Interesting, I wonder why you would have issues with soft focusing?
I'm curious if you (or anyone else) have used the 1.4X TC with the 70-200 f/4L on your XS. If so I would love some feedback as I am considering getting one to use with my L lens.
Not issues just a illusion in the viewfinder. Due to it being small you can't clearly see if your photo is well focused and then the results in the PC aren't good.
I've heard wonderful things about the 1.4 but it's pricey for just 80mm extra and losing a f/stop.
Way cool, Jan! What gear?
I used the Rebel XS of course with a 70-200 f/4L USM lens.
