Originally posted by Tonytee I will stick to my trusty K100d Super camera.
If you're happy with what it does for you, there's no need to change.
But if you can use the improved IQ of the K-50, and great features like its focus peaking,
better viewfinder, or the continued option of using AA batteries in the camera body,
it would be a shame to miss out because of reported problems on the internet.
Out of around 1800 K-50 users on the forum, around 40 reported failures to the PF survey
Pentax Aperture Block Failure Survey Results - Articles and Tips | PentaxForums.com
If only 25% of the users with failed units responded,
that's less than a 10% failure rate over a couple of years' use,
which is probably around par for consumer electronic equipment.
And if you do have a failure, you have your K100d as backup.
