The 135mm F/2 Defocus lens is a hard animal to tame. It does take great pictures, but focus is a struggle. I’ve found that it’s best to operate this lens manually, as the autofocus is slow and unprecise. However, it does lead some great photos, like this one of my compact SRAM Red crank.
I got some great news today. Asterisk*Cycles has become an official dealer for AX Lightness parts. AX Lightness makes ultra-lightweight parts for road and MTB bikes, from the 60-gram Zeus stem to the 195-gram rims.
