Excerpt: Pros: <br />- small and lightweight makes it easy to carry around all day.<br />- fast lens- I use it with an underwater case to photograph fish while snorkeling.<br />- good light even in slightly darker places- indoor portraits or group photos for example <br /><br />Cons: <br />- this lens is fixed so it's not good for shooting subjects further away. As a result, this is a good additional lens but does not serve as a good primary lens.
Excerpt: I purchased this lens as a way to slim down my Nikon J1... I have the 10-30mm and the 30-110mm kit lenses, and found that the camera was just a bit too bulky to always make it out the door with me. The 10mm lens is noticeably smaller, although still a bit large to be pocketable, which was my original hope. While the size wasn't quite what I wanted, the image quality seems to be better than the two zoom lenses from my limited testing.
Pros: Easy To Use, Fast Focus, Lightweight, Sharp Images
Summary: This lens is proof that fixed optics are usually sharper than their zoom counterparts, until you get to the really big dollar glass. I have a Nikon J1 and have used this lens along with the 10-30 and 30-110 zoom lenses common for this camera. What's great about the 10mm is how compact it is and how sharp it is. Both things make it great for handheld "candid" photos, which come out quite well with the J1 being such a quick, compact camera.
