Summary: So, I'm not one to buy prime lenses even thought they are faster lighter and usually cheaper. I went ahead and purchased this lens to not only help me in low light indoor situations but also the weight of this lenses really justifies the purchase to me. The image quality is great but expect some vignettes when shooting from f-1.8-4. Great for family images. The auto-focus is extremely fast and quiet as well.
Summary: This was my first lens I used digitally on my D90 when I made my transition from film. The sales rep told me its a great lens for portraits, and they was right! But the quality doesn't just suit portraits as you can see from my sample photos.
Summary: I have been waiting on this lens for MONTHS + Months. I'm so excited to finally have it!! It works wonders outdoors. I don't have a speedflash (next investment) so indoors I tend to get blurry pics because of the low shutterspeed required for the depth of field (2.8 and lower). However, this is worth every penny.
Summary: This is the first lens that I bought, besides the one that came with my camera (a Nikon D40). There's no adjustable zoom (as with the kit lens), but I really like that, because it makes you frame your shot and "use your legs to zoom." You get some great bokeh with this lens. I've owned it for about three weeks, and I don't think I've used my kit lens since!
Summary: i am using it for past 4 months. i like it a lot, i took lot of photos of my friends with this they all amazed with the bokeh it produced. it worth the money i spent. on the down side at 1.8f, pics wont look sharp(they look soft a bit). once i figured it, i started taking pics at 2.2f at which pics looks good to me. auto focus is too good compared to my friends 1.4f, but with my personal experience 1.4f gives better pics than this(but its double priced.
Summary: This lens are very good. If you have full-frame camera, this is old-good 50mm, on crop this will be 75mm, so if you think to picture birthday party in small room with crop look at 35mm. Sometimes in semi-dark environments picture gets blurry, so be very very careful with settings on manual mode (I don't use auto). P.S. anyway, with this price you can't get better lens. Anyway this will be better than zoom lens (kit, or any other...
Conclusion: This is my first lens besides the 18-55mm non-VR kit lens that I use with my D3000. I am just beginning to expand my photography and I cannot believe I have used any other lens besides this one. The kit lens feels barbaric! The autofocus is super fast even in low light. The lens is a quite soft and fuzzy on the 1.8 end (why I gave it 4/5 stars), but the shallow depth of field makes it hard to focus at that level anyway.
Pros: Build Quality, cheap, Fast Focus, Lightweight
