300mm AF-S with 1.4x TC, ISO200, 1/250s @F8
So why mention the focus errors at all, they are part of the reason that I have not come home with as many photos on my memory card. I have missed a number of good shots as a results of these focus problems. In some cases I did get a photo, but they are softer than I would like so it is unlikely that they will ever be seen by anyone other than myself. I still have enjoyed the outings, but not getting some of the photos I would like to have does put a damper on the day. Yesterday I got some photos of an American Bittern, I haven't seen one in about a year, and I was disappointed to find that due to the fact that the Bittern was in mixed light the focus was slightly off. I got some better photos last year so I'm not overly concerned though.
This just highlights why I would love to have a lens like the Nikon 200-400mm F4 VR, which incidentally was updated by Nikon this week (Now it is the Nikon 200-400mm F4 VRII). With the lens being updated it gets even farther from my reach though, going from a $6100 Cdn lens to a $7000 Cdn lens. If I were to make money from my photography, I would go for that lens as soon as possible, because it would give me a lot more flexibility, not to mention that it is F4, even at 400mm, which would be great. In reality, I may never get the telephoto zoom I want due to price, but, if Nikon ever updates or replaces the 80-400mm F4.5-5.6D VR with an AF-S model, then I might be happy with that.
Just a quick update as well, I am working on the third part of the lens purchasing guide and so that should be up some time in the next week or so.
