Summary: Loving my Sony digital P200 camera, I could hardly wait to get the Telephoto Conversion Lens and adapter to hold it to the camera. Either I am seriously impaired, or something is wrong. It is unwieldy to attach, time consuming, and when the telephoto lens is attached, you cannot use the camera in any other picture taking mode. It must be fully utilized distance wise, any closer and you get a black area in the circle.
Summary: Previously I purchased a cheap generic telephoto lens for my dsc-w5. What a waste of money.. So, after purchasing this lens I was very satisfied. It is a high quality lens. Comparing the photos with the cheap lens and then this lens told me it well worth the money to purchase the Sony lens.. Note: This lens is for outdoor use only..as using it in low light conditions will cause a dark flare in the lower region because the lens blocks part of the flash.
Summary: This telephoto lens will only work if you zoom in greater than 2x. Anything lower you'll have a keyhole effect - this might make some sense because 1 * 2.6 will just give you a 2.6 zoom which the camera already has. But if you want a range of 4x..you might need the other 1730 which gives 1.7x additional to the range of your camera zoom (2 * 1.7 will give you 3.4 - maximum of 5.1x zoom on 3x).
Summary: Bought this Sony product hoping to get closer to far away subjects. This lens is not to use without a tripod due to the narrow field of view and prone to shaking. Quite disappointed by the results if you intend to use it for shooting moving objects (slow autofocus + lens too sensitive to movements = blurry photos). Unfortunately, I do not see alternatives for the Sony W1.
Summary: Went to South Africa on safari in NOV-06 and was obviously concerned about taking shots of animals that were at distance. Being a novice at taking photos I had purchased a few years back a SONY cybershot camera and had been pretty happy with the photos I had taken with it. Prior to my safari trip I did some research and came to the conclusion that I had 2 options (as info' I found on the WWW stated that you should take at a minimum a 30mm capable camera with you).
Summary: As far as lenses for an inexpensive digital point and shoot, this one does the trick. It's certainly not a phenomenal lens by any means, but it does provide a slightly better range than the camera itself. It's not going to get you Nat'l Geographic quality images, but it's okay for the camera series its made for.
