Tube Adapter Nikon
Confused as to what is a filter thread?

I have a Nikon D3000 and a 18-55 mm lens. On ebay, many of the filters of the fisheye lens and accessories say things like "This filter fits any lens or lens conversion adapter tube, etc with 52mm threads for connecting the filter face." I'm so confused, what is meant by wire front? my thread is 55mm in front? : S and this fit my lens? # You http://cgi.ebay.com.au/42x-Wide-Macro-Fisheye-lens-NIKON-d40x-D3000-D5000-/260599379704?cmd=ViewItem&pt=Camera_Lenses&hash=item3caceef6f8 ht_4859wt_989 said that, although I'm not completely confident. Thanks heaps

A class in photography could eliminate confusion. And do not be surprised when fisheye converter is not. A fisheye lens by design has a viewing angle of 180 degrees. In other words, if you were to look through the viewfinder, rectum, see your feet too old. of these "add-on lenses only distort the image and make it look the way a fish-eye looks. Good luck, but I suggest a real camera store and try one before spending about U.S. $ 60. EBay's announcement called a professional high resolution "." If that were true, Why do you think a professional photographer to spend $ $ 1,000 a true fisheye instead of less than $ 100 for one in the link?
