Originally posted by amazing_universe You also mentioned that all the previous pentax lenses will work with K3. Does it mean that all Lens features will work like auto-focusing etc. What should i look for in market place for K3 compatibility? I am happy to purchase some of these lenses from Marketplace if they are in good condition and seller is ready to ship it to Melbourne, Australia.
All lenses UncleVanya listed can be fully controlled by the camera - including Autofocus

Manual Focus lenses are K, M, A and M42 lenses (For M42 an adapter is needed).
With K, M and M42 lenses you can't controll your aperture with the camera, how to use this lenses is explained here:

With SMC Pentax-A lenses you can controll the aperture with the camera you just have to focus manually (Samyang lenses have the KA mount and work like Pentax-A lenses, for other 3rd party lens manufacturers you have to check for every lens if it has a K (all manual), KA (aperture controlled from the camera) or KAF/KAF2 mount (Autofocus included / all current lenses from Tamron and Sigma).
K, M, A and M42 lenses don't tell the camera what focal length they have so you have to insert this information manually or your Image Stabilization System won't work correctly.
