THIS IS A VERY IMPORTANT MESSAGE IF YOU ARE TESTING YOU HAF SYSTEM! I THINK (but I could be wrong of cause) A LOT OF PEOPLE ARE DOING IT WRONG. They are reading bad focuses while they are actually right!
After recent post and lots of threads reading because my camera’s focus was totally off I discovered that I was reading/doing it all wrong!
I can imagine that a lot of other 717 owners are doing it the wrong way also since I couldn’t find this anywhere in previous threads.
When in auto focus the 717 (like digital video camera’s) adjusts it’s focus automatically to get a rather sharp image on the LCD or EVF. So if you half press the shutter to achieve focus, as soon as you release the shutter it is achieving a new focus automatically.
This is where it went wrong for me! I got constant different readouts while the actual auto focus system worked correctly.
The way to read the achieved auto focus is to half press the shutter and then switch to manual focus to WHILE HOLDING DOWN the shutter all the time. The value read than is exactly the focus value determined by the auto focus system.
Maybe the procedure above was common sense for most of the users on the STF, but not to me. So for others who also didn’t know, I hope the read this post, which might prevent them from ‘thinking’ they had an HAF OOF syndrome while actually they had not! Like me!
My (wrong) previous procedure was to half press shutter in auto focus, release it, switch to manual focus, half press again and read the focus. If you were doing it like this you get a different (unfocused) reading all the time.
Hope this helps! Alex.
Btw. If anyone is using the wrong procedure but get constant results, I would like to know since than something else is different with my cam.
