PENTAX PCF 7X BY 35MM
Six years ago I arrived in Gillete, Wyoming without my gun case and binoculars (the airlines momentarily lost it).
I was able to borrow a gun from the outfitter but the binoculars offered didn’t appeal to me, so I looked for a good one in the store where I purchased my out-of-state license.
I really can’t understand how any serious hunter can spend one grand in a rifle and scope and then turn around and pick up a $39.99 binoculars from the “on sale” rack.
To me the binocular is the “hunt”; I spend most of the time in a hunt glassing for game, looking for that tell-tale piece of fur between the vegetation, that antler sticking out of the bushes or that liquid shine of an eye in the bushes.
For me, glasses that are sharp, bright and have good definition are imperative to the success of the hunt, after all if I see something that appears to be an antler or horn sticking out of the brush, I want enough definition in my optics to tell me that it is really an antler and not a just a weathered branch.

Good optics cost money, sometimes a good deal of it. A bargain is not found in the price, but in the quality of the optics that you can get for a predetermined amount of money that you are willing to spend.
For that reason when you are in that store comparing binoculars to each other it is necessary that you know what you are looking for regarding the quality of the glass inside the binoculars.
A good company name will have glasses of different prices; today it seems that even the cheap brands will advertise that they have Barium Crown glass (BAK4) and coated optics.
What you have to look for in the box that comes with the binoculars are those advertisings that say they use fully multicoated lenses. This coating is a bombardment of the glass with anti reflection particles of magnesium fluoride or other similar compound, the deposit will change the color of the glass to a blue hue or ruby or green, and what is does is sharpen the image and eliminate reflections that robs the light entering into them.
Cheap brands will coat once and only the outside of the lenses, what you looking for is fully multicoated lenses (as much as seven coats are applied) in all of the inside and outside surfaces, good brands will advertise the fact in the box or literature that come with the glasses.
Looking through a good glass, you will see that an image is sharp and well-defined, while the image from a cheap binocular will be soft and fuzzy.
Brightness in a binocular when you are in a store has to be checked by looking into dark corners of the store and trying to read some labels. The letters in those boxes will appear dark and fuzzy when looked at through cheap binoculars, while with a good set you will notice how the letters are sharp, lighted and well-defined. Don’t look out of the window to a bright street: it will tell you little about the capabilities of the binocular to perform in poor lighting conditions.
Some brands make waterproof and fog-proof binoculars by using good seals and charging the interior with an inert gas such as nitrogen, as it is more difficult to make a good seal in binoculars that have more parts than rifle scopes, and if waterproofing is important to you, consider a good name brand that will stand behind its warranty.
Look toward the borders of the glass to see if you can find any distortion in the picture. You may find some, as only the very best glasses are free of it, so just consider the brands that have the less of it.
Now that binoculars are designed by an optical computer program, it is rare to see other optical aberrations unless you are looking through a set of very cheap glasses.
That day in the Wyoming store I spend a good hour looking at different binoculars. I walked out with a Porro prisms model from Pentax (Porros are less costly than Roof of the same optical quality). I think I paid about $175.00 for it, and I never have regretted my selection.
It is just a coincidence that I selected a Pentax, as I was looking for optical quality that can be met by many brands: Bushnells, Nikons, etc. It is just that I have used Pentax cameras and I have been awed by the quality optics they have.
This one is a 7x by 35 mm Pentax PCF Porro prisms binocular and at 28 oz. not that heavy, Porros are always more bulky than roof prisms, but this particular model has good ergonomics and at 6” long by 5 ½ “ it is quite compact for a full-size glass.
This particular model have a focus lock on the focus turning wheel, when you have achieved the focus you can lock it in place by sliding the lock into place, very neat,
The right ocular has detent clicks in the diopter adjustment for the eye, another very neat feature that speaks attention to detail and innovation in the design.
While most Porros binoculars have a couple hinges connecting to the center shaft, these are designed with a more solid, all-body mass to center shaft, more like a quality roof prisms. I don’t see this binocular get knocked out of alignment by rough use anytime soon.
The glasses I have, had been replaced in the Pentax line for the new PCF WP II 8x40, and they are even better as they feature helical adjustment for eyeglass wearers instead of my old style fold down rubber eye guards, and I have noticed that they come with a rain guard for the ocular lenses tethered to the neck strap while my model has the easy-to-lose plastic caps.
As I want my optics dry and clean all the time, I had to rig my glasses with some tethering ribbons for the plastic caps attached to the strap for the oculars lenses and to the center screw cap for the objectives lenses.
And what’s more, the price of the new Porros PCF is still about the same, even lower at internet discount houses.
The exit pupil of an 8x by 40 mm is the same 5 mm as the 7x35, so these glasses should perform very well in low light situations, much better than those toy 8x20 daylight only binoculars that most folks seem to buy these days at the department store.
Good quality binoculars are a joy to use. If you can not afford the quality popular roof prisms that are in the market for about $300.00 USD, you owe yourself to look for a quality Porro prisms that for about half the price will give you just about the same optical quality.
Life is good!
