Hi, I was thinking of getting the Kenko 1.4x TC. From what I've read, the Kenko 1.4x TC should be compatible with the ef-s 17-55mm f/2.8 IS. I know that AF might be a tad slower and that the max aperture would go down a stop to f/4.
Does anyone have this set-up? And if possible please post pictures on the tele-end at f/4 (55 x 1.4 x 1.6 = 123mm). I'm interested in how the bokeh turns out.
Thanks!
[edit]: I just read on Kenko's website that they do not recommend using the TC on zooms starting under 50mm. Can anyone confirm whether or not the TC will work with the 17-55mm f/2.8?
