I was looking for a magnifier that was very compact but powerful enough to work with a medium format digital back. In a way, this one fits except for the magnification. It didn't seem powerful enough to me, and the all-round vision still doesn't allow me to look into corners. It does not include an opaque skirt like my other magnifiers. I would return it to exchange for a 10x, same size and price. In any case, these shortcomings are mainly due to my particular expectations and not Pick's faults. The lens was well corrected, although perhaps not the brightest, showing slight distortion from side to side. I don't use a scale so I have no comment on that.
