I have become increasingly bothered by the sharpness of my 70-200f4L, and wondered if anyone knew of a downloadable test card I could use. I have read on this forum previously of people using various objects to test, but can't find the threads It may be my technique etc with the lens, but, I have been getting sharperer images with the 18-55EFS kit lens, so thought I would try a more scientific route to rule out the lens! I downloaded this but wondered if there was a better option.
Also, are there any tutorials on testing the lens that anyone can recommend?
Thanks in advance,
Garry
