Yes, I'm sure this is a beautiful scope. I can really tell the difference in light gathering capabilities of my Premier 3-15x's vs my Premier 5-25x's... both of the 56mm 5-25x 's outperform both of the 50mm 3-15x's in low light situations, so much so that I have a strong preference for the 5-25x, even at the same mag range (10-15x for both).
Great example: I have a 650yd lane on my farm - FP in the woods on ridge, thru pastures and into TRP in the woods near river. It gets very misty down there and at 1930 hours or so, last light is fading fast. Target is a white 8" popper which we call "The Ghost"... because it looks like one in the mist. Anyway, it is so much easier to see and successfully engage with the 56mm scopes than the 50mm's.
For precision rifles that are used field conditions, I will not purchase another scope that doesn't have a 56mm objective lens.
