<p>Thanks Bob for taking the time to explain it in great details. I really appreciate it.</p>

<p>Thank you everyone for your inputs. I'm not going to risk putting the flash on my Canon camera but wonder if I can use the Yongnuo YN622C to trigger the flash wirelessly without damaging the Yongnuo itself. A transmitter is on the camera hot shoe, the receiver is attached to the flash for the off-camera flash setup. </p> <h2 > </h2>

<p>Previously I was using a Pentax camera/flash system, and recently switched to Canon. I'm planning to sell my Pentax gears but want to keep the flash to hopefully use it on Manual with the Canon EOS cameras (5D M2 and 6D). I'm sure the TTL function does not work on a non-Pentax camera. Do you know if it's ok to use manual flash without causing any damage to my Canon camera or the flash?</p> <p>Thanks,<br> Hoang N.</p>

<p>Thank you for the info. I'm using Canon 5D M2 and 6D for serious works now. The Pentax has been mostly used for pleasure, when I don't want to bring along the bigger Canons. I'm glad I made the switch.</p>

<p>I have this lens on my K-7 for over 3 years and so far have been quite happy with the quality of the lens, and the photos it produces despite the slow AF. Recently, I've been having difficulty with the lens trying to lock focus. It takes a long time (10 seconds) for it to autofocus, and this is not due to low light, lack of contrast or shooting against the sun but under normal lighting situation. I don't know if it's the lens or the camera that causes this but if someone has similar experience please share.<br> Thank you.</p>
