Summary: Sweet spot is bottom right corner. Bottom left corner is hard to get completely sharp. Wide apertures don't work so well unless you're close to the subject. Once you get used to it, very sharp & great colors! On my D600 75% of the time, shooting portraits & weddings!
Summary: It's a great Nikon AF lens. It is NOT small or light…but a beautiful lens that produces fantastic images. Because I was on a search for a F1.4 "Museum Lens"…I decided to try this. I have a 50 and an 85 but I am still searching for the "right" lens to use in museums and churches while traveling. Now I am looking at the 24…but it seems kinda crazy to be spending so much $$$ just trying to find the "perfect travel lens for indoor shots".
Summary: Great lens love the focal length wish it handle chromatic abbreviation better but hey that's what Lightroom is for. I use this lens 25% of the time. It's great for those quick pix in low light. I recommend this lens.
