I have recently purchased the A80 and it is my first digital camera. My only previous camera was a 35mm SLR which I had been using for 24 years, on and off.
I have been trying out the A80, trying to see what characteristics it has and there was one thing I noticed very obviously.
When I take a night scene, I notice any exposure more than 1 or 2 sec will produce a flare with any red light. For longer exposures, any bright light (whatever the color) e.g. formed into words like the name atop a building, will become just one bright patch.
I have tried all kinds of correction, e.g. setting to different light source correction, making sure the f-no. is at the smallest f/8, having the camera on a sturdy tripod, using the 2-sec shutter delay to ensure no camera shake when the shutter opens, etc, but to no avail.
I have not tried using any filter, e.g. something that reduces the amount of red light, to correct it. This is because I am trying to learn about the nuances of using digital cameras before thinking of how to do something about the effect on the images. I am not too keen about using softwares to correct for the image AFTER its been captured. I like to capture a good image with the camera. (If the words came out as one bright patch, how do you get it to spell out what it was suppose to be anyway with digital post processing?)
Does anyone has the same problem? I do not know if this is a problem with the particular camera that I got (just my luck?), or it is a characteristic of the CCD used in the A80, or its lens design being not so good for red color, or that any digital camera, because of the limitation of the CCD, will have this problem. Is this some kind of spillover/crosstalk of the pixels when they become saturated?
Perhaps someone can share some experience with me.
