Why the manual one Rob, Is it much better optically?
I notice that Nikon still sell an extensive range of manual prime lenses, Calumet list about 8 at different focal lengths.

I don't know it it's better or not - the difference, though, is in my head: I don't like the idea of losing control to a machine. I'm of the old school, and dislike change where I can't see any huge advantage to it. All of my Nikkors are manual except for the 2.8/180 but I have that set to manual, anyway.
I'm fairly sure that, if I had to do sports work, then I'd have totally different ideas, but I don't do anything like that so it's academic. However, I do get an emotional buzz from the physical experience of seeing a subject come in and out of focus as I turn the ring, especially when using longer optics - I imagine you lose all of that response when a machine does an almost instant adjustment for you. For me focussing is all a part of the great experience of shooting a picture, not something to try and avoid doing; however, with failing eyes, this may all change or simply grind to a halt if I find it becomes more angst than joy.
Oh -a bit off topic, but regarding the depth of field lines on Nikkors, I find the coloured technique they use next to useless: even when my eyes were pretty damned perfect I couldn't rapidly work out which colour was meant to represent which stop; crappy cop-out from doing it properly, but better than what you get with af nowadays.
