Pentax 645Z Video Review and Specifications

645Z

Bottom Line:

The Pentax 645Z boasts a whopping 51.4 megapixels and is the first medium format camera to offer video capabilities, but it also has a large price tag to match. The camera performs well for photography but has much to be desired in terms of video shooting.

Pentax 645Z Video Review:

The below video offers in a depth review of the Pentax as a stills camera and as  a movie making.device:

Video review highlights:

  • Body has lots of buttons which can be confusing
  • Incredible detail
  • Has shake reduction
  • Autofocusing speed is dependent on the lens; live view focus is just as fast as viewfinder focusing
  • Flash sync speed is still slow
  • Has the ability to tether
  • High dynamic range
  • 4K interval mode to make timelapse
  • Low light performance is excellent. Can go up to 12,800 ISO and still have printable shots.
  • First medium format camera to shoot video
  • Has highlight alerts, focus peaking
  • No focusing aids, highlight indicator when actually recording
  • Footage has a unique look
  • Don’t see true exposure until start recording
  • Video noise at 3200
  • Moire was produced
  • Footage imported to the computer for editing doesn’t look as good as it does in camera.
  • Has potential but right now this camera isn’t great for video work.

While the Pentax 645Z may not be the best DSLR for video production, it still is outstanding as a still image camera. If you’re looking for a better DSLR for video, check out the Best DSLR for Video article.
