As far as quality and durability vortex has Leupold and Nikon beat. Optics_----- That's all in how you see things .I have looked thru the vortex viper HS model VHS-4302 44mm,Leupold varx-3 2.5x10 50mm and Nikon Monarch. an apple to apple comparison. Vortex won in clarity but lacked slightly to the Leupold in low light clarity followed by Nikon. Very slight differences between all 3. Vortex around 380.00 us. Leupold comes in at 549.00 us, and Nikon at 479.00. for the money its Vortex, leupold then Nikon.

Canon makes the best 50mm camera lens, known as the EF 50mm f/1.8mk2, 50mm f/1.4 USM and 50mm f/1.2L lenses
50mm from 0.14mm = -49.86mm
I would think so, yes. A 4 or 4.5 power scope is a great magnification for beating the brush, and if it's anything like up here, shots from as close as you want to 100 meters will be a cinch. With a 50mm objective lens, you have great light gathering capacity and a good field of view, and you can dial up the power for longer shots.
