Camera Labs

I'm planning to buy this lens but i cant find such review about it.

I need your suggestions and feedbacks. thanks.

Hello kyuuzou, and welcome to the friendly CameraLabs forum!
I've found no review of this lens on places that I trust, but don'T erxpect miracles from this lens. The predecessor (18-200 DC OS) was e.g. reviewed here.
I wouldn#T expect more from a lens that has an even larger zoom-range.

thanks for the warm welcome sir. if we compare the sigma 18-200 os with canon 18-200 or sigma 18-125mm os hsm is which one would yield better results?

The Sigma 18-125 is optically similar to the Sigma 18-200, so if it came down to a choice between them I'd go for the Sigma 18-200 unless you really really wanted HSM. The Canon appears to give better image quality, though it costs almost double what the Sigma 18-200 costs.

thanks for the very useful info. I would probably go for the 18-250mm dc os hsm. I'll just wait a bit for reviews and if the lens produces decent photos.
