In this post, we will discuss the adaptation of the well-known and widespread regular non-removable lens T-43 4/40 LOMO from amateur cameras SMENA 8M / RAPID / SYMBOL. I-61, I-61 L/D, INDUSTAR-61 L/D are excellent donors for this custom. As a result, we get a compact lens for mirrorless cameras with M39 thread, MDF about 0.6m, which is quite good.
