FZ28 'conversion' setting ? (1 Viewer)

Hi,

does anyone actually know what difference it makes to the camera/photograph when I set my FZ28 'conversion' option to 'on' when I fit a teleconverter lens ? The manual is a bit vague ....

Does it matter if I select it or not when using the teleconverter ?

Thanks very much.
 
The one effect I know of is that the setting limits how far you can zoom out, to avoid vignetting.

One additional use that may or may not be true, and which really should only apply if you used the original converter: when making the jpg image from the raw data, the camera seems to use a software correction for chromatic aberrations. (I am not sure where I read that). This correction is dependent on the zoom factor, and could potentially also depend on the presence of the converter.

Hi Dave, I leave the conversion setting off even when I use the converter, and have no problems. The only issue I know of is that with the conversion setting off, you can zoom out farther so that you will eventually get vignetting (as Niels suggested). But I find that the conversion setting is too restrictive -- it limits the zoom range beyond what is necessary to eliminate vignetting.

Best,
Jim
