I had a brief opportunity to try out the 60 mm model in comparison to my MM3 60 mm. I also received the newer version of the 23x (on the 60 mm) wide angle HDF eyepiece. I mounted the new eyepiece on the MM4 and compared it against the older 23x wide angle eyepiece on the MM3 60 mm.Just a couple of observations.....I didn't immediately note any difference in increased apparent sharpness. Both spotting scope combination were very sharp to my eyes. What I did note in the new MM4 combo was an increase in contrast and color saturation. Now whether this is just the new scope or the combination of new scope body and new eyepiece I cannot say but the difference is there. The MM3 was already above average in these areas but the change was still immediately noticeable.One other issue I noticed was the change in antireflection coloring on the objectives. Gone are the red/purple reflections. Replaced with more green/purple.More to follow as I have more time to experiment.Still no MM4 80 mm :-( . One can always dream. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /></blockquote>
