My journey into stereo photography stared with my old Optio 230. That had a built in chacha setting to make a stereogram, and I have some fun pictures of my daughters. Barbie getting her hair don’t by Bob the builder. 18 years after, I have the stereogram attachment for a 50mm lens and tried it a number of times. I struggle with getting the images to work well. I also don’t like the fuzzy centre like. I am wondering if there are any folk that use this a bunch and might have some “important to remember” advice.

The only things I used to do were a) make sure that the screw-in attachment was level, b) be really careful with focus as the line between the two images went through the split image focusing aid, and c) use an aperture of I think it was f5.6. I seem to remember (haven’t seen or used mine for many years) that this aperture was specified to prevent the images blurring together in the centre at wider apertures, and the centre black line being too thick at smaller ones.

Manual says it is designed to be used with 50/55mm lenses. Shooting should be at f5.6 or 8. You may want to experiment with using a 35mm focal length lens works better on a crop sensor.

I am using a k1 with a 50mm f1.7 prime. And thanks for the link

Some success!
Focus is so critical as is making sure all things are properly aligned.

They work really well with the O-3DV1

Oh, nice with good separation for the 3D effect. Too bad the area of the combined image is rather small but there's a price to pay for convenience.

Nice! With a little bit of squinting, you don't even need a viewer!
