21mm f/3.5 lens hood, B+W W/A Hood

I am trying to locate a METAL lens hood for a 21mm f/3.5 Zukio, but

it is very hard to find. I noticed that B+W had a 49mm thread metal

wide angle hood for lens with greater than 70 degree angle of view.

I think the 21mm has a 92 degree angle of view. Has anyone tried

this hood?

Dean-

 

I have this lens (great lens!) but have never had a hood for it. One was made- try this link for info.

and hoods are shown here!

Not sure about any third paty hood either since I know I have a hard time with polarizers on this lens as even a Heliopan slim will still vignette. I now use the Singh-Ray sproket polariser that fits in the P-mount.

 

Good luck!

The 49mm screw-in hood listed in the SIF is rubber, or at least the one I bought was made of rubber. The manufacturers often design the hood to work when a single filter is fitted, so as long as you don't use any filters you may might away with using the metal hood for the 24/2.8, which covers an AoV of 84°.

 

Thom, If a polariser is vignetting then I suggest buying a 55mm filter and using a step-up ring. This is how it's done with the 18/3.5, though Olympus' own step-up ring for that lens is 49-72mm! The Olympus polariser (made by Hoya, I believe) is very slim.

I'm wondering what possible reason you could have for insisting that the hood be "METAL?" In any case, Olympus outdid themselves in their quest for compactness when they designed the 21mm f/3.5. The tradeoff is that the lens almost vignettes even with the slim Olympus OEM filters. Most filters from other manufacturers do vignette slightly on this lens. You absolutely cannot stack more than one filter of any brand on the lens without causing vignetting. So ANY threaded lens hood you find that does happen to work will necessarily preclude you from using any filters at all. Not very practical, in my view.

 

Olympus engineers had very good reasons for making the 21mm f/3.5 lens hood a slip on design. And for whatever motive, they also chose to make it out of rubber. I personally can't see any reason to fault them for that. I think you'll find that it's not just hard, it's virtually impossible to find a metal hood that works for this lens, unless, as previously noted, you use a step-up ring.

Dean,

 

There is no Olympus-made metal hood for the 21mm lens. The OEM product is and always was rubber. You really need the OEM hood unless you can verify that the B+W hood is wide enough. The Olympus hood is VERY wide. Perhaps if you can find another maker's 20/21mm hood, that might fit, but I doubt whether it will be 49mm. More likely 52 or 55, in which case you'd have to use a step-up ring.

I have a 21mm f/2 Olympus lens and a 35mm f/2.8 Olympus PC shift lens.

 

The hood for the Olympus shift lens is the exact same one used for the 21mm f/3.5 Olympus lens.

 

(The 21/2 and 21/3.5 lenses from Olympus cannot use the same hood because the filter diameter of the two 21mm lenses is different - 21/2 = 55mm, 21/3.5 = 49mm.)

 

Does this (vaguely-related-to-your-question) trivia help anyone? I lost the hood for my 21mm f/2 lens on a job 18 months ago and have had trouble finding a replacement hood ever since. (Still don't have one!)

I don't have the original 21mm/3.5 lens shade. I have tried the 49-55 step-up ring on the 21mm/3.5 lens which can also take at least one (possible two) slim filter.

Thanks for the answers. I will stick with the OM rubber hood. I got a reply from B+W on their metal wide angle hood. They recommended the olympus hood also. Just a note. I use alot of Heliopan slim filters and they are the same thickness as olympus filters. I also have no vignetteing problems with a 49-55mm set up ring and Heliopan filters with this lens.
