Maybe you got a bad copy. My Canon-mount version of that lens doesn't seem to
have all those bad properties.

That said, I hardly ever use the lens. I bought it for a camera whose high-ISO
performance was vastly inferior to that of the cameras I own today. So an
f/1.4 lens seemed to make a lot more sense then than it does now. But compared
to the prices of today's lenses, I didn't pay a lot for it, so I don't lose
any sleep.

I used to really like my Nikkor 50mm f1.4. It worked well on my D200. I
g0t a lot of use from it in my film days, so it doesn't owe me anything.
Now, it just sits in my closet.

Oh, yeah, when I used a film Nikon, the 50mm f/1.4 was my walking-around lens
too. My wife had the even sharper 50mm f/2.0 on her Nikkormat.

Now I think we have only two prime lenses in our collection: the
aforementioned 30mm f/1.4 and Martha's beloved 60mm f/2.8 macro. Everything
else is a zoom. It's quite a different world.

During the transition from film to digital I've kept my 50mm f1.4 Nikkor
lens. It's as good a lens now as it was back I was with film. Used with
one of my DX cameras, it becomes a decent 75mm group portrait lens. In
the bright light of the day, when used with various Neutral Density
filters (to allow use of more open f-stops) it's a good lens t use for
beach/desert scenes.

My primary prime is my 200mm micro Nikkor. Once in a while I use the
20mm f4 and my 24mm f2.8. I recently used the 20 for street. I also use
my 10.5 semi fisheye. I am giving serious thought to a long telephoto.
So I guess one can say I am still in my prime.
However, I agree that times are changing. I find myself putting
extension tubes on my 70-299, for closeup work.

I have been getting a lot of CA with digital that I never got with film.

Has that been just with the 50mm f1.4 lens? It seems like we have been
dealing with chromatic aberration for quite some time when going digital.

And those who place the blame as Rich describes also maintain that lenses
introduced since the digital revolution are specifically designed to minimize
the digital form of CA. And that they therefore outperform (on digital
cameras) older film-camera lenses of comparable optical quality.
