As much as it might frost some folks here, I noticed less difference in my 6-24X Weaver and the newer Tasco. This is based on side by side comparisons on deer antlers in the woods 131 yards away and eye charts 127 yards away. The only difference in my z5 and and 4200 is the tunnel vision is more pronounced in the 4200. Well, there is one more difference. The 4200 has note needed service, but the z5 did go back for a broken turret spring.
