i bought a 2.5-16 as well,and must admit it seems alot clearer and crisper than my older leupold vari-x III 6.5-20x40
I had a similar observation.
I tried these three out on a fake rifle stock, and didn't like any of them:
a) Bushnell 3200 3-9x40
b) Bushnell 3200 5-15
c) Bushnell 4200 2.5-10x40
I found it hard to see a round paper target that was 20' away. It was in focus and there, but just hard to see. When I turned the magnification up the lit area of the image got very small. Perhaps I had my head in the wrong place.
Then I tried
d) Bushnell 6500 2.5-16x42 with 30mm tube.
MUCH BETTER. Target was very easy to see. Big and bright and clear at all magnifications.
A few days later I looked at
- Leupold VXIII 3.5-10x40mm
- Leupold VXIII 4.5-14x40mm
- Bushnell 4200 2.5-10x40mm (as a control between two stores)
I didn't see anything that really impressed me.
The Leupolds seemed to have a brown tint.
The Leupold 4.5-14x40 I looked at, had a very thin reticle that disappeared in the vertical striped wall I was looking at.
The Leupolds I found hard to focus when shifting magnification and far/near targets.
As for brightness and visual clarity, there wasn't a stricking difference between the three of them.
I was expecting to be astounded by the Leupolds -- given the way people rave about them.
So I bought a Bushnell 6500 2.5-16x40 mildot
