What is so great about vented hoods?

[Bobbo]

As the title suggests, I am not wise in the ways of vented hoods... I know why a perfect hood is "perfect", but what is up with vented hoods, other than making them slightly lighter and easier to bend/break by removing reinforcing material? Help me out a bit here.

Thank you in advance,
Bob Clark

Since most of the time with RF cameras, we see the lens and hood through the viewfinder, having a vented hood gives you at least some idea what you are missing.

#edited for spelling, heh.

They do not block the viewfinder as a solid made hood could do. You can look "through" it.

Thanks a bunch,

now THAT'S a good reason to get something 😀 .

keeps your lens cool as well..

nah.. but seriously, in gusty situations, the lens doesn't get caught in the wind as much.

Well DUH!

I have a rectangular hood on one of my Oly SPs; not vented, but it looks way cool.

Beauty is certainly in the eye of the beholder! I don't like them because they make the front of the hood much bigger than necessary.

Peter: Yes, that is true ... maybe. I wonder about a rectangular hood being more efficient because it follows the format of the film. But that's probably not the case.

Along similar lines, and not wanting to pollute the forum with more small threads... are there any LTM or Leica M compatable lenses that don't have filter rings that rotate during focusing or aperture changes like my current lenses? I plan on going the Leica M route in the next year or two (one of the M4 variations with f/2 or faster 35, 50, and 90mm lenses). Not a big filter guy (red 25 for some B&W), but I like shades for the usual reasons, hence why I asked to begin with🙂.

All my lenses wear knit caps.

Actually I think it is the case. There's a guy over on PN who is constantly lecturing about that.
