<p>I started photography in the digital era (a few years back) so I have never used a film camera or manual focus lenses. I heard digital bodies like my d800e and d4 are not designed to be used for manual focus because of the limited viewfinder etc. Given zeiss has recently released the sharpest lens ever made (according to Dxomark) for nikon bodies, 55mm f/1.4 and 135mm f/2, and also because of the availability of highly rated yet affordable samyang MF fisheye, 24mm , 35mm, 85mm lenses, I am real tempted to give it a try. I will probably still stick to my nikkors' autofocus for wedding work, but I wondering how feasible is it to use these manual focus lenses for slower paced shooting? <br> I know there is focus confirmation green dot thing,but how accurate are they in my cameras? I can certainly try to "autofocus fine tune" them to assist me better in the field, but are they any good given they are tuned properly?<br> Also I read there's this belief about the viewfinder not being able to distinguish any difference in depth of field under f/2.8? assuming that will make the manual focus even more difficult because it would appear to be in focus in the viewfinder when in reality at f/1.4 it's not.<br> What are your thoughts? does focusing screens work as advertised? (i am a bit hesitant about putting 3rd party parts into my cameras even if they are available, afraid they might screw up anything or making the viewfinder hard to read)<br> What are your thoughts? are any of you manual focusing with excellent results? should i invest my time to learning MF or it's better to stay away coz i will go blind doing that? Thanks for any comments</p> <p>It's a shame the Df didnt have the viewfinder from a film camera....</p>
