[quote:3496ace15f="The_archaeologist"]Nobody has mentioned Pentax anoraks...and curiously enough I think I've just stumbled upon a collection of them!

I had this very issue with mine, they have a Ricoh pin which allows them to be mounted on Ricoh cameras but this pin catches on the autofocus connection on DSLRs.
It is very simple to remove, I will send you a PM with the link to how to remove it.
Thanks for sharing the link with everyone Andrew.

7 Bodies
17 lenses, (11 primes/6 zooms)
2 Flashes
4+ filters
1 Bag
1 motorwinder (I think my other is a 3rd Party clone)
1 eyepiece magnifier
1 helicoid extention tube
I'm not including seperate books/manuals it would take too long to confirm if they are, published by Pentax or only about them, genuine/copies.
I don't know how many of my T2/M42 adapters etc are Pentax brand ones, so they'll all get excluded as well.

The advantages of Digital are, instant feedback, cheaper cost per shot, easier editing, variable ISO, easier storage/transmission...
Even with the very beat digital sensors there is some debate as to if it offers superior IQ or resolution to equivalnet size film. I've seen technical 'proof' of both sides of the argument some claiming digital had supassed film 5-10 years ago, and others that it's still got a long way to go.

Even after years of practice most of my panning shots are not even worth showing to the kids.

Yes, I'm sure you're right and if anyone were ever foolish enough to pay me to produce a bill-board size photographs then, no doubt, I'd have to buy a 6x7 film camera. But until then... well, you get the idea. Just a simple amateur taking a few snaps!
Given the typical viewing distances for billboards, I wouldn't be suprised is many of the more action type ads don't use DSLRs today.

I may need an assistant to carry it around for me
Not to mention a lottery winner to buy it for me any offers:
If you supply the stake money I'd even buy the lens for you as long as the winnings cover it, and my expenses.
I'd even carry it for you (attached to my camera & probably being used when ever you want it) except of course you're the wrong side of the UK.

As others have mentioned there are TCs with built in variable extension designed for macro.
Neither of mine work well for distant subjects being very soft when supposedly focused at infinty.
Yes TCs magnify any imperfections in your lens as well as potential introducing loads of their own. But remember even extension magnifies the aberations of your lens - if it didn't you wouldn't get a bigger image! The big advantage for TCs is they don't effect the minimum focusing distance of the lens used on them few 100mm lenses will focus as close as a std 50mm lens. The extra magnification also means you don't need to get quite so close for skitish subjects.
If you use them with extension tubes as well you get an increased flexibility in your system without increasing your bag weight as magnication will be different depending if the TC is before or after the tube(s). The combinded affect on lens aberations may well make it a pointless excercise though.

FF d-slr
budget non WR d-slr
& one other d-slr replacement?
with 2 of them coming in AA filterless (or IR) variants.
or even:
FF d-slr with AA variant & IR variant
IR variant K5II
IR variant K30 or K-01
Development/production costs of IR versions are minimal, and Pentax have already done it with the 645D!
