[M42 Lens] Pentacon 30mm F3.5

Using Sigma SD14, we can use only lens of Sigma, as Sigma is the only manufacturer of Sigma SA mount lens. But we, owners of Sigma's SLR, want to enjoy this great camera not only with limited lens but with a huge variety of lens. That's M42.

In the past, I couldn't get a mount adapter for Sigma SA mounts in Japan, and gave up hope to dabble in M42 lens. But I realized that I can get SA to M42 mount adapter at Ebay easily. So I bought two mount adapters and two M42 lenses. Today a lense and adapters were delivered.
