Great Dpbours 2009-02-16 3:54

Hello Jean Pierre,

The dynamic light control of the D300 surely has big advantages with this one. The ceiling comes out quite well, though in a pretty dark space there. Nice.
The 50mm f/1.4G. I have the old one and I'm not sure what the big advantage is at 50mm of the silent wave motor. I normally don't need to focus speed at a fixed focal length lense, but yes it is a nice improment technically.

Greetings!
Dennis

Default To Dpbours: 50mm AFS

Dont worry ! The new 50mm ultrasonic motor is slow ( perhaps the old AFD is faster...) but the focus precison is stunning. I think it's the best way when you need a very low DOF. I dont think this lens is made to be used at f/16 !!!!!
Thnaks for passing by

That is interesting to hear that it is perhaps slower than the old AFD! The focus precision in the old 50mm is already spot-on!

Think the lenses are more or less identical and the new one is mostly for users of the D40x etc without a AF servo in the body.

Greetings! Dennis

Not slower but same speed as AFD on a D300. Slower than the pro zoom 17-55 or 70-200.
I have sold my AiS 50 f/1.2 without autofocus : very difficult to get the right focus with my old eyes !
Construction is better than AFD due to IF design and moisture protection, also rounded 9 blades diaph and sharper than AFD at 1.4.
Don't need to change the old design to the new one.

Yes, true about the moisture protection. No one thinking about rain back then. Surely the developers have never been to the Netherlands or the UK ;-)
