question:

I've been reading here and there
that it is possible to use switar RX lenses
on nonreflex cameras, if they are over 50mm.

In my case I am particularly wondering about
using them on an Eclair ACL.

Has anyone had good results with this?
Is there a compromise in picture quality?

Seems like if you're wanting to keep the glass small
and relatively inexpensive, that the switar AR lenses are a good option.
Yet, most of these are very old and not as sharp as the newer
switar macro lenses?

any input would be most appreciated.
thanks.

whooops.
just now saw the pdf on the preceeding zeiss lens post.
which more or less explained what I was wondering.

Still though, curious if any acl shooters bother with the rx switars?

thanks.

o.k.
Am I very confused,
or is this seller way off mark...

They just wrote to me regarding a
Bolex Kern Macro-Switar 26mm f1.1 RX Lens:

"The 26mm f1.1 lens should be ok for standard 16mm or super 16mm for your Eclair acl. Rx lenses are needed for Your Eclair."

I have never heard that The Acl needed RX lenses.
Did I miss something along the way?

The seller is spouting some bovine excrement.

You'll find that the Switars above 50mm aren't even marked as RX ... ie. they are just 16mm lenses ...

The 50mm I think were branded RX though, maybe to force peoples hands into not considering other brands ?

I'm pretty sure the same rule fro using nonRX on RX cams applies in reverse ... Just stop it down a bit
