Thanks Brightcolors,

 

I do already have the Kenko 1.4x teleconverter. It fits on my Canon 100mm non-IS. The results are great! The only problem is the loss of light, although I think it's not a very big deal if IS works well.

 

I guess you're right. I will go to a store and try both. It's probably the only way to find out which one is better for handheld shooting.

Usually you close down the lens anyway, for macro stuff, even if only a bit. So now the TC already does that 1 stop.. no big deal in this case?
