I am wondering what is the end result between the :-
a) Kenko 2X Teleconverter vs
b) Kenko Extension Tube.
I am confused, please help. To my understanding a Teleconverter is to double up the focal length says: 100mm shall becomes 200mm but with loss of 2 stops of light.
The Kenko Extender Tube (Hollow) is to add below lens and body (same as above) to bring the subject nearer to you specially for macro shooting. It will loss of 2 stops of light too.
I have below pic to show the setup. Standard distance of 1 foot and shoot subject with & without Teleconverter. I can see that the subject is closer at almost double when I added the Teleconverter 2X.
What about using Extension Tube? Any one have it so care to share this confusing matter for Newbies?
#1 Setup at 1 foot distance between subject to Lens
#2 Shoot subject with only 100mm Lens.
#3 Shoot subject with Kenko 2X Teleconverter added btn Body & lens
