sigma or nikkor lens.. which is better?
i am confused between sigma and nikkor 24-70mm f2 and sigma 24-70 hsm f2.8
also suggest me some must have lenses
thank-you
If you don’t have the money to afford a Nikkor 24-70mm f/2.8 then the Sigma doesn’t do a bad job for an after market lens.
The Nikkor is designed specifically for Nikon cameras and with the crystal nano coating works extremely well. I own and use this lens on a daily basis and can confirm that it is an excellent choice for any aspiring photographer.
