/u/tracedef - if you want a relatively compact camera with a mic jack (and a headphone jack) that doesn't force you to deal with multiple lenses, I recommend a [$997.99 Panasonic FZ2500 20x superzoom bundle (with a free 32 GB U3 SD card)] (https://www.amazon.com/Panasonic-DMC-FZ2500-Camera-Ritz-Accessory/dp/B01N03B4D9//ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=battleforthew-20) as a budget documentary camera.

The FZ2500 can record at up to 4096x2160 pixel 'True 4K' resolution (the RX100 V, A6500 and G85 are limited to 3840x2160 Ultra HD). This camera also has:

• a relatively large 1" sensor for shallower depth-of-field than a traditional camcorder
  
  
• a headphone output
  
  
• built-in ND filters for shallow depth of field in bright sunlight
  
  
• slow motion at up to 120 frames per second in full HD resolution
  
  
• upgradeability to the professional ["V-LOG" color profile] (https://adorama.evyy.net/c/60286/51926/1036?u=https%3A%2F%2Fwww.adorama.com%2Fipcvl.html)
  
  
• splash-resistance
  
  
• 10-bit color depth and 4:2:2 color subsampling output to an external recorder (that just means a wider color palette than consumer 8-bit 4:2:0 cameras such as the RX100 V, A6500 and the non-LOG capable G85).
  
  With the V-LOG upgrade this camera can give you results like this in 8-bit:

  This camera will give you high quality 4K video and 20.1 megapixel stills in a compact, backpackable package for a reasonable price - plus it will give you room to grow if you ever need advanced features such as LOG and 10-bit (something mirrorless cameras in this price range [e.g., below $1000, with lens] cannot do)
  
  Hope this is helpful and good luck finding the right camera for your doc!
