I picked this up the other day and the kindly letter carrier delivered it today (Saturday), even though it wasn't due for delivery until Monday. Wasn"t that nice? Brown and FredEx could learn something here, but I digress. Lens @ 80mm The lens is 8.25 inches long as its shortest setting when mounted on the NEX adapter (rear lens cap to front of filter ring) and 11.75 inches long from the rear lens cap to the front of the hood. Lens @ 400mm Lens @ 80mm w/hood Lens @ 400mm w/hood This beast weighs 3 pounds, which is still much lighter than my Pentacon 300/4 (which is now for sale cheap if anyone is interested). But, I probably won't be hand holding this one either. This first version of this lens has a rather checkered history for Nikon users from what I've read online. The major complaints seem to be slow/noisy AF (hardly an issue on the NEX) and a certain fragility resulting in the back portion of the lens breaking off. Speculation is that it is caused by a combination of a undersized casting and the weight of a heavy dslr creating metal fatigue to the point of failure (again, hardly an issues for NEX users). There are also numerous reports of less than stellar VR performance, but that seems to be an case (cases?) of over-expectation of the ability of the VR in my opinion. Also there are complaints off blurry pictures of a tripod. In my limited trials so far I believe this to be caused by holding the camera body and using your hand to trip the shutter. Using the wireless remote on the 5N resulted in much better results than shooting by hand. Here's a couple example pics until I can get out and really put the lens through its paces. No sharpening applied on the first 4 shots, usual sharpening applied because of resizing for the web on the rest. The chair is 8 inches in front of the strawberry and the picture frame is 16 inches behind it. Wide open (5.6) @ 400mm from about 20 feet And a 100% crop from near the center f/11 @ 400mm And the 100% crop These next two are about 100 yards @ 400mm f/11 These are all shot off a tripod as there ain't no way in hell I can hand hold this puppy. The minimum focus distance is 7.5 feet (2.3 meters), putting my Canon 500D diopter (close up filter) on reduces that to about 20 inches from the front of the lens @ near 1:1 magnification. I haven't tried the extension tubes yet to see what that gets me as a minimum focus distance. All-in-all I'm happy with my purchase so far. I've wanted a lens like this for quite some time but being a Pentax shooter the options were somewhat limited. Now I don't have that problem. More pics as I shoot them.
