I did a quick search so see if there was any information here regarding these teleconverters but I didn't come across anything of value so please forgive me if this question has already been asked.
I own two lenses that I would like to use with the teleconverters. My Canon EF 70-300 IS USM f4 lens and my Canon EF 70-200 IS USM f4L. Now I know the teleconverters work best with F2.8 or faster glass but I don't own a f2.8 zoom lens.
My choice would be the 2x as it would make my 70-200L a 400mm and my 300 a 600mm lens, but I am not sure what the lower light would do for the autofocus and such. The 1.4 would be OK but then I would have to use my 300 as a 400mm. (420mm to be exact)
My question is, how are the optics with these teleconverters and what exact model would you recommend? Thank you in advance to anyone who answers my question(s). Oh and one more thing, I usually shoot with an f-stop of f8 or higher (f8 ~ f13) so keeping it in the higher numbers are not a problem.
