OT: Inexpensive digital microscope

[Pimpom]

I'm thinking of ordering a cheap digital microscope like the one
in the link below. I don't expect to get the image quality of a
$1000 optiocal lab microscope but the sample images look quite
acceptable to me. OTOH, judging from the width in pixels of
elements in the images - like individual fibres or the ant - I
believe they must have been captured at magnification levels well
below the maximum possible. I'm wondering how much the image
quality degrades at higher magnifications.

Even if the zooming is optical, lens quality must be a critical
factor for useful resolution at high magnification levels. For
example, does a 500X image look like a fuzzy enlargement of a
200X image with no increase in detail, as in a digitally zoomed
camera photo? Input from those who have used these devices will
be much appreciated.

I have one very similar badged "Veho" and suposedly does X200
magnification. It does not work in Linux which for me is a big
disadvantage. The major issue is that as the magnification increases
so does the closeness to the object of interest. Its only 1Mpx and
while the image is aceptable for 600 X 800, I get far better results
from using my digital camera and macro mode.

Thanks, and sorry about the long delay in response from my side.
I'm a photography enthusiast and I too use my camera to get
enlarged images of objects, but that method is not always
convenient. I went ahead and ordered the piece. (It's an X500
model for $17.94 but the URL I gave now links to an X800 model
for $29.99). I chose the free shipping option by China Post and
judging from the experience of some friends, it will take a month
or more to get here. I saw no point in spending an additional $35
just to get it a bit sooner.

No sweat
Lets see how it works when you get it. For me, I'll just carry on
using the camera !
