It is most probably due to improper white balance which could be corrected in PP.
for what it's worth, my copy is extremely yellowed, and i'm undecided about whether i should bother fixing it. you can see from my photos that auto white balance compensates for the yellowing so my images don't look yellow (unless i want them too), but it does act as a yellow filter changing what light gets to the sensor. thus, the color balance is different than when i shoot from an unyellowed lens even if i set white balance on the same shot in the photo.

Hi sebboh,
You may also find that the lens needs up to a stop more light, due to the yellowing. Yes, you get the shallow DOF, in this case altered light balance, and a slower lens requiring more light for exposure.

actually just 1/2 a stop, i measured when i first got the lens. i was going to expose it to UV just for that reason, but since i use it mainly on a camera with image stabilization i really haven't been bothered by not having enough light with it yet. it's bound to come sooner or later, i should probably just fix it and get a yellow filter for those occasions when i miss the look.
Thanks Wayne. Hopefully that sad face of his will pay off and he will get adopted! I have been photographing all the dogs at my local shelter in hopes of getting them better "exposure" (pun intended) and have had a great reception so far. All the dogs (but for one) that I shot a week ago were adopted within a few days. This day was so cold and gloomy that I had no good lighting whatsoever to work with. That, combined with only having old Rokkor manual focus lenses to use on the NEX makes shooting these animals quite a workout! Thank goodness for the focus assist thingy (I forget what it's called now) on the NEX!
Very inspiring, I finally ebayed a 1964 thorium version 58/1.2 (EOS converted) to use on a 5D2 and NEX5N. Hope it arrives and fulfills some of the promises found here :-)
Its another stitch, this time just 3 shots though. Yes, wide open.
Great news on the lens! I love mine, let me know if yours has any wobbles at all. Mine could do with tightening up but I'm a little worried about tampering with it. Both the mount and the focus ring have a tiny amount of play.
looks like you'll have fun with that lens.
