I sold a few on Ebay so I am doing it all over again
Hopefully I will finally settle on a selection and stick with them.

I would have bought the K20D a long time ago if the Liveview had been better with a tiltable screen.
What I am after is something like the Canon 40D where you can zoom in 100% and use it as a focus aid for macro.

Too late, its sold

Mine was delivered yesterday after 5 months of negotiations.
We agreed on a price before Xmas but as I did not know the seller at all and he didnt know me we had a bit of a problem doing the deal.
Anyway, he had to go to a wedding this week in cornwall and stopped halfway to collect his cash and drop off the lens.
It has a small dust speck which makes no difference but apart from that is mint, I committed myself to it before buying the Pentax A* 300mm f2.8 and teleconverters and couldn't let the seller down after such a long time but at £400 I could probably sell it on fairly easily.

What I was fairly impressed with though was when I tried it with the Sigma EX .4x teleconverter that I use with the 70-200mm f2.8.

And there was me thinking its time to upgrade to a K20D in the next few weeks.
Maybe it's not ..

The 1.4X-L and 2XL converters are superb but unfortunately only work with a few Pentax lenses.

Pentax cameras do not show the extra stops that the 2x teleconverter adds when attached so you lost 2 stops when using it.

Its very easy to do with the provided tweezers that come with the screen (I did exactly the same thing).
Best to do it in the bathroom or similar as there is very little dust in places like that.
I did mine in the shower cubicle.

Im pretty sure it is TTL but not P-TTL so therefor ok for older Pentax digital but not for anything from around the K100D onewards.
Can probably use it in manual mode if it has one though.

Are they?
I didnt think the Jessops flash had P-TTL.
