Which M42 Lens adapter is best? (with sample videos using both)

[@johnnyfrisco5354]

Thanks for this really helpful video… m42 lenses on my D40s are fun and quality…

[@LukeofAllTrades.]

Great! Glad you're enjoying them!

Nikon F flange to film plane is 46.5 mm, the m42 is 45.46mm you need to mount the lens 1.04 mm closer to the film to work properly. But with a mirror in the way, the pin sticking out and a lens opening about the same size that is not possible. Thus the lens addition to push out the focus plane of a M42 to over 46.5 mm will fix the focus problem The added mount treads was designed for the proper distance knowing most m42 have the A / M switch The cardboard was a good idea but you might want a dark color to prevent adding light refection.

Dobrze to pokazałeś ten adapter z soczewką nie naciska tego bolca od przesłony i nie możemy sterować przesłoną przez pierścień przesłony jak bolec nie naciska takiej dźwigni w obiektywie. Druga kwestia bardzo fajny miałeś ten drugi adapter. Ja mam problem z Heliosem jak go oddale adaprerem od aparatu to słabą ostrość daje. Znowu ten adapter z soczewką blokuje też ostrzenie do nieskończoności bo obiektyw niema się gdzie wsunąć podczas ostrzenia bo jest tam soczewka adaptera. I tak źle i tak źle najlepiej mieć te dwa adaptery.

Dziękuję za komentarz. Zgadzam się, posiadanie obu jest fajne!

I am having trouble finding adapters for my Pro Tessar lenses. Do they even exist? Is something like that even possible??

[@LukeofAllTrades.]

It's a good question, but unfortunately I don't know anything about Pro Tessar lenses. Good luck in your search!

M42 thread lenght did not alter ..Your new adapter is longer to make it focus at infinity with the new lens adapter.

[@LukeofAllTrades.]

Very likely it helps, not sure how much the lens in the adapter plays a role too. I would have to take the lens out to really know for sure, but I don't want to tear it up just to test.

there are m42 to Ni adapters with infinity glass on them on ali expresses, generic ones, and the picture is bad out of them. is this any better > ?>

[@LukeofAllTrades.]

I think they're pretty good, but a lot of it depends on the camera lens you're connecting it to. There's some comparison footage at the end of the video, you can see how it compares between the adapter without a lens, and the one with a lens in it.

@@LukeofAllTrades. 👍🏻. I will still give it a shot. I see one on Ali express. It's the same pixco m42-Ni

[@sigmagamer364]

​@@saadomar1101how can you assume something is bad without trying?The camera lens itself contains so many internal lenses already.
