Extension Rings for RZ (again)

[catem]

I made a post some time back about extension rings - yet another thing I haven't yet got around to sorting - but am looking to use them for something I want to work on very soon. I'm looking for Mamiya RZ rings (established RB rings won't function on the RZ) probably second-hand.

I'd value comments from anyone with experience with these - whether it's sensible to get one, or both, how useful/successful you found them in particular.

Thanks!

edit- am looking to use them with the 110mm lens

How much extension do you need? Rings for the RZ aren't any different then any other camera. Just empty tubes.

Good point - I'm asking 'how much' and the answer is 'how much do you need...'

I'm not certain how much at present - I suppose I was hoping to clarify quite how close in the 2 different tubes available would get me, (either alone or in combination) with that particular lens.....

Any experience people have had with/opinions on the results with would be useful.....

Do you need to get close? Or do you need magnification?

The chart only goes up to the 127mm. You could do the math for the longer lenses.

Thanks a lot Nick, helpful info.

Any subjective views of own results from anyone???

Without getting into too big a discussion about how results compare with a for-purpose macro lens (not a possibility at present) I was interested in hearing peoples' views on their own results from a particular combo using the 110 lens.

I have experience of using extension tubes with 35mm so understand some of the drawbacks/benefits of using them.

Catem,
I use ext tubes on my RB all the time, I consider them a neccesity. It's rare when I take the RB out in the field that at the very least, a #1 ext tube isn't packed, I use the 180 with the #1 tube to give me a more natural perspective as well as more working distance.

Does a RZ have a focal plane shutter?

A RB's extension tubes are NOT just empty rings. Think about it. I suspect a RZ's are the same, only electrical.
