Gents, maybe you can explain how the Swaro ZOOM works.

Would it be wrong to say there: 1.7-10x42 is equivalent to 14 power. The 2-12x50 = 16x???

Just trying to get me head around their concept. Thanks again :)



PS-which zoom power do Zeiss Victory?

6x Zoom, Multiply the low end in these cases 1.7or 2 X 6 gives the upper end of 10 or 12.

They work very well.  Have/use both the z6 and a 2.5x10 and the 6x24 daivari and the z6 is unmatched  especially in the lower end of the scope's range by any other scope made. Diavari have a 4x erector or 2.5x4=10. Also be aware that these numbers are just approx. Rarely does a scope have the exact numbers they advertise if you were to measure the actual power against the ring indicator. Another thing to keep in mind is that zooms, regardless of zoom range, really have only a low, med. and high magnification. As an example it is impossible to dial in say something like 6.68 power. The variable ring has no "click" stops to make it usable in this regard.

Thanks you for your answers.


This suggests, there is no real difference on the HIGHER power, but benefits on the lower. Is this correct?

Yup the FOV at 1.7 on the Z6 is 75 ft while the Zeiss Victory at 2.5 is 43.5.  Huge difference, which comes in nice with close quick shots

If your looking for more on the top end 2.5x get you to 15x, 3x to 18x, these are quite interesting  for hunting purposes. Who wouldn't like a great top end to go small low end. Wink

Most 30mm scopes have a 4X zoom factor, i.e. the highest magnification power is four times the lowest magnification.  2.5-10X and 3-12X are a common examples.

Swarovski simply widened the typical 4X zoom ratio to 6X zoom in the Z6 line to provide more versatility.  It functions the same as any other variable scope; the erector lens assembly just has greater range of movement than 4:1 zoom ratio scopes.
 
For years, the typical 1" tube scope has had 3:1 zoom ratio (ex: 3-9X, 4-12X, etc.).  Now, they are moving toward 4:1 ratios.  Swarovski offers a 5:1 zoom in their Z5 series 1" scopes.  It's easier to make a high zoom ratio erector assembly work with larger tube diameters because the larger tubes provide more room for larger zoom lenses.
 
Bushnell has 6.5:1 zoom ratio scopes in their Elite 6500 line.  March even has 10:1 zoom rato scopes.  You will likely see the high zoom ratio trend continue with more manufacturers.  This means that fewer scope models will cover a wider range of shooting applications.

Or, another way to look at it is if you compare it with a typical 4:1 scope of the same low end magnification and field of view, you have much greater magnification available on the high end should you need it.
 
I have a 1.7-10X42 Z6.  I like the fact I have much greater field of view at 1.7X than a typical 2.5-10X42 scope offers without sacrificing the 10X on the top end.  But someone else might like it because it has much greater high end magnification compared to a typical 1.5-6X scope with similar low end field of view.

Thanks, I think I understand how it works, now.

1.7-10 & 2-12 Z6's do not give any more zoom on the higher power. So their 10 is 10, 12 is 12. It's just on the lowest power it ZOOMS UP. Confusing somewhat.

Thanks again gents :)
