Here are my first impressions and observations from working with the lens:
For a 400mm zoom this lens is astonishingly small
, but it feels quite heavy.
I’m currently trying to get the tripod collar off the lens. That bugger does rotate smoothly, but won't come off. This is a major setback, as the collar is in conflict with your hand when you handle the zoom-ring (which is what you mostly do with a zoom
), even when you turn it to a 1 o’clock position.
You can hold the lens by its focus ring, but honestly that is not the ring I’m going to turn often. The arrangement of zoom-ring in front, focus-ring near the body with the Nikon lenses seems now much more natural when compared to other solutions - unless you're an avid MFer. I'm curious how the Tamron 200-500mm will handle.
The problem is exacerbated by the next snag: the focus-ring turnes with AF, so you better keep your hands off
Plus the focus is not zoom-stable, meaning that you have to refocus, when you change the zoom.
AF takes it’s time, under dim conditions it starts haunting near and far, but probably more so, if your object is closer.
The switch-over between AF and MF has to be done at the cam-body is not state of the art: You have to change your holding and fiddle at the body with one hand. This is neither fast nor intuitive and you might lose tracking of your target (esp. at 400mm).
There is some play on the front-tube: you can pull the front out without influencing the position of the zoom- or focus-ring yb about 1-2mm. Whether this has an influence on focus or focal-lenght remains to me seen. At least it doesn't make a high-quality impression
You can see pictures taken for the test here
. It will be slowly filling up over time. I'll also be placing "mishaps" to give you a feeling of the "hit-rate" of the lens/body-combo in automatic...
