Pentax W90 Lens features

The W90 comes with a fixed lens with a focal range of 28-140mm giving it a 5.0 x zoom which isn't really huge however it may be invaluable in a few scenarios.

At it's widest 28mm, the lens has an aperture of f3.5 and that is fairly sluggish and not very good for low light occasions and you will likely find it hard to get good bokeh. You could also have to raise your ISO setting which results in noisy photos. For the long end, 140mm comes to f5.5 which is quite slow and you would have to set slower shutter speeds.

Pentax W90 Connectivity

The W90 has the following connectivity:

  • USB Yes
  • Wireless Yes

Cameras which include NFC or Bluetooth support can be used wirelessly through smartphones. You are able to send images and oftentimes change camera settings with no need to connect physically with the camera.

Certain apps also give a Liveview and click the shutter in case you aren't near the camera. If the camera provides a HDMI port, it can be hooked up to an external display. A good number of cameras enable you to recharge the battery using the USB port.

Pentax W90 Video features

The maximum video resolution in the Pentax W90 is 1280 x 720 and you can save in Motion JPEG file format. 720p is awful for today's standards. You really should target at least 1080p resolution for decent video. The body doesn't feature a microphone or headphone socket which means that you have got zero control over the audio. It is perhaps a better idea to take a look at an alternative model if you want better audio for your videos.
