Shutter Speed Weirdness...

So this was weird:

I was shooting a band last night. ISO was at 1600, and I was shooting in Manual mode.

About halfway through the shoot, regardless of which way I turned the wheel to select a shutter speed, the speed went up. Left or right, it didn't matter. The shutter speed only increased.

I removed the batteries and reinstalled them. I removed the grip and reinstalled it. Neither worked. I removed the grip, replaced the batteries with fresh ones, and that seemed to fix the problem.

The weird thing, though, is that the original batteries had a lot of life left in them. When I put them on the charger, the light on the charger was green (charged) in a matter of minutes.

I was just wondering if anyone else has experienced this...

I had that happen once. I don't recall which body it was though. The really odd thing was it didn't even matter which dial I turned...

None of the controls actually change anything in the camera. All they do is provide a stimulus so that the processor can change the settings with the exception of zoom, focus, and maybe a few others. Anyway, software can at times get confused which could cause many funny things to happen. Removing the batteries and waiting a few minutes causes the processor to reset.

That was my thought, too. Given that the replacement of the batteries fixed it, I was also thinking that maybe the camera just doesn't play nice with batteries that have a lower than optimal charge...

Ctrl-Alt-Del...

Funny...don't remember having these types of issues on the Pentax K1000

next time, turn off the grip. sometimes the grip acts weird on any camera (X0d and XX0d cameras alike) and you can only change the top wheel to the right (left acts like right)

.... or on my Nikon F's.

Pulling only the main battery (or batteries if using a "grip") will not cause the processer to do a "three-fingered-salute" type of reset. You have to (at least on the 20D and its sisters) also pull out the disc-shaped memory battery as well.

After leaving both the main battery(ies) and the disc-shaped battery out for a couple of minutes, the processor will reset and all user-configurable settings will return to factory-original when putting the batteries back into the camera and turning it on.

The only weird thing my 20D does is freezing up (albeit very rare) that neither buttons would work anymore. Luckily, turning it off and then back on solves the problem.

But isn't the 20D a notoriously problematic camera? Too many firmware patches were done for it, that probably the code is a mess right now.

Well, if that's true, then this isn't the issue with my 20D. I only removed the BP-511's...

I have had one minor hangup with my 20D in all the time I have used it. Cycling power resolved that issue (which I can't even remember the details of).

I'd say that overall the 20D is a pretty solid camera, especially if it has the latest firmware loaded properly into it.
