Testing with Canon EF 85mm f/1.2L II USM
No bad at all considering all the fuss I kept hearing about how hard it is to manual adjust the focus with the Canon EF 85mm f1.2L II USMThe Canon Eg-S Focusing Screen helps a lot too and I’ d suggest you get it if you have a Canon 5DmII too. It’s only $45.00 from Amazon
but keep in mind that the Super Precision Matte screen improves the ease of focusing when doing manual focus, but it’s not recommended for use with lenses slower than f/2.8. With these slower lenses, the viewfinder will actually look darker then with the standard Eg-A screen.
If you do install the Canon Eg-S precision matte screen, do not forget to change the C.Fn IV -5 setting to match the focusing screen type. This is to obtain correct exposure.
The full frame sensor of the 5Dm2 and its depth is a dream come true! Picture taken @ 1/2000 sec. f 1.2 ISO 400. Click thumbnail to see a larger image.
