definitely.. 1 of the most valued for money lens. and gives u a chance to try out manual focusing. but do try manual focusing on your kit lens. Its actually quite fun and addictive. But after trying and u think you wont like it, then dont get the 50mm f1.8. will have to get the 3 times more ex f1.4 then
If you prefer or you don't mind using manual focusing, its a great lens to have for portraits and other things. This is one of Nikon's cheapest lens but also one of its sharpest.
If you are using manual focus, your shooting style will be different. It takes a lot of practice. Can be quite frustrating if you are shooting streets or events coz things happen so fast and u might miss the shot.
Yes, as long as its AF-S it can AF on your camera. Take note though, the 50mm f1.4 have both AF and AF-S versions, make sure you get the right one.Thanks alot guys! The info was much appreciated . I was thinking if i should save abit more and get the 50mm F1.4? Whats ur opinion? So any lens with AFS can be autofocus with my D3100?
