Macro Test 2

Minus the focus this time, was a bit blur today doing this test as I just recover from fever, flu, sore throat and cough.

Issue with marco using prime lens together with Nikon macro adapter ring are

1) I can only used manual focus
2) lens are fully expose without filter protection
3) aperture need to set at the min f-stop num allowing more light to pass through the lens.
4) I cant get f-stop number reading at my camera as the lens is reverse. I need to turn the dial at the lens for f-stop number change.

As for people who has budget buying a macro lens this is a best way to work but this Nikon adapter works only with 52mm diameter lenses.

Magnification Ratio with different lenses

  • Nikkor AF 20mm f2.8 : 3.4X
  • Nikkor AF 24mm f2.8 : 2.5X
  • Nikkor AF 28mm f2.8 : 2.0X
  • Nikkor AF 35mm f2 : 1.4X
  • Nikkor AF 50mm f1.4 : 1/1.1X
  • Nikkor AF 50mm f1.8 : 1/2X
  • Micro Nikkor AF 60mm f2.8 : 1/1.2X

35mm with adapter ring allow us to reproduction ration x1.6

50mm with adapter ring allow us to reproduction ration 1/2x

just the 35mm lens along result also quite impressive for macro but not as good as Tammy lah!

That's all for this test. Well at least get something out from this test and now will sell away my Nikon Macro adapter ring for RM70 since I already have a special dedicated macro lens.
