Tree bark is generally available (where trees grow) and has very subtle shadings and textures.
It is an admirable subject for comparison of optics, as are the lichens which grow thereon.
It also stays in place.
Perfect for setting diopter.Wish I had thought of this earlier. I use tree bark, (and moss and lichens) on the oaks and pines in my yard to get the most precise diopter adjustment and it works for me better than anything else in this regard. Never thought to do that to specifically compare the different color shades/renditions of various bins but it's a good idea.
In terms of equipment I see in casual use, mostly cameras and a few medium sized lower priced roofs. When at local birding hot spots my ADD has me focused exclusively on the birds.
Déjà vuTo update on one of the unknowns, I now find it is an Opticron Verano...I have one of these and they are nice bins for sure....
Zeiss---2 (Terra and Conquest)
Nikon---1 (Monarch 5)
Meopta---1 (Meostar, my pair today)
Later on I went up to a pond to view some birds and I saw these:
Swarovski---2 (NL and ?)
Just a thought about the bird in Acadia NP, but it could have been for the Stellar’s Sea Eagle that seemed to be very lost during 2021 & 2022.We hike all over and I can count exactly two times I've seen anyone glassing. One was at Acadia NP in fall 2021 on Cadillac Mountain, we hiked the whole mountain and on the out on the down side there was a larger group of birders with a lot of nice stuff. Lots of spotters on tripods, high mag binos on tripods, lots of Swaro logos. We overheard them saying there was some rare hawk there at the time but didn't know what and we weren't really into it heavily at the time. We also had 3 dogs with us so getting really close to the group with expensive glass on tripods wasn't feasible. Then more recently some lady hiker ended up close enough to us on Blood Mountain that I could see she was glassing but couldn't tell what, maybe Zeiss or Leica judging by the aesthetics.
We see a good amount of people with cameras though. Most are not professional cameras though nor do they have telephoto lenses. I'd say 90% of the people we come across are just people out on a hike with no interest in much of anything else. They'll see us observing wild life and keep on going with no interest in trying to see or find out what we're stopped looking at.
I am just a stones throw away from there when back at home . I was at the show last may and bought 2 pairs of NL Pure's and a 115MM Spotting Scope right inside those white tents setup at the entrance to the Marsh. I plan on going back in May again when we leave Sri lanka ..If any of you can, you need to make the effort to go to "The Biggest Week in American Birding" at Magee Marsh on the north border of Ohio. Seriously. There will be probably hundreds of birders there and yes the birding is that good. Really it's unbelievable the number of species one can see in only a few days. There are birders there from all over the world and from all walks of life. I won't say Swarovski was the number one binocular there but it was close. It was certainly the most seen premium binocular. SVs were everywhere. You will see folks with every brand you can think of. Some buy binoculars just for this trip. Some have never even used a binocular before. Vortex was probably #2 follow closely by Nikon. Zeiss were very common with FLs and Conquest HDs and some SFs.
