Nikon lens vs tamron lens?

Which is better tamron lens or nikon lens? What are there diffences?

Brand lens are always better. Yes, they might cost a bit more than the third party lens, but that's why you pay for quality and build.

Both makers have some excellent lenses. A great Tamron is better than a cheap Nikon and vice versa. You need to be more specific.

This is a pretty useless question. Both brands make some duds. No specifics… So… Neither!

Nikon makes a great 50mm prime.tamron makes a great affordable 28-75mm 2.8 lens comparable in image quality to the canon 24-70mm 2.8.without you being more specific on what you are looking for thats the best i can do.
