We have quite a few birds around our new'ish house and I'm interested in viewing them closer and learning what they are. It is also sparking an interest in knowing more about the wildlife in Norther California (saw some harbor seal pups a couple of weekends ago), particularly since our kids keep asking questions about the animals. I'm planning on getting some binoculars. Anyone hear know much about them? I've done quite a bit of research and I know that like all things optical you get what you pay for. But my questions are more about magnification. For me, and as someone who might start to wear glasses soon, it seems that 7x42 might be my best option, though I wonder if 8x or 10x would be better. These are for backyard and local use so portability is not a key criteria, not yet anyway. Any advice?
