I have the 6.5, 9, 12.5 and 17.5mm Morphs. They are far and away the best EPs I've ever bought, so like several others, I've stopped lusting after more expensive alternatives. The various TV ranges disqualify themselves for me because of either price, FOV or eye relief problems.
I find the Morphs completely 'transparent' 😆 in the sense that they don't hinder my eye in any way and have no discernable aberrations. I also own a couple of Pentax XWs (5 and 14mm) and while they're very good, the Morphs have an x factor I can't explain.
I also have the Celestron Ultima Edge 30mm, which is just as good.
So I've gone from an inveterate EP purchaser to zero buys of late.
