Wide flat field and edge sharpness an illusion? (1 Viewer)

[Ignatius]

@Maljunulo @Alexis Powell I am continually surprised at how different our eyes/brains are and thus our individual viewing experiences.

Interesting that your experience is the exact opposite of mine. In general, I don't get rolling ball from Nikon bins w/flat field, but the 10x42 LX is so strong, I almost feel the need to duck to avoid being hit by objects that come flying toward me as they move from edge to center of the view during panning! The effect in the Swarovski looks to me much more modest and the rolling is restricted abstractly to the view in the distance.

Fascinating.

That’s why I keep banging the tired old drum “look through them”.

I fact, I have no clear recollection of rolling ball in the Nikon. This is not to say it wasn’t there, just that I don’t remember it.

I found it to be overwhelming in the EL-SV.

I thought the rolling ball was much worse in my 10X42 EL SV than the 10X42 Venturer LX, which it replaced.

It required a constant effort to overlook RB in the Swarovski glass.

And The 10x42 SV actually has a small amount of pincussion distortion, which can be verified by observing a grid pattern through an objective.
This then appears as barrel distortion.
