Message: <blockquote data-quote="crinklystarfish" data-source="post: 3532082" data-attributes="member: 122209">I just tried this with my 10x version looking through the right barrel only. I looked at something akin to a cotton reel, indoors, at about 4 metres. The object was on a windowsill, so strongly backlit.The image presented is - to my eye - most like the middle row, the Nikon SE. I see a slight compression of the right side of the circular object used, which also slips out of focus as it is 'moved' to the 3 O'clock position. The object can, however, be brought back into pin-sharp focus with a shift of the diopter adjustment.I also looked at a vertical window frame and could see no obvious deflection - the edge of the frame seemed - to me - to remain vertical.I agree regarding the colour fringing observation. This was green-ish to one side / mauve-ish to the other of the circular object, but was only evident when viewing the object at the extreme 3 O'clock position, and could not be 'focussed out': it steadfastly remained no matter the level of re-focussing.I use rather than study optics and present these observations in purely layman terms. The technicalities of astigmatism / rectilinear distortion / angular magnification distortion are not concepts I would presume to wield freely.Whatever Nikon have done I find the result very pleasing and - in actual use in the field - my 10x consistently refuses to throw up any distractions that have been a source of huge disappointment for me whilst using 'Alphas'. The control of veiling glare when looking into dark 'walls' of vegetation under otherwise open skies is a particular winner for me. This phenomenon ruins my enjoyment of so many bins.Usual caveat - I fully accept different people will have different perception.</blockquote>
