2" UltraWide Prime Focus Adapter for Sony E Mount
                       (Fits NEX/A7/A9/QX/VG Series)


T-Minus 2" UltraWide Adapter for Sony "E" Mount
                    (Pictured with Optional Filter)



The T-Minus adapter goes directly from Bayonet mount to 2" barrel.


This increases the clear aperture from 1.5" to 1.85" compared to a T-Ring. 
                                 There is zero shading of the CCD sensor.

 T-Minus takes it's name from that fact that it is shorter than the "T" standard. 

T-Minus is over an inch shorter than a T-Ring/T-Mount Combo! Great for Reflector Owners!

T-Minus™ adapters provide distinct advantages over a T-Ring solution...

T-Minus adapters are a part of our larger "True-2" UltraWide Adapter line, as such they offer a full 10mm more clear aperture than a T-Ring setup. 

T-Minus takes it's name from that fact that it is shorter than the "T" standard. T-Minus adapters are over an inch shorter than T-Ring solutions, for reflector owners this means you can likely reach true prime focus for the first time (without any telescope modifications or telenegative lenses). 

T-Minus adapters are CNC machined from a single piece of aluminum making them lighter, stronger and with zero chance of separation due to T-Ring failure. In addition they are fully baffled to reduce reflections and threaded to accept standard 2" (48mm) eyepiece filters.
