Bijia 20-60x60 Zoom Monocular Review from GearBest. Review on All-Coupons.biz

After I had purchased and used these Bijia binoculars http://all-coupons.biz/review/114/ I wanted to get something bigger and more powerful. As I wrote earlier, the binoculars were of high quality and worth admiring. So for the next purchase, the choice has stopped on this brand.


By the way, Bijia has a great choice of optical devices ranging from magnifying glasses, and ending with night vision devices and astronomic telescopes. Bijia also has its own store on AliExpress, but the same monocular there is 20% more expensive than on GearBest https://ru.aliexpress.com/store/product/BIJIA-2017-bird-watching-monocular-BAK4-prism-night-vision-waterproof-HD-zoom-telescope/1815501_32776111918.html.


As far as I remember, it is already the second case when items in retail stores on AliExpress are significantly more expensive than on GearBest.
So, briefly about the Bijia binoculars 20-60x60. This is a new 2017 model. Schematically, the Bijia monocular 20-60x60 is "half" of the binoculars. Here, the system of prisms Porro BAK-4 is used, which, I think, is the optimal solution for the size/increase index. In fact, it can also be called "telescope", but we've learned that the telescope is used to observe celestial objects, has a larger size and magnification characteristics and it is more stationary.


The difference between this Bijia model 20-60x60 from the binoculars is in a higher magnification and that the magnification can be continuously adjusted from 20x to 60x.

Unboxing

After the binoculars were delivered I was immediately pleased with the size of the package. Since for the optics, in theory, the bigger the size, the stronger aperture and magnification factor. Bijia 20-60x60 monocular was packed in an additional box of impressive dimensions. For size comparison I put what was at hand next to it:

A little unusual for me is that there was a GearBest logo-sticker. I have never dealt with it before.
When you open the parcel you directly see the box with the monocular. The rest of the free space in the box was filled with some bubble wrap.

Thanks to the good packaging, everything came in one piece. The box came through the shipping and looked good. I should also note that it is well printed and has a high quality full color printing.

Open the pack and see a fabric bag for storing and carrying the telescope. The bag is well stitched, no flaws were discovered.

So, open it and get the contents of the bag. Monocular and tripod are additionally packed in separate bags to avoid scratches during shipment.

I would like to also note that the bag is separated inside into 2 sections by a Velcro foam insert – for telescope and tripod, in order to avoid scratching during transportation.

In addition to the monocular and tripod, there are some instructions and cleaning cloth for the optics in the bag.

To my surprise, the instructions were worse than packing. It is in English and it provides some general information for several models. The main thing you need to remember – never try to look at the sun through magnifying devices, because even a split second can lead to vision loss.

The tripod is quite heavy and can help you to explore telescope first. But in practice, its function is quite limited. I used it only one time when I was doing the photo shoot for the review. After that, I used an usual tripod for the camera. This is another huge plus of Bijia 20-60x60 Monocular, that it has a standard connector for a tripod. The head of the tripod is fixed, and can be adjusted only by the angle. Horizontally it rotates freely without fixation. On the plus side – there is a rubber pad on its head for better fixation. By the way, the ends of the legs also have rubber tips.

Monocle has a size of 34cm * 8cm * 14cm. The case is completely covered with rubberized plastic, so it is kept in hand and does not slip.

All the optics has a plastic cover, in order to avoid damage during storage.


On the eyepiece, there is a scale 20x 40x 60x for smooth magnification changes. A central tool on its body adjusts the contrast of the image.

Let`s test its magnification. As in the binoculars review, we’re gonna take the same objects to zoom and compare the results of photographs using the Bijia 20-60x60 Monocular. Unlike binoculars, it was not so easy to fix the camera on the monocle. For regular photos you will have to purchase an adapter like http://www.gearbest.com/binoculars-and-telescopes/pp_598021.html

Pictures from the previous binoculars review without any zoom:

At once I would like to say, that I took pictures on the same phone as it was in that review. But I could not fix it normally, so the pictures were taken from hands. In this regard, the picture is not very clear, in reality, you can see everything clearly.
So, a window photo, using the Bijia 20-60x60 at 20x zoom.

Crop of the window at 100% zoom level. The difference with binoculars is immediately noticeable, even at minimum zoom.

Now measure the dimensions in Photoshop and determine how much does the Bijia 20-60x60 Monocular really magnify.
For the 20x zoom the size of the window was 231px * 419px = px2 96789
From the previous review the area of the window without magnification was 276px2. Now, the magnification is 96789 px2/px2 276 = 350x.

For the 60x zoom the measured size of the source is 720px * 1194px = 859680 px2. Let`s calculate the linear zoom 859680 px2 /px2 276 = 3000x.

The conclusion is that even at the lowest zoom, the Bijia 20-60x60 Monocular increases nearly 8x stronger than binoculars 20x50. At maximum zoom, the monocle is much powerful than 70x.

Conclusion:

The Bijia 20-60x60 Monocular turned out to be better than I even expected.
On the plus side can be identified:

  • A clear picture at all magnifications;
  • Infinitely variable zoom;
  • Standard connector for a tripod;
  • Good build quality in everything: from coated optics and case to smooth adjustment of focus and zoom;
  • Stable as brand – bot optical instrument turned on high.

By cons, there are only cheap-made instructions.

And a few words about the aperture – in the dark you can easily observe bright objects. When there is insufficient light you can feel a drop of brightness with increasing multiplicity. The higher is zoom, the dimmer is the object. In daylight the brightness change is not felt.
In fact, the magnification allows you to read printed phone number on a A4 sheet from a distance of 190 meters.
Bonus crop of the moon shot also from hands:
