SharpStar uses ED glasses equivalent to the FPL53, same dispersion, same refraction index.
Let's clarify, I am quite certain that NO Chinese manufacturer uses the FPL53 glass by Ohara. In fact, if you check in their manuals or official websites, you cannot find "FPL53". You find this specification in the distributor websites so in case of a legal dispute, it will be hard to trace the origin.
SharpStar does not play this game and they just say the truth. The result from Martin are great and as you can see, there is no chromatic aberration.
