The 100-400mm is a great, workhorse lens.

Thanks Dave, not looking for AF just looking for it to work. Here's the info I just posted on POTN:

It doesn't function at all when I install a TC on it.

- What I've done to test:
> Tried it with 2 TC's
-> Kenko 1.5x TC (not a typo, I have the older 1.5x)
-> Canon 2.0x TC III (I thought it was the old Kenko so I rented the Canon and same thing)
-> I've successfully used both of the TC's with my 400D/Rebel XTi (the 00 shows for aperture when the TC is mounted without a lens, but then shows correct aperture when a lens is mounted) I am able to shoot with the Rebel and either TC!

- Symptoms
> Cannot depress shutter at all - cannot take a shot
> Cannot change ANY settings such as ISO, aperture, shutter speed, etc.
> Aperture displays 00
> Does this with or without a lens mounted on the TC with both TC's
> Basically it looks like it thinks there is no lens on the TC even though there is

The only thing I haven't done is update to the April 2013 firmware release. It was some date/time fix so I'm not sure it'll make a difference but will try later tonight.

Questions --

Anyone else experience this or something similar?

If so, is this some sort of a fault where I need to send camera to Canon or was it fixed with firmware?

Am I missing something really, really dumb here?
