I'd like a lens hood for my FSU 50mm lenses.

I've narrowed the choices down to these two:

I suppose the tilted one should allow less disturbing viewing through the viewfinder, but OTOH could cause vignetting with wider lenses (I'm cosidering one also for my CV 35/2.5).


So which would you recommend ? Which would YOU choose and why ?


Thanks in advance for your opinions and advices.

I would not bother with either.

If the sun is in your eyes you will have flare in the photo.

It's life.

Spend the money on film instead.

(For what it's worth I got the second type, and have never used it as it makes the camera too big.)
 
I always (100% of the time, no exceptions) use a hood. It's as much for physical protection as it for light.

I prefer the second type above - I have both kinds shown. I have no vignetting issues using the conical type on a 40.

Same here...............Robin
 
If you will be using a lens cap in place while the hood is on, the straight hood may hold a snap cap more securely. My Leica, slanted, hood for my 50mm Summicron won't keep a snap cap in place for very long.
 
Spyderman,

The difference between both is not a question of taste.
It's a question of functionality.

None of them is supposed to cause vigneting. and the outer limit of the rim should be at the very same place for both.
The principle of the vented hood is that when looking through a reasonably offset finder (leica M, zeiss Ikon and so), you will see the front part as a line.
If you use the vented hood on a camera with a finder very close to the lens (barnacks), you will see the front of the vented hood at an angle, thus loosing a fair portion of the vision in your finder. Here on the contrary, a straight hood will give you a good vision.

So the question is: on which camera do you want to use the lens?
In theory, if I was using a LTM lens both on a barnack and on a M I should have both...
 
They are China made, right, pretty inexpensive i assume. So : buy both and check on vignetting for the 35mm.

Visually through the viewfinder, you will be MUCH happier with the tilted one!

AND: always leave it on; the lens cap will hold equally well for both types. Get the cap that is offered for the hood. it fits well!

Missed that...

Well, if the hood is designed for the 50mm angle, it will cause viignetting, wether it is tilted or not. Just a question of geometry.

My advice would be: try one of them, if it causes vignetting, I would try to machine its front and reduce its length (any CNC shop could do this...).
 
I have the straight hood on a J-3 mounted on a IIIc at the moment. If you use the cameras finder you see a small part of the lens barrel plus part of the hood. It is not as bad as you would think considering the hood is vented and really lets you see well through it. The best solution is an aux finder and with that I only see a tiny part of the hood barely intruding into the bottom frame line at the middle.

I should add I think I have used this hood with a Jupiter 35 in Kiev mount and not had vignetting.
 
Thanks for your comments.

I'd like to use it in these combinations:
Kiev + J-3 (with both the Kiev's finder and external finder)
Bessa + J-3 / CV35

I'll ask the seller about combined shipping and eventually buy 2 of each 🙂 (i.e. both types in 39mm and both in 40.5mm diameter)
 
One any camera the slanted hood is better for 35 and 50, since you can see through it.
The difference is a line in your FOV instead of a wide bar.

I use the Leica equivalents of your #2 above on both 35mm and 50mm Summicrons. They also fit on my CV 35/2.5 classic--albeit not so securely. No vignetting on the 35mm lenses. You should be safe with a 39mm tilted models.
 
I own both types of hoods in 39mm, 40.5mm, and 43mm. I just bought the new vented/tilted ones from HEAVYSTAR.

On the CV35 Skopar, I have the Voigtlander hood designed for that lens, it works very well, and I don't see a reason to change that out, although it won't take a lenscap.

I've been pulling XX film through my new M2 and CV35 Ultron w/vented/tilted hood, but haven't seen the results (yet). The 39mm hood is marked 3.5/2.8 and 3.5/3.5 so it is -probably- OK with my ultron.

I have a Canadian 50 Summicrn with the slanted hood. I discovered that the latest Nikon 52mm cap (pinch style) fits inside the hood, and stays quite snugly in place. No dust gets in through the vents, as the cap covers them, and the cap doesn't get knocked off.

I was quite happy to discover this.😀
 
So finally I bought both of these hoods and I can compare.

The tilted one seems to be less noticable (less intruding into view) on most cameras: Kiev, FED-2, Bessa R2 all you see from the hood is a line. But the disadvantage is, that there are 3 vents to look through, and the piece between them is quite wide. If it stops (when screwing it in) with the piece blocking your view I guess there is not much to do. The non-tilted hood has 6 vents, and the piece between is much smaller, so it's less relevant where it stops. I guess it would make sense on lenses with rotating front (like the last version of Jupiter-8)

Also, both hoods are the same length from filter thread to front rim. The tilted one can take 52mm filter (there is a filter thread! possible use of polarizer!) and cap on the front, while the straight hood takes 55mm cap (there is no thread on front, but the cap fits), so obviously there is less chance that the straight hood would cause vigneting.
