I'm not sure if anyone here has had experience with all four of the above mentioned lenses, but I'm wondering how they compare when it comes to flare and ghosting. I currently shoot with the 50/1.4G. I actually think it's something of an underrated lens...my copy at least is quite sharp. I shoot documentary work but with a heavy focus on the landscape--so I occasionally shoot handheld but I also work on a tripod with my D800E bodies. I'm just mentioning this because resolution and corner sharpness are important to me, but the overall look is really more important. I've noticed that the 50/1.4G does have quite a bit of flare and ghosting. I've been shooting a project on natural gas drilling and when shooting the rigs at night, the lights flare out quite a bit. Sometimes they flare the gas wells which produces a large flame shooting into the sky, and shooting those at night is impossible with the 50/1.4G. I don't mind some flare in some situations, but with this lens it's just ugly. Has anyone tested these lenses for night shooting with bright lights within the frame? I've found that the 50/1.4G produces ghost spots when small light sources are in the frame and if a large, very bright light source is in the frame it basically washes out completely and produces large, aperture-shaped flare spots. These effects don't change much with aperture. And yes, I've tried shooting both with and without a B+W brand MRC multicoated UV filter. I'd prefer to stick with Nikkors but my Zeiss 35/2 doesn't flare much at all. Unfortunately I really want a 50mm.
