Dear All,
I wanted to post an update.
The FL trip went well with both the Maven 9x45 B2 and the 8x42 MHG. The bins were each on a comfortable-but-definitely-overpriced-RY-harness. I was able to find a relatively better eye-placement with my MHG copy to minimize its top-left shadow problem (mentioned here:
https://www.birdforum.net/showthread.php?t=372918, thanks to Caesar’s post), but it is still present.
Our trip included the following areas, and species: {Orlando: Merritt, Viera // Tampa: Fort De Soto // Ft. Myers: Ding Darling, Corkscrew Swamps // Florida City: Everglades, Wakodahatchee, Greencay}. Being newbies, as first time lifers, we added {common, purple gallinules, gray headed swamphens}, {white Ibis, roseate spoonbills}, limpkins, {tricolored, little blue, green} herons, {wood storks, sandhill cranes}, least bitterns, { white-winged doves, white-crowned pigeons}, brown pelicans, anhingas,{blue winged teals, black bellied whistling, mottled, redhead} ducks, {willet, black bellied plover, killdeer, rudy turnstone, spotted sandpiper, royal tern, short billed dowitcher}, swallow tailed kite, loggerhead shrike, painted buntings, {black and white, yellow throated blue, palm} warblers, and {blue gray gnatcatcher, blue headed vireos}. Without binoculars, there was no way we could have differentiated the warblers, and identified the beautiful swallow tailed kite / white-crowned pigeons / willets. The willets were in a protected nesting area far away; the kites were only noticed with a random binocular scan of the skies from the parking lot of the Flamingo visitor center. The ancient looking Wood storks were my favorite. Gators, crocs, manatees, and anhingas were the primary attractions for most visitors it seemed like. Kayaking with the crocodiles a few feet away as the manatees glid below us, gators grabbing an almost-mature brown pelican/taking their time chewing a Burmese python from the tail end over a week, the conservation stories behind the Cypress swamps/Glades/Wood Storks were all great to do/see/know-about. A great experience that we were fortunate to have, indeed.
Relative to the MHG, B2 was verry snappy, sharrrper, had greater control of glare, ghosting, and heavy. I want to emphasize that I loved its quick focus in the warm FL weather. On a cold winter day in the North East however, its focus wheel became quite stiff to be of any comfortable use.
Relatively speaking, MHG was very light, wider FoVd, quite soft / un-sharp, very slow focus with at least a couple of back and forths especially when the light wasn’t bright. This last aspect of the MHG, I REALLY REALLY dislike. While the focus wheel tension stayed extremely comfortable in cold / hot days, the hinge tension did become less stiff in hot FL days. I preferred the relatively higher color contrast feeling of the MHG but this could be a side effect of poorer transmission of the MHG relative to the B2.
In both binocular models, I felt that CA-wise, up to proper eye placements, on-axis, there isn’t any fringing worth talking about. CA started at about 45-55% of the FoV from the center, progressively became more apparent in the edges. BUT, rather surprisingly to me, with consistent use in FL, I wasn’t bothered that much by off axis CA at all! I will check how these observations change on snowy, cloudy winter days up here in the North East. All that said, relatively speaking, with the MHG, I was able to consistently find better eye placements quickly and easily. I experienced more CA-free on-axis views; when present, it was easily repairable with repositioning. May be its the weight of the B2 that interfered here, and/or my past experience with the MHG, or something else.
Shakes wise, I felt that I sometimes got less-shaky views on the B2, sometimes with the MHG. I haven’t been able to conclude which one I prefer the most.
The heaviness of the B2, although dampened with a harness while carrying around, certainly limited extended hand-held viewing times. But if one only cares about IDing, and moving on to the next bird in the field, I am inclined to say he/she might not find its weight limiting.
I vastly preferred scanning the swampy Everglades, FL’s shores and the blue/cloudy skies with the MHG , as we were covering several miles walking. Its higher depth of field does interfere hugely when it comes to achieving the perfect focus, but it proved itself to be handy several times in the following way: we would be watching a sandhill crane far away, the wide FoV would catch a small very-fast moving flock flying rather close to us, we would have only turned the bins to follow the flock, wouldn’t have even touched the focus wheel yet, yet would have already got a very good sense of the flock’s identity. In a place like FL, this happened several times, and I was glad everytime I held the MHG. MHG is a great birding binocular in that it offers comfortable views in the woodlands and wide open shores, effectively following quickly moving subjects over near and far distances, retaining natural colors well, and I didn’t notice it lying around just like how a tool should be.
I finally realize why experienced birders like PBJosh/Chuck/David and others recommend the MHG as an 8x for the budget, even though it might also be the most disappointing in certain attributes, especially sharpness/resolution. By resolving the neck bands & eye color, the (9x) B2 was far more effective in telling us newbies that what we saw was a killdeer & not a semi-palmated plover. Getting closer to the bird, which might not be feasible all the time, MHG pointed us in the right direction. David/Steve/Chuck did offer the right advice for my original question: B2 is a significant step up. And finally, just like Andy predicted, I am not as worried as I was on losing that Toric anymore. I still would like one more go at it though.
In summary, this is what I am inclined to conclude based on my experience: B2 is a significantly better binocular. MHG is a better birding tool. There is no way, I would pay ~$1K for the MHG. $700-$750, gladly!
I will close here, and I will update the post if I am swayed by the future Genesis / Meostar at some point in the future.
For now, thank you everyone! :t:
