This is exactly what I was looking for. The only thing can't seem to find the adapter ring without glass in it. Would you have a link where I could find that?
I used an inexpensive UV filter and just a small strip of electrical tape to attach the glass. UV filters are widely available at any size. You may even have one in the attic of a family members house that did film photography.
I just came across your video, and I’m fascinated by the results. It’s absolutely beautiful-congratulations! I have the two Minolta lenses you tested. Do you think this experiment could work with a Canon 5D? Thank you !
It should. If you have any friends and family with prescription glasses (unable to see far away), you can try and test by holding them in front of the lens to see if it gets you closer to infinity focus. It is obviously a little bit of trial and error. My brother joked that I should take my camera to the optometrist, which to be honest would actually get you the best result with each lens if they are open to helping you.
@@Tensai0 You will want to pay attention to the filter size of whatever lens you want to do this experiment. The Minolta lens I first tried this on has a filter size of 50mm, so I got a 50mm set of science lenses. I later tried it on a lens that has a 58mm filter size using a step down ring, and it still worked just fine.
I tried some experiments a 135mm f2.8 lens and managed to get one to work. However the images were soft at infinity focus. When it comes to telephoto lenses I think it is more challenging for this to work. It is possible with the right focal lengths but may require some experimentations. The results may not be worth the effort.
That should work, but I think it would slightly reduce the effective f stop of the lens by a small percentage. Ideally you want a step down ring to prevent applying tape directly to your lens. It is easier to damage a ring than your lens. Also be aware that different focal lengths may require different strengths of a double concave lens. So some experimentation is required if you want infinite focus. A telephoto lens may only focus to infinity if the double concave lens is mounted far away from the front element if it is not strong enough. Macro focusing should still be achievable. Just get a cheap set of double concave lenses to try it out and see what works before finding an expensive set (small ones will work but lower the f-stop for learning what focal distance of the double concave lens works best). I almost wanted to buy a set of cheap lenses used by an optometrist to do further experimentation with this!
Unique look and I like the results! That image at 6:50, pure art.
Much appreciated!
indeed!!!
The photos and videos from the minolta lens looks like a dream 🥺
very interesting results !
Thanks for taking a look!
lucky to see you here wow!

can you give me the link to order one?
The science lenses I ordered using www.amazon.com/gp/product/B07Z3CVFMB/ and I taped it to a UV filter with electrical tape.

Thank you!
is there any size you advise me to buy?

Hi i have Minolta mc rokkor 200 mm ,will achromat doublet
lens 62 mm help to correct the infinity focus problem.

@@thefunofphotography Thank you
Do you think I can just tape the 75mm glass onto a 77 or 72 step down ring without a lens filter ?

@@thefunofphotography thank you for helping me. I loved the photos you took with this set.
