prospros

  • Its extraordinary color depth makes it perfect for portrait photography
  • The Pentax 645D is tropicalized - this means you can use it also in adverse atmospheric and environmental conditions without ruining it
  • It has fast shutter speed, ideal for action photos
  • The second memory slot makes the camera more reliable, also for professional use

conscons

  • Like it or not, we are too used to LCD display to do without it
  • Pentax 645D is one of the heaviest cameras in its category. This makes it less suitable for street photography and daily use, but it could be a plus since it gives it more stability if you shoot regularly with the tripod.
  • Unfortunately, Pentax 645D does not support wireless connection
