I constructed a pinhole lens a few months ago but wasn't happy with the smoothness of the pinprick hole, so here a second attempt. It comprises a body cap with 4 mm hole drilled through and then a piece of foil with a pin-prick hole taped to a circle of black card and this taped onto the body cap (see last image). We visited Grantchester in very changeable weather - here a few of the results. It produced very vibrant colours and the characteristic soft 'focus'. There was considerable flare if I turned at all towards the light. The worst feature is that it focuses on every speck of dust on the sensor so cleaning up the images is very time consuming. Now for some more creative subjects!!
