Pentax K20D versus Samsung GX20: What Digital Camera review

Yes they all will.

will the pentax lense fit the samsung because pentax they have some great ones

I have the GX20 and it is excellent - price decided it for me. But as they say either is a great camera. ISO is easily changed from the front dial - no need to go into menus. Makes you wonder: did they review it (ie use it) or just read the spec sheets...

Pentax have 21pics/sec (in low resolution.

Yes Samsung~~~ 89%!! WhatDigitalCamera is the BEST man!

no need to look so enthusiastic

HOLD OK BUTTON AND ROLL FRONT ROLLER, this is the way how to quickly and easilly change ISO..!
