Well , that's what the polariser is for of course George. !!

I find the best is to go outside on a blue sky day and stop down to f22. Take a picture of the sky.

The key is to stop right down.

I have not tried that screen, but my advice is that if you want to do manual focussing (I do....a lot), then a split-prism will be a much better bet.

Any framing errors can be easily corrected in pp, but out-of-focus cannot.

I use a cheaper Chinese ebay split-prism screen and it works very well. I dont find it suffers unduly from blackout with slower lenses.

Focus point is not affected , but spot metering is, so I tend not to use spot-metering and rely on the histogram/preview more.

Another vote for the second one here. i would go further and suggest you crop out the trees on the right, so the diagonal really dominates the picture.

Hi Martin

I love using the old M and "K" lenses too.

Are you using a split prism focus screen ?

I did D+P in my parents' kitchen when I was a teenager. It was fun.

What was tedious was taking all the blankets down from the windows when I had finished !

Davex is correct. It the lens has an "A" , then use it, and use the camera wheel to select aperture. This ensures that you get the available automation in P;Av;Tv etc modes.

If the lens is an old one (like M or "K") without the electrical contacts to communicate with the camera, then use Manual exposure mode.

The AF dial ? Did you mean button/switch. My K10 has on the front of the body a switch for focus method: M = manual;AF-S = auto focus single; AF-C = auto focus continous. These settings affect only focus, nothing to do with exposure.

I have to say I love the second one, crop and all (sorry Martin )

The two greens and two reds combine with the scrolls on the chairs to keep my eye moving about the picture.

Hi

I wear glasses and tried the eyepiece on my DS. I did not find the magnification outweighed the losing of the corners of the frame.

I left it on my DS when I got the K10.

I think for macro work it would be an advantage though.

Ultimately there is only one way you are going to find out the answer to your question
