Only does that when you turn it on? 

Hello. I have a x-s10 that I use multiple lenses with. Yesterday I noticed that with the Fujinon 16mm lens I'm having issues auto-focusing. It works on video but not for still images. When I half press the button it focuses a bit then when I release the button it snaps back to the previous focus point. Even though it manages to focus the image is still blurry. Any ideas please. I already did a a major google search and nobody has mentioned this issue. Thanks, Etienne   

Hi everyone !!

X Raw Studio works with image files on your computer - not the image files on the camera card

Hello. Thankyou,now Is all more clear: I have take some time in your link. Let tell you. I has totaly forget this machine have "compress picture option" and not Only "compress lossless" anyway not change the experiment. RAW  and this last two format look like same result about Number of recording picture. Can tell all results in this: in raw you can make 17 pictures for second. Is wrong. Is about One single Press and wait buffer. Full 30/20/10/8 not change. After 17 Need Press again. You not can Press before "redgreen light recording Is on".   With preshot you can have 25  are more 7 pictures . The story change Only in jpg shot only. In jpg at 30 you have 30 picture but redgreen light off very Fast so you can shot very quicly. At 20 shot Is about start look like infinite shot. 60. So the best performance are this last One  about Speed and recording picture after camera working witout big limit. I want take a shot about Italy cyclet Just for passion. I think i Will use this last setting.  After Need check when battery not are full change and ambient temp.  Anyway my cam look like exactly specific about you link. Im Happy my cam working perfectly.
