TV Mode?

I have a 50D and when I attempt to set the shutter speed to 1600 (for action shots) in TV Mode it switches to another shutter speed ie 1/60. Shouldn't it stay at 1600 regardless of light. I thought that was the idea behind TV.

I was using spot metering, ISO 400, outside, cloudy (AWB was set at cloudy).

Any ideas and/or suggestions would be appreciated.

Thanks in advance...

are you using the flash?

You have set Safety Shift. If you do, it will shift the time, if the time you select will render under- or overexposure.

Not utilizing flash, and I'm going to show my ignorance here and ask where and what is the "safety shift". I obviously didn't intentionally use it.

custom function menu is where the safety shift is located. OR in the regular menu area, i forget exactly, but one of the two places.

Which custom function it is depends upon the camera you have. But it allows you to get the right exposure in Av and Tv, even if you've selected an aperture or time that prevents that, according to the camera's exposure meter.
So in the case you mention here, your picture will be underexposed by ten times, which is a little more than three stops, since the camera wants to use a time ten times as long as the one you selected. That may be what you want, but there's at least a point in checking that you didn't do something wrong in a case like this one.

If you disable the safety shift, then instead the aperture figure will flash the lens' largest aperture if the camera considers the selected time is too short.

Thanks to everyone for your quick responses. I'm going to check it as soon as I get home.

I respond back to let you know what I find...

What sort of action are you shooting?

It sounds like your only recourse will be to max out your ISO...

A mixture of things, from combat (firearms) shooting to wildlife.

Ok - I don't have experience with those, sorry. For sports, I find 1/1000 to be ideal, though.

Thanks, I might be shooting some Football this fall, so I'll try that.

Hereare a number of racing images. It's possible to see the shutter speed used if you set the info level to expanded.
Different settings have been used for different images, so if there's any look you like, you can check that particular image.

SWEET! I Love Racing! Especially European cars. We don't have anything like that around here. Many thanks!

I did try to right click and check shutter speed, but no luck. No info available. I'm sure I'm doing something wrong.
