Yeah. if you want to shoot with a variable F stop lens, go ahead.The Sigma is a 4.5 t0 5.6 lens.The lens I choose to shoot with are all Nikon and they are all fixed F stop, most being 2.8 F stop.I consider a 4.5 lens a very slow lens and it is not a lens I would ever use. Then again a lot of my shooting is in low light so your mileage may very.Perry
