Rated 3 out of 5

Recommended with reservations

Bought this to use with a K-5IIs body I already own, for extended weight - critical hikes, as an alternative to a m43 camera. I expect it will perform well for that purpose. A purchaser needs to understand some limitations: 1. The lens hood is incompatible with most any filter, esp a polarizer, which could not be rotated with the hood in place. 2. The press-on cap fits over the hood, and is useless without the hood. 3. So, you will need to purchase 58mm filters of your choice, a threaded 58mm hood (foldable rubber would be good), and a 58mm snap-in cap (center-pinch to use inside your hood).
