Mounting a Canon MR14ex ring flash
Hi guys, I was wondering on the compatibility of the MR14 with non canon
lenses. I have the Sigma 50mm EX macro and was wondering if it was possible to mount the Canon ring flash to this lens. Does anyone use this combination? Thanks -- rda |

"Bill Hilton" wrote in message Probably not ... what is the filter size for the Sigma? We use the MR14 and it fits on the Canon 100 f/2.8 macro, sliding into a groove. This lens has a 58 mm filter size. The MR14 won't fit the 180 mm f/3.5 L macro directly but Canon sells an adapter that screws into the 180 (which I think has a 62 mm filter size, or is it 67 mm? can't remember and am too lazy to pull it out and check, so you need to look this up before buying) ... this adapter lets you mount the MR14 properly to the 180 macro. So if the Sigma 50 has the same filter size as the Canon 180 macro (which I doubt) you can probably attach this adapter and mount the ring flash that way. Thanks for the info. The Sigma 50mm has a 55mm filter thread. Maybe then I could get a 55-67 step up ring and then the adapter for the 180 macro. Ill have to wait and see as its too late and I bought the mr14ex on ebay. Didn't think about mounting the thing till it was too late. -- rda |

I can test this out for you later today or tonight, I have a 58 - 67 mm step up ring and I'll see if the 180 mm adapter ring will fit this ... looking at the B&H web page with info on the converter it sounds like it should work ... if it fits and I can mount the ring flash on another non-macro lens then you should be able to do the same with your Sigma with the 55 mm thread. Will try this out later and post the results. Bill |

Didn't think about mounting the thing till it was too late. Canon makes Macrolite Adapters in 52mm, 58mm and 72mm (the filter size of the EF 180 Macro). B&H sells them: http://www.bhphotovideo.com/bnh/controller/home?ci=22&sb=ps&pn=1&sq=desc&InitialSearch=yes&O= SearchBar&A=search&Q=*&shs=Macrolite+Adapter&image .x=3&image.y=8 -Dave |

"Bill Hilton" wrote in message That's a good link ... the original poster would probably be better off with the 58C since it's half the price of the 72C and probably a 55 - 58 mm step up ring is easier to find and carry. Thanks loads guys. I have just ordered the 58C for £3 ! and a 55-58 step up ring. Thanks again -- rda |
