Thank you all for the info on fish-eye lenses! The photo.net article
is just what I needed!
I think I have seen the Pelang lens on eBay but there does not seem
to be one there now, and pitifully little information on the web at
large.
So I will get a Zenitar and see if that fulfill my needs.
There are already some new lenses made for the APS size sensor and
unless all DLSRs progress to a full size sensor we will most likely
see more really short lenses in the future.
The Pentax roadmap lists a fish-eye zoom of about 10-20mm but there
is already the 12-24mm zoom to buy. Hopefully, we will see a Pentax
version of the Sigma 10-20mm zoom too.
