Lens Adapter Ring

Lens Adapter Ring
What size should I buy 2x telescopic extender for a 55 mm lens?

Hello, I am having trouble figuring out this. I want to buy a Telescopic 2x extender to get to the end of my 55mm lens. I found one I like, but that the sizes of 52mm and 58mm. What should I get? Do I have to buy also some kind of adapter ring to fit? Any help would be greatly appreciated. Thank you.

After reading your question again, now I want to use an add-on 2x lens. You will have to determine which specific filter thread size 55 mm lens is then buy that way. Most 18-55 mm Nikon lenses use 52mm filters from Canon and Sony 18-55 mm using 58 mm lens filters, etc. To determine the filter size of thread and go from there. If the lens are trying to connect the add-on lens 2x actucally uses a 55 mm thread, you must buy the add-on 58 mm and an adapter from 58 to 55 mm downstream. Using an adapter can cause some focus problems, but try the lens before you buy
