THE T-A-C CONTROL OF THE XPRO2! One of the biggest complaints I see on the Xpro2 is it's lack of ISO soft control within the camera via one of the command dials. I have to agree, being pinned to setting a hard ISO via the top wheel is somewhat awkward, and slow. Although I have gotten use to setting a hard ISO with the wheel, there are a few things you can try as an alternative! I'll also talk a little about controlling the shutter speed of the Xpro2. Within the camera menu, under the camera icon, - Auto ISO, you'll see three separate Auto ISO presets. Within each preset you set the parameters to which the camera will enable once the camera is set in an Auto ISO mode. Set your top wheel to the red "A" and you're in Auto ISO, and the camera will use whatever preset you have currently selected. In each preset you'll see three parameters, Default Sensitivity - Max Sensitivity - Minimum Shutter Speed. Default Sensitivity is the lowest ISO setting you desire, Max Sensitivity, is just that, whatever you want as a Max ISO setting, and Minimum Shutter is set to the speed you think you can hold for a crisp shot. There are a couple of caveats, the first is you can't set your default any lower than 200-ISO and if you set you default sensitivity at a higher value than your Max sensitivity, it will default to any ISO value you have set within the Max sensitivity parameter, regardless of the lighting situation. Yes, you can use that to your advantage, but more on that a little later! I said a couple of caveats, make that three, the third being you cannot set this Auto ISO preset to the "Q" menu, you can however set it to a function button. Mapping the Auto ISO presets to an arrow button makes for quick access and quick changes. Getting back to that advantage above, I set my last Auto ISO preset to a reverse value so that it will default to whatever I have set to the Max Sensitivity value, in this manner it basically forces the camera to a set ISO. Is it quicker than using the top ISO wheel, perhaps, that all depends on the user, it is in a sense, less quirky! So, whatever preset you have selected, the camera will use those parameters to set an ISO. Oh, but there's more! You'll notice in the photo my Xpro2's shutter is set to "T" and the compensation dial is set to "C" Let's talk about the shutter speed first. If you set the top dial to a shutter speed value, the Xpro2 will allow you to adjust that value with the front command dial by 2 - 1/3stops in either direction and not any further. If you set this dial to "T" you can run the full spectrum of ISO's by 1/3stop increments. Now let's get to the "C" by having this set to "C" on the compensation dial, you have 5 stops of compensation. You activate that compensation control by pressing in on the front dial, this locks the shutter speed and now gives you control of the compensation value. Pressing in on the front command dial gives you control of either the shutter speeds or compensation values. With the camera set to "T" "A" "C", along with the Auto ISO presets, controlling your exposure can be both easier and quicker!
