Canon F1-n focusing screen

I have all or most of the original or L screens for the first two F-1 models. The one I use most is the LD. This is a grid type screen. While it can be used for copying and architectural photography, it is also very useful for macro work and using slower lenses and zoom lenses. The grid lines are a good visual sharpness reference and there is no central split image or mictoprism to black out. The D screens are my default ones. The C screens are plain matte ones. These are useful for higher magnification macro work and for portraits. Why portraits? The C screen will allow you to focus on an important area, like a person's eyes, without having to point the center of the screen at the area and then recomposing. I have a fleet of New F-1 cameras. These have different versions of most screens with different metering patterns. They are less plentiful than the screens for the earlier models and much more expensive. I do have a few D and C versions but most of my New F-1 cameras have E screens in them. For general picture taking, they are fine.

The G screen is recommended for small aperture lenses and the I screen is a very specialized one for high magnification shooting. The standard E screen or L version should work very well with your 50 and 28 lenses. I have a few copies of the 70-210/4 myself. I think you will find this lens easier to use with a D screen. The D screen will work well with the other two lenses too and might help with composition with the 28. Having easily interchangeable screens is a handy feature but you wouldn't want to change screens every time you change lenses. I suggest that you find a copy of the manual online for your F-1n. There will be a section which describes all of the different screens.
