DIY macro extension tube, album created on August 6, 2017
The Takumar-A 2x teleconverter is a mediocre teleconverter, but is easy to de-glass and makes for a decent extension tube... Some photos of the surgical procedure involved, and a couple of test shots with the Pentax-A 50/1.7 - not itself a particularly close focusing lens. Looking forward to trying this with the Tamron 70-200/2.8, my only decent somewhat-macro lens.
