Can someone recomend an extension tube set that actually works?

I've bought (and returned) five sets of extension tubes, all work individually but none seem to want to work when stacked!

I admit they've been the cheap ones, so caveat emptor and all that, but before I go looking for yet another set - any recomendations?

I have some Jessops tubes from my Canon days that were cheap and worked perfectly even when stacked - not sure how much that helps though..!

I was after some M4/3 automatic ones.... so that all the focussing worked through them, there's a massive difference in price and the expensive ones don' LOOK any different/better than the cheap ones, so I don't know how to find some that work other than ask for help!

PS been out with the new camera and your old lenses a couple of times now... really enjoying them - thanks!

Mine are fully auto - no idea if there are any for M4/3 though..

Glad you are happy and enjoying the lenses - it helps when looking at the bank statements..I've just got me a Nikon 70-200 f2.8 so all the money I got from you have disappeared on that !

Hi there Walti!

If you have a look at post 30 on this thread http://e-group.uk.net/forum/showthre...t=28900&page=2 you will see Alf using stacked Kooka tubes, with the fairly heavy sigma 105 hanging off the front on an 4/3 to m4/3 adapter.

From memory Alf got a set of three of these tubes and does use them all at the same time - they might be worth googling to see if you can find a set for an acceptable price.

I hope this helps - I'm sure that Alf would answer any questions you may have about them if you asked him.

Cheers,

Ralph.

Re: Can someone recomend an extension tube set that actually works?

Some time back I read that you cant stack teleconverters as they have a system that detects what is attached to the camera (for firmware update purposes)

But tubes I would expect just have a simple electrical pass through system. Are they all fully locking on to each other ?

I have the expensive m4/3 Kenko tubes. They do work with m4/3 AF lenses and they will stack.

Best with prime lenses: Be aware that quite a few zoom lenses don't work with tubes.

Re: Can someone recomend an extension tube set that actually works?

Hi I have a cheap set of eBay I think they were 19 Inc postage its a set of three 10mm 16mm and 20mm for m4/3rds with all connections and work brilliantly, I have had all three attached at the same time with no problems.
Only thing with all fitted is hand holding very difficult to hold steady enough to get sharp focus due to shallow depth of field.

Some Panasonic cameras will not accept 3 stacked tubes accrding to the info I got with my tubes.

I use these Fotga extension rings on M43...work fine both individually and when stacked.

Re: Can someone recomend an extension tube set that actually works?

Hi, don't know how a camera can tell if more than one is connected as there is no chip or other electronic in them, it is just a straight through connection, unless the carmera can detect micro drop in voltage or milli amp's.
Just a thought on why there maybe a reason for non multi tubes, might be of poor quality connection in some manufactured products.

we get what we pay as they say. I'm sick of all the cheap Chinese knock offs but then our money talks; and the less money we have the louder it seem to yell "the cheapest will do"

When/If the time comes for tubes I would go with Kenko .......... still have the 60mm Sigma and tubes in mind but atm I have a 12-40 to play with. (will get it this week sometime)
