KOOKA KK-C68 Pro Auto Focus Macro Extension Tube Set for Canon EOS 5D2 5D3 6D 650D 750D 5D MarkII 60D AF Mount With 12mm 20mm and 36mm Tubes

These came with the Micnova brand name rather than Kooka, but it looks like the same product.I bought these to replace some other extension tubes that I had bought, which fell apart and dropped one of my lenses. Those tubes had metal lens mounts, but inside they had a flimsy plastic construction.So I bought the Kooka/Micnova tubes because the description said "All brass and Metal Construction". It's not. Again the lens mount is metal, but the body is just plastic. So not to be trusted with a heavy lens (like the one the photo of the product shows being used).

Good quality, well made and produced excellent results.

Very nice macro tubes, managed to get some nice close up shots.

great stuff!

all very
