I have always thought that the best reason for having an alpha class binocular is to eliminate any vestige of doubt that might exist in one’s mind. If you are going someplace on the trip of a lifetime, or use your binocular extensively, or simply want the best instrument you can get, then the alpha class is the only place for you to be. The idea of “I’d made that ID if I’d not have been cheap and got a better glass” is not something you will have to contend with.
But, when we get down to just what is seen from use in the field, I think a number somewhere north of 90% of regular binocular users will not be able to separate differences in image between the ZEN class and the alpha class. I happen to be completely confident that if I miss the ID, it’s because I just wasn’t able to make it, not because of need of a better binocular. Nor do I have any particular fear they will self destruct in the field. My peresonal desire for an expensive alpha glass is now gone.
Steve,
I would like to add a bit to some of your commentary, and posibly even refute a bit as well. Unlike you, I AM working for an alpha company and therefore will be immediately suspect, however I came to the company not by way of sales experience or for any professional training in optics, but as a professional birder for nearly 20 years prior. If you would indulge me I want to recant some personal experiences that led me to buy my first Alpha binoc again nearly 20 years ago.
At the time I was working as a seasonal field research biologist bouncing from position to position on average of every 3 months. A labor of love paying "small stipends" and typically providing a roof of sorts over my head. My annual salary at this point was at or below $10,000 US, so if anyone couldn't afford an alpha binoc (representing >10% of my annual salary) it was me. However, I still found this a necessity/priority for the following reasons.
Durability/ build quality - In my first years of working as a seasonal biologist (sitting outside for days on end watching birds!) I purchased the best quality bins I thought I could afford. These were a well touted porro that had a great reputation and ran between $250-300. Fresh out of the box these were excellent and like many, I could see little difference between these and the Alphas when I borrowed a pair for a few minutes in bright sunlight. However, after a couple years of intensive use after suffering a couple failures with internal fogging and similar, the colors I enjoyed fresh out of the box were no longer there. I looked into getting these repaired but costs were almost as much as a new pair. I bought a second pair a bit after 2 years and once again (when brand new) the image was wonderful. Unfortunately, as I used these the image degraded all over again. When I purchased my first pair of "alphas" premium glass after 4 years of this, I used them without fail or notable degradation for the next 15 years in the harshest of conditions!
So here I expand a bit on your own assertion that build quality makes a difference, and suggest that if you buy 3 or 4 "bargain bins" in the lifetime of one of the "alpha"/premium brands then perhaps this isn't as much as a bargain as you thought (or perhaps the "expensive" premium product is not SOO expensive after all). Plus if the image quality deteriorates rapidly on some lesser quality bins, then you are also working through poor views and probably inducing eye strain to boot.
Regarding the issue that most will not be able to note differences, here I have to heartily disagree! I think many convince themselves of this when quickly comparing brand new products at an optics shop or show (I know I did for years ;p ). However, these comparisons are often done quickly. Also, at the shows I typically work, it seems people invariably it's mid day and people want to take these outside or peer out the windows. In bright sunlight average differences between optics at all levels are less noticeable.
I remember my first conscious notation of the power of the premium bin. I was standing shoulder to shoulder with a buddy who had just made the jump and we were staring at a Northern Saw-whet Owl roosting against the trunk of a thick Blue Spruce in a dense grove of conifers. Through my decent porros, I noted a shadowed ovate shape brown and white markings with little contrast. My buddy next to me with his brand new optics that he'd paid 4x more for than me with mine, was yammering on about the colors, and how amazing the feathers were noting it looked as though it had "long eyelashes". My bins were 8.5x his 7x yet I could not see the detail he did. I knew I'd regret it in my wallet but I asked to see.... It was incredible!... as though someone had put a sunlight spot light on the bird .I was seeing amazing color contrast and details just not visible in my bins. I applied for credit and got myself a pair a week later.
Additionally, you can see the same effect at ANY twitch anywhere in the world. Invariably, someone will set up a bargain scope and not be able to make out details be it true colors, or to resolve details on a rare bird then move to a high-end/premium scope set to the same power and be able to see all of this. It happens all the time. So here I say that absolutely there will be times when a bargain optic will not be able to resolve the detail necessary to make a positive ID and the premium optic will! Especially in low light or with distant birds (again at close range in full sunlight this will be less apparent).
Of course, as I said upfront I have a vested interest and my opinions will be suspect... my company stands to gain if more people buy premium optics! However, I will challenge comments like this and ask that before anyone makes these you do the following:
1) take note of which optics are still in use after 10 years or so. I would also welcome all to compare a 3-4 year old "bargain binoc" to a similarly used premium optic and see if the differences are still not easily apparent.
2) Give a premium optic a REAL test not for just moments but try to take advantage of a situation where you can actually borrow a pair for a full day of field birding. Compare your overall experience to include eye comfort, and eye fatigue.
I'd suggest that very few individuals wouldn't find the difference extreme after going BACK to their bargain binocs! ;p I know similarly when I received my sample of our new scope with the revolutionary wide angle zoom eyepiece. I could tell there was superior resolution immediately and appreciated the wide angle view, but it wasn't until I'd used it for a week and went back to it's predecessor (an EXCELLENT scope) that I was absolutely floored by how acutely aware I was of the narrower field of view.... Similarly, I carried a 6.5 pound tripod/head combination for almost 17 years without any problem. Recently I switched to a 3 pound tripod & head combo. After carrying it for a year I accidently picked up someone else's scope with the same old tripod I'd carried everywhere for years. It was FUNNY, I felt as though I were trying to curl bricks. I'd grown so accustomed to the new, improved lighter weight that this old setup was painful!
At any rate, that's my sermon for now. Whatever your pricepoint, I think it VERY safe to say that in most cases you get what you pay for in optics though and to get maximum enjoyment out of your time afield get the BEST quality optics you can. If you're eye doctor shows you are seeing 20/20 (beit corrected or naturally) and others around you are making out details or true colors on birds you can't see well, perhaps you should consider that there is a difference in the optics you choose.
Good birding all,
