Just try to keep within f8 and f11 and you'll be fine. I use mine at as close to those figures, hand-held at 1/320 and it works fine. After all it is a cheap lens so you cannot expect perfect shots from it all the time. You just get lucky sometimes, preferable with the important shots! For tripod and "macro" it's no slouch either, have some good "macro" shots with this lens.

Also here's one at 1/200, f9 hand-held (will load it full size tomorrow)

Hi guys, Just proved to myself and anyone else that's interested! You CAN fire the remote from behind the camera! Just set up a small mirror with the remote receiver (flashing) in the mirror and aim remote at that. Works like a charm so far. I have to try it outside and increase the distance yet but indoors, works great!

Thanks so much, I'll have to study this before diving in at the deep end, so to speak.

Hi everyone,
Having upgraded to a Pentax Kx from the older Pentax SLRs, I find that the manual focus on the K-x is a real pain in the butt! Thinking of selling and getting a Pentax dSLR with a split screen, that is of course if there is one available. Can anyone point me to the right buy, please?
Love the high ISO on the K-x but would rather have a decent focusing screen, am I alone in this quest?
Thanks in advance for any help.
