Very well stated. There are many historical photos taken with lenses that fell far short of current technology. Some with primitive optics. I might not envy a primitive lens as much as someone's ...

Nice Agfa results! Fork is ominous.

Thanks...I usually assume I.am the only one awake at the end of one of my bouts of keyboard dysentery...on a phone, no less.

Adapting shutter external threads to M42: I found M25x0.5 is external rear thread for three Compur shutters holding lenses like S-K Xenon, Rodenstock Heligon & Steinheil Cassar (S). I got a ...

I'll try almost anything, which involves using lenses for applications they weren't intended for. Then I post-process. Some lenses I haven't cared for, on one camera format, I liked later on a ...

NEX-7 Eiki Kowa Super Prominar 16 (black) film projector lens (very short FFD). One disadvantage of film projector lenses is they have no specified FFD (that I know of)...the film distance can be ...

Steinheil made some respectable optics. I have never seen a Schneider-Gottingen lens, but heard they made more military optics than S-Kreuznach. For anyone unfamiliar, German and possibly other ...

I have one last 50/1.9 S-K Retina Xenon, actually my first, & still have the import certificate (s/n confirms that). I sold the camera & other lenses. I kept this lens because it's got enough ...

Now I understand why I had so many questions, after reading some Nikon & Edmund Optics pages. Maybe this will be of interest to others: https://www.edmundoptics.com.sg/knowledge-center/application- ...

Possibly. Many death records go public after 50 years. My daughter found things I didn't think were findable on Ancestry.com, but it helps to be able to cross-check relevant from irrelevant info. T ...

Very nice. Type 246 is an interesting camera. Nice Flickr library...I got lost in it for nearly an hour.

Thank you, River'... The scopes are both stereo zoom binocular types on heavy boom stands. One is 0.3-4x in the scope head. Both have WF eyepieces that are 10x or 20x. I don't know the terminology ...

Can someone please clarify whether a typical US$15-20 microscope-NEX adapter is sufficient to get images from a microscope into a NEX-7? A $20 experiment is worth exploring. I have a couple ...

Ooh, I just realized this thread started in 2015. & Some days I read MF to mean Manual Focus and other days to mean Medium Format. I might be answering a question that wasn't asked. But I received ...

If they focus an image, they deserve some exploration. I am accustomed to only finding macro ability with hasty adaptations. :@)

'Should', in principle, if they fit. Manual, as you know. Have to try & find out if there are any vignetting or other surprises. I'm not familiar with the camera to know if it needs a menu setting ...

I wasn't looking for this. I never heard of it 3 weeks ago. I won a relisted (winner didn't pay) Kodak Retina II incorrectly described as Retina Xenon. As-is, for parts or repair. It arrived & did ...

When I buy adapters, I know I am getting coupling and spacing. That's usually enough for Franken-mounted lenses I'm repurposing/misusing. My view is that most (but not all) adaptation is ...

From one of the early replies, I got the idea one needs additional optics when replacing a microscope eyepiece (ocular?) with a camera adapter. The illustration showing a projection accessory ...

I have a couple OLD stereo zoom microscopes with the smaller eyepiece size...23.2 mm (newer are usually 30 or 30.5 mm diameter). Since they replace one of the eyepieces, I assume they have no lens ...
