lens hood for 5cm 1.5

The CQ hoods do come in 40.5mm, I think. The good thing about them is you can get them with a nice push on cap, so you never have to remove the hood.
I believe they're similar to the CV hood/cap that originally came with the 35/2.5 P I Skopar. That one was 43mm screw-in, and I use it on my 35/2 UC-Hex and 50/1.4 Nikkor S.C.

I also have a Heavystar 40.5mm screw-in that I use on my Nikkor 50/2 H.C (the one I got from you, Raid. 🙂). On that one, a Leica e46 snap-cap fits.

I haven't tried it (I will when I get home tonight), but I suspect that a vintage Canon RF hood with a 42mm adapter would fit. The Canon lenses have a 40mm filter ring, but I bet it's fine. The nice thing about the Canon hoods is that you can get them with a clamp-on adapter, rather than push-on, so you won't lose it again. Also the hood/adapter usually takes a Series VI filter. KEH has a couple (both the square and round variety), but they don't seem to have any with the clamp-on adapter (only push-on). Pacific Rim has a square one with push-on and a round one with clamp-on. CameraWest has couple, but it's not clear from their listing which adapter type. You could also contact Jiri_e (eBay seller) who often has a bunch of Canon RF lenses and accessories to sell.

Thanks for tips, Ari. I hope that you are enjoying using the Nikkor lens. One day, I will get such a lens again.

I am enjoying it, thanks! I've used it for some of my favorite photos of my younger daughter (for some reason the lens has a particular affinity for her...) Alas, it doesn't get used as much as it deserves these days, due to my truly appalling case of too-many-50s syndrome.

I wonder if the square 42mm clamp-on shade for old Mamiya TLR would work too?

Never ever use any square or rectangular lens hood with a vintage Sonnar : the lens is not rectilinear guided when you focus, and the front element rotates. A square or rectangular hood would have its flat sides getting into the lens field of view every quarter of lens element turn.

So, conic (normal or tilted, whatever works) or cylindric shaped hoods only with that lens (and any other similar).

Excellent quality (vintage or recent generic) 40.5mm screw-in hoods are very easy to get, no needs to make the deal more complicated by wanting to use a 42mm push-on or clamp-on hood there IMO.
 
You're correct re: the 50s on the Contax & Nikon RFs, but I'm pretty sure the front elements on the LTM versions of the 5cm/1.5 Sonnar (CZJ, Jupiter, & Canon) don't rotate.

As far as tilted/angled v. straight vented hoods, I've found the tilted/angled version (styled after the Leitz 12504 & similar hoods) work better on cameras w/framelines where the VF/RF is a little higher up, e.g., M series Leicas & later Canon & Nikon RFs, whereas the straight ones work fine on Barnack-style bodies or the Contax RFs.

My (lost) lens hood was squarish, and I have never experienced any vignetting with it on the CZJ 5cm 1.5 or 5cm 2.0 or the J-3 or J-8.
 
I found an SW made 40.5 lens hood [cheaper then HeavyStar) which screws into the front very tightly.

What a relief.

Hmm, but in principle Highway 61 is right. If the square hood never intruded on your FOV, it means it wasn't doing the optimum shielding. For a given lens with rotating front, a round hood shields tighter before you see vignetting than a square one.

... assuming that the front is rotating. Is it?

So it's not rotating, 'course.

But since your OP was in the Zeiss Contax forum not in the FSU one, many of us probably assumed you were talking about an original (Contax mount, unmodified) CZJ 50/1.5.

So you got one of those fairly easy to grab Chinese 40.5mm screw-in hoods eventually, and it screws into the lens front very tightly ? How strange if you consider that your lens has 40.5mm threads.
 
The Moderator Brian adapted CSJ LTM has a very thin front edge from the J-3 barrel so that not all type of lens hoods will firmly stay in palce.I have the Canon lens hood for the 50/2.8 with the screw to tighten the fit, but the edge is too thin.
 
In that case get a cheap 40.5mm filter, remove the glass from it, screw the bare filter ring firmly and once for all onto your Sonnupiter front threads, and then you're done for using any type of fully versatile push-on or clamp-on hood you might want to.
