I use the stop down lever for all my manual lenses and have got used to how much under / over exposure each lens needs and just set it on the display in the viewfinder.

I test by setting the exposure asked for on the green button, judging the image, and then if it's too dark I add a stop at a time until it's looking ok. If that's +1 stop then when I use the lens and expose using the stop down lever I add a stop by looking at the exposure meter in the viewfinder.

If that makes sense ?

Looks like a horrible lens to me. But try some normal setting, since you are now trying to make a picture of a tree with air behind it, and that's the perfect setting to get underexposed subject.

I have a Nikon 300mm/f4.5 that is attached with an adapter making it a 375mm/f5.6 lens (or about).
If it doesn't make this then it is probably not word to make an efford.

Thanks everyone. I have not had chance today to try suggestions 1 and 3 that ducdao said above. I must say, it's a lot more hassle with a manual lens than the normal ones.

I have noticed that when you press the EAL button as said on that link, it's goes to something like 1.5 and that is to low from what ducdao said.
I end up using the wheel to bring it up to about 250.

One thing I like about the lens is, it is wider than my pentax 50-200 lens, so is better for night shots I think, as it lets more light in.

Btw got myself a used temeron 70-300 lens from auction. So that should be simpler to use.

Well have to practice a bit more with this manual lense.

Irfan can correct a lot of the problems with the pervious photos I took, with auto color adjustment.

it's certainly not a 'horrible lens' - but it isn't the easiest to use if you're not used to the two ring stop down method of working, especially if you're new to MF lenses.
I set the silver ring with the detents to f22 and then set the aperture with the black 'stop down' ring, it's not exactly how it was designed to be used but it's quicker and easier that way.
