Beautiful Hoods...

They do not seem to be too practical to me; the purpose of the cutouts is to give a wider view through the viewfinder. Obviously a series of round holes is an inferior design to a wide cutout.

I suspect whoever designed them is unfamiliar with CAD-design software and could figure out how to have the CNC mill drill holes but not to mill elliptical vents...and possibly doesn't actually know what the vents are meant for.

 

However if they are a cheap enough alternative to the real McCoy and do the shading job correctly, it wouldn't be that big a deal to hand-modify several holes together so you had a proper vent to align with the viewfinder.

If they are screw-in hoods, then possibly the designer realized he could not make one with the cut-out that aligned properly on all lenses, so he chose the many holes. Also, I doubt the eye can resolve those holes; they might appear as a modest blur and still provide more of the frame.

 

(Speaking of hoods, the rarest one I know of is for the Zeiss Biogon 75mm for 4x5". I swear I have the only one in existence...but then I am prone to swear. :))

You might be quite correct about the designers' reasoning, but, have you looked at a vented hood through a Leica M viewfinder? The hood and vents appear quite crisply defined. It's not like looking at them at the same distance from your naked eye.

 

I have a hood which was originally meant for the 35/2 Konica Hexar-RF lens, which is vented and 46mm screw-in. The hood turns about 90 degrees within the part that has the male threads. Stops at each end of travel allow for screwing and unscrewing, then once it's screwed on you can rotate the hood so the vent is perfectly aligned. I used this hood on my 28mm Elmarit and CV Ultron when I had an M8. Quite elegantly designed, and I think I paid all of $30 for it.

You are right. I snapped on my somewhat crushed, but functional original hood on the pre-ASPH 35mm Summilux to be sure. I just don't 'see' the interference now due to habit and shooting with both eyes open, but anyone else might.
