Pentax Plus Megapixel Lens Test

Author: John Honovich, Published on Nov 02, 2011

Last month, we released the first ever Megapixel lens test where we did a shootout between 5 leading surveillance lens manufacturers - Computar, Evetar, Fujinon, Tamron and Tuss. Member feedback was very encouraging and the lessons learned in image quality differences was quite useful.

One comment, raised by CCTV legend Vlado Damjanovski, was to test Pentax's Megapixel 'Plus' lens, a lens that he said performed quite strongly. We asked a number of camera manufacturers but it appeared that none of them used or had considering using Pentax lenses. However, with Vlado's recommendation and Pentax's marketing claim of 'innovation for installer friendliness' we decided to check it out.

The Test

We bought a Pentax Plus 2.8-8mm MP lens and did a series of shootouts against Fujinon's varifocal MP lens (YV2.1x2.8SR4A-SA2).

The shootouts were done in 5 different spots with a 720p HD camera:

  • 2 spots in the center of Field of View - one at 40 foot wide FoV (32 ppf) and the other at 80 foot wide FoV (16 ppf)
  • 2 spots in the fringe / edge of the Field of View -one at 40 foot wide FoV (32 ppf) and the other at 80 foot wide FoV (16 ppf); the fringe is important as image quality degradation is common here
  • 1 night time (under 1 lux) outdoors test to compare low light performance

Finally, and equally important, we did a comparison of the setup / focusing performance between the two lenses to better judge Pentax's marketing claim of installer friendliness.
