I hadn't noticed, but I probably would have sooner or later. No worries, it happens. I agree Busy makes that follow/unfollow button just a little too easy to click on, esp for the box that pops up in the right column sometimes. I've also accidentally unfollowed people before.

I have many different cameras. The one I use most often for my pro jobs is my Canon 5d Mark iii. For personal use I tend to step down to my canon 60d. In part because it's a bit smaller and therefore easier to carry around all day, and also my kids are grabby and if they break one of my cameras I'd rather it be that one. I also have many film cameras.

If you were in the market for a camera, and the one on your smartphone isn't enough, I'd suggest one of newer sony or fuji cameras. I esp like the fuji x100. They are small as the old rangefinders (kind of a budget Leica) and give a wonderful image.
