The 500mm mirror at twilight... with the squirrel

[DrEntropy]

Trying to work on hand-held shots with this mirror lens. These were with the ISO at 1250, 1/250th. Lens is a fixed ∱8. Used GIMP to lighten them a bit. DoF is really skinny at this distance, about 25 feet away.

EDIT: On seeing these, Mitsy says she's named it "Elliot."

Didn't know you had another! Very good for hand held at that focal length (especially #2). The bokeh has the same or very similar double exposure look to it that the copy you sent me has. Is this one also manual focal only?

 

[DrEntropy]

Same focus, manual only. Fixed ∱8. With the APS-C sensor it works out to a 750mm and around ∱10~11, so not much hope with twilight lighting.

That "double exposure" look is a characteristic of the mirror optics. Two reflections when an object outside the focal point hits the focal plane of the camera.

This one is a Nikkor-C version, got it from a seller in Japan for "skinny money" a while ago. The shots of the cell tower with a juvenile osprey were taken with it, along with the other birds in that thread.

That would explain it. I think it's kind of a cool nostalgic look.

Tripod mounted and with good enough light to use higher shutter speeds, they can be remarkably sharp. The cell tower in that prior thread is a good example. And the birds were all hand held shots.
