We will now find out if Ghostless SMC is actually significantly better than other coatings or if its all just marketing really. Well we'll see the difference vs Tokina coatings anyway.

very cool abstract

My cousin got stuck in her 4x4. I was surprised, until I discovered that she didn't know how to engage the four-wheel-drive. Amazing.

I learned to drive in a Land Rover on mud, and I'd be willing to bet I can take my Peugeot 306 (2wd, diesel) to places most people in 4x4s couldn't get.
Putting average mother(or father)-of-two in a 4x4 and expecting them not to get stuck is like giving them a K10D and expecting them to turn into Ansel Adams, except worse because most 4x4s don't have a Green Button.

Yep, we had some snow, and as Gwyn said, everything ground to a halt. Schools shut because presumably it's too much of a problem to get there (in the 4x4 ).
"get out of my way, I have 4 wheel drive so I can do 60mph in 3 inches of snow!.......hey, how did I end up in this ditch?"

Unfortunately there aren't very many Mongooses around in Cambridgeshire, so unless I can figure a way to take a panned self portrait I'll have to try the SR panning on something else lol.

There are image stabilisation systems 'out there' that have the option of single dimension stabiliation - but that option is not present on the Pentax clearly. I wonder if they could add it as a firmaware update?
BTW the pentax SR is described as three dimensional - which I guess means horizontal, vertical and rotational. The latter is clever (and not available in lens based system C***n and N***n please note) but is not realy a third dimension.
There's only one way to find out, someone's going to have to go take some panned shots with and without SR and see what happens. I know, I know, its a chore, I know how much we all hate using our K10D's, but I think it has to be done.

Panning involves a lot of movement in one direction, so there are two possibilities as to what will happen that I can see
1. The SR gets confused, throws it's rattle out of the pram and causes all sorts of issues because it can't move the sensor far enough.
2. The SR throws the sensor to full horrizontal deflection very quickly, but vertical deflection is still available so it continues to work and provides a useful bonus
not sure which I think will happen, but it's worthy of a try.

As I said the 80-320 is very happy on a K1000 so should work wonders on a KM. It's focus ring is rather loose by comparison to MF lenses, but it's useable.

I have no knowledge of the 100-300mm.
the 80-320 and 50-200 are both very good lenses for the money.
The 50-200 has manual focus override, a smoother zoom ring and a non-rotating front element. It is also smaller and lighter.
The 80-320 obviously has a little more reach at the long end, at 200mm it's faster (both are 4.5-5.6 lenses but the 80-320 is still 4.5 at 200mm) and its 8 aperture blades make for nice smooth out of focus regions. May or may not bother you but the 80-320 is also compatible with every K mount body (I've used mine on a K1000 once or twice) where the 50-200 is digital only.

last I heared the joint designs extended only to the optical layout, each company then makes the lenses itself, including glass coatings. These lenses are not like the Pentax/Schneider ones for Samsung, they are totally independant except for the optical layout.
Pentax have SSM technology, but it appears they arn't giving that technology to Tokina. Perhaps the SSM is the reason the Pentax versions aren't out yet? taking some fine tuning perhaps?
