Hi
I want to follow-up on my lengthy report from last weekend with a more concise summary after further reflection. I would summarize my impression like this.
I wanted the 8X42 SF experience to be noticeably better than my EDG II or the Swarovision. I guess these are the 2 current "flat field" roofs that I like most. Based on only a brief first impression of 1 non-production SF sample, I cannot say I like the SF any better. There are a few adjustments still to be made that should make the final production SF feel tighter and more precise mechanically. I forgot to say that ergonomically the SF does feel great in my hands, nicely balanced and less dense than the EDG II or the SV. I like the longer open bridge design. When you first look through the SF, the super-wide field is surprising. They have obviously pushed the wideness of the field to a new level, while also adding a strong amount of field flattening. But the overall view--including the degree of flattening or the nature of the fall-off in image quality at the very outer edge of the field--seemed more "natural" in both the EDG and the SV. I think I was noticing a little bit of rolling ball in the SF, perhaps less so in the SV and not much at all in the EDG. The center field sharpness also seemed a tad better in the EDG II and SV, at least that was my gut reaction, but I'm not sure about this. So the good thing is I don't feel a strong desire to buy this expensive binocular, but I will reserve my final judgement until I can look through real production copies, and under better conditions, not blinding direct mid-day sun.

That's strange but interesting, if you are talking about the 8.5x42 SV EL?
Holger's chart shows (or at least projects) that the 8,5x SV EL should have considerably less pincushion than the 8x SF, which means that for rolling ballers, the 8.5x SV EL should show more RB.
However, Piergiovanni from biomania recently reported that out of the two sample 8.5x42 SV ELs he has, the newer one has more distortion than the earlier model, which confirms Holger's assertion that Swaro has been tweaking the distortion in subsequent production runs of the 8,5x and 10x and that the newer models including the 8x32 and 10x50 and 12x50 are less likely to show RB due to more pincushion, with the exception of 10x32 model, which could be due to its wider AFOV (a whopping 68*).
This could be the same reason why you see more RB in the 8x42 SF than the 8.5x SV EL even though the SF has more pincushion than the SV EL-- the SF has a larger AFOV and your sample 8.5x may be a newer production model?
