I had an inquiry today with regard to the new AF-S version vs. the old AF one:
I'm looking for a 50mm lens for my Nikon D80.
I'm torn between the new and the old version of the Nikkor 50mm/1,4.
That why I enjoyed your review and review diary.
But basically, what would you recommend taking in mind that the 1,4D is approximatly 120EUR cheaper than the new 1,4G.
I can autofocus with the 1,4D while D80 has a build-in motor, right?
both are usable on FX models right? (eventually we will all upgrade to full frame)
Yes, you're right: both lenses are FX-capable and both work on your D80/90 etc.
What made me switch from the AF to the AF-S version was some unrliability I encountered with the older version in auto-focussing. My lens could sometimes be really off on my D80. Not so much that I immediately recogized it when looking through the viewfinder but when reviewing the image on my computer I had to consider the shot a loss.
that this resulted from some type of aberration that this lens had and which fooled the AF-system of the D80 into thinking that the image was perfectly in focus. It did only happen a few times but I became reluctant to trust the lens.
With the new AF-S on my D300 I had some cases where the focus settled totally off, but in this case you could easily see it in the viewfinder and you could give it a second try. When the AF-system found focus the focus-quality is very good.
So all in all it is not easy to give a recoomendation here, because the cases of bad focussed images on the old lens were not often. So you have to decide how much the additional peace of mind together with faster focussing and some better IQ is worth the higher price.
