<p>Hi all,</p> <p>Can anyone speak to the quality of an older 500mm f4 P on a D800? I understand it's a manual focus lens, and I'd be using it primarily for static shots (no BIF). I'd love to see comparison shots with a newer AF version, but haven't found any so far. </p> <p>I'm currently using a 300mm F4 with a 1.4x, and find the images a little soft and in need of more reach for what I'm doing.</p> <p>Thanks,</p> <p>Steve</p>
