Hard to believe that the photo you show was taken WIDE OPEN AT F2 at 200MM...will that lens take a tripod mount?

Yes... it's spectacular in a word. Out of some over $200,000 worth of camera [url="http://www.flickr.com/people/genotypewriter/"]gear I've used[/url], this is the absolute best lens:

Here's the setup (200/2 IS + Nex-5):

I do not share your pessimism about the Nex AA filter, because my raw images taken with apochromatic lenses such as the Tokina 70-210 SD II zoom at 70mm/F8 and smaller show single-pixel-width features. Don't see how it could get any better. Or put another way, it seems like the AA filter is just about right if it doesn't get in the way of single-pixel feature capture.[/quote]
Whoa there... hang on a sec. The 70-210 is no real APO lens... people kill for real APO lenses. Just because you can see 1-pixel details it doesn't mean the lens is APO. Here's a real APO lens:
http://www.jenoptik-inc.com/coastalopt-standard-lenses/uv-vis-nir-60mm-slr-lens-mainmenu-155.html
Even though it's just a 60mm f/4, the designer had to use like 4 [url="http://en.wikipedia.org/wiki/Fluorite#Uses"]CaF[sub]2[/sub][/url] elements and price it at $4500 because it's a real APO lens. Other real APO optics include high quality astro telescopes like [url="http://www.optcorp.com/product.aspx?pid=1-637-1002-7455"]Takahashis[/url], [url="http://www.astro-physics.com/index.htm?products/telescopes/130-gt/130-gt"]Astro Physics[/url], etc. I repeat, some 70-210 is not a real APO lens. People struggle to make primes APO... it'll really be a physics-defying cold day in hell if a zoom is ever corrected that well. FYI even the $3500 [url="http://www.bhphotovideo.com/c/product/162726-USA/Leica_11884_90mm_f_2_0_APO_Summicron.html"]Leica 90mm Summicron-M (f/2) ASPH APO[/url] is not really APO.
Oh btw... Where did I ever mention anything about an AA filter here? <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='
