Too bad

Who was talking about front lens converters?
I was at least talking about a rear lens converter, because the ASP-C sensor doesn't use the whole image a FA lens throws a 0.66x converter might work because such a converter use the AOV the lens was intended for.

I use a ball-head on my mono and I don't just use it for long lenses, I've used it at 18mm as well for long exposure shots up to a second.

Many even advice to use a ball head so you can put the monopod into the optimal position to stabilize everything.
The idea is to swing the leg out to the front a bit and use that leg and your own two legs so that you get a tripod.
There are also other position you can use. link

If you don't use the portrait mode or have a collar on the lens then a head like K10D suggest will be good enough.

Paul you need good light though.
Some even talk about 20-30 seconds at f8 or f5.6 ISO 1600 so take your tripod with you.

Some companies are able to remove the filter infront of the sensor and replace it with one that doesn't cut infra red light or replace it even with an infra red filter so you don't need to use one infront of the lens.

My is the last two letters from my first name, the first letter of the first part of my last name and the first letter of the second part of my last name.
Mike will probably say now that i complicate things again

Glyn I thought the contacts did line up, they are both on the same side right?
The outer two contacts of the k7 carry the charge the middle one is not needed by my knowledge, that one is used to check the temperature of the battery.

The K-M and the K10D sensors are the same.
It has a filter that cuts Infra-red light so you need to use very long exposures.
I used 1 second at ISO400 for that shot, as you can see the sun was even in the photo so with other shots you might need to push it even to 2 to 4 seconds.

Going to a concert and i need some tips and stories so that i know what to expect.

I'm thinking of using the DA*16-50 and DA*50-135, that should cover everything with f/2.8
My only camera is the K10D unless the K5 gets released before a Thursday
I might be able to lend my uncles KX if high ISO is needed, do you think that's wise?

Got 3 entries now and two pending because of sizing, if things are resolved i'll show you the teasers.
