Yes, that's why I would like to record 50 fps with a 1/50s shutter. For normal-speed scenes, I would drop every other frame, giving me: 25 fps with a 180° shutterAdditionally, if all frames are used (and not just every other frame), I could use the material as follows: 50 fps with a 360° shutter (yes slightly blurry, but I doubt it's so noticable at 50 fps? I assume the blurriness of 360° at 25 fps is much more noticable than 360° at 50 fps... but I may be wrong?)2x slow-motion at 25 fps with a 360° shutter (also with the blurry effect, but that might even be an interesting effect during slow-motion sequences) That's what I want: a fine look at 25 fps, but still having the option for special effects using the extra frames in post production (even if, for slow-motion, I have to accept a 360° shutter). But to allow that, I would need to record at 50 fps with a 1/50s shutter, which seems to be not possible with the Samsung NX1 (as of firmware v1.21). And I wonder if there are technical reasons, or whether it would be just an easy-to-fix firmware issue (and whether other cameras allow this mode of operation). I am aware of the drawbacks (higher bitrate, blurriness when all frames are used, etc.), but I still would like to have that option at least for certain recordings. For the same reasons, recording in 48 fps would be nice... P.S.: I just figured out the Samsung NX1 allows recording at 100 fps and 120 fps too! At least it looks like that to me... The ability is somewhat hidden here: Menu -> Video -> Fast / Slow Movie If the camera is set to 1920 x 1080 and a frame rate of 25, 29.97 (displayed as 30), 50, or 59.94 (displayed as 60), then the "Fast/Slow Movie" option seems to allow you to increase the actual frame rate up to "100p" or "120p" (I assume that is 119.880 fps). The frame rate in the header will be 25, 29.97, 50, or 59.94 though, but the recording seems to be done with 100 or 119.880 fps respectively. I didn't know this was possible! However, it doesn't allow you to record at 48 fps or 47.952 fps :-( The shutter speed seems to be limited to 1/125s minimum if you record at 119.880 fps. The same limit (1/125s) seems to be the case if I try to record at 100 fps by selecting 25 fps and 1/4 slow-motion. If I select 50 fps and 1/2 slow-motion, however, the shutter speed can be set to 1/60s. The latter behavior seems to be a firmware bug, I assume?
