[Brightcolours]

Sillier it gets.

 

The Eg focus screens have the same thickness, thee is no variation in production. There are no shims involved when exchanging one for another, at all. The camera housing and focus screens are manufactured to such tolerances that once does not have to bother with shims when exchanging one Eg screen for another.

 

Like I wrote before, only when one gets a 3rd party screen fiddling with shims may be needed.

 

Do I have experience with exchanging the standard Eg-A II focus screen with Eg-S Super Precision focus screen? Yes I do. Do I have experience with manual focussing with this screen together with shallow DOF  of f2.8, f2, f1.8, f1.2 lenses and their shallow DOF? Yes I do. 

 

Can one get accurate results, manually focussing with Eg-S and large apertures? Yes one can. Is it fast and easy? Yes, indeed.

 

Do trolls want to troll? Apparently.

 

When I manually focus through the viewfinder with the Eg-S screen on the B, the resulting image is focussed on the B, even near MFD (0.6m).
