This is a short post showing the macro performance of a Takumar 55mm f/1.8 m42 lens when a 16 mm extension tube is mounted behind the m42 to NEX adapter. With this combination I was able to focus down to about 4 inches away from the objects shown in the pictures which I found around the house and garden. The majority of these shots were taken at F/1.8 to emphasise the shallow depth of field and I carried out my normal Lightoom processing steps.
