I’ve been addicted to Macro photography for a long time. For as much as I love it, the normal methods tend to get boring. To make things more challenging I decided to reverse my lens. I was using my A7R Mark1, Panasonic G9 and adapted/reversed a Nikkor 55mm 2.8 macro on both cameras using F-m43, and f-Sony E adapters. A cheap (2.99) bower reversal ring was also used.

Focusing can be difficult with this method, bright lighting causes severe glare on the rear element, and flash is almost impossible to use because of short working distance. My solution is to drag the shutter and use minimal ISO to avoid noise.
Using a long exposure in this way with natural light can bring out details that might be missed in a studio setting.
