I wanted to take some still life close-up shots a little while ago but, not being what I normally shoot, I didn’t want to invest in one of the superb Hasselblad macro lenses. The solution I settled on was to use the 80mm Planar mounted on a 55mm extension tube.

This setup got me more than close enough for what I needed while still remaining fairly manageable (I discounted using bellows because of this). Focusing is a little tricky as you lose a few stops of brightness on the ground glass screen with the extra extension, but this wasn’t an issue in the studio where I have plenty of light.
