Sigma 50mm f2.8 EX DG Macro Lens + EM 140 DG Macro Flash

Hi all,

I'm planning on buying the Sigma 50mm f2.8 EX DG Macro Lens soon, and I'm wondering if Sigma's EM 140 DG Macro Flash would be a good partner for it. I haven't bought an external flash before, and to be quite honest I have very little knowledge about them, but I'm wondering, would this Sigma EM 140 DG Macro Flash only be compatible for use with sigma lenses? Or for example, would I be able to use the Canon Flash MR14EX with a Sigma lens?

What I'm simply asking is:

1. Would a macro flash be necessary/useful for me in combination with the Sigma 50mm f2.8 EX DG Macro Lens?

2. Would a Canon macro flash be compatible with a Sigma lens, and vise versa?

3. What are the differences between Sigma's EM 140 DG Macro Flash and Canon's Flash MR14EX, and therefore which is 'best'?

Thank you for any help!

Anyone?

You also posted the same thing in the lens forum. I would suggest deleting that one and giving this one a little time for someone to respond. Or, you could delete both and repost in the "macro talk" section.

Either way, give it some time !

Sorry! I initially thought this forum was only for studio lighting, etc., but after having a closer look I saw that it wasn't, hence the double posting!

How do I delete this thread? I'm going to post this up in the macro section for now, which I guess is the correct forum for it, and hope that a mod deletes this one. I'm not able to do it myself, am I?
