48 hours later.......... maybe the lens is just a tad better but not enough to say for sure. I'm still at about a half stop slower than my 35mm f/2.8 ais at f/4 with just a hint of yellow still visible, maybe that is just normal for the lens. There was a marked improvement during the first UV session and perhaps and I am just ocd'ing it now. I did check light transmission at f/4 on my 50mm f/1.4 Nikkor-S against my 50mm f/1.8 ais as a cross check. Interestingly the older Nikkor-S was a half stop brighter at f/4..... Things that make you go "Hmmmm". I was using My F4s on spot metering to do the checks. I shot a roll of Ektar using the lens. It produces great pictures. Here is a link to the shots for those that are interested. All shots were with the 35mm f/1.4 Nikkor-N Auto AI on a Nikon F Photomic FTn.
