Lens hood for Jupiter-3

I have had similar problems with small diameter hoods. I now use a large diameter push fit hood.
The one I have is to fit 42mm ( the external diameter of the J3) and takes a standard 55mm snap cap. This seems to works well with the J3 as filters can be fitted regardless of the hood which pushes over the outside of the filter/lens and its large enough not to give any vignetting problems

This one on ebay looks similar http://cgi.ebay.com/42mm-push-fit-B...emQQptZLH_DefaultDomain_0?hash=item563799ce47


edit - the lens hood is pictured attached to my J3 in my avatar pic

I should say the hood I have does intrude into the viewfinder on my IIIg and FED 2 but despite the masking I really haven't found this to be a problem. I have found the trade off of seeing the whole frame or having a deep lens hood to come down on the side of the hood. As it's a push fit you can always pull it off if you really need to see the effected part of the frame or for times when you simply dont need a hood. If ypu do use one it also has the added benefit of pushing up against the aperture ring which helps hold the ring at a set aperture.
 
Yes, there are more advantages than disadvantages, firstly the fact that this is a bayonet and not a screw mount... I must absolutely try it!
 
Yow! Are you sure the heavystar lens hood vignettes on the J-3? I've been using it and saw no vignetting, but I guess you need to use f:22 and a distance shot to tell for sure. I always have a filter on my J-3 at least for protection.

One option, if I must, is the rectangular FSU lens hood. The one that has the price molded in (25 kopecks). Tells you something about a managed economy.

But does the beautiful heavystar knockoff of the Leitz 12585 really vignette???

I used a heavy star straight sided 40.5mm hood on my J-3 when I had one and I don't recall that I had any vignetting trouble. I am now using a 1950's vintage Voigtlander hood that might work well with the J-3:

I no longer have a J-3 but use it on my J-8. Actually on all my 50mm lenses with 40.5mm threads.

Some pictures have come this way, with hood and yellow filter. I think this is vignetting in the corners:

I will try an Heavy star straight sided 40.5...
Thanks!

I have a B&W filter on my J8 and J3 and the Leitz Summicron barn door hood grips onto that rather tight. Still allows for the aperture ring to be set without removing it, its very large but has a see-through part so minimal block of the viewfinder. Looks very classic on the camera too
 
Thanks for your advices. The strange thing is that that lens hood Heavy star make problem only on the J-3 and not on J-8. Same Heavy star with the diameter 39 works fine on the Color Skopar 35 mm...
 
The front lens is bigger on J3 than on J8, so offcourse. But I've never seen that effect on my J3, although I shot thousands of frames with it.
 
I use a 40.5mm screw in hood made for the Nikkorex 35/2. At least one thing was useful from the Fixed-Lens Nikkorex SLR line! I always keep a filter on the lens as well. I picked up a lot of Schneider MC filters from Popflash.

With the 1956 KMZ J-3 stopped down:

Thanks again for your information.s I still do not understand: this photo was taken the same day, always with filter and lens hood, but there is no vignetting ...

Vignetting is also affected by of F-Stop and Distance. Wide-open and infinity focus will be the worst case. At close focus, the focal length of a lens is effectively longer, and less vignetting occurs.
 
Yes, I will try to do some shots without hood. I hope this is only a problem of vignetting, which can be solved by an appropriate lens hood, and not a problem of this lens.
 
The rectangular plastic push-on hood is cheap and effective: but it falls off when bumped even lightly.

As Santafecino says above, vignetting is worst at infinity and small aperture. This has been my experience too.

I recommend the small wide angle hoods from heavystar, like 200415316205@ebay. Does not intrude in viewfinder, does not vignette with filter, and gives enough protection.

Vignetting is worst at infinity and closed down, at least to f5.6 or higher.
