensitive under low light and with shots like the ring, I shoot with D70/D200 only).
For just 500 over bucks, good usability wide open and good 17-50 range, cannot hiam lar.
My prime 30/1.4 is not that sharp wide open neither but definitely usable up to S8R.Actually i am selling the lens asap this few days as my wife secretly bought it for me behind my back while shopping in HK (i wasn't that interested, too many lenses and not keen to lose any of them to pickpockets in weddings - yes it happens!). I've put up an ad in B/S, but if nobody wants i'll use it for 2 weddings this Sat and Sunday and report back more for real life usage. My view is that there is a difference between measurbating and shooting real objects and one needs to distinguish that.

Thanks for the initial comments. Just to check, the Sigma lens that you were referring to - was it the new HSM version, or the normal screwdriver type?
I would like an opinion on the focus speed of the new "af-s" tamron vs the 18-70 dx nikon. I thought that was a good lens with focus speed. But the nikon 18-55 (even the latest vr) version is too slow focusing for my liking. So is the tamron more like the 18-55 or the 18-70, if its like the 18-70 then its fast enuf for me and will seriously warrant my consideration!

I used to use the older 18-55 without the VR and u're right, it isnt fast at all for an AFS lens.
I'd say the first gen version of the tamron should be comparable to the older 18-55. So since the AFS version of the tamron is slower than the first gen version, and assuming nikon didn't make the 18-55 faster for the VR version, I'd hazard a guess that the AFS tamron will be slightly slower than the 18-55 VR. Never tried the 18-70 before so can't comment how fast that is compared to the rest.
hi i'm quite newbie in DSLR and want to buy the latest canon 450D as my first DSLR, anyway,
since i got a spare cash and i mostly shoot indoor , handheld, without flash, i'm thinking to "upgrade" the kit lense to this tamron instead (actually i want the canon 17-55, f.2.8 but it's too expensive and to heavy and to big to be carried casually)
i got some question, since i shoot mainly indoor without flash and handheld,
will i benefit more from Canon 18-55mm IS (kit lens)
or
this tamron 17-50mm f2.8 ?
i mean how would it compare the IS on the canon vs the constant aperture of f/2.8 of the tamron ?
and lastly how to check wheter i get a good copy or not?
any tips on how to test it on the shop?
cause in my country, i don't think they accept refund
thank you very much.

Not that I know of.
Got mine from Yodobashi Camera yesterday for 42000 JPY (not including the 13% rebate on the next purchase), plus a 67mm UV filter. I can't compare it to the older one I don't own, so all of this really applies to the 18-55 that it replaces.
First it's really heavy. Like twice as heavy as the 18-55. The box says 440g, that's almost as much as the D40 itself. Throw in the filter and the hood and it's probably just as much in fact.
It feels really solid, the rings are smooth and precise (there's a world between the focusing rings of the 18-55 and that of the 17-50), and the lense only extends as you zoom in. Somehow, if the labels were exchanged, I'd have no trouble believing the 18-55 is a cheap third-party lens and the tamron the expensive Nikkor equivalent. There's an AF/MF switch and a lock switch that prevents zooming. Since the zoom is fairly stiff, it's really useless (I can't imagine the lense creeping in or out). The mount is made out of metal.
The range is pretty much the same as the one you get on the 18-55. I don't miss the 50-55. The focusing feels faster that on the 18-55 (I swapped lenses 3 times to confirm this, focusing from infinity to a close object), but it's also more noisy. I was a bit afraid by the noise issue, but it turns out to be very acceptable to me (as long as it's dimmer than my shutter sound I'm fine).
The tamron focuses really close (I'd say around 10/12 cm from the lens extremity to the object from my tests), and in this respect is a great improvement over my 18-55. The 2.8 aperture is nice, especially for improvised interior pictures, when I don't want to use my SB-400. 50mm/2.8 is a great combination, I'm probably going to let my 50mmf/1.4 rest now that I have AF on this focal/aperture. Gotta do some chores now, but I'll take it to the garden nearby tonight for some sakura snaps If you have any specific questions about it, feel free to ask, I'll do my best to answer precisely.

Great write-up for people who are interested in this lens :thumbsup:
Looks like is better than 18-55 in every aspect, initially was afraid the focusing will be even slower than 18-55 like some reviews have suggested. Now really tempted to get one too.
Does it hunt a lot under low-light condition?
Well perhaps it was not clear from my post, but I was in fact talking about the Nikon 18-55 II (that came as a kit lens with my D40). There is a VR version which I never tested, equivalent to the Canon IS I suppose.
I'd much rather have the f/2.8 over the VR, especially so at the longer end (50 mm). I never used my 55-200 VR at 55mm for the sake of having the VR over 18-55.
Regarding the low-light hunting, I find it less prone to it than my 18-55, especially when helped by the AF-light indoors (I did some testing in my apartment by shutting off the lights and trying to focus various objects), which I guess is the logical consequence of letting in more light for the AF system.
Longer distance focusing is really better than the 18-55 (buildings from my window), it never screws up (my 18-55 sometimes can't focus properly on buildings at 55mm). I should mention it's completely dark out there now except for the city lights.
I should also mention that using short focals with the built-in flash on close objects does result in a projected shadow from the lens, as predicted by the lens notice. The lens is quite large (67mm filter thread), so this is to be expected. Not an issue for me because I have a SB400.
