Are you looking for just such a lens for your digital Slr camera?
Sigma has a lens that will step up to the plate for practically any situation. It is the Sigma 18-250mm f/3.5-6.3 Dc Os Hsm If Lens. And it is manufactured for Canon, Nikon, Pentax, and Sony Dslrs.
Canon 30d
This charm has been attached to my Canon 30D practically constantly since I purchased the lens. I have been highly happy with the images it has produced.
I have always been a fan of getting a best lens than the kit lens that comes with a Dslr because the kit lenses have been rated as lower ability than some of the other lenses that are available. I also prefer a wider focal range than what the kit lens offers.
I will admit that the kit lenses have been upgraded in the past year. They now consist of best optics and image stabilization. But the focal range is still only 18-55mm in most cases. Having the range of 250mm is a huge advantage. The optics throughout the whole range are strong. So you could have just one lens instead of two or three.
My personal findings are these:
- When compared to my all purpose walk nearby lens, the Sigma 28-75 (which has served me very well over the last 4 years), the image ability was equal or best in every shot. Plus the visual stabilization made it potential to take sharp low light shots without the use of a tripod.
- Compared to my Canon 70-200mm f4 lens, I was totally surprised that the Sigma 18-250 matched the image ability in every case. And, again, the visual stabilization made it potential to take hand held images that were not potential with my Canon lens (Canon makes a 70-200 f4 Is, but I don't own that one).
- The biggest surprise was when I matched my new Sigma lens up with my dedicated macro lens, the Sigma 105mm macro. The Sigma 18-250 was the hands-down winner in image quality. I could focus on a bee conference pollen at less that 2 feet away using the 250mm focal length, and the sharpness was best than the dedicated macro lens.
