Hello everyone,

much has been said (and read by myself) about the many different 90mm lenses. However, since I'm about to buy my first 90mm lens I was wondering which of the following ones you would choose ...

- Rodenstock Grandagon 90mm f/4.5 MC
- Rodenstock Grandagon-N 90mm f/4.5 MC (might be too expensive though)
- Rodenstock Grandagon-N 90mm f/6.8
- Rodenstock Grandagon 90mm f/6.8
- Caltar II-N 90mm f/4.5 MC

They're all within my budget (300-400$).

Any help/thoughts/recommendations are highly appreciated.
