In the end these are designed as a system to meet a cost vs performance objective. So you are asking the wrong question, per se. Geometric distortion, chromatic aberration, resolution, ...

You can do 1:1 macro with that setup without any accessories. With internal focus, i.e. modern lenses, the result of using extension tubes can be not great, as the spacing of the fixed rear ...

In my case the straws would need to be about 1mm in diameter, but essentially that is what I was thinking also. I have some experimenting to do this weekend.

I just use continuous shooting. Most handheld wired remotes for Pentax include a "bulb" mode which holds the shutter button. The K-1 will run for about 3+ hours off a fully charged set of OEM ...

I got a little lost with the translation stage bit, so essentially you are moving the target in the Z axis and looking for magnification changes front or back focused? I mean that sounds pretty ...

That citation you quoted is from Wikipedia ( https://en.wikipedia.org/w/index.php?title=Perspective_distortion_(photography)&oldformat=true#Telephoto_perspective_distortion ) and the link in the ...

I guess it cannot find ... that articles?

I suspect the lights are actually individual LED emitters spaced apart, and you are only seeing the spacing because the reflection is less exposed. Take another shot which is underexposed and ...

I'm trying to solve a problem with actual lenses, so this is more of a practical than theoretical question. I have a long distance microscope positioned some distance from a subject - inches / ...

Objectively there is a lens focal length + print size + viewing distance tuple that provides "normal" perspective. But as you say, unless one is forced to view the print in some standard way, you ...

You raise an important point regarding biases in how average people are depicted or not depicted in media. What you are observing is just poor photography. Decades ago when I did portrait ...

Can you imagine the disappointment of getting that call? "Congratulations, it is my pleasure to inform you that your have been awarded the Alfred Noble Prize for Civil Engineering." Wow, I didn't ...

I'm just a customer - one still waiting for things I ordered a year ago - and seeing 2x and 3x price increases on new orders - so the internals of what you are dealing with are of great ...

Ugh, I misspoke. Dyslexia, I don't recommend it. I had intended to say that a higher resolution capture of a poorly performing lens would be better than a low resolution capture of a high ...

A different take: So after my mom "passed" we were looking for photos. My uncle - the technophile with his rediculously expensive early digital cameras - had kept every shot he ever took ...
-
Ultimately you know how it was before and after - so if its not right after repair, I would open a ticket with Pentax support and explain that you want a different lens if their factory authorized ...

I have shot about 8M time lapse stills, one camera had millions of shots and Fuji replaced it or free well out of warranty to see the wear. I still have another fuji with 2.1M shots on it, and...

I'm holding out for the eye-roll emoji edition using only the finest emoji-skin and real emoji eyes, hand stitched by world famous emoji-wranglers.

"All this and more" you can determine on your own. Some FF cameras and other cameras include cropped RAW output. So you have two files that only differ by the number of pixels with ...

He explicitly states: "For example, I strongly recommend a 70-200 f/2.8 zoom lens for portraits." ( Emphasis, mine. )
