The full size samples are very helpful, thanks a lot... Sure, the conditions aren't the most flattering for sharpness testing (flat low light) but your conditions and settings are realistic for a lot of wildlife encounters (I don't mind bumping up to higher ISOs to get faster shutter speeds than 1/focal though). In my judgement the sharpness looks about the same as my average 100-400 copy, and will probably take about the same amount of processing to look tack sharp (which is understandable at this price point). I imagine with a high end prime at the same focal lengths at 100% you can tell exactly where the focus point was and get more fine fur definition than these samples show, so it will be interesting to see comparison shots, even though the primes and 200-400 are out of my price range.
Also reminds me why I like to shoot bears at f8 when there's enough light, to at least get the tip of the nose all the way to the eye in focus so in a large print it looks natural like the bear is right in front of you. The sharpness and noise usually isn't pretty at 100% but looks amazing in print form, so I understand that these slightly soft photos are still quite good and pixel peeping is only useful if you plan to print big, which I do (my portfolio size is 12x18 and I print up to 30x45").
Thanks again, there's a lot to think about and consider!
