Originally posted by just_life_photograph I currently own a K10d and have a number of lenses and I'm currently shopping for a flash that can bounce and swivel. In the future, I want to upgrade to the K3ii. My question is, will the K mount lenses that I have and the flash that I'm shopping for fit the K3ii?? And then, I don't think it will ever happen but would these lenses and flash fit the K1?
Thanks forum people!!

Other than a few sigma models most k mount lenses should work on all of these camera and even the sigma lenses only need a small update for the k-1. How they work is mixed, basic k,m, and A are All manual focus. The A lenses aperture can be controlled by the camera and can therefore the lens Will work in Av mode. The f, fa, and DFA lenses are made for full frame, these should work on the k-1 without needing to use crop mode. The DA lenses are made to work on cropped sensors, but sometimes they cover nearly the entire full cover frame sensor, some don't but often they cover at least a little more than the cropped sensor.
As for flash, we really need more info about how you want to use it. Fully auto and simple probably means a p-ttl flash. This site has gotten a little out of date but still has some good info:
