An update on using the 2x digital TC with the 40-150 f2.8 + 1.4XTC

in an earlier thread (http://www.dpreview.com/forums/post/56184669) I mentioned that I had experienced problems getting focus lock when using the above combination to shoot planes in flight at the Fairford Air Tattoo in bright, direct sun.

I took the chance for quick experiment using it today, grey but bright overcast with a bit of drizzle and found that focus was fast and consistent and looked pretty much "on-focus" (the IQ was pretty poor, as I would expect and the sharpness wasn't there either, even after liberal application of post-process sharpening)

It looks as if my focus problems were down to the conditions on the day (and maybe the fact I was suing a protection filter? haven't had the chance to test that yet)

So much to learn, so little time left to do it!
