Hello, this is my only manual focus lens and I really struggle nailing the focus with it. I did mainly buy it to play around with the f/1.2 aperture so that doesn't help! I find when shooting with it the focus looks dead on in the viewfinder or the LCD but when reviewing the image later on the computer or in camera the focus is off just enough to ruin the photo. I've tried most of the things I can think of: using a higher shutter speed, usually the case when shooting at f/1.2, as well as the various focus assist features built into the camera, focus peaking, groundglass, split image and zooming in while focusing. None seem to help me much.
I have many years of manual focus experience using film cameras with no problem. But don't seem to have much luck with this lens on my Fuji's (xe-2s and xS10). Any help with this lens or advice on manual focusing in the digital age would be appreciated. Thanks, Jim White
