Originally posted by Newtophotos One of the many reasons I choose Pentax was for the dual wheels on my K-30. Being able to adjust shutter and aperture speed quickly is very important to me. That being said, why doesn't Pentax (or seemingly any other brand) make a camera with three wheels, the third allowing you to more easily adjust ISO more quickly than the menu? During a recent vacation, ducking in and out of ancient not well lit buildings, having an ISO wheel would have been useful.
Are you saying that you have to use the menu to change the ISO on the K-30? If so, that's really bad!! Ever since the K10D, the higher-end Pentax bodies have allowed you to change the ISO without moving your eye from the viewfinder. With the K10D and K20D you hold down the OK button (in the center of the 4-way controller) and spin the front dial to change the ISO. The ISO is displayed in the viewfinder, and on the top screen. With the K-3 you press the ISO button (which is just behind shutter release button) and spin the rear dial. Again, the ISO is displayed in the viewfinder. It should never be necessary to move your eye from the viewfinder to change the ISO setting.
I find it hard to believe that Pentax makes a camera that requires you to go into the menu to change the ISO setting. Perhaps they remove that functionality with lower-end bodies so as to create another reason to buy the higher-end cameras, but they shouldn't do this with something as basic as the ISO setting. This seems unlike Pentax.
