Originally posted by Genshu I am frustrated focusing my K-x. I just can't tell if it is in focus or not. I added a split screen to help me focus but when the auto focus says it is correct, the split screen is off. I am about to give up on it which is a shame, I have a sweet Tameron 28-75 to go with it. Don't suppose anyone here can help me.
I had focusing problems on my K-x with the Tamron 17-50,
especially at the wider end.
The quick fix was to use the CDAF from live view.
It's slower than PDAF, but was always accurate.
Never bothered with split screens,
because of the hassle getting them shimmed correctly,
and their potential to mess with the metering,
or not work with slow lenses.
