Whe first researching prismatics scopes it seemed the perfect design for PCP hunting: a WIDE field of view at close ranges for quick target acquisition — but without the disadvantages that usually come with it, namely a low magnification.
Some guys reported their experiences with the prismatic scopes over on GTA.
Cableaddict (sceeen name) used a 10x or 14x, I think, and reported a
wonderfully wide field of view —
and an
abysmal depth of field (parallax and sharpness range). Meaning that getting quarry in focus required really fine tedious adjustments — and if the quarry moved just a little closer or farther away — focus AGAIN! This kind of fiddeling with the parallax
wasted the time saved with a quick target acquisition helped by the wide field of view of the prismatic.
Well, in a hurry I jumped off the bandwagon that I had been pushing this far....!

PS: And the bigger the objective lens, the smaller the parallax and sharpness range (depth of field).
Nothing is free in the optics universe, it all has its price.....
