I like the beauty of my 2.5 times front area, because you can see a broader view. My 3.5 x is good for anything else, especially in the back.
My point is, if you want anything more than 3.5 times, you'd better get a microscope. Big maggie is a little too heavy, a little too long.
I want to get 2.5 x micros from DSV.
I'm sure I'll agree - it's not cheap, make them custom fit.
