I just purchased the nikon 1 aw 1, waterproof camera, this camera is unique, as its the first waterproof camera with interchangeable lenses, and shoots 1080P video... it sort of reminds me of the old nikon nikonous...........I"m leaving on a cruise vacation in 2 weeks, I intend to do some diving and snorkleing, with my new camera
I"ll let you know how it works out

sounds to me, that you have unfortunatley gotten a defective lens
I would look to return it, or exchange it, before the warrenty runs out.......

absolutley, for a group that large, your 105, although, it is a portriat lens, its not a wide angle lens.therefore, you will have to make a decision, on a good, and fast, wide angle lens, something in the 2.8 range, for excellent results...........bon voyage, have a great time
