Re: Live view autofocus on Pentax cameras

Hello mainoo

You did asked for the LV AF, but for your lens you must make a decision, if you will use them on FF or with a 1,5x crop APS-C. For example your 31mm is nearly a normal 46,5mm lens on a APS-C.

Only the K1 and K1 II are FF cameras. Their LV use CDAF and it is not so fast as cameras with PDAF/CDAF for LV. The only PDAF/CDAF for LV camera is the K70 and the new KF, but that are APS-C cameras.

The DA 55-300mm PLM is not a FF lens. I use mine with my K1 in the crop mode of the camera, or when I use FF, I crop later in PP.

I never tried out to use with my K1 the LV for a picture of a bicycle driver...I use the OVF and it's faster PDAF for that. So, sorry, I can't say much about that if that would work. I only see, that when I move myself and move to an object my LV focus is 'watching'  the picture is not in focus. For stills, the LV is good.

best regards. KPM2
