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.
It is: 50mm = 5cm
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
50mm converts to 0.05m (multiply millimeters by 0.001)
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.
50mm drivers could be loudspeakers. (Tweeters)
168cm add 50mm = 218
10mm = 1cm 50mm = 5cm
A 50mm lens has a diopter of 20.
Between 50mm and 6cm, the later would have the greater length. That is because 50mm is only equal to 5cm.
