With my Gl2 I believe the LUX is aroung 4 1/2. In low light I set to aperature priority to let the most amount of light in.(Does not improve quality but makes me feel good.) When I set to aperature priority and set it at the lowest point(think it’s 1.6 can’t remember) I still can’t blur the background. Everything is in focus. I know with cameras the lower the aperature the shallower the depth of field. So can someone tell me why I can’t blur the background? I can shoot my wife’s camera with a lens of 5.6 I can blur the background out. If I use her 2.8 lens I can have 2 people standing next to each other and one person is out of focus.

You don’t say what focal length the lens is at or what distance you are focused at- both of these have influence on depth of field, in addition to the aperture.

You may be a f1.6, but if you are at extreme wide angle, focused at infinity, it almost won’t matter. Get close to your subject, focus close (obviously) and aperture will have a much more significant impact on depth of field.

One of the things I find lacking on camcorders is a depth of field scale- but I’m new to video (I’m an old still photog) so maybe I just haven’t purchased a camera with that engraved on the lens yet!! 😀

All of my still camera lenses have a depth of field scale engraved on the lens along with focus marks, etc. But with 35mm still photography, you couldn’t preview depth of field (except on very expensive cameras) before taking the picture (since you looked through the viewfinder at maximum aperture)- you didn’t see the effect until the film was developed. So the scale needed to be on the lens to assist. Electronic video and still cameras have a huge advantage in that regard.
