Do you think we can get Sigma to do a K mount version?

Saw a post on Facebook where someone mentioned the Sigma 200-500 f2.8. I had never heard of it. So as usual I googled it and found this. I would think that combined with the K1 II’s low light performance we should be able to capture the Big Bang.

Why would I need another one? Binoculars?

My back could never handle that!

But you could probably shoot the geysers in Yellowstone without leaving your house.

If - in all seriousness - you can afford that lens, you buy a body that fits it. It is so highly specialized you might just dedicate a body to it. This pic really brings the size into perspective.

I hear @LeRolls is considering it for his main portrait lens.

That stiletto heel is going to scratch the lens body if she's not careful. Obviously doesn't look after her photography gear...

Read the hilarious 'customer' comments at Amazon:

amazon.com : Sigma 200-500mm f/2.8 APO EX DG Ultra-Telephoto Zoom Lens for Canon DSLR Cameras : Camera Lenses : Camera & Photo?tag=pentaxforums-20&

And the Q&A's are equally gut-splitting.

They used to list Pentax as a mount option. At $26,000 USD I don't know if they ever sold one.

That lens is so large it needs its own battery to run the zoom and AF motor.

I’d say that body goes very well with the lens.

The body that goes with that lens adds considerably to the price, but if you can afford the lens then maybe the body is no problem.

Sigma made K mount lenses until fairly recently(*) but terminated production because of low demand.

This bad boy, however, is/was only available in Canon, Nikon, and Sigma mount.

If you really, really want to use it with a K1, get a Nikon mount and do a Leitax conversion on it. Alternatively, just get a D850 or a Z7. Or a nice new car.

(*) not sure exactly when but I think it was about a year ago

PS: for capturing the Big Bang something like this would work a lot better.

The short answer to "can we convince sigma" is always no, no matter what lens you are talking about.
