Anybody has experienced which one better?
I wasn't aware that Canon actually had an 18-200 lens. Were you mistaking that for Nikon's 18-200VR?
That's true, let me edit, just between sigma and tamron. I have canon xsi with 18-55 IS. Looking for second lens with stronger zoom for in and out the door. Thanks
Sigma's 18-125 is rather well thought of.
There is a 55-250 out now which would take you further than your 18-55 IS. That strikes me a nifty lens.
Actually, Canon is planning to make EF-S 18-200mm f/3.5-5.6 lens. Look at this news (its in the Dutch). Canon is going to offer it in the middle of September.
I have the Tamron version for my 40D and its OK for outdoors during the day when you have plenty of light and thats it.
Its a slow lens that struggles in low light. I was in a Gym the other day trying to take a few shots of my nephews playing basketball and it was frustrating...even in a reasonably well lit gymnasium it was insufficient. I am saving for the 70-200 F2.8 IS
The Sigma has an OS version of the 18-200mm which is better than the non-OS version in terms of optical quality. And the OS for sure help in a situation where you need a slower shutter speed.
As for the optical quality, according to the web reviews, the 18-200 OS lens from Sigma is not tack sharp. The optical quality depends on the what focal length and f-stop you are shooting with.
If I am in the market of buying the 18-200mm lens for Canon, I will look at the Sigma OS version. And of course, wait a little longer and see how well the new Canon EF-S 18-200mm F 3.5-5.6 IS lens is. So far, the price/optical quality of the 55-250mm EF-S lens is pretty good. Hoping that the new lens is as good as the 55-250mm.
The recent issue of American Photo magazine named 55-250mm EF-S lens the best buy.
Hmm.... At 18-200 sounds rather nifty. Handy length for weddings. The only downer is the slow f5.6 aperture.
This is a generality, but between sigma and tamron I've always been more impressed with sigma picture quality, however tamron's build quality is FAR better then sigma.
I typically lean towards tamron, since a lens isn't any good to me if it's broken.
oh .... i thought usually the built quality of the Sigma lenses are better than Tamron
