Summary: This lens is simple to use and produces very nice pictures. It works better in low light than the 20-50 lens that comes with camera. Serious lens but not seriously heavy like the similar lens on my old camera.
Summary: Great lens right here. Its not too heavy. I take it hiking worn around my neck for hours and its not awkward at all. I am hoping to capture a cardinal on a tree with a snowy background this winter. The manual focus is easy to use. Without a tripod you will need a very steady hand and some luck to capture moving objects from far away.
Summary: Added this lens to our camera for a safari we took. It got us some amazing photos on our safari. Lots of the other folks were using auto-focus cameras and getting frustrated as their cameras were focusing on branches or shrubs, and we were able to zoom in and focus on the actual fur or eyeball of the game!
