Im looking to add a little more reach to my lineup.
The easiest and cheapest way for me would be to add a 2x teleconverter to the lineup.
What about the kenko 2x + 135L. On my crop that makes 430mm FOV f/4
I think the image quality will stay still very good since the 135L is a very sharp lens.
Will that work well with AF?
And will the MFD change after that?
