For Portrait Painter

I got these to help me see detail in the model while portrait painting. I also considered butterfly-watching binoculars and opera glasses (La Scala Aida 3x25), but settled on these for the following reasons: First, all the butterfly-watching binoculars that I could find reviews for were at least three times more expensive, out of my price range. They were also bigger and heavier. Close focus distance on the Olympus is 7 feet. I'm usually sitting somewhere between 5 and 10 feet from the model. Opera glasses have a slight edge here with a larger field of view at the same distance, and a closer focusing distance of 6 feet. I noticed a little more distortion around the edges in the opera glasses. The Olympus has rubberized eye cups, so they don't scratch my glasses. The eye cups extend for use without eyeglasses. The opera glasses had smooth polished metal eyepieces. They didn't scratch my glasses the few times I tried them, but they made me a little nervous. The Olympus has an individual diopter adjustment: what this means is that you use the central focusing ring to adjust for your left eye, then use the right side focusing ring to fine tune for your right eye. After that, you can simply use the central focusing ring to adjust for viewing at different distances. This flexibility was great for me because I frequently take off and put on my glasses when painting very fine detail. The opera glasses only had the central focusing ring. (Another artist I know had opera glasses which could focus each eye individually, but she bought those years ago and couldn't recall the source.) I have used these binoculars in an auditorium lit only by a high north-facing window, light enough to read but dim by photographic standards. The image in the binoculars seemed at least as bright as what I could see without them, but I didn't have a chance to compare the opera glasses in the same setting. Given a choice, I would keep the opera glasses as a backup and for the larger field of view, but if I could only have one, especially because I wear eyeglasses, the Olympus 8x21 is the best compromise.
