During your career you have shot film, but maybe it wasn’t primarily in B&W landscape. Color filters gave photographers the power to adjust B&W image tonal relationships while out in the field that ...

Have you tried the Night AR mode? I’m not sure how Googling and writing down could compete.

Does amp glow exist on the 50 S-ii, for yet more wax?

Intensity x Area = Total

Well considered. I’d go for that 135, and the superb 105 MC is often quite short in practice. A point I’d add to #1 though, after two solid weeks of hand holding  the Z9 + 500 PF, is that one tends ...

The Sony GM with that spec is quite nice optically. Unfortunately operating it via the Techart adapter was frustrating in the extreme when AF was called for.

I was pointing out a way to become aware that some MF shooters do indeed use T/S equipment. I’ve never calculated the percentage but there is typically one or more threads on the first page. It’s ...

I have often focused on 1st magnitude stars with a 20mm/1.8 on my Z7 with no special settings other than max magnification in the viewfinder. The vastly larger entrance pupil on your C6 should ...

It’s discussed fairly often in the medium format forum.

Elaborating on that: For any given print size the lesser magnification of a larger capture area is a point in its favor. Diffraction scales with magnification ratio. I have found that contact ...

Don’t count it out if you have ever experienced aliasing… which you almost certainly have even if you haven’t noticed it yet. “Diffraction limited” can be a very good thing when you have fully ...

Yes indeed, But caveat emptor, many of those filters are long lost.

I’d definitely want one if I was shooting chrome film in a Fuji 6x17, otherwise I never think about it.

The camera companies have both kinds of the hammers discussed here (speaking broadly about coatings equipment)… my preference would be for the one that completes it’s job more quickly.

When you increase exposure to get the corners right, the center will be right there with them and the noise will be good overall for the first time.

I would have expected that there would be a vacuum sputtering deposition process onto an optical flat (I’ve done that onto various substrates with gold and aluminum, which is simple so far), with ...

Those powerful LED flashlights have 100 individual LEDs in a disc about 5 cm across. I laid it directly onto the lens so the array of LEDs made an array of bleaching spots on the lens.

Interestingly, the yellowing can be reversed via a great deal of UV irradiation. After burning out a 100 uv-led flashlight I continued with good old sunlight. However I still didn’t get very far ...

Back when Edmund’s catalogs were printed at about 5”x7” and were still moving a lot of WW-II military surplus optical gear I think they had some aerial reconnaissance lenses that covered the small ...

Security is a consideration with any computer open to an outside connection, so I see the relevance. But that wasn’t my question, I’m curious if the included Windows feature can get the OP’s ...
