B&H, you have a warning on the DA*300 page stating it is not compatible with full frame. Everything I've read on this forum states that it is.

RICOH IMAGING web site states: The PENTAX DA* series of high grade lenses, designed exclusively for PENTAX digital SLR cameras, features the highest quality components and construction. DA* lenses also feature the quiet SDM focus system, and a tightly sealed weather and dust resistant construction to enhance durability and reliability in rainy or dusty conditions. The focal length is equivalent to 450mm in the 35mm format.

I would imagine using the lens on a film body could confirm coverage. The degree of fall off or decreased image quality past the 23.5mm x 15.7mm APS-C sensor size could be the issue but at this time, I cannot confirm. We list what Ricoh does until such time there is a FF DSLR to test.

The DA* unofficially supports the FF image circle. It's still marketed as an APS-C lens, however.
