Thanks for posting the link. Some valuable information, there.

OTOH, one of the first 'useful comments' that I read is simply a personal opinion, and one that I think is wrong. That is: "Do not modify your lenses! Your camera will be obsolete in two years - a lens will still be around in two generations!..." That's just plain nonsense. In some cases, it makes sense, and other cases, it does not.

Even IF the camera is obsolete in two years ... which is absolutely false ... it is very rare for a lens mount to become obsolete in two years. Not to say that the SOME mounts haven't gone by the wayside of current production, but mount obsolescence is something that occurs over a MUCH longer period of time than just a couple years.

But, if you've modified a non-production mount to a current production mount, then you've actually converted the "obsolete" mount into to something viable.

The comment is (imo) a hyperbolic statement to infer the value of glass vs. bodies. Granted, as technology marches on for bodies, the advances in two years see increases. But, the point of obsolescence being reached in two years is bizzarro (imo). Will today's "cutting edge" camera be yesterday's news in two years when a new "cutting edge" gizmo arrives. Sure, why not. But, that in no way renders the former camera obsolete.

As to the list ... a lot in there to digest.

I think it' more about respect for classic lenses. If you don't want as it is it someone else might. You wouldn't modify the Mona Lisa, apart from adding a moustache!

Wait, what ? Two generations ? My parents havent given me any lenses.

And modern lenses are usually not fully mechanical lenses, thus they dont survive the end of their mount.

For example, my Nikon F lenses ? You cannot focus the AF lenses manually, their focus throw is too short. You cannot focus the AF-S lenses manually, they have play in their manual focusing.

Canon EF is only worse, for they are usually focus by wire.

Newer systems like Fujifilm X and G, they are all focus by wire.

Oh, and my D750 is now 7 years old, I think.

I understand the sentiment of the classic, but that wasn't the argument presented in the comment. Instead, the argument presented was the obsolescence of bodies. If the issue was to have respect for the classic lens, then one could likewise make an argument that the regard for the classic character is high enough to warrant the conversion ... particularly, if it is to breathe new life into a "dead" (i.e. not current production) mount. Adapters are typically an option in many cases, too. But (wides in particular) a well engineered, dedicated mount should provide a preferable experience to the bring the most of the the well respected class glass.

Again, that's a debatable / subjective perspective, but ... camera two year obsolescence has zilch to do with anything, regarding lens conversion. Just a poorly presented argument to a comment that I'm not sure we can really know what the point was. I just think that suggesting two year camera obsolescence is sensational hyperbole.

I just want to point out that I have no interest in "fast" lenses and have put the link here for those who are or are just curious.

So do you think they air-lifted the 510/0.95 in and built the observatory around it?

I think EF is 'worse' in this situation, because they don't have a manual aperture control ring. OTOH, by far the majority of Canon EF lenses are not focus by wire.
