p.1 #1 · p.1 #1 · Playing with a Meike MK-C-UP multifunctional extension tube


First few goes with this adapter which can either be used as an odd electronic extension tube or as I was using a lens reversal adapter that maintains full electronic control of the lens. Tried it with the kit lens. One oddity I noticed during shooting with ETTL flash was the shots were around 1 stop overexposed at my normal flash settings. I think this is because the reversed lens has an aperture around one stop wider than the set aperture. This means needing to shoot with the aperture on the lens about 1 stop smaller than you would normally at any mag and also setting the FEC on the flash about 1 stop -ve to your normal setting.
Mag range with the kit lens was just under 1:1 at 55mm and about 5:1 at 18mm. I hadn't expected to get focus at that focal length but the focus distance was 25mm in front of the adapter ring.

Slightly longer review with more test shots here

The setup




Magnification - min =0.86:1


Magnification max =5:1.


Single shots at min and max mag

Brian,

Being able to focus at full aperture (shallow DOF) should increase the chances of hand-held images being in focus when the aperture is at the selected value (deeper DOF) during exposure.

This seems really awesome! Unfortunately there doesn't seem to be a Nikon version. Anyone know an equivalent device for Nikon?

This has only recently appeared for the canon system - maybe a Nikon one is on it's way ?

That would be awesome. Keeping my hand on the aperture lever and getting inconsistent exposures, plus a darkening viewfinder were the only things I didn't like about using my kit lens reversed. This would solve all of that.
