Premium Member Will Montgomery Posted December 8, 2005 Premium Member Share Posted December 8, 2005 I recently shot this footage on my S-16 modified K-3. The text in the sign was completely in focus through the viewfinder when I began rolling. The first shot is from the first 3 frames which were in focus, then the 2nd still is about 6 frames later where it became out of focus and stayed that way through the rest of the scene. I will of course run a focus test on the camera, but I was interested in what might cause something like this... Could it be: 1) The pressure plate not pressing the film properly? (I carefully check upon loading to see if its seated properly) 2) Something in the S-16 conversion causing issues? The gate's too big or something? 3) An issue with the transfer house? (this was done on what they call a "Y-Front" at Video Post & Transfer in Dallas, a very good telecine house in this market) Any ideas would be appreciated, and I will shoot a focus chart to double check with each lens I have.

(I carefully check upon loading to see if its seated properly) Don't know the K3 but I have seen that happen on other cameras when the pressure plate was loose. -Tim Link to comment Share on other sites More sharing options...

Playing with the pressure plate at the same time will answer the question! Stephen Link to comment Share on other sites More sharing options...
