My thoughts on the Bushnell Legend 8x42mm Roof Prism Binoculars
EDITED: First Impressions and Adjustment Sections.
I want to state that I am an eyeglass wearer. I have worn eyeglasses since I was six years old. I am very near-sighted. I can see clearly without glasses for about 12" and after that I can't see clearly, so my prescription is fairly strong. Also due to age, I need trifocals, so I use Progressive lenses. This means I have to get my binoculars up to the "sweet spot" to see through them, so it probably biases my thoughts on binoculars.
I also find that I am bothered by "coatings". I can't wear eyeglasses with any UV coatings, as it affects how I see colors. I only use a clear coating to reduce glare on my eyeglasses. So coatings on things like binoculars and camera lenses are bothersome to me.
I also wanted to establish that I do not know much about optics other than light passes through them and that by using different lenses in different configurations, one can magnify the object you are looking at. As far as how any of that works, I don't know and I really don't want to know. I just want to see a clear view of what I am looking at without dealing with a lot of "Optical Aberrations (see wiki)" such as "pin cushion or barrel distortion", "chromatic aberration" or "Spherical aberration" issues. With my lack of knowledge, I really don't think that I will notice anything except "chromatic aberration", which I call "Purple Fringing". I see it in every camera lens or binocular I have ever looked through, especially in bright sun on backlit subjects. Also I probably will notice softness at the edges of a field of view. As far as my "testing", it's not scientific. I use a resolution test which is a print out of an ISO #2 Resolution chart, on an 8.5x11 sheet of paper. I use the "full parking lot" or "wood Fence" methods for finding out depth of field and I test "CA" on backlit subjects ranging from trees to buildings, to Great Egrets.......
You will find that I am very opinionated, but remember opinions are like something else, everyone has one and they're usually full of $$$$......... Forming opinions based on feelings rather than fact is much easier, because you can change your opinion at will and not have to spend so much time actually figuring out the reasons why.
* I will also be using 2 other binoculars for a "reference". The first pair is my wife's Leitz 8x42mm Roof Prism binoculars (early 80's vintage) and the second pair is a pair of Sears 8-17x40mm zoom binoculars (also early 80's vintage). I use them because it's the only pair I have (donated by my wife) and I have used them for a couple years. I don't use the zoom feature as it's worthless. They are BaK4 prism porros.
I have included Bushnell's advertised specifications here, in case anyone is not familiar with them.

Now, on to the Review and my thoughts:
This was a used product from eBay. It came with the original box, paperwork, Case, Case strap, Bin strap & Cleaning cloth. It also came with a Scheels brand bin carrier, the type that goes over your shoulders to keep from neck pain.
1.- First Impression: when Opening the box: Really nice Case. It's a hard case, Black canvas? With a hard liner. Case strap and Bin straps are new. Bin strap is a wide padded strap. I really like the case. It has a strong zipper on 3 sides and a flap on top (Velcro). When you open it, it has sides which only open part way and keeps the bins from ever falling out, if you're using the strap and the case is at your side. Might be a good way to carry, since I carry a camera too.
Now for the bins.
A.- Fit & Finish: Very first thing I noticed was that the Eye cups were just a little different height. So I looked them over and almost just put them in the case and sold them off. Here's a very weak point of these bins. If you are the type of person who adjusts the eye cups on a regular basis, they will fail. Very poor workmanship. EDIT: I rushed this Review and I had to go to work, so I took the bins with me and tore down the cup assemblies. I now present the true facts and my apologies for misleading information. It was not on purpose.... The twist rings are Metal, not Plastic. On close inspection after removal I find them to be a thin metal. There are three slots in the rings and three screws that act as posts. The slots are the guides as the cups twist. The screws are really the problem here. They are just regular phillips head and they need to be taller. If the heads were taller, then the twist rings would not ride over the heads. What probably happened is that in twisting the cups, the rings got jammed and were forced back down, warping and bending the twist rings, so it made the cups usless. (probably why it was sold). The idea is sound, but the decision to use simple screws instead of ones with a taller head, caused the problem of jamming while twisting. After I took everything apart, I shaped the rings back to some semblance of original. Since I wear glasses, the cups will remain down all the way, so I won't worry too much about it at the moment.
