Nicely done, I do like #1 and #5

The SRB resin filters have had good reviews in various photo mags, recently tried a 0.6 soft grad and very pleased, they come in a nice imitation leather wallet to keep them clean and as scratch free as poss.

I would change the ISO initially to 800, see what your shutter speed is and go up as far as 1600 ISO or come down to 400 iso. You'll need to keep the shutter speed ideally around 1/200th of a second to freeze some movement, and a minimum of 1/100th to eliminate camera shake.

Keep the Lens around F5,6 / F6.3 for reasonable DOF

Depending on the available light, you should get something from settings similar to 800 iso, F4.5 and a 20 second exposure, use " Bulb " the " B " on the dial and just hold your finger on the trigger, as Jonathon suggests there is a reference shot taken after a long exposure aimed to eliminate noise, you can turn this feature off in the menu's if you wish.

Also switch to manual focus, the lens may not be obtaining focus confirmation and if the option is turned off in the menu's the shutter wont fire, focus on the light, re-compose and try again.

Its only a hours drive from Birmingham

Second Derek's suggestion

Personally I would stay with the K5iis, been reading about the differences stated by PU users and love the low light abilities and decent high ISO usage of the iis.

Airshow wise, I've done many with just a 100 - 300 F4 and crop slightly as required, there's quite often Sigma lenses off either 50/150 - 500 or the 100 - 300 that come available on this forum and I wouldn't let the discussion with Sigma put you off Pentax.

If you decide on Slimbridge again let me know and see if we can meet up.
