We have had the ability for many years to produce and represent audio and visual data in the digital domain at qualities which far surpass the abilities of analog systems. That is, it is the
analog systems which fail to reproduce these digital signals
accurately. We could process your images and audio at 64 bits per channel easily (and do in some cases), but there is no monitor capable of reproducing that quality.
Your lens analogy fails because you are comparing a lens to pixels. It's an apples to oranges comparison. You
do know that digital cameras have lenses, right? Then your analogy ought to compare the two storage formats: Film vs a digital image. You wrote: "
Digital pictures will have a limit of how much you can zoom in…" -- The same applies to film.
You said "…
when we are talking about reproducing information as detailed and as true to the source as possible analog systems are still the best.". By what measure? Digital audio systems used in recording and mastering facilities have lower noise, greater dynamic range, and wider/flatter frequency response than the 2" machines. That digital recording format is capturing the source signal with greater accuracy.
As I wrote earlier: So you prefer analog. Use it. But don't pass this information along as truth. Pretty pleeeeaasee
