Mmmk here's my issue. Half the lenses I use are manual (re: manual aperture) and half are automatic natives. When I use the manuals, the camera body has no control over the aperture diaphragm so obviously the EVF preview always shows the aperture value I have set. I like this - what I see through the EVF is exactly what I'm going to get for the exposure, re: depth of field. When I use the automatics, the camera pushes the aperture wide-open for the EVF preview during composition, and then stops it down for the exposure. I do not like this - what I see is definitely not what I get for the exposure, re: depth of field. I'm assuming that the camera does this to have a cleaner, brighter EVF preview. I don't like this - if there's noise in the EVF there's going to be noise in the image. If the EVF is all jumpy then the image is going to show movement. These are things I want to know. However, I can't find anything in the menus that will make the EVF always show a 'real' preview. - 'Constant Preview' doesn't do it (I'm not actually sure what it does do...) - the camera will still open the lens up regardless of what aperture I'm using. - The 'Depth of Field Preview' button will do it but only if you press it, and it cancels if you half press the shutter. I don't want to have to press a button every time - I just want this to be default. Suggestions?
