I find the 72mm adaptor for my 150mm Sig, no one on the planet seems to have it. Maybe I can fabricate something.
As good as the MT-24 is on the MP-E I don't like it on longer lenses....I can fit it on my 100mm but never do. I've never even wanted to put it on the 180mm.

I tend to use the MR-14 with the longer lenses but my old 550ex has it's uses too (mostly as a slave).

Maybe the reason nobody has the adaptor for the Sigma 150mm is that putting a wee twin flash on it is not the best idea? On a lens with a long working distance a flashgun on a bracket either side of the lens seems like the best solution to me....big lens = big flashes.

We will see how it goes. With the power rating of "72 (feet) / 22 (m), at ISO 100 (with both tubes firing at full power)" and the proper settings, I would like to think that the extra 14" or so of MFD will not impact its ability to work at 1:1 or slightly less with the Sig 150mm. At 5:1, f11, 1/250 sec and ISO 100 the MP-E 65 has an effective aperture of f66. The MT24 with Slo Fen difusers works so well that I have to dial the power back a bit.

The adaptor has been back ordered for over a month, it sells so fast that it never stays in stock, and now with what just happened over in Japan it looks like it will be a long wait for the next shipment. I'll look in to the feasibility of making one this weekend and post the results, if I can find the adaptors to modify.
