Pros:

-Speeeeeeeeeeeed
-f/2 systems are optically faster but have front mounted cameras so you can't use a filter wheel. This means that either you are throwing away 2/3 of the light because of a Bayer filter for OSC or waking up in the middle of the night to switch out filters for mono.


OR....

Buy another two such systems and stay in bed
