A Good Buy
Ron from Yreka, California
I'm new to binoculars (good ones, that is) and so I can't speak in technical terms like those who are experienced can. This is my first serious purchase of binoculars, having had a pair of "cheapies" for years. I have been able, though, to look at some pretty nice ones and compare in stores. For the money, I chose these over others, some costing quite a bit more, because the view through these Granite ED's is what I would call more "pure". There were others that were quite nice as well, in terms of sharpness, clarity, etc., but with these Celestron Granite ED's, I felt there was "less" between my eyes and what I was looking at, making the view seem much more real and natural, as well as being very easy on the eyes. That's the best way I can explain it, and because of that, I would choose these again over other very nice binoculars that I looked at. I presume that a lot more money would have to be spent to top these (for me) and so I consider these binoculars to be a really good buy. Also, it's nice to find a good place like Eagle Optics to buy from, and I will buy from them again.
Not so sweet
Opticz from US
This is specifically about the 7x33 variant of the Celestron Granite Series, evaluated in May, 2015. (I have no experience with other models of the series.)
I own many binoculars already, but I was attracted to the 7x33 because it has one of the largest field of views (FOV) available in a binocular. The only other comparable FOV's that I am aware of are the Zen-Ray 7x36 and its sibling, the Eagle Optics Atlas Optics Intrepid ED 7x36 Binocular.
Unfortunately, after setting the diopter adjustment, it was quickly apparent that the Celestron Granite 7x33 has a very small sweet spot. Also away from the center of the field, the view deteriorates to such a degree, that I found it to be very distracting. I was so turned off by the effect, that I decided to not evaluate the binoculars any further. I cannot recommend the Celestron 7x33's at all.
I tested the Atlas Optics Intrepid ED 7x36 Binocular at the same time, and the Atlas has a more reasonable sized sweet spot. The sweet spot of the Atlas is still not so big, but at least it is reasonable.
Celestron "Granite" 7x33 ED
D. Paddison from Whitby, Ontario, Canada.
The improvements that continue to be made in binoculars and then made available to buyers at a reasonable cost continues to amaze me. What you get here is a light, well balanced and pleasant to handle binocular of very high optical quality. It provides EXCELLENT image sharpness/color saturation, with a large field of view which is very sharp in the 50% of field gently tapering off towards the edges with no rolling ball effect. Although this is subjective I found they gave a nice 3-D effect when looking a certain things much like a porro prism binocular. Also with them being 7x (which I prefer) they are a little easier to hold steady than standard 8x binoculars without loosing any image details. I only have two minor issues with them and they are a) the objective lens covers tend to flop closed if you are doing any direct/close to direct overhead viewing (easily correct by simply removing them for prolonged overhead use) and b)the focus wheel although very smooth and precise could be a little "grippier". Hopefully Celestron will address the lens cover issue/focuser in the near future as they are both easy fixes. They just need to use a little softer, more pliable piece of rubber for the tethered piece that connects them to the binocular and add a couple of extra rubber ribs on the focuser. Don't let my minor "quibbles" with them put you of trying/buying a pair because it certainly didn't stop me. Other than those two things I could find nothing else to find fault with especially when you facto in their price. The eyepiece rain cover is very nice..soft, pliable and fits perfectly. Eye relief is more than adequate for non-eye glass wearers (I can't speak to those that do). The case, neck strap, and included included harness are all excellent as well.
There are many things that factor in to make a great binocular. Generally cost is a good indicator of the quality you'll get but that alone isn't the only thing to consider. I've tried many high priced models that although great to look through, were missing something in ergonomics, looks etc. On the other hand I've held some inexpensive ones that although optically they fell short, in ergonomics/appearance they were great. Although it's personal individual preference that makes our decision when buying, when a manufacturer is able to hit the "sweet zone" and bring everything together that makes a binocular great, and I think Celestron has, with a couple of tweaks, hit the proverbial "home run" with these. I whole heartedly recommend them to anyone looking for a GREAT all-round binocular but doesn't want to "sell the ranch" in the process.
Celestron Granite 7x33 ED
D. Paddison from Whitby, Ontario.
I went out to Guelph Ontario the other day home of the Canadian dealer for Eagle Optics to look at/evaluate some binoculars (if your ever in the area drop in. They are well stocked and the staff is friendly). As usual I looked through all the "green ones" just for fun but as usual they where still priced out of my league :) I was primarily interested looking at the new Ranger 8x32/8x42 ED's which I gave a thorough "once over". Then I remembered reading a review of the Celestron Granite 7x33 ED's which they had in stock. A 7X roof prism has always intrigued me and after looking through/evaluating them I forgot all about the Rangers and focused on the Granites. The 7x33's have a VERY sharp central field of about 50% and the rest, although a little softer (can't be SV sharp in this price range and you don't look at the whole field all at once in a wide field bin anyway) is more than acceptable especially when combined with their beautiful, wide, immersive field. They are light, well built, handle beautifully. The center focus wheel is very smooth and precise and goes from near to far adequately fast. When you are focusing on something you KNOW when you're in focus, no back and forth to find it. Although subjective, I found them to give a very nice 3-D effect when looking a certain things, almost like a porro prism binocular. One thing I like about a 7X binocular is that with virtually no difference in image scale and the detail that can be seen, they provide a slightly steadier view to an 8x which I prefer. I can't speak to people who wear glasses but for me a non-eyeglass wearer the eye relief is very comfortable and more than adequate. The case and neck strap are great and as a bonus they come with a harness! The only real "weak point" I've been able to find with them so far is the tethered objective lens covers tend to flop closed when looking almost at and directly overhead but it's not a problem in any other observing position. If you're going to be doing a lot of overhead observations for extended periods just unplug them. In the mean time perhaps Celestron will correct the problem and if not (birders being an ingenious group!)there are third party solutions out there. Also the centre focus wheel could have been a little "grippier" but it's more than adequate as it is.
To summarize I've been more than pleasantly surprise with mine. These are an outstanding little binocular at a great price!
Spectacular Field of View
Jaymie from Santa Fe, NM
Having always been a fan of lower magnification binoculars due to their significantly larger field of view, I was eager to try these bins and see exactly how good their advertised 477' FOV was. As an owner of a Swarovski 8 x 32 EL SV, I certainly did not expect them to be even remotely in the same league optically given the price differential (the swaros cost 7x as much!). Well, I was shocked to find these bins possessing many superlative qualities, not the least which was their outstanding image quality. While certainly not at the same level as the Swarovski (the Swaro shows sharpness to the edges), I'd say these binos produce an image that is very close with 75-80% of the field of view very sharp and only a very subtle loss of sharpness towards the edges. With a field of view this big, I'm not going to be looking at edges anyway. Like the Swaros the ergonomics are excellent (the bridge design is very user friendly), and the focus wheel is easy to use. Honestly these are the best value binocs I have ever seen, and not far off from the alphas. Makes you question how much you really need to spend to get a decent binocular!
Chris from High Point, NC
Have a pair of Pentax 10x50's, and was looking for something lighter that I could take on trips. If you just want to look at the sky, the 10x50's show a brighter image, though a smaller field of view. I selected the 7X instead of the 9X for field of view and am not sorry I did that. Even looking at the night sky, so much of the Cygnus star cloud is visible the view is very pleasant. For daytime use, I don't think you can beat these binoculars. View is bright and wide and the 7X delivers enough magnification for vistas, birds or other wildlife. Though not at light as the Nikon Monarch 7 8x30's, the weight is very comfortable. I am very happy with these binoculars and feel that for daily use (hiking, birding, vacation, etc.) they can not be beat.
