I was out shooting with my D2H and 300 2.8. I was trying to get some shots of the Eagles that are nesting in our area. The Eagles never showed up, but I spent a couple of hours taking test shots. What I found was that my 300 2.8 is front-focusing pretty badly. I should note that my 300 2.8 was attached to my D2H when I fell back in August, requiring $485 in repairs to the D2H. I thought that the 300 2.8 was OK, but now I'm not so sure. Since I was waiting for the Eagles, I had the 1.4 TC mounted. When I carefully aimed and focused on a well-lit stationary object, the image through the viewfinder didn't look as sharp as I expected. Sure enough, after some experimentation, I was able to get much sharper view by turning the focus ring about 1 degree or so, toward infinity. This was 100% repeatable over many cycles. After doing this many times, I put the 1.7 TC on. It did the same thing, though to a lesser degree (very small adjustment needed to get perfect focus). So, my question is does anyone have any words of wisdom, or have any of you had a similar experience? Right now, I'm leaning toward sending the 300 in for inspection by Nikon, but I think that I might croak from withdrawal.
