Q
Will this fit my Sigma f2.8 24-70mm lens with 82mm threads?
A
Dear Customer, it could fit your Sigma f2.8 24-70mm lens with 82mm threads. 
Q
Can I see objects in dim light?
A
For this binocular 20x50, as the diameter of the objective lens is 50mm, for binoculars, the larger the diameter of the objective lens, the more light it collects and therefore can be seen more clearly in dimmer places. Please note, however, that dim/low light ≠ night vision and cannot be used in total darkness. 
Q
Will the nikkor 50mm 1.4D work with this?
A
Yes, the Nikkor 50mm 1.4d is an f mount lens so it should adapt just fine. 
Q
Hello, i have a nikon 50mm af-s 1.1.8g lens. is this compatable?
A
I don't have that lens with me. On the inside of its lenscap and on the ID on the lens, there should be the size of filter needed. If it requires a 58 then you are fine. There are also adapters to go up or down. 
Q
will this fit on a 50mm prime lens canon?
A
No
