[QUOTE="brocknroller, post: 1728183, member: 665"] Jerry, Glad you enjoyed my journal article parody. I didn't want to post it yet, because it's still out for peer review with Moe, Larry, and Curly. :-) I hope it did not offend BF techies who either do this stuff for a living or for the sheer fun of it. I used to edit medical journal articles and turn doctor's technical notes into journal articles, much of which involved turning passive sentences into active ones and eliminating pedantic phrases such as "In point fact". To address Alex's points: I have often wondered about the same thing. If a bin user can't see CA, does that mean he can't see subtle shadings of red on a male Cardinal or the goniochromism on a Mourning Dove's neck? Even though "bench testing" put the 8x32 LX only an element behind the 8x32 SE (or half element, I forget which, Steve recorded the test results), in actual practice in high contrast situations, the LX falls farther behind in resolution of fine details. Matched against an ED glass bin with a longer FL, the difference becomes even more noticeable. For example, I compared the 8x42 Promaster Infinity ED to the 8x32 LX at a park on a bleak, winter's day, watching two back lit hawks on a tree branch. Looking at the park lawn and shrubs and the caretaker's John Deere tractor, the view through the bins looked almost indistinguishable. Both bins not only had similar contrast, color rendition, and color saturation, but while well braced, I could resolve small print equally well on the tractor and the park rules sign. However, when I trained the bins on the back lit hawks (also while braced), the 8x Promaster "clearly" resolved more detail because the LX's CA created color fringing (on the tree limb and the birds), which diminished the amount of detail I could see on the hawk's talons and feathers. This is why I take "bench tested" CA resolution results with a grain of salt including my own. The true test of a bin's CA control is best evaluated "in the field" under adverse conditions. That's where CA and other aberrations are more likely to rear their ugly heads. Having said that, in fair weather, the views through the 8x32 LX are very impressive. I get "niggly" about the astigmatism on top of the field, the shallow depth of focus, and the "poor" ergonomics (for my big hands), but these are idiosyncrasies that others will ignore, or in the case of ergonomics, might see as an asset. Regardless, come winter, I would prefer an ED bin even if it's only "good" rather than "great" bin. [/QUOTE]
