| | | Ebay AF macro extension tubes.
Has anyone got any experience with the 'new generation' of macro extension tubes now available on ebay? Something like this: linky
They are a lot cheaper than the kenko ones, but do seem to still have the relevant connections. Has anyone got any comments? Do they work as well?

I bought some Kenko tubes for not much more than these

I use Nikon, and unfortunately there is nothing in the UK for less than £100, there is a £90 one but that's Hong Kong, which I'm not mad keen on.
The one I've linked looks pretty good, it's apparently metal and has the connections, and is a lot more realistic price for something with no glass!! I'm thinking of asking for it for my b'day so I may take a punt... I'd be more confident if someone had a good experience though!

I have to say that the Kenko are superbly made and worth every penny.

I wholeheartedly agree with nightshade. I regularly use Kenko extension tubes with my Nikon 105mm Macro lens - in fact the 36mm is almost a permanent fixture and so far (touching wood) I've not experienced any problems whatsoever. Without counting that's well over 10,000 shutter actuations with various combinations of tube length.

Well, after a lot of procrastination (not helped by the possibility of a 180mm sigma for £299 from Jessops.... false alarm!!) I took the plunge and ordered them. They arrived yesterday and, well, they seem OK.
They're solidly made. I don't think they are all metal like it says, which i will query, but they're certainly metal mounts. They're rock solid on the body and lens, meter fine, fully auto and the AF is OK, hunts a bit, but I think that's to be expected, and like most people I focus manually by moving the camera with macro at this scale anyway. When you are focussing manually on non HSM/ AFS lenses it is a bit noisy while all the 'screwdriver links' rattle around, but not a major issue.
With my Sigma 105mm macro it gives me roughly 2x mag, it works great on my big lenses to bring the focus in close (as I presume any other tube set would!)
One thing which is a bit weird is that they are lined inside with a sort of felt. Whilst I'm sure this will stop any reflections really well, I'm a bit concerned it might be a bit of a dust trap. I'll have to watch it carefully.
All in all for £60 (especially as it's a pressie  ) I'm pretty chuffed, I'll be playing around now, I've got plans for some scenic frost for this years christmas card!!!
I'll keep everyone informed re long term durability...

As a quick follow up. I've noticed when using the pop up flash, or a hot shoe mounted flash, I'm over exposing by a couple of stops, presumably because the camera thinks I'm further away than I am. When using the flash off camera it's fine (which is how I usually use the flash for macro).
It seems pretty easy to correct but is this the same for all tubes?
