I am new to the digital SLR. I favor a purist mechanical camera like the Nikon F, so there is a desire to tame modern tools and render them as simple platforms as possible, then be able to change an internal capability if needed. This is probably why it has taken me so long to get into the digital world beyond P&S. As far as customizing the Df, I have been able to turn-off the red focus bracket and focus point illuminator, as I would only need it when focusing on a black jacket in a closet. While most would consider this a minor thing, I don't like distractions. I like to take the time think about the metering variables and review viewfinder information, so I set the meter to remain on for 30 seconds. In time, I will learn how to meter naturally beyond Sunny 16. With ISO as a new variable, is there a revised Sunny 16 rule for the digital world? My preference is to setup the Df in manual mode with a Non-AI lens, in this case, a 1972 or so Nikkor-H 85/1.8. This day of age, I would expect a retro digital camera to read the Non-AI lens aperture as I change it manually, but I will deal with notifying the Df the change I made on the lens. Actually, I don't bother to change the lens aperture until I have metered the calculated aperture in the Df and reach a happy value, then I change the lens aperture before shooting. I set the Df to limit the shutter speed close to the focal length of the lens to minimize camera shake. By setting ISO to auto, I get an immediate recommended meter reading after selecting the aperture in the sub command dial. BTW, this dial is awfully stiff for my taste, as the position and configuration of this dial does not need protection. I want the focus point (a single box) to remain on the VF screen to compare my eye to the focus confirmation light, but I would like to turn-off the wide focus bracket on the screen, as I do not use it. I still don't need the focus bracket if I ever need to move the focus point around. Has anyone been able to turn-off the wide Df focus bracket (without removing the battery, of course)?
