Sundial, C16, ashlar, baluster form with fluted upper half. C18 brass sundial on top, signed Thomas Wright. Nikon D700 and Nikkor 28-80mm f/3.3-5.6 G lens.

Photographed with a Nikkor-H Auto 85mm f/1.8 lens on a Nikon D2Xs. 100 ISO. This Nikkor-H Auto 85mm f/1.8 lens was made circa 1971. Nikon never provided these lenses in Ai configuration and their production run was terminated in 1977, having been available in F mount from 1964. Alas! Now the F-mount has gone; the Single Lens Reflex is also deceased. A Golden Age has ended. The glory of the incomparable engineering is eclipsed by electronics.

Nikon D2Xs and Nikkor 50mm f/1.4 AF-D lens. 100 ISO, where the D2Xs excels. Still a bit of post processing, though. Nothing is perfect.

Canon EOS 30D + Chinon 55mm f/1.4 lens.

Nikon D700 + Tamron AF 70-210mm f/2.8 SP LD lens made sometime between 1992 and 2003. ISO 1600; f/2.8; 1/1000; focal length 72mm.

Nikon D2Xs + Tamron Di II SP AF 17-50mm f/2.8 XR LD Aspherical lens.

Nothing much to do with Pythagoras, but that triangle in the foreground is compelling, notwithstanding that it's a bit ragged on the longest side. Anyway, for reference: The square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. Canon EOS 40D + Canon EF 35-135mm f/4-5.6 lens.

A completely accidental photograph which occurred during the course of preparation for cleaning the sensor of a Fuji S3 Pro. I uploaded it simply because I liked the geometry, texture, and reflections. The sensor clean was almost a success. There's still a blob of crud over on the right-hand side, where the sweep of the swab terminates. You can't see it in this photograph, nor a good many others. I'll tolerate it for a while. If you can get a photograph like this by shooting through a window pane - and I haven't given it any software assistance, this is SOOC - what does it tell you about dirty lenses, etc? I doubt you need to be over-fastidious.
