Playing with 500mm Moon

Actually the lens were 500mm but with crop factor and internal 2X tele for the A77 and 1.5X CIZ (clear image zoom) for the NEX, effective focal length is more than 500mm.

Lens is AF in native A-mount but on the E-mount NEX F3, basically a MF lens. 500 x 1.5 x 1.5 ~1125mm but image was not at 100% crop. Tough to do with hand held LCD viewing.

This is for a Mamiya 645 500mm lens on the A77. (Oops, should be 500mm in the image text.) 500 x 1.5 x 2 ~ 1500 but image was not at 100% crop.

Good work! I've never managed to shoot the moon handheld like this... Laughing

But since the Bigma is an AF lens (that it was used manually does not matter) I have moved the topic to the Autofocus Corner.

Great results, especially for hand-held. I've shot quite a few photos of the moon with an old 500mm refractor of mine, which provides images of similar sharpness. But I've never tried doing it hand-held. With my crop-body Canon, the effective focal length is 800mm. But I shoot at ISO 100 (because the camera adds noise to images above that level), and expose at 1/125 second at f/8. No way would I expect 1/125 be sufficient with an 800mm focal length. So I'm guessing 1) you were shooting at an elevated ISO and 2) your camera handles high ISOs much better than mine does. Cool
