I don't really think Olympus takes hoods seriously, except for the one on the 35-70/3.6 which adjusts the angle depending on the focal length. If the hood is perfect on the 40/2, that is, it blocks all light from outside the the diagonal angle(56 degees) of that lens then it allows the 24 degree 100mm to be flooded with light outside its field of view. The other thing that is half-a--ed in my opinion is the variability of attachment including screw in(the wide angles), clamp on(50/1.4), slide out(135/2.8) and bayonet(35-80/2.8). My 1964 Leica M3 had bayonet hoods that attached quickly and easily, the same way for all the lenses, and each one seemed to be carefully designed for the focal length and not to block the rangefinder windows. Maybe Mr. Maitani, realizing that effectively shading the lens with a hood is a crapshoot anyway, decided that it was better to shoot without one and pay attention to the light falling on the lens with every shot than to spend a lot of effort on something that even with the best design would not be effective in every instance anyway. I know I paid more attention when I shot without a hood than I do now. So you get afterthought hoods for those, like me, who insist on them.

Hmmm, we disagree on just about everything here. I think the accessory Oly hoods that I have (8 models) are well designed and matched. Two of the lenses for my Texas Leicas (Mamiya 6) have bayonet hoods and I find them significantly more fiddley to attach than screw-on hoods. I'm not crazy about the clamp-style but, at least for some w/a lenses, I can see how they were necessary to prevent vignetting while remaining small. The fact that I can nest several round hoods makes them a better option than rectangular hoods with very little trade-off in performance.

The 40mm hood is what makes that lens a joy to use (*much* easier adjusting f-stops). And they nest together, retaining the compactness. However, I do find the 40mm suffers from flair when shooting into the sun -- no hood can solve that -- so don't.
