I was getting to grips with my new extension tubes this evening trying them out with a bunch of subjects (everything from Antonia’s engagement ring to 5 coffee beans). I finally settled on my Raspberry Pi (Toni argued the other 2 were more interesting subjects, but the photos were worse).
It is really quite challenging to get a good macro shot at this kind of distance, I don’t envy small product photographers and I have a lot of respect for people who get amazing photos of small insects.
I relied on our living room lights here, so needed 8 seconds of exposure. Even at f/11 the depth of field is super narrow, probably under 2 centimetres.
Here’s my set up for the shot. If you look closely you can see the label indicating the MFD of the lens which is 45cm. The 21mm extension tube (the other 2 are in the background) is dropping this to around 10cm.
For anyone interested here are 2 more shots in roughly the same setup (just with objects moved to obtain focus) with different stacks of extension tubes. Remember the shot above is with just the 21mm.
Lens: 50mm f/1.8 II (with 21mm extension tube)
Focal length: 50mm
Shutter speed: 8 seconds
