I too am having problems with my flash. I can't seem to figure the whole thing out. I have a K20D, and have the flash set to automatic everything. I would think that it would just pull information fromt he camera and 'poof' get a perfect shot. NOT! The K20D is allot of work learning. I've had it for about a year now, and am still trying to figure the darn thing out. Give me a flash, and boy oh boy. More problems. It either over exposes or underexposes. Rarely do I get a shot that is 'perfect'. Don't know what I'm doing. Mostly in use with a DA 18-55 lens.
Oh, one more thing....in the manual it does not list K20D under the P-TTL mode, I'm thinking the manual was made before the camera came out...any thoughts there? Thanks.
