A comment on one of my YouTube videos spurred a debate with a friend: What type of lens works best for a reverse-mount macro? This video tests various lenses from 24mm to 200mm to see how well they magnify an Australian $2 coin. In fact, the video opens with a photo from the best performer. You may be surprised by the results. Some of the results certainly surprised me.
Reverse-mounting a lens for macro use is pretty simple, with an adapter. For about $5 (USD), you can pick up a new, bargain-basement reverse adapter ring on eBay. That can serve you pretty well for a LOT of macro work.
The lenses I used:
Nikon Nikkor-Q 200mm 1:4
Nikon Nikkor-Q 125mm 1:3.5
Nikon Nikkor-P 105mm 1:2.5 (this wasn't tested, unfortunately, due to a best filter ring.)
Canon 100mm 1:4 (1:1 macro) in FD mount
Sigma 50mm 1:2.8 (1:1 macro)
Takumar 50mm 1:1.4
Tokinal-EL 28mm 1:2.8
Canon 24mm 1:2.8 in FD mount
Nikon Nikkor Zoom 43-86mm 1:3.5
Nikon Series E 36-72mm 1:3.5
