For sale, an Agfa Super Intergon. Its marked as 305mm f11 WA. It easily, and very sharply, covers 8x10. It has click stops for f11, f16 (marked) and f22 but will stop down well past there. I've seen reference on-line to the f9, which is much smaller. I've never been able to find anything about this beast or what it will cover. Glass is in good shape. It needs some more cleaning (I wiped it down with a brush and lens pen) but I didnt see anything much on it.

Looking for $125 + USPS shipping.
