just for fun, as you can't really get it, but here it is, the longest one for Hasselblad:

and yes, it in fact exists. I have seen one at the Photokina.

should work with leaf shutter and AF

and combined with one of the available tele converters, either for HC or for XCD lenses, you will get 510 mm.

Maxcast is indeed a member and posted once in November 23. I am keeping an eye on their account.

A search shows no posts. I can't check members though.

This, but it weighs 14 pounds. 800mm f/6.7

Less insane is this. Only 10 pounds. 600mm f/5.6

There's a mirror 1000mm f/8, if you don't care about the bokeh.

Curious what is the longest telephoto lens I can get? Don't really care if I need to use electronic shutter, as I'm only shooting static landscapes. Manual focus is fine. Corner to corner sharpness is highly desired though. Aperture pass though is a nice to have, but not a deal breaker. Basically I'm looking for something which can match Fuji's upcoming 500 5.6 lens for their GFX line up

Thanks!

There is another option.  Instead of waiting for the alert - I ordered the 38V from B&H on Jan 18 - backordered.  They don't charge your credit card until the item is shipped.  Mine was shipped on Feb 28, and I didn't have to fight others who were waiting for the alert.  I know they were sold out almost immediately.  If you get your lens from another source, you can always cancel your order (with B&H).
