Hi All

Hopefully this is a simple question! Is the nn5 compatible with a Canon 5d mark2?

Having saved all my pennies last year, I am now the proud owner of a Canon 5d mark 2.
I thought it would be simple, oh no! First of all my copy of Photoshop CS3 would not open the raw files, so I had to upgrade to CS4. I have just put my 8mm sigma on and mounted it to my nn3 and it is impossible to take the zenith shot, it does not physically fit!

I suppose I should of thought a bit more really (LOL) Would a NN5 be better for this for this camera set up?

Thanks

Will
