OP, Carl Zeiss optics means nothing. It's just branding. Since computers started desigining lenses fifty years ago, every company has the same knowledge and abilities. I have a Ricoh 50mm that sharper than the same Pentax. Not just mine, but the lines. Some better, some worse.
I'm waiting for the TMO 640, too. The only thing lacking in the 810 that caused me to start down a long, frustrating, disastrous road was WFC. And that TMO put WFC in that bottom dweller 525? but not the 810?
