In my ZS71 I get (theoretically) 6.3 degrees TFOV with my widest 2" eyepiece
True, but you're only talking a magnification of 10x (assuming a 41mm Panoptic), and not great contrast.

As noted above, I'm really focusing on the trade-off between aperture, focal length (for good TFOV) and CA. The ZS71 ticks the boxes well on the latter two criteria, but only has the same aperture as my binoculars. I'm looking for something a bit more in between. I'm thinking more and more that the 102x510 is the right compromise for me, but I'm not yet convinced! It's a really tough choice between this and the 120x600...

Someone, pleeeaaasseee, give me something definitive to decide on!
