Super macro

For this week’s Photo Challenge we have to take a mystery macro picture. It’s supposed to be obscure, and then there will be a guessing game before the zoomed-out versions of the entries are revealed.

Super macro

I won’t say what this picture is of, but I’ll say a word about my macro equipment. I have a Tamron 90mm f/2.8 macro lens which is capable of producing a life-size image of the object on the sensor, known as a 1:1 macro lens. I didn’t use that.

Instead, I used an old, Soviet lens (a Helios 44M 58mm f/2.0) attached to my camera via some leather bellows which can be extended as far as 15cm. This gives around 5x magnification, so you can fill an APS-C sensor with an object that is only 5mm wide. It sounds good, but the flip side is that you get extremely shallow depth of field (fractions of a millimetre!) and that you throw away almost all of the light that the lens transmits. You need a lot of light to make this work – especially if you stop down to improve the depth of field.

The picture above was taken at ISO400, f/16, 30 seconds. I decided not to use a flash but rather to set up a very sturdy tripod (and shut the kitten in the other room, because she likes to attack my tripod’s carry strap).

  1. Nice work! I’m watching some old lenses on eBay at the moment for this very reason!
