Fits well and seems to be made well, overall a great deal.
Works great for my 49mm threaded lens to use with the 52mm polarizer I use with another lens!
Tried a bunch and found the right one. This is it.
Works great.
I needed this to step up from a Pentax 49mm macro lena to a 52mm adaptor for a macro ring flash. It got me squared away on that.
Had to buy this to attach my 49mm lens to a DLC ring flash. Worked fine.
I used close up lens for restoring old photos. These rings help me to use my old close up lens.
Allows me to atach pericials smothly. Does not help with typing on small keypad!
