As stated not sure where to place this question. To me it is a Graphics question as when I am done with work I import it into Video Graphics programs - might be better placed in multimedia... but here is question.
I have a Sony Analog Hi8 HandyCam. I know I could have purchased a Digital8 or straight Digital Sony - but I owned a Video8 Sony for 10 years and had lots of older tapes and with a TV capture card I can bring the tapes on the computer easy. The question is about zoom.
The Video8 had a 12x optical. The new camera has a 20x optical and a 990x digital zoom. Over 40x it is useless. But I do find the 40x to be quite good in some instances. However, I get a small but noticeable shimmer when using 40x - similar to the effect of when looks out in a straight field of sight on a warm day with the naked eye and can see the horizon at end of view and sees "water". A heat effect.
Is this just a natural limitation of the camera? I can use an unsharp filter and eliminate most of it. Straight optical produces no such effect. So I was wondering if I obtained a true optical lens to increase optical by 2x or even 3x if I would still have the same problem. Any thoughts?
