1 | Sigma fp (usability) issues | |||||||||||||||||||||||||
2 | This is a collaborative document for collecting and listing usability issues of the Sigma fp camera with the current firmware (1.01). It will be submitted to Sigma as a bug report. If you contribute, please only report issues that can be fixed with a firmware update. | |||||||||||||||||||||||||

4 | 1 - Bugfixes | |||||||||||||||||||||||||
5 | ||||||||||||||||||||||||||
6 | general (both stills & video) | |||||||||||||||||||||||||
7 | Summary | Description | Suggested fix | |||||||||||||||||||||||
8 | Touch screen to move zoom centre | Very time consuming to move the zoomed in part of the screen. Touch to choose a point then use the dial to zoom around | ||||||||||||||||||||||||
9 | Touch for QS | LH touch to select, RH scroll the wheel | ||||||||||||||||||||||||
10 | ||||||||||||||||||||||||||
11 | ||||||||||||||||||||||||||
12 | video specific | |||||||||||||||||||||||||
13 | Summary | Description | Suggested fix | user comments | ||||||||||||||||||||||
14 | CinemaDNG not standard-compliant | CinemaDNG files are not recognized by Davinci Resolve, Adobe Premiere and other programs because DNG sequences and .wav files have asynchronous timecodes and frame rates | Make CinemaDNG files standard compliant so that they recognized by Resolve and other compatible programs. | |||||||||||||||||||||||
15 | Black level changes during recording at certain ISOs on firmware 1.02 | The black level of captured 4K 12bit CinemaDNG sequences still "jumps" at certain ISOs | Make sure black level is stable and doesn't flicker regardless of ISO setting | https://youtu.be/gAE19PptAVQ | ||||||||||||||||||||||
16 | video recording unresponsive after using UVC | after plugging into a computer and using selecting UVC for a while, then unplugging recording will stop functioning. When starting a recording afterwards, the display overlay will freeze, the onscreen video will remain live, but all buttons become unresponsive. Even turning off the power does not turn off the camera. To restore functionality you must remove the battery or disconnect AC power. Still photos still work, however, you need to do a setting reset in order to restore video functionality | ||||||||||||||||||||||||
17 | audio level adjustment is deeply buried in a submenu | audio levels can only be adjusted when going deep into the camera menus | make audio levels available on the QS menu, and optionally on the rear dial | |||||||||||||||||||||||
18 | audio levels cannot be set to a low level | the lowest manual audio level settings is -36. This is still too much, and results in clipped audio, when using 'hot' microphones and loud sound sources (such as live concerts) | Make audio levels adjustable to (up to) -100. Give actual Gain (+), not Pad (-) instead. If Gain is fixed, use Trim instead. Proper indication as well (FS) | |||||||||||||||||||||||
19 | ||||||||||||||||||||||||||
20 | continuous focus Issue in cine mode | Still follow focus ion cine mode is big pain and needs to be improved...as for independent and bloggers its impossible to shoot with manual focus | ||||||||||||||||||||||||

22 | ||||||||||||||||||||||||||
23 | ||||||||||||||||||||||||||
24 | Audio specific @ClickCrabby | |||||||||||||||||||||||||
25 | ||||||||||||||||||||||||||
26 | Audio has randomly 1 or 2 frames extra | Audio file when recorded in Cinema DNG Raw then audio per clip records 1 or 2 extra frames and that too randomly on some clips - The duration of Audio to video is more by 1 or 2 frames | need the duration of audio to video exact same so there is no syncing issue | |||||||||||||||||||||||
27 | Audio has 2-12 frames | Cannot use cDNG mode. Importing clips in davinci means every clip has to be realigned | ||||||||||||||||||||||||
28 | No timecode on audio file | There is no audio timecode and every clip of audio starts from 00.00.00.00 - already issue with audio being one frame extra and no timecode to match one has to sync it manually even for just transcoding for NLE adaptation. | definately need the same video timecode to be linked with the audio. so when confirming the audio to pilot track one can sync the audio recorded on external recorder or devices. | |||||||||||||||||||||||
29 | ||||||||||||||||||||||||||
30 | No Audio Metadata | There is no Metadata for Audio to Video marriage of the file or vice versa, and for which reason there is no link of video to audio when recorded in Cinema DNG and has to be exported on timeline as seperate file. (no link) | metadata so that video recognises it has audio and Audio recognises it has video with it. so when video is dragged to timeline it can have audio file along with it and synced. | |||||||||||||||||||||||

35 | still photo specific | |||||||||||||||||||||||||
36 | Summary | Description | Suggested fix | |||||||||||||||||||||||
37 | 0.1s shutter delay | There is a 0.1s shutter delay. The recorded still image differs from (i.e. is 0.1s more recent than) the temporarily frozen image shown on the camera display after pressing the shutter. | ||||||||||||||||||||||||
38 | exposure compensation not easily available in M mode | in M mode, +/- exposure compensation is not available on a dial or button, which is unpractical when shooting with Auto ISO | make exposure compensation available on the QS menu (as a configuration option) and allow Tone & Color buttons to be optionally used as +/- exposure buttons | |||||||||||||||||||||||
39 | no DOF preview. lens always preview and focus at wide open. | Lens always focus at wide open, until shutter is pressed. bad design for large aperture lens, as many wide aperture lens has focus shift issue. | allow lens to close down aperture during preview. | |||||||||||||||||||||||
40 | Magnifier location select with touch | What's the point to focus dead centre and lose focus by recomposition | ||||||||||||||||||||||||
