You know something is a luxury/high-end item, when a lens hood costs $100, and a lens cap $50!
OK, a plastic lens cap is apparently included, but the lens is not exactly cheap (approaching one grand), one would think they might include the nice metal cap?
In the 1970s I used and loved an Olympus 35RC. The standard hood was effective but costly; it didn't come with the camera. My sister, who happened to be living in Tokyo, bought me a couple of replacements at a SUBSTANTIALLY reduced cost (compared to US/Canada pricing). Lens caps of the simple spring-loaded after-market variety did the job better than the original which relied on a felt-trimmed friction fit.
Later, flexible rubber aftermarket screw-on lens hoods did better duty than the available but costly hoods from Asahi for my Pentax Super Program and various lenses. The caps were never very effective.
Oh! On my first camera (well, first serious camera), Konica TC, I had a wonderful hood of rubber, which folded back over the lens when you packed in the camera. My problem with hoods is that they increase bulk so much, and makes the camera much more visible when shooting candidly.
... Ah, I see one can still get the rubber hoods (not the S/M kind), I'll look at that.
