Thanks for the tip sylvester!
Does anyone know how to get ISO 100 on the 40D in M? I must be retarted because the lowest mine goes is 200 and then it hits auto. I have looked in the manual and it says it is capable of 100 but I can't figure out how to set it.
I was just looking at a pdf for the 40D, and it says that iso is fixed at 400 in M!?! Why the hell would they do that? Isn't the point of Manual that you have FULL control!?!
Definitely interested to hear from other 40D owners, as i want to get one at some point.
I think this the one that has been asked many times when the 40D first came out! Look up the setting Hightlight Tone Priority and I think you will find it "on", set it to "off" and see if that sorts it out???
If not that then I blame a senior moment and the HTP setting has another irritating effect

HTH

It is not set to 400 ISO in M, that is the "Auto" ISO setting . If you have hightlight tone priority on you are unable to select ISO 100 nor ISO 3200. I worked this out after a week of wondering where ISO 100 had gone lol.
