I attempted to install the FU-4 (grid) focusing screen into my new Aria and encountered some difficulty. I neglected to remember that the Aria owner's manual directs one to follow the installation instructions therein and NOT the instructions that come in the box with the screen. The drawings of the "lug" that one must manipulate differ between the two instruction sets. Properly, one must use a fingernail, or similar thin tool I suppose, to release the catch that keeps the hinged screen in operating position. My father taught me as a teenager decades ago not to let my fingers approach the mirror area. Famed underwater photographer Norbert Wu says to not even LOOK at the mirror when the lens is removed. Thus, using my fingernail was one difficulty for me. Owing to familial essential tremor, my hands shake, but not severely yet: another difficulty. With the frame swung downward for installation, the metal frame is only a few millimeters from the mirror surface. Lastly, the screen fit snuggly and it took many attempts to position it within the shallow, thin frame--without touching the screen or the mirror surfaces--and then use the tweezers and finger to snap the frame back into locked position. Once there, of course, debris had fallen atop the screen and I had to swing the frame down again, and so on.
Thus, my advice to anyone who reads this is to remember to follow the appropriate set of instructions and to be prepared to take time, patience, and perhaps a clean and quiet work environment.
I have changed the focusing screen in another modern camera, the Canon A2, and it was simpler but also difficult to seat the screen squarely without touching it.
