[QUOTE="bruce_ventura, post: 874345, member: 34084"] No, the FFP reticle is not etched on the objective lens. It is located just in front of the erector. I believe that FFP scopes cost more because the reticle has smaller features and costs more to manufacture. SFP reticles are located between the erector and the eyepiece. The erector magnifies the image at the first focal plane, inverts it, and produces a larger image at the second focal plane. The SFP reticle is therefore larger than the FFP reticle and can be made inexpensively. The smaller features on the FFP reticle must be made using a more expensive photolithography process. [/QUOTE]
