I hope someone hasn't posted this!
I'm considering between the 18-200 and 18-250, but for the price difference, I wanna check on two things:
Does anyone have any idea what is the lowest fstop the 18-250 will go at 200mm? Is it also 6.3 like the 18-200 Sigma or around 5 plus?
Is the extra 50mm really necessary if you're say...the kind who love taking stage event photos, I'm not a nature person so no bird shots for me, so I can't relate to the photos I see here although they are BEAUTIFUL! =)
Thanks!

Hi Andrew, for this 18-250mm lens, the F-stop at 200mm is F6.3
u can consider this 18-200mm, if u dun really need the extra 50mm... that can help u to save a bit, just make sure u r comparing with the right model. So far there r 3 model for this 18-200mm... If im not wrong, the latest one come with the Hyper Sonic Motor.-Sigma 18-200mm F3.5-6.3 DC OS HSM
-Sigma 18-200mm F3.5-6.3 DC OS

HSM? That sure is new, Yeah I got a much lower quote, nearly 300 bucks lower for the 18-200 so I was wondering if I really needed it.
Thanks a lot for the info! I was especially concerned about the F-stop more cause if the F-stop on the 250mm lens is lower at 200, then it seriously has quite an edge compared to the 18-200 besides zoom capability.
Cheers!

Mine looks fine. Did you try shooting at higher f-stops, e.g. f8 and more?
You can also bring the lens alonside your DSLR down to the service center for them to recalibrate too.

More comments on the lens: mine is the Nikon mount. I've been using the lens for a couple of weeks now, and:
- The lens barrel has loosened quite a bit. It used to be stiff and hard to turn, but it's much easier now. It's not completely loose though, and I still require slightly more force to turn it from 150mm onwards to 250mm.
- The lens is sexy and complements the size of the D300 well, and distributes weight nicely between front of lens and end of body.
- Lens is sharp for me as far as my eyes can tell. Handheld shots at low light is aided by optical stabilization and I can usually get reasonably sharp images at speeds of 1/10 to 1/15 of up till 180mm or so.
On the other hand...
- Lens sometimes has difficulty autofocusing in low contrast situations, and certainly more than the Nikon 55-200m lens it replaced. This may be a major issue for interested users, so make sure you try it out thoroughly before plonking your $$$.

For it range n price is still a lot cheaper then canon n nikon lenses.
Wah the price is still 900-ish..
Hopefully Sigma will come out with new lenses so this price will become lesser
Sry, u comparing the Sigma 18-200 or 18-250?
If is this Sigma 18-200mm, its price r even cheaper by at least half...
eventhough sigman is 18-250mm .. it is still fair to compare it with canon 18-200 .. as the 50mm more is not gonna be that important as compared to focus speed and IQ..
