But even with that cleared up I still am not sure I understand it. I certainly appreciate that there are differences between a Planar/Xenotar or a Tessar/Xenar lens but, having used both myself, I personally prefer the look of the Tessar. I think people are drawn in by the numbers rather than the image quality.
You may be right---there's certainly a name cachet to the Planar. And I have to admit, I just went and looked at my 'flex (Planar) and 'cord (Xenar) images on Flickr in adjacent windows, and the differences were less than I expected; but the Planar does that "dead sharp and clinical" thing, and when that works, man, it really works. There a handful of images in each group that simply couldn't have been taken with the other lens.
Conclusion: Get one of everything!
