Many thanks in advance

Think you'll find the same from anyone using that lens, Mark. Zoom lenses never work very well for macro (or I've never seen great results and I've tried a few) and I gather IS is not very effective at macro distances (but think that's on 1:1 macros)bugmadmark wrote:..... and just he one lens , a Canon 28-135 IS USM - but just cant get sharp macro shots on it......... It would be nice to hear from other 400D users how they are getting on with the 150 on this body, and also, if they have the same problems that i have using the 28-135 at its macro end.

I believe they do make Tamron for Canonista's - tho' I'm happy with my Tamron 90mm f2.8 macro on my Nikon. (With cropped sensor-size it is effectively a 135mm macro).Rogerdodge wrote:Firstly, congratulations on being a member of the Canonista.
(Can't win them all I suppose! N)
I have no experience of the Tamron or Tokina, but I bet they are pretty good - as all specialist lenses like this will be.
