Canon FD 80-200 f/4 L

[dynachrome]

I have been reading about this lens for a long time but did not have one until today. It doesn't look like much and I haven't used it yet. I put it on an FTbN and I really had to keep my eye centered to focus. Then I tried it on an F-1N. The screen was an AE and the finder was much brighter. I think I will have my best luck using an AD screen. My copy is a little stiff zooming between 100mm and 135mm. Who knows how long it sat without being used. The focusing is fine. I haven't checked the sate code but it could be 35 years old.

The New F1 screens are much finer ground and.about two stops brighter than the FTb N because they were Lazer cut. The A D screen is intended for architectural photography, I use the A E screen with mine with no problems, but the correct screens for small aperture zoom lenses are the A.G or P.G depending if you want average or partial metering.

I don't yet have as many different screens for my F-1N cameras as I do for my F-1 and F-1n cameras. I find the older L screens with an F-1n about as bright as the F-1N screens. With slow lenses I often use a grid type screen. There is no focusing aid to block things in the center and the grid lines serve as a sharpness reference. I will try an LG screen for the lens on an F-1n.

As you write the "L" screens for the original F1 and F1n are also Lazer cut, and as bright as the New F1 ones.
The "G" screens for the New F1 have a microprism that is cut to a specific angle so that it doesn't blackout with small aperture zoom lenses.
