Ok, this is a serious question I have here. I use a dig cam, kodak dx 6440 Supposed to be having A 4.0 megapixels 4X optical zoom 3.8X digital zoom It is also supposed to have this B SCHNEIDER-KREUZNACH VARIOGON 4X Optical Zoom Lens and C Powerful 4X optical zoom (33-132 mm equivalent) from the leader in lens optics technology and D 3.8X Advanced Digital Zoom. Now, the question. Can someone explain to me the ABCD as i put above?? 2. What is the diffrence between optical zoom and digital zoom? The cam is supposed to be going 15x zoom with both features available and it does too but my experience with zooming has been bitter. The pictures are not sharp and there is heavy pixalation. 3. Is it because I did not use a stand that I get pix and blurr or s it that it is inherent in zoom to get the blurr or am I being fooled with the promises. I shall upload a zoomed pic for your reference as to what I am complaining about.
