Third party's lenses

Question

I like to know which third party's lenses can I use for Nikon and Canon and it will be the best use, good performances?

Thanks in advance for your time.

Answer 1

Sigma and Tamron make third party lenses that fit Nikon and Canon cameras.

Personally, I won't use them. The lens is what gets the light from your subject to the camera sensor. The better that piece of glass is, the better your image will be. I've tried a few sigma's over the years and EVERY time, I ended up going back to a true Nikon lens. If you are buying on a budget, they are an alternative, but I wouldn't waste my money on them...
