p.1 #11910 VPK Meniscus conversion...
Ok, here is another one of my crazy projects. I am converting a popular version of a WW I camera, often used by the troops, namely a Vest Pocket Autograph, made by Kodak very early in the 20th century.
I am not the first guy to come up with this idea and there are several approaches to this theme.
The VPK series of cameras were made in great numbers and were reasonably affordable back then. The early ones had a ball bearing shutter with a primitive meniscus lens BEHIND the shutter. The better models had improved optics in front of the shutter. Those "in the know" look for the older meniscus lenses. These produce soft but totally charming images. I paid $29 for this nice looking sample which included shipping.
Some devotees will take the entire camera and mount it onto a M42 extension tube ring and then adapt the ring to a modern DSLR. Others remove the lens from the entire shutter mechanism and mount that into some gizmo. Removing the lens from the camera exposes the entire lens which is around f/6 or something. When the lens is mounted in its stock shutter the bayonet uses the center of the lens and reduces its speed to f/11. I want all of that glass working for me though.
So far I have carefully removed the lens without harming this great looking little camera. I then removed the lenses from a cheap enlarging lens I had lying around. The old meniscus lens fits in the enlarging lens body nicely. The tricky part is deciding how to take care of focusing? I can use a series of extension tubes, a macro focus rail or some kind of helicoid focus ring? I would prefer to have the greatest flexibility when it comes to focusing so I vote no on the extension tube rings option. I would prefer not to use a macro bellows. This means find some rotating helicoid system. Checking eBay I see that prices start at about $80 and up for M42 focusing helicoids. I plan on visiting my local camera repair shop with the hope I can find some junky M42 135mm lens for cheap. I could then remove all the glass elements and use the lens focusing helicoid to mount & focus the old VPC meniscus.
Here is the camera with its built in stand.
You can see the small "pocket" size here. Note the camera used 127 film and not the 35mm film shown here. There is one company in eastern Europe that still makes 127 film.
There were several versions of the VPK. The Autograph model came with this window and a "pen" stylus mounted on the back. Users could then write their name or a short message by pressing on the film's backing paper which would show on the edge of the developed photograph. This was an effective sales tools for service men serving oversees, etc. This camera became known as the "soldiers camera". Pretty cool, no? I wonder what images my camera has taken over the years?
Here is the lens and shutter removed from the camera. You can get a sense of scale when its posed with my 58/1.2 Rokkor.
Here is the front of the lens with all its retro focusing and composition guides.
Here is the back of the lens with a US penny.
I went over to my friend's camera repair shop and found a broken 5CM Yashica lens in the M42 mount for next to nothing.
I took the lens totally apart and abandoned all the glass elements. Between all the old lenses I have dismantled recently I now have a growing collection of threaded rings. After playing around with all the various bits and pieces it suddenly came together. I now have the little meniscus lens element mounted in this old Yashica lens housing. Even all the front Yashica lens rings are in place. I think a longer donor lens mount would have worked better though as I need my Canon EF12 Extension Tube to get some kind of normal focus going. It still needs a little more extension. I might buy a cheap set of M42 extension tubes as well. These are dirt cheap. The right length tube should get me in the zone and the Yashica focus barrel should then provide the "fine tuning".
What should I get after all this? That is a good question. It looks like I will get really soft images that are hard to focus. But what I have read it takes some practice and work before this becomes more natural. I think this crazy old lens might be appropriate for some stills photo subjects. Might be worth trying for video as well.
I had some errands to do today. I picked up an old set of three metal M42 extension tubes. The middle one is perfect with my fabricated meniscus mount (the Yashica lens). The tube gets me "there" and the focus action on the Yashica lens mount does the rest. Finally! I took a nice walk and shot a few test shots in Seattle this afternoon.
This meniscus lens is SOFT and it flares like crazy. But I love the character. Its like nothing I have tried before.
I am not sure how you guys will like this lens? Usually the quest is all about sharpness, clarity and accurate focus. This lens is counter all that and more. Its not perfect for all subject matter but going "soft" is kind of fun in its own way.
Enjoy…
And after a nice walk taking pictures there is always the reward…
Let me know if you guys like these?
Cheers!

I like it!
Very cool!
I would like to get into this kind of stuff.

vintage look, perhaps also romantic, might be good also in B&W,

You still need 1 more picture, the finished product.
I'm curious how well it will handle portraits.
Thanks for sharing.
My early version Super-Tak 28 has some of that feeling wide open,
the flare is better controlled and quite nice, and is of course much sharper than your VPK. It has become one of my favorite lenses because of this feeling.

Here is the "finished" lens.
You can see the old VPK meniscus lens (the brass ring and glass) inside the center of the donor Yashica lens housing. I removed all of the Yashica glass elements but managed to keep most of the housing and lens aperture blade system. I can sort of activate the aperture blades on the Yashica behind the VPK meniscus lens for better stopped down "performance"... but I like the glow with this lens wide open...
Behind the Yashica is a metal M42 extension tube that is mounted onto a M42 to EOS adaptor. I bought three tubes today. The middle one is perfect for most use. The longer tube is the ticket for closer work...

Nice job!
I'd Black out the name ring as a finishing touch.

Nice story, a 100 year old lens on a digital camera. I like the 3 shoe photo.

This is completely awesome. very nice job on adapting it. lets see some black and white shots. Also have you tried shooting any video?

Hmmm....I particularly like the last few images, thank you for posting this.

Great job on a creative conversion! I especially like the photos with the wine bottle bottoms, the fruit/veggie display, and the upside-down bar stools; this is definitely a very "alt" alt lens, and gives a wonderful surreal look to photos. Perhaps if you could find some veterans (or their children/grandchildren to match the WWI provenance) with vintage uniforms, a series of black and white portraits would make a really awesome and touching project.

Thanks All,
I had a great time thinking about and doing this. At first I was sort of crestfallen after the first try with the Canon EF12 tube as it looked like I would not be able to focus this system that well. But the slightly longer middle of the three M42 tubes got me right in the ballpark. This meniscus lens is a lot of fun just to look through. When I picked up the tubes I also grabbed a couple of free filters as well. I used a rough looking Cokin A124 sunset grad filter on a few of these shots.
But this lens really does call out for black and white images though. I am quite psyched to try out different things. This will have to wait until next week though...

Wow. Would love to see black and white images from that lens. A portrait in particular.

Did someone say spherical aberration?
Be sure to post some portraits taken with the lens, I'm sure it'll look great!

Excellent project, story, and final photos! I love the color.
I may have missed it if you already mentioned it (I apologize), but the lens is being shot wide open, with the aperture disabled? If so, it's a shame, as that looks like a nice aperture blade opening.
I'm curious if there are threads on how to front-mount folding camera lenses, to retain the shutter and aperture function. I have a nice post-WWII Franka 6x6 120 folder with a beautiful Schneider Radionar 80mm f/2.9 coated lens I'd like to use on a Canon EOS mount. Mainly I want to use the aperture, but the shutter would be a bonus! Anyone have a suggestion where to look for this sort of thing?
