Just received the 3-12, because I felt the 5-18 had too tight of a FOV. I found out that the 3-12 is 10 oz lighter from another forum. I was suprised when I opened the 3-12 the objective lens is barely 1" in diameter. The 5-18 is slightly over 2.25" in diameter. The 3-12 has approx .80 square inches to gather light. The 5-18 has approx 4square inches of light gathering ability. I guess I'll be going out tonight to see how much difference there is in them. On the 3-12 focus ring is less than 1/2 a turn from near to far. The 5-18 focus ring turns almost 3 full turns from near to far. I did notice on the 5-18 that it was only necessary to turn less than 1/2 turn to go from 30 yds to approx 150 yds.
I'm hoping there isn't much difference in the brightness of the 3-12 vs 5-18....
