Originally posted by Wheatfield That's ki d of the reverse of my point. To do it today with anything better than cheap kit zoom quality, it's going to be expensive. For Pentax to do it based on how many they can expect to sell, it will rival buying a seat on Jeff Bezos' rocket ship.
If it would cost the same as a trip on one of Bezo's rockets, we just need to convince William Shatner to fund it
I tend to agree. Unless they do something wacky, like Canon's new inexpensive telephotos, but SLR viewfinders don't like those slow apertures, so Pentax can't play the same trick...
And I don't think Ricoh has the expertise to do something like the old 400-600 mirror lens in a modern form... and it would have the same problem as above...
Unless something completely unexpected materializes, I think we're stuck with the 150-450 as the longest lens for the foreseeable future...
