Barb's trick got me thinking...
Several years ago, Microsoft Research had a project to use early generation Windows Phone devices to take close-up pictures. They sent out free devices (like the one in the first attached picture) to those of us that requested them. I still have mine.
Once I found where I had placed it, I took the following two [2] close-ups with my Surface Pro 3: one before and one after I taped the magnifying glass to my SP3.
As you can see, I took the close-up with the magnifying glass much closer and it is still much sharper.
It's certainly not a replacement for the better camera that we really deserve, but I thought I'd share.
