It seems like budget cameras these days really put a very literal meaning to the word 'Budget'. Even though the Pentax Optio M20 falls in that range, it performs exceptionally well. I have to say I’m now an official fan of this company.
Design
The M20 may not be a sleek camera but then again it’s really not supposed to be. It’s pretty standard looking in fact. However it is light, weighing in at 170g and quite slim. The main weight comes only from the AA batteries it uses. As just a matter of opinion, I prefer the AA battery usage over Li-Ion since I can get them anywhere in case they run out. But to get the best out of the situation you can of course, use NiMH batteries that come with a charger. But then again you’re back to square one. Nevertheless, rechargeable is always a good option.
On the rear you’ll find a clear 2.5-inch LCD display sporting 115,000 LCD pixels. It’s equipped with an auto dimmer function that automatically adjusts brightness levels for viewing comfort under varied lighting conditions. The rest of the design with regards to the buttons is pretty much what you’d see on any other camera, with a menu button and the delete key that doubles as a Green (Auto) Mode key.
hello very good product
