I currently have some 10x43 and was considering getting some 8x43,same brand, frame etc....but when comparing FOV @1000yds, I noticed was 315ft vs 330ft. I was considering 8x hopefully to reduce eyestrain, and have a larger field of view...less scanning etc....but at 1000yds only 15ft difference? 10x are 25% more than 8x yet only like 15ft more view? that's like only 5% more FOV and that's at 1000yds!

Why get 8x if all they are is less powerful with the same field of view?
