Re: Another problem with the 40D +TC+100-400L IS

That problem is on the 30D to!

I started a discussion in a swedish forum some months ago about this but no real answers.
It is in swedish but you can always look at the pictures...

30D, Kenko PRO 300 1.4x and/or 2x and IS does not work unless the lens is fully open. At 5.6 it works as it should. I had hopes that changing to 40D would take the error away, but no. Same problem, so this week I bought a Canon 1.4 instead and now it is working.

Edit: I noticed that I had the same problem on my 400D but not on my 300D.
