A 50mm M12 thread F1.2 lens has a doubler pressed onto it, effectively it making it a 100mm F2.4 with a fixed zoom of about 6 to 7 mag. The extra fine M12 lens allows super fine focus precision a lot easier than coarse thread cams manage.
The bullet cam is located in a tube that is carried by weaver rail scope mounts that currently have a dovetail adaptor captively fitted into them that can be removed - so will fit weaver or dovetail rails.
I should declare the camera has some tiny dead pixels that don't overly affect the image due to the neutral density gel filter over the screen that minimises screen glare into dark adjusted eyes at night.
The basic option has a 5" 800x480 resolution monitor for those with their own illuminator at £250.
A compact zoom VCSEL laser illuminator can be included at £300.
A further option is the inclusion of a DVR recorder at £30. Prices are 'collected'
