Sorry, that's not an accurate perspective. Tulip hoods are related to how wide angle the lens is and the sensor aspect ratio, not zoom or prime.

Not to get into a tinklin contest here but photocat was correct in many ways. The Tulips are usually supplied with the zoom lens. The purpose is to reduce possible vignetting at the variable lengths.

Is that the only reason NO. It is most assuredly one reason. You do find the more solid barrel hoods on Prime lens too. So you are both correct I have the barrel lens hood type and sits on a 500 mm lens.

My 55 - 200 and other Nikon lens that are zooms all came with tulip type hoods HB32 HB 16 and such.

I think the original question had more to do with which one or do I even need one (hoods) to use on my lens and why.

The requester has obviously gotten a world full of ideas and suggestions. Now he will feel good to go outside and not use anyone of them.

Have a fantastic day and may the Hoods be with you.

“Vented hoods” and “tulip hoods” are not the same thing. The tulip design minimizes vignetting in the corners while providing optimal shading for the rest of the image. Vented hoods have circular slots around the circumference of the hood near the bayonet.

Seems to me. that you are mixing up a (Leica) vented hood, with a DSLR (Type) Tulip hood. Perhaps you do not know what a Leica Vented hood looks like, or you would NOT have related the hood in the context of vignetting. Misinformation sets a nasty snowballing action.

The tulip hood is made ususally for zoom type lens (not always) so that a various focal lengths there will be no vingetting

Prime lens tend to have a straight barrel look

A Leica Vented hood , is completely different to the Tulip lens hood. Why would you bring a different kind of Hood into the discussion? Misinformation creates a bad snowball effect.

The vented lens hoods obstruct your view less. You can see through the vents in them. I use them on my rangefinders. The are intended to be used with rangefinder cameras. The vents will serve no purpose on an SLR or DSLR.

I find it interesting. Pablo8 responded to my initial post with a snarky reply suggesting that I’m lame for owning an M3 and 50MM Summicron without knowing the intricacies of lens hoods. Yet, it seems that there’s more to the issue than Pablo8 initially contemplated. Multiple posts, civilized debate and good faith disagreements on the more subtle points of the subject. Pablo? I hope you learned something here, not just about lens hoods, but about misplaced sarcasm and the value of our collective consciousness in the HH community.

The OP was seeking information about lens hoods. Part of the response to that is providing factually accurate information. It is not correct that tulip hoods are exclusively for zoom lenses. Tulips are mostly needed for wide angle lenses, which can be zooms at the wide end, so thus they frequently have tulip shaped hoods. It is related to the aspect ratio of many films or sensors, but many primes of 35mm or less today have tulip shaped hoods. I also suspect that modern manufacturing techniques have enabled the production of tulip lens hoods economically.

Let's try to provide the best and most accurate information that we can. Disinformation is not helpful.

"I speak, as I find". At least I didn't bring Tulip Hoods into the discussion, to cause a wealth of mis-information. I know the difference between Slot vented, and Tulip hoods.

"Vented" hoods are specifically built for aerodynamics and speed. They cause less drag and when used in combination with Air Jordan foot wear v leather Oxfords and such, make getting in there for a close shot better. Hope that explains it. ;-^)

Some say the vented is intended to limit interference when looking through the viewfinder.

That's what I've found.

Hi Pizza Day, if you intend the hood to be used mainly or solely on the M3 you need the vented hood in order to not obscure VF/Rangefinder. Wish i'd never parted with mine.Enjoy !

I am buying a lens hood for my Leica M3 with Summicron 50MM f/2 lens. Trying to understand the functional difference between the vented vs. solid versions. Can someone possibly explain? Also, do I even need a lens hood for everyday out door (or indoor) shooting? Thanks for your help.

If it is a rangefinder only you need the hood. You cannot pick up stray light that is coming into your lens through the viewfinder, so, leave it in place.
