Canon 100 mm w/ TC + Diopter

Hi folks,

If I use my canon 100mm w/ a 1.4 TC and a canon 500D close up lens, will it be able to focus automatically or will I need to focus manually?

Cheers

Daniel

I've used this combination quite a lot with the 7D, 40D and 50D and had no real issues with autofocus other than it is a little slower than the 100 macro with no teleconverter.

Edit: I'm using the older non-IS version of the Canon 100 macro.

Daniel,

I think from what i have read it depends on which 100mm lens u have. The older version with no IS works fine, if a little slower with a TC, but the IS version doesnt seem to work with AF with a TC.

Im sure others with this setup can clarify, but thats what i understand from here

i find the autofocus to be quite slow with teleconverter - if you're patient it will get there. with center point focus on stationary subjects it's still probably better than trying to manual focus. a focus light is probably a good idea. it's going to behave the on land as UW
