<p>Could be an idea Ilkka to try a new focusing screen, I did try the DF in Rajalacamera with the kit 50mm but I could not alway achieve accurate manual focus with it. It seem to be a little off it looked sharp in the viewfinder but I aways got a sharper shot using the AF. I went with the Sony A7 as a manual focus camera for my AIS nikons and my LTM lenses. I'm not sure about the EVF still, it is better than my X100 EVF and the XE-1 that I don't have any more. I do wonder if a DF with a different screen could be right for me but the DF is a little pricy for what it is and some how it felt more uncomfortable to hold than the A7 even though the DF is larger. A D800 type body with a better viewfinder would be great for me also.</p>
