Hi Everyone, New here and wanted to say hi. Hasselblad is step up for me. Currently shoot a Lieca MP and a Nikon D70. I'm a classic "old dog" trying to learn some new tricks. I have an 503cw and want to get some lenses. I've been offered an cb80 and a cb160 at a very good price. They are as new-perfect. How do they compare to the "normal' Planar and Tessar??Thanks in advance fo any info. Allan
