"there's no such thing as a Pentax FA 18mm"
The pictures really cleared things up for me.

nice series.
Ha, some of the guys over at Dpreview were thinking the same thing

I mean there are some sharpening edits you can look at and for a few reasons have a sense that some software was used but yours do look better than many others and I would have thought great glass was the reason for that.
Nicely done. Images like these make me wish I had done better and gone back the second day at our last air show.
I guess I will go in my backyard and take a picture of a tree instead of aircraft.
Thanks for posting.
Wait. You used a teleconverter on that 200mm lens to shoot aircraft? Bold. But these turned out clearer than my 25 year old 500mm, so there you go.
Thanks, I guess I just shy away from more excessive sharpening to make sure I don't overdo it. My Sigma 70-200 is the older non-macro version and it's amazingly sharp even wide open. Some say it's as good as the FA* 80-200. I found that if I stop down to f/4.5 there is little quality loss with the TC.
It's funny how you mention going back a second day, I would have loved to try a different on the second day but sadly I had uni commitments on the Saturday.
