Sigma Support - Good for a Laugh

In the "please stop asking" column, I contacted Sigma to see if they had any information about the Sigma 500mm F8 mirror lens. Their response:
Jonathan,

Thank you for contacting Sigma USA. We are sorry, we no longer have parts, updates, firmware, manuals or information on that lens. That was an older film lens and is not designed to work on any modern cameras.
A simple "No" would have sufficed. :P

"No" would have been sufficient, but it would have been terribly rude. The answer you got seems perfectly reasonable.

It's pretty standard sounding reply.

I guess the response qualifies as information. Something tells me that "No" would not have been well received either. I would suggest the Wayback machine (archive.org) to see if they have Web resources for Sigma from when the lens was new, but it seems it dates back more than 40 years (1975). All that being said, Sigma UK does at least have a dedicated Web page for the lens...

Sigma 500mm F8 Mirror-Tele Launched 1975 - Sigma Imaging (UK) Ltd

...also...

Sigma-XQ Mirror Ultra-Telephoto 1:8 f=500mm

The public library may have Modern Photography and/or Popular Photography on microfiche from the mid-70s where one might find a review.

Try calling a car salesman about a 1978 Vega. The will likewise know nothing.

“Not designed to work on modern cameras” is literally true, but irrelevant. They do, of course, work with modern cameras, but the implicit message is to go and buy one of their current lenses. Of course, the author of this spendid missive possibly doesn’t know the Pentax K-mount “modern” cameras exist, either.

PS: “firmware” support for a film-era lens? Does that mean wearing gloves when you handle one?

Not as bad as a reply to a question I had sent to a software maker (for info) who responded that they didn't offer that software anymore (I knew that upfront) and to continue to use the old software would damage my computer. (Note: they didn't sell any of their "newer software" to me.)

Hence, the tongue in cheek reference to an Adam Sandler bit -

I had one of those,
used it with my MX & ME
Was pretty typical for a mirror, bad hot spot & donut highlights. Was a bear to get sharp images out of it, very touchy focus
Was T-mount, so it could mate to just about anything
Bought it used, and sold it a few years later for about the same, if i remember right.

Wish I could figure out how to focus it to infinity on my K-3.

Pretty sure mine focused past infinity, guessing someone had yours apart and did not get it back together right?

Was more than 30-years ago, so my memory is certainly not to be relied on.

I like the "not designed to be used on modern cameras" part. The author really doesn't know us Pentaxians, do they?

That's a great answer for the money. Some companies dont reply unless new sales are involved.

Lol, you can still put it on the Sigma lens dock and try to let it keep up with the times and modern standards.

You could try sending an email to Altair Computers asking for info on their computer?
