Tamron 90mm/2.8 macro with Canon 50D and Tamron lens

[Canon2010]

Can Canon Macro Ring Lite MR-14EX be used on a Canon 50D with Tamron 90mm/2.8 macro lens?

Can someone please let me know.

Thanks a lot : )

I found this

Attaches directly to EF 50mm f/2.5 Compact Macro, EF 100mm f/2.8 Macro (both versions), and MP-E 65mm Macrophoto Lenses (can also be used with EF 180mm f/3.5L Macro USM via Macrolite Adapter 72C)

So I'd guess that you would need some sort of adapter to physically attach it to the Sigma lens, if such an adapter exists. You might be able to rig something up though. I don't know if it attaches to the lens via a bayonet style mount, like a lens hood....or if it's something different.

Or you could look into the Sigma Macro ring flash
