Re: [APML] Hutech 35mm Focuser

Focusing is very hard to accomplish accurately. Most people 
underestimate the difficulty. It is virtuallly impossible to get a 
really accurate focus by using a loupe or magnified on a screen, such as 
a Nikon D screen. You can get close, but not close for really high 
quality results, and this is especially true for a fast system.

The Hutech is, in my opinion, the greatest focusing aid ever invented. 
Its a circular knife edge made by evaporating aluminum on glass so the 
edge is very sharp and well defined. But the best part is that it 
matters not a whit from what azimuth you "cut" the knife edge. This 
takes most of the difficulty out of knife edge focusing. Since I 
purchased the Hutech and carefully measured it with a high quality 
micrometer to my particular camera, the focus has always been perfect.
