A recent article in Outdoor Photographer mentioned using a tablet as a larger LCD screen for critical examination of your image while in the field. For the photography I prefer to do, it could be useful. Add in the various applications for camera control and possibly the option of additional storage, it might be time to purchase one.
My question is: which one? For my use, using it as a larger Live View would be desirable. Applications as a camera controller would also be useful. If it were tethered to the camera with a cable, that will work. As good as Cam Ranger looks, at +/- $300, I'd like to pass on that extra expense; at least for now. Perhaps use that money for a more useful device (Surface Pro 2 perhaps- would this work?). Apple iPad or Android would not matter. So, those who use a tablet, please offer a suggestion or two.
