There is no risk of losing a shoot because an optional ISO user definedfunction on the wheel. That is not the case with the shutter function which is the stock function of the wheel.
Those who use this camera to make a living, as do I, and do so at times when we must use the 14-140 in rapidly changing dynamic conditions are well acquainted with the juggling act that goes on to dance through the menu trying to re-designate a gain detent with a better ISO setting while your shot walks away. If we had a faster zoom lens, perhaps I wouldn't need to get to the iso so quickly. Having the ability to dial it in would be much more useful than the shutter, and far less dangerous. Indeed, there is no greater danger with ISO on the wheel than there is with it on the three position switch. I hope it is an option that can be made available.
