Originally posted by morfic I was hoping it was a camera/manufacturer ID string change causing the ruckus,
While I cannot confirm if this is the only change in the firmware, I can confirm that what makes problem for K20D 1.01 PEF files to be recognized by Apple OSX (iPhoto and Aperture), Bibble and C1 is header information:
Firmware 1.0: PENTAX Corporation .PENTAX K20D
Firmware 1.01: PENTAX .PENTAX K20D
I have tried to replace the header with hex editor and after the change it instantly becomes readable by both Aperture 2.1 and C1 4.1. Btw, it is a complete pain in the neck to replace headers in each and every PEF manually! I did it out of curiosity, not masochism...
Since problem never existed with Lightroom, I suspect that Adobe checks for camera model, not manufacturer.
While I can understand the legal logic behind this move in Pentax (it is only a brand, not corporation anymore), the sneaky way it was implemented is ridiculous. How many important RAW or DAM software is out there? Not many and a simple informational e-mail to all of them BEFORE the fact could have saved some (much?) trouble to some (many?) Pentax users.
Hey Pentax, it is your flagship product you treat as an orphan and it is your customers you just fail to respect.
