p.1 #1 · TC's, WA adapters, lens magnification. Educate me?


Ok, a technical question for the pro's that I'm curious as to the answer of.

How does lens magnification play into the role of effecting something like a wide angle adapter? Lets say someone has a 27mm lens with a magnification ratio of .80 and they put on a WA adapter of .43. This changes the 27mm into around 21-22mm, correct (going off a review I read about an item)? If so, what is the math to determine the focal length outcome, and how does one go about figuring out the magnification of lens x?

I came across this - http://home.comcast.net/~NikonD70/GeneralTopics/Close-up/How_TeleConverters_Affect_Magnification.htm , but can't seem to find info about determining overall focal length when using a WA.
