Re: Phaco for Nikon SE? 20x oculars?

You also loose tons of field size.

Eh? Field size must be proportioned to magnification.

In my kit of typical eyepieces are a 20X with 12mm field, and a 10X with
18mm. So the 20X is one-third wider for a given magnification. (20*12)/
(10*18) = 1.33. The 20X/12 beats even an ultra-wide 10X/22.
