20 x 24 Lens Guide
The following table is a list of "classic" lenses which one can find on the used market, all of which have some usefulness on 20x24 cameras. While some are obviously going to be hard to find (as indicated in the last column), some are readily available. We can help you find such lenses on request through our network of dealers and associates.
We will be adding certain recent production lenses to this table in the near future (posted 4/30/99)
