Wow! Stunning images, Art!
You're tempting me to sell my "heavy" 500 f/4...
Thank you, Herman.
Wait until I give it a good testing over. The day these were taken was a bit overcast and I was a bit challenged for light and the lens is new in my hands. Have VR on sometimes, off others. Look for the right setting and the right circumstances for a really good testing. When I do that, I will give you my honest opinion. And, I always shot maximum aperture. No real test to find the sweet spot.
When I took it to the track, this past summer [Nikon NPS], it performed wonderfully and the images were solid. I would say as good as anything I would have gotten from my 200-400mm under similar circumstances.
I think the 500 prime is a force to be reckoned with and I am not so sure I would give it up, just like that. I don't think I got my hands on a 500mm prime yet, maybe I will borrow one just to do a side by side comparison.
I think, I can get sharper images than what I just posted with the PF, give me a few weeks to find an opening in the weather. This is our worst time of year and we are having a weird winter here so far. First real good sunny day, I will take it out again, then we can talk.
I also think that you get more richness in a prime, but I could be wrong. I don't know, which is one of the reasons why I have been waffling on this so long. I am still tempted to return this and get that 300mm f2.8. A heavy pig, but WOW, the optics are incredible. I am still thinking about it.
