2x TC
Jan 12, 2012 08:55:29 #
Hi all. New to the site. I was monitoring it for a month. Lots of great info and pics.
My question is: What is the difference in a 2x TC which has 4 elements vs. 7 elements. Are elements the same as blades when referring to the lens connection?
Would love to increase distance with my 300 lens and have full connectivity to my Pentax 100D.

Lens elements are the individual pieces of optical glass or plastic that make up the lens. Eyeglasses have two elements - one for each side.
