Nikon SP holder for eyecorrection

[Alpsman]

With this mount for the Nikon SP rangefinder camera, an eye correction lens from a cheap pair of reading glasses can be attached in front of the eyepiece so that the viewfinder image appears sharp again.

Thanks for this--now I just have to find someone with a 3D printer!

Many private owners of 3-D printers keep it a secret that they own one, because otherwise they would have too many "friends" too quickly.

There are many service providers who can print this.

Could you list a couple?

I use a small shop called panashape, they do SLS (selective laser sintering.) This design should work well with that tech.

They are about $15 for 1 piece, including a setup charge. Price drops to about $4 each with quantity. This is for the standard quality, other options increase the price.

Here is what an SLS print looks like:

If you're here in the States, many local libraries now have 3D printers that library members can use for a small fee.

Best,

I'm already thinking about putting an accessory shoe on it, but I don't yet know how to design the clamping so that the - usually expensive - viewfinder doesn't fall off.

Luckily with SPs there isn't much reason to use an aux viewfinder. 🙂

Yes yes, I know.
The SP just stands apart from the mortile rest.

But apart from the fact that that is not the point, it is about the fact that there is an accessory shoe on top - perhaps you want to mount a flash - a viewfinder is very helpful for the 12mm Voigtländer, for example.

It is not a question of whether we need it, it is a question of whether we have it 😉

By the way: THANX for the pix & your feedback 👍😉

I just received my SP eye correction holder and it fits the accessory shoe perfectly. Do you have any hints on how to cut the plastic lenses from a pair of reading glasses? I tried a shop knife with a fresh blade and an Exacto #1 blade and neither one seems to make much of an impression on the plastic. Thanks for any suggestions.

For the rectangular lens for the SP-holder i used a mini hacksaw like this
slow and gentle so ya dont slip and scratch the glass.
You can use a piece of cardboard as a ruler.

For the round lens for the S2 holder i used a Dremel with a circular saw blade.
For the finishing fit I used a file.

Attention!! coat the lens with some tape do ya don't scratch it accidentally. See / read instructions at printables.

I also suggest to melt the edges on at least three spots with a hot screwdriver because when you need to exchange the lens, it is easier than if it is glued in.

Happy shooting 😎

Thanks for the info--I will have to try this.

If you use a Dremel with a circular sawblade also - slow and gentle.
To high rpm will melt the plastic of the lens.

I finally got the reading glass lens cut out and mounted on my SP. It is great to be able to see the 50 mm frame lines and a clear focusing spot!

Thank you for your feedback!
May your vision always be clear and, above all, sharp ;-)

Thanks for creating the 3D program for this--it makes this camera much more usable for anyone who needs glasses.

Man, I miss my SP and all those great lenses.

One disadvantage still remains. While you can see through the viewfinder without glasses, the numbers on the lens aperture ring and the shutter speed dial are blurry without glasses. :-(

If you construct an additional correction lens holder for the aperture ring and shutter speed dial, this "thing" becomes a bit unwieldy.
. . . .
But you can't have everything.

Maybe use contact lenses?

It is a shame.
My SP is older than me and still works without squeaking and still can see sharp ;-)
Some things you really should take to your grave.
