But this one's not on any I can find. If anyone's got decent info on this lens' resolution numbers, please let me know where. My lens seem pretty sharp, but I don't have a good way to evaluate its resolution. | ||

You already know that it is a tessar type, has to be stopped down to get good detail in the corners. If you can't live with that and want a 135 your best bet is to get a modern plasmat-type 135. Not a convertible Symmar, something more modern than that. Good luck, have fun, Dan | ||

Why don't you offer him a superior replacement in trade? | ||
