Here is one of my most precious lenses, or, the second iteration of.
This is simply an old 50mm lens stuck inside BMW engine tubing (other unnecessary commuter car brands are available).
To the other end of the tubing I’ve super-glued the mount of those cheap extension tubes you buy for macro photography.
The whole thing is pretty easy to use once you get your head around focusing. I’m not going to get into how it works, I might do a tutorial on that at some point.
The lens can be used for some macro, though it’s not at all ground-breaking in that mode.
I use it for portraits and, most of all, “street” shots, to get an abstract perspective.
Again, not much point explaining – 3 examples up tomorrow!
