5x zoom vs 3x zoom
So my new Conquest HD5 5-25 has 5x zoom factor, and my conquest 6.5-20 has 3x zoom. I cant find anything in Zeiss website that helps me understand the difference. they have this in their FAQ:
What is the difference in magnification ranges between the CONQUEST MC riflescopes and the new CONQUEST HD5 riflescopes?
The new CONQUEST HD5 riflescopes feature a magnification that is a 5x zoom factor, i.e. 2-10x in the 2-10x42 CONQUEST HD 5 versus a 3x zoom in the older CONQUEST MC riflescopes; for example the CONQUEST MC 3-9x40.
I know technically there is a difference. You take the highest magnification and divide it by the lowest and it gives u the zoom factor. i guess I'm just confused about what difference am I supposed to see when I compare the 2 in real life?? When I put both of my scopes on 10x zoom, for example, and point at the same target, I dont see any difference between the 2. Am I even supposed to see any difference?? Or does it simply mean that I can magnify the image 5 times from the lowest zoom to the highest and thats it?? When Zeiss says "High resolution 5x zoom for ultimate versatility" in their brochure, is this just a typical marketing BS or the resolution for 5x zoom is actually better than the 3x?
