Lens hood for Jupiter-3

[luiman]

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.

Yes, this is perhaps the definitive solution, I think. I've already ordered ... Thanks!

I have one of these vented hoods from heavystars that I sometimes use for my 40.5mm-thread lenses, though I have not noticed any vignetting with my Sonnars and variants. But then I rarely shoot them stopped down at infinity. It's all about the available darkness.

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

Probably different source of vignetting in my case. The vignetting inherent in the optical design of a lens is worse when used wide-open, but is still called vignetting. The 50mm f1 Noctilux is one example. I've never checked to see if vignetting is better or worse when used with an improper hood.

Also seems to me that the vignetting due to the drop in brightness at the edges of the fast lens is greater at wide-open and visible especially when photographing uniformly illuminated scenes (i.e. the sky). I just wanted to know if the vignetting in my pictures is optical or mechanical (ie, due to the hood).

Understood and agreed.

What I meant is that if a hood causes vignetting, it's more visible at larger f stops (due to DOF). Seen with Nikkor 50/1.4, Canon 50/1.2, etc.

Some lenses have quite strong "optical vignetting" (due to lack of better term, undersized entry/exit pupils ?) that shows without hood. Examples: Nokton 40/1.4, Nikkor 50/1.4, Noctilux, etc. Typically at shortest focal length (infinity) and wide open.

The impression persists that luiman opened this thread by speaking of vignetting caused by a lens hood.

Yes, it is. In a second step, the optical vignetting entered into the discussion, but I hope that in my case is an inappropriate lens hood and not a macro defect of J-3 ...

Ferider,

I just found this post and am looking for a hood for the J-3. The link does not exist anymore. Do you perhaps have a picture/new link of the hood mentioned?

Thanks,
Roel

This discussion is useful no matter whether it is optical vignetting or lens hood vignetting.

Roland: the ebay auction mentioned does not work.

Same problem with the Lomography Jupiter 3+

Same problem with the Lomography Jupiter 3+

I tried the typical "normal" lens vented hood, and noted vignetting from the hood + B&W MRC UV combination. It seems that the Jupiter may actually be 50mm instead of 52mm that the Leica lenses happen to be.

I bought instead a 40.5mm "wide angle lens hood" that is supposed to be OK for 35mm lenses, and it is vented. Several are available on ebay for about $5 from Asia. This is shallower, and it has not produced any cutoff in the corners from physical obstruction.

Due to the shallowness of the hood, the pinch type 40.5mm cap can be used on the lens.

I have an original FED hoods (rectangular with rounded corners), they are should fits good onto J-3 lens. Brand new, any quantity available...

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.

This is exactly the same hood I've received back in 1979, along with my grandfather's Contax-II outfit, still mounted on his 50/1,5 Sonnar.

I had a J-3 already and this lens hood did a perfect job on it too.

Of course, the original, USSR-made hoods would be -also philologically- the best choice.

The Voigtländer hood is not rare and usually is unexpensive.
