There were some questions regarding the use of extension tube(s) vs reversing of a lens, so I decided to do a small review to help you people out. As I have limited number/sizes of ext tubes, the 2 shots could not achieve a 100% identical reproduction ratio.
Shot using Nikon 50/1.4 AFD @f11, auto white balance. Straight out of camera (other than resizing/cropping).
Using Kenko Extension tubes 20mm + 36mm.
Lens reversed using BR2A - white balance seems off.
Ext tubes @ 200%
Lens reversed @ 200%
Please discuss ....
