I wonder if the new 76mm will replace the DC and DS.
Was wondering the same about the FS60. I hope they keep the CB as the CP is just wider body but can still use the Q module though require different shell clamp than the 60CB and 76DCU
No, the TOA series use two FPL53 fluorocrown elements either side of a BSL7 centre element while the the FS and FC series use lab grown CaF2 fluorite. TSA optics are the reverse of TOA, ie, BSL7-FPL53-BSL7
