This article presents the inventive solutions Canon has found to shoot beams of light into the camera's viewfinder in order to light up individual autofocus points. Six different approaches are shown using six Canon DSLR models between 1994 and 2009.
It's absolutely wild to me that this function would be so important as to justify all the time and effort to create not just two, but six entirely different ways of solving it.
The first one seemed perfectly adequate to me. But I guess that's why I'm not a Canon engineer.
Huh, that definitely explains it. I wonder how many people know that. In that case it's particularly unfortunate to downvote the OP simply for filling a field in the submission form! Sigh… I guess it's another case of LLMs having made the world a little worse for everybody.
Yeah, but before LLMs we didn't have "reads like LLM output" as a downvote reason. In 2022 nobody would've had qualms with the phrasing of the comment.
But the articles are well-researched, very high quality (the illustrations in particular are incredible), and in every way prime HN material, and there's no money involved as far as I can see. I definitely don't have any qualms about self-promotion of this sort of stuff.
You can get a Canon 5D II or a Canon 6D for that. Older cameras for sure, but full frame with excellent sensors. And there are a ton of inexpensive used EF lenses available.
Compared to moderns systems the main difference is the autofocus and video capabilities. Modern mirrorless have cosmically better tracking, eye detect etc.
To add: Hit https://en.wikipedia.org/wiki/Canon_EOS_5D_Mark_II and scroll down to the very end, then click "show" to expand the "Canon EOS digital SLR timeline". This is an incredible collection of information that I can't figure out how to link directly.

Personally, I’ve only ever provided a summary if I felt the headline wasn’t clear enough.

Not sure why it is a "template".
