Vivitar Macro Extension Tube Set (Set of 3) for Sony A

Comments about Vivitar Macro Extension Tube Set (Set of 3) for Sony A:

I have the same issue as Todd with the 13mm tube, it cannot stop down the lens because the aperture arm does not move freely like the other two larger tubes. At first I thought they were working fine and I just needed more experience using them. Turned out that whatever aperture I set, it was staying wide open causing over exposure and extremely narrow DOF. Compared to the price of the competition though, I can live without the 13mm tube, but I can't give it a high rating.

Otherwise, construction feels cheap but is adequate and the two tubes that do work for me do the job as well as a more expensive brand would.

This is not a good product, the Iris-puller-ring is too heavy for the camera to operate properly, the return spring of none of my lenses are capable of returning the aperture too.
I now have three extension rings that only operate at full aperture.
Sadly, return cost from Norway is too high for a refund to be useful.

The set I received do not work right. Only the 13mm tube is fucntional with my lenses (Tamron 60mm F2 Macro and a Sony 35mm F1.8). I have a Sony A55.

When any of the other tubes are attached, either by themselves or in any combination, the aperture of the lens will not close.

Also, the fit does not feel good. Very tight attaching and removing, not a precision feel at all.

I am not keeping the set I received.

This extension tube set fits and operates well for a lot less money then the name brand sets.

When I got these the little metal apeture control arm in the smallest ring had too much resistance. The return spring in my lenses could not push it, making any picture be at the fastest f/stop regardless of setting. I popped out the ring the arm rides on with a screwdriver. Technically, I broke the prastic flanges the ring rode in. But now it works great. The other two rings worked fine, and now the smallest one does too. I don't know if mine was defective or if this problem was a design flaw (I would bet it was a problem with only mine since if all of them were like this none would ever work). The ring I had trouble with was constructed differently than the other two due to it's smaller size. I thought graphite would fix it but didn't want carbon powder in my camera. If you buy ext. tubes hold them with your fingers on the outside of tube with either hole pointed at your palm and rotate your wrist back and forth. If all the aperture arms flick back and forth freely then they are good. If any won't move freely when you do that then your lenses sping can't move it. Even if the lens can move the arm if it can't do it fast the aperture won't close before the shutter opens.
But if the one you get works fine then these are perfectly servicable ext. tubes. And I will not hesitate to order from BandH again as I am sure they would have taken them back had I asked.
