round Leitz hoods with rectangular fronts, howto DIY?

Wow, this is really cool!
Would it be possible to add some pictures taken through the viewfinder to get an idea about how much your hoods intrude into the framelines?
 
...And I see you set up shop already!

Good luck on the sales!

Devil's advocate: You think you could do film holders for the future Plustek 120 fixed-focus scanner, in different depths? So there's always a film holder available that'll achieve perfect focus when using that scanner (once it finally ships...)?🙄
 
I don't see any reason why not?

I don't know what the issues are, but you could probably design an adjustable one - i'd imagine an outer frame, with a sliding inner section that holds the film. There would be a series of steps up and down, or even a diagonal slider?
 
Cris. I see you cv21 is the newer M mount version. Do you know if the hood size would be the same on the ltm version?
Thanks
 
The untested version of the 35/1.4 arrived today. The build quality and feel impresses me. It definitely is a nice setup.

I shoot film only so I can't test it immediately but looking through the film gate with the back off of the camera, I can definitely see the hood. It looks like it may vignette to the same degree as a HeavyStar hood does when used with a filter. Very minor detail, but the hood also rotates maybe half a degree too far when mounting. This may be manufacturing variation in either the mount/hood/lens/etc though and is easy to deal with. I'm 95% sure a cropped sensor body wouldn't have a problem with it.

Based on the build quality, I'd definitely buy another once any vignetting that is there is sorted out.
 
Hi there Brian,

I'm glad you're pleased with it so far. It does rotate a little further, that's to allow for any issues with the printing as i figured it was better to go a little further than be 1 degree short. I'll be adding a mark on the top of the hood to align with the aperture mark for easier alignment, as i too found similar trickiness getting it just right when my test ones arrived yesterday.

Please let me know about any vignetting and i'll make adjustments if need be. Thanks!

I've designed for the 21mm Color Skopar, not the Snapshot, i have no idea at all what the difference between them is i'm afraid.

Cris - is that the screw-mount version or the M-mount version?

EDIT: on the linked page Stephen Gandy states "The optional square LH-1 lens hood will fit the 21P, but the LH-1 is not suitable for the R4's as it blocks too much of the viewfinder." So the answer to Nick's question looks like - yes they are the same.

Hood for Leica 35 Summilux Pre-Asph ver II with filter

Hi ChrisR, any chances you will be able to make a hood for the Leica 35 Summilux Pre-Asph ver II with a filter slot? I believe many users here will be eternally grateful, myself included 🙂

I've done it for the M mount 21P and 25P lenses.

Given how oversized the LH-1 is, it probably doesn't matter if the lenses are fairly different, and given how specific my fitment is and how close the geometry is, i certainly wouldn't tell people they are the same. As little as 1mm shorter and you'd get overlap into the FOV.

Thanks ChrisN. I didn't notice that when I read about the Voigtlander hood. I am going to take a chance on ordering one of Cris' hoods when they come available.