Deep Breath & go on....... The bins are Heavy. Heavier than I thought. The cast body is well done and the rubber coating is also well done. No complaints at all here. The Eyepiece caps fall off. Loose fit. The objective caps are nice. They retain on the bins when opened and they stay put when closed. They are rubber and will fall out of the way when pulled off. Simple approach and well done.
B.- Appearance: Overall these are ugly. I don't like the rubber coated appearance at all, but it's functional and does give an excellent grip. Just not pretty, but functional.
C.- Feel: As I said, they feel heavy. They seem so small in the hands, but are heavy. The grip is excellent due to the rubber and overall I like the way they feel in the hand. Secure comes to mind.
2.- Adjustment: Focus, Interpupillary, Diopter
A.- Interpupillary: Ok, so let's go look thru them! First adjustment was to the Interpupillary distance. This adjustment is Very Stiff and it won't get out of adjustment easily. That's ok by me. Smooth feeling and stiff to move.
B.- Focus wheel - Travel/Feel: Next I picked a sign in the yard about 30 yards away and focused the Left eye to it. Focus is somewhat stiff, but smooth as silk, not gritty or rough. No play that I could find, even doing minute movements of the wheel. Since this is a used pair, I applaud Bushnell for the focus wheel. Very Good!
C.- Diopter Adjustment: Next was to adjust the Diopter on the Right eye. What a challenge! The diopter adjustment is two handed. I had to grab the right barrel in my left hand and turn the adjustment wheel with my right. Very Stiff! It certainly won't go anywhere on its own! Also the diopter wheel will "lift up and turn" independent of the adjustment. Why that is so, is beyond me, but it does. You can lift up and turn the wheel freely and then push back down and turn the adjustment. EDIT: I now understand what was wrong with the Diopter ring and it's solved. The diopter adjustment is made to be easy to turn, but you have to Lift the diopter ring and turn it. If it's down, it is locked and someone had turned it before so hard, that the whole upper lens eyepiece assembly was loose. Well tight, but loose. Anyhow, when the diopter did not adjust, I found out that the whole assembly was loose. After I tightened it, I found the diopter adjustment works smoothly and correctly. (I wonder if the Nitrogen is gone now?).....
3.- The rest of the Story:
A.- Feel of grip: The grip feels good when holding the bins and focusing on targets. Very pleased with the feel.
B.- Brightness: DIM! Compared to my wife's Leitz and my old Sears bins, these bins are Dim. Nothing more to say. Like looking through an f8 camera lens, you camera guys will understand. DIM!
C.- Color: First thought is Bluish tint! All across the field of view. A definite bluish tint strong enough to give a slight cast to everything. Worse at the edges.
D.- Flatness/Pincushion: I notice some distortion in these. It's slight, but it's not a totally flat field. Definitely some pincushion effect here.
E.- Depth of Field: I would say the depth of field is fairly shallow. I haven't tried the "parking Lot" test yet, since it's such a lousy day, but through trees, bushes and the like, I find them to have a shallow DOF.
F.- Chromatic Aberrations: Yes, all over! It's a totally cloudy day and I can see CA on every tree, every twig, building, etc........ Fine and detailed CA on the edges of everything. Of course, even the Leitz have CA, but not as bad as this. I think it might be acceptable to most people, but I have to wait for a sunny day to know more.
G.- Clarity edge to edge: Very Good! Really impressed for the Price Point, just how well these bins do with a really large sweet spot and very little softening at the edges. I believe it's a lot to do with the PC3 coatings.
H.- Resolution: Excellent! For the price point, it's unbelievable. Better resolution than the Leitz. Clearer, sharper image than I would ever have hoped to imagine. Again, PC3 coatings must have a lot to do with it.
So............. Am I happy with them? Yes & NO. Poor workmanship on the eyepieces, blue tint, short DOF and CA.
Will I keep them? Most likely........ Really sharp optics! Beautifully clear FOV, $135.00 is also part of why I will most likely keep them.
They are OK, but I don't feel they are worth $200+ new........... Maybe in the $150 & under category.
