I recently got a Nikon D7000 with a decent kit lens, 18-105. I was checking ebay out for fun to get an idea of what lenses are out there. Saw this neat lens that is basically an addon for an existing lens. It's a wide angle and macro lens in one. Was not expensive so figured what the hell. Well it came in... does not fit on the existing lens. I figured this was all universal but apparently not! It's too small. It says that it's compatible with the D7000 but I really don't know how. This is the lens: http://www.ebay.ca/itm/350747350419?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
So I'm guessing there are different sizes and it's something I need to watch out for when I order stuff. Where can I get more info on this? I figured this was all universal as long as my camera is listed. I'm guessing I can maybe get some kind of converter? Though I don't even know how well this works with the lens I have since holding it in front it's blurry and wont zoom. So I think it's one of those things where you get what you pay for, best to get a dedicated lens I guess.
