Reasonable advice... although the "Don’t spend too much money just yet" part needs a lot of perspective. First off, film is NOT a cheap medium; you could consider a typical $25 compact 135-film...

There are a lot of SEP (standard engineering practice) things that people have managed to get through the US Patent Office. From what I've seen, usually there is some tiny thing different from...

That's not the point. I've served as an expert witness in some patent cases, and I've NEVER seen the defense go for invalidating the patent (even when I suggested they should). It's simply a...

Wow. It is very unusual for a granted patent to be declared invalid -- the usual defense is that it doesn't apply in the particular case cited. This says something bad about Autel and scary about...

Can probably run Casio's software under wine....

MrBrightSide: As a professor, I had a week (Spring break) to go from regular lectures to fully online course delivery from my home. Most of that time was spent dealing with course infrastructure,...

Not even close to hitting the same market. It would be like saying the RX100V is junk because it can't compete with the A7RIII -- they're both capable stills cameras, but not really used for the...

Inspired by the Adorama contest, I figured I'd try capturing some images around my house with unusual perspectives using equipment I haven't used for a while.... First, using a tilt adapter on my ...

5 minutes max clip time unless you "disable the overheat shutdown function"?

Everything else here sounds just like I'd expect, but the overheat shutdown is generally to prevent damage to the...

By type gets a bit complex because lenses of the same type aren't actually the exact same formula.... Also, type isn't really widely advertised for most lenses, so it's a matter of guessing or ...

The iris in the adapter is rarely in a position that works as an aperture stop -- instead, it will vignette on many lenses. In fact, if you want a lens-external aperture, it's more likely to work ...

My first Casio was a QV100. Excellent camera for the time, and truly designed as a digital camera, not as simulating a film camera or a camcorder. Unfortunate it used those odd .cam files instead...

Not necessarily very useful, but all good hacks. Makes me wish I had such a conveniently-shaped egg timer.... ;-)

MTFMapper has gotten a lot more sophisticated since I last used it for a multitude of lens tests (back in Fall 2015). I will say that alignment is always a huge pain (and usually is poorer than ...

Yes, PLA is a plastic -- and notoriously immune to most solvents, so it's difficult to have paint bond well with it. You might have problems with polished metals, but Black 2.0 is a " super flat, ...

Interesting. BTW, that seems to contradict the mhohner reference above: " An xi series (or later) body is required to use these lenses. However, the auto-zoom feature is no longer supported by ...

Yes, all the big changes were before Minolta gave Sony the line. However, there have apparently been a number of minor protocol tweaks since then, as well as changes in the power provided, and the ...

Yes; it works directly on most surfaces, even including 3D-printed PLA (which is what I use it most for -- making colored PLA custom adapters light tight).

Alpha, Sony A, or Minolta A or AF (MAF) all refer to the same physical mount... although Sony's use of "Alpha" or "A" in naming some E/FE mount bodies is a bit confusing (they have a different ...

I used to use flat black latex wall paint -- dirt cheap after Halloween.  :-) However, I've been using Black 2.0 for years now, and it's better. Oddly, it doesn't really look as black as some ...
