In March 2023, I backed the SeeAir Tankless Dive System on Kickstarter. Compact, battery-powered underwater breathing gadget. Polished renders, a slick video, spec sheets that looked legit. $362 for the dive unit and a couple accessories. Seemed fair.

In this post abuot manual focus lenses on DSLR cameras, we'll again look at a M42 mount and a FD mount lens. (be sure to check out the first and second post). The M42 mount will be my Miranda 28mm f/2.8 lens, while the FD mount lens is Mogens' 35-70mm f/2.5 FD lens. Again, notice that these are very fast lenses that have cost less than $40 a piece.
