Ok, after a few more days of use, I have quickly fallen in love with this lens. My in focus rate is extremely high (about 95%), and it's optically stunning. Great color, and really, really good bokeh.
Beautiful shots of your daughter, especially the one from 10 Feb. Makes me almost wish I had the CZ 28-85/3.3-4. Then I remember how good my 24-70L is, and I go out shoot with some Leica primes. Man, it's tough being an alternative shooter.
That one was from Feb 9, thus the confusion...the only pics I posted on Feb 10 were the ones of the thistle and a dog statue....which is why I said 'what are you trying to say.'
So, while I love this lens, I noticed that the little haze marks on this copy seem to have a spidery look to them, and so I was worried about it possibly being fungus (with no way to clean it)...so I called KEH for a return, and this one's going back, but I got its replacement today (an EX graded one). This one looks absolutely mint, save for a slight yellowing of the numbers marking the focal lengths (the aperture numbers are bright). Other than that, absolutely perfect. Perfect glass, perfect finish, perfect damping, perfect zoom action. Frankly, I have no idea how this is not a LN or LN- grade...what would make this not an EX+?
Anyway, optically it appears to be roughly the same as the other one from about 35-85mm (which is great). The thing is, the new copy is significantly sharper at 28mm. The old copy was acceptable wide open at 28mm, and fairly good stopped down. The new one is very sharp wide open and prime-like (save for the very, very corners) stopped down a bit. Very pleased.
This is just a fantastic zoom lens. Easily as good as my two Canon L zooms, and easily as good or better than the 24-105L and 24-70L optically (of course, minus AF and IS, in case of the 24-105). Much happier having this, though, as I saved myself at least $700.
