Originally posted by Kevin1961 Hi. I have just bough the K20D and it shows the fireware as 1.00 has there been any gig changes between the one I have and the v1.03. It seems as there are not any big changes from what I can see. All the best. Kevin
Kevin I installed this firmware update to my new K20D about a week ago, mine too was V1.00 when I installed the new update. I feel I have slight improvement in AF speed. From what I have read and what I gleaned from the Pentax website is that the V1.03 is an all inclusive update, in other words there is no need to track down a V1.01/V1.02 update first.
