Mods, please move this if appropriate, I've read the
Knowledgebase threads about using M42 M and K lenses (and the one about KA lenses on *ist), however, it states:-

so I'm starting here.
I have a significant collection of Pentax manual focus KA (and K) fitting lenses (that I use with Super A 35mm cameras fitted with motor-drive As).
I'm predominantly interested in aerial displays at airshows, and I'm therefore used to following fast-moving objects (albeit at a distance), although I also 'shoot' birds. I use rifle-stocks with a monopod to support long-focus lenses. Otherwise (ie when not at airshows) my standard-fit lens is a Vivitar 28-200mm (useful for static shots in aircraft museums - although I had to resort to the 18-28mm to get the Airbus A380 into frame!)
I am considering buying a K10D or K20D body so that I can take digital images as I shoot 6 to 10 36-exposure rolls at each show (I don't believe that the K100D or K200D will allow rapid-enough repeat rates for action shots).
I realise that I will not get autofocus, but, if I set the lens to 'A' will the exposure be correctly computed?
Can you give me a summary of the facilities (and limitations) that I can expect?
I read (elsewhere on this forum) that the SAFOX VIII AF system may not be 'state of the art' and I wonder whether for my application that manual focussing might be preferable (even with dedicated autofocus lenses)?
As I already have a wide selection of both prime and zoom lenses (all manual focus of course) I'm even wondering whether to opt for 'body only' . . .
. . . apart, perhaps, from getting a Bigma 50-500mm . . .
Does the image-stabilisation work with all lenses?
What are the disadvantages associated with using the image-stabilisation mode?
Are there any physical limitations restricting fitting manual KA (and K) type lenses (I have lenses from 16mm to 1000mm)?
