Title: Proof in pudding
Review: I own an E-300 and a bag full of manual focusing Olympus and Pentax lenses, which I use in addition to some auto-focus 4/3rds ones. As a glasses wearer I was constantly adjusting my diopter and straining to get things into focus when using the manuals, the result being perhaps 25% of my shots being unusable.This little magnifier makes a big difference. On several recent outings I had absolutely great results. Most shots sharp and clear. There is a bit of a downside in that I have to work a little harder to see the readout in viewfinder, but I really don't need that.Don't expect an eye-popping change, but a change you will notice.Good product.
