Is it true that you can crawl inside to clean the inner elements?

To photograph wildlife, you leave the lens outside, and eventually a bird builds a nest inside the lens hood - a great blue heron.

Forget the Sigma, this Pentax 6x7 800/4 is bigger (17.7kg) and with an adaptor you can use it on a Pentax 35mm body as an 800/4 lens.

In case anyone is still following this thread, I did some research into largest & most expensive lens ever made for "civilian" use (discounting astronomic and military surveillance). It was a Leica, APO Telyt 1600mm f5.6. Only two were made, a prototype and one ordered directly by a sheik from Quatar. Cost: about $2,000,000 (yes, that is two million US dollars); weight: 60kg (132lb). A Pentax K3 with 17-70mm could sit inside the lens hood, camera resting on its back (lens hood diameter: 42cm = about 17 inches). Wonder if it will turn up on EBAY? Maybe Leitax will supply a mount converter.

However, Zeiss apparently offers, and will make on order, a 1700mm f4.0 (yes, that is the correct aperture) which weighs a reported 565lb (~256kg). Last price quote was something unspecified over $100,000. Presumably they would make it in Pentax mount.

And Canon made, maybe would make again, a specialty multi-mirror 5600mm f14. Could not find a price.

If you need that focal length with zoom capability and the weight is too much there is always this option
