Paul, I recall your mentioning not having done any sharpening to the 150-450 examples you posted. I think that some moderate sharpening certainly and even a tad of ERC "clarify" would be reasonable and more realistic. I believe it's intended that digital images be sharpened.

It’s dark and gloomy in Michigan and raining intermittently, so I resisted the urge to go looking for birds and instead set the fine focus adjustment, then took a couple of sample pics. My tests showed the lens was back focusing a bit, and a +4 setting brought it right in throughout the range. It’s built like a tank, there’s no wobble or looseness, and the zoom is as tight as any lens i’ve ever owned. (One reviewer mentioned zoom creep. If that ever was a problem, it’s definitely been resolved. You have to expend a fair amount of effort to change the focal length.) I shot some dead ferns off a tripod at 450mm, ISO 3200, f5.6, 1/60th. http://photo.net/photodb/photo?photo_id=18141845&size=lg Here’s a 100% crop of the area where I placed the focal point http://photo.net/photodb/photo?photo_id=18141846&size=lg Very pleased thus far. Can’t wait to try it out on some birdies.
