Went into the magic latern book since i don't have an old lens by the hand and it said nothing with KA lenses but with K or M42 it says: "The built-in flash will always fire at full power and will rarely provide correct flash exposure, and the FGZ series flash units wil not provide the high-tech P-TTL controll." this from the K10D book but the camera's are almost the same.

It might be a problem in what camera mode you're shooting but if you set everything on munual it will certainly need to work no matter what lens you're using, if it doesn't it must be a fault somewhere so simply go back to the shop we can't do much without holding your camera in our hands.

edit: typos

The K20D is a complex camera you really should need to learn what everything is if you want to get the most out of it.

Like Pete said go out with the camera and use the book for reference but first read the manual and try all the option and customize the camera to your liking, that's what I would do.

Hey Amin,

How much do you see through the viewfinder, can you still read the numbers clearly on the bottom?
I now need to move a little bit to read them since my eye is already further from the screen and I'm worried to I only see half of what you see if I would use the eye piece

It's good to be back indeed, will upload some in the hour.
Just need to tweak them a little bit ^^

No, no problem at all besides what has been said and P-TTL doesn't work with that lens.
I know I'm very helpfull now...

Amin,

I've internet now *woohoo*
Will upload some shots shortly first need to answer all me mails now though

How is the eye-piece working, I was thinking of getting one too but didn't do it in the end since I wear glasses and wasn't sure how much I see through it.

I use MF all the time, I already dropped a comment how I use it.
With portrait I use it a lot too since you want to have the eyes in focus and the AF doesn't understand that always

Amin,
most/some users here have removed the autofocus from the release button and only use the AF button for autofocus. I also have it like that and leave the camera in autfocus but since it doesn't focus anymore while pressing the button it's like manual focus and if I do need autofocus I simply press the AF button.

Hi Amin,

Yes I also had exams but just kept shooting ou need to relax sometime right.
I also have some photos of the course that I'm doing, I might upload some if I've the time

The camera can handel some moist. I've used the camera in a swimming pool, it was like a tropic rain forest in there and it got fogged in less then a second because the camera was cold since it was freezing out side. I used the 18-250 and only the front element got fogged so there wasn't coming moist on the inside while using it or else the inner elements get fogged too right?
The weather here is almost like your weather and I've taking it out it out in the rain many times with all the lenses what I've without any ill effect so far.

3.5 and 4 so out of the head

Well almost right but you got the idea, it depends in what mode the flash is (trailing curting, highspeed, etc.) that depends on how the camera reacts as well.
you can use the flash closer if you flip out the plastic defuser screen btw

If you use the AF360 in low light it use the spot-beam (it's called that i think) it shines a red grid on the subject that helps the camera to focus so it should be able to focus correctly.

Lowepro have some rugsack for your need if it isn't more then a day hike.
This is quite a nice one i believe Primus-AW
