What's the difference in a zoom lens and a macro lens for a camera? - zoom in viginas
I need a telephoto lens on my Pentax camera (K-mount) to take pictures of animals, sewing, etc., which are far away. What is the difference from 200 to 200 meters zoom macro? Usually it is to enlarge the same as that of a wide angle?

Zoom In Viginas What's The Difference In A Zoom Lens And A Macro Lens For A Camera?

Zoom focal length adjustable.
Macro refers to the ability to focus very closely.
The objective is to either, or both.
A macro lens is like the other (zoom or fixed focal length) with additional capacity. It allows you to get close enough to a focus crisp, 1:1. An example would be a close-up of a flower, butterfly, or architectural details.
Not to be confused with a zoom lens that collects the most distant objects.
Here are some examples from Flickr as a "macro-and Pentax."

Regarding your last question is a "Zoom" usually includes a series of short-to medium-telephoto. An example is a 70-200mm.
There is a wide angle to telephoto, starting with 18 mm or less in the larger end, and ends at 135mm to 200mm telephoto.
Here is a list of current digital Pentax lenses.

I hope this is helpful.
Imagine if in this way a 200 mm zoom lens is like a telescope and a macro lens is like a microscope.
A macro is given to extreme close-ups. For example, flowers, insects and so on. A telephoto lens is used to things appear far closer.
Most macro lenses can focus at infinity, as a normal lens, as it can be used.
