Hello Larry I get very good exposure when using my in camera exposure meter, in difficult exposure settings I do have to use exposure compensation. when using external flash the in camera meter is of no use.

"when using external flash the in camera meter is of no use." I think you have that backwards, Bernard: the in-camera meter measures the light output from the (external) flash and shuts it off when there's been enough.

You question regarding built-in meters is awfully vague. What do you think the function of a built-in meter is? This is a devise that measures the light intensity, intercepted directly from behind the lens i.e. the image forming rays from the lens. Measuring at this location has advantages. Scene brightness is taken into account along with any dimming effects caused by filters, extension tubes, or focal length changes etc. Once the data has been gleaned, chip logic (software) directs the settings of aperture, shutter speed, and ISO. The idea is to obtain correct exposure. Likely, the probability of correct exposure from this lash-up is higher than any other method including using a hand-held meter. There are always exceptions. Camera makers have invested years of experience into this hardware and software. Nowadays it extends beyond ambient light reading into the realm of controlling the intensity of the built-in flash. This is truly remarkable stuff. Once upon a time we had to take multiple reading with a hand-held and using (maybe) our best judgment and experience interpret this data and then manually set our camera, hoping for best results. Today’s logic has multiple modes, spot reading or average or calculated weighted average etc. As time goes by, maybe, cameras be able to read your minds eye and set exposure and focal lenth accordingly (who knows?). My advice is, don’t negate these marvelous advances. Alan Marcus (marginal technical gobbledygook)

Yes you can, but as some people have alluded to, you'll have to learn to recognize when situations will cause using the camera's meter alone will result in a reading that won't give you a good exposure. And you'll learn what kind of adjustments you'll need to do to get a better reading. But all relatively easy to learn given a little time and application.
