Thanks Neil, for the review. I was sorely tempted by your review of the Svbony 8x32 ED, but now it appears tha I absolutely must get this binocular!

They look a lot like my scoopX 10X42 and I believe oberwerk also has a similar model. It wouldn't surprise me if they were all the same optics. I did a little shoot out with my scoopX 10X42 and Oberwerk 11X70 a couple weeks ago. The 11X70 won big time. Aperture rules in binocs too. The 10X42's were much easier to hold steady by hand though.

I'm more curious about the magenta lens coatings which appears to perform well, than the binoculars itself. They don't appear to be the ruby coatings that were mentioned on CN used on cheap binoculars. Did the chinese cracked the Zeiss SF coating's chemical formula using chemical analysis and/or derived a cheaper/simpler alternative? If so, we might see a proliferation of such magenta coatings, instead of the usual green coatings, on more MIC binoculars in the near future.

Thanks Neil: nice review! I am curious about where the manufacturing country "Honk Kong" is though!
Keep up the great work, and all the best.

The AR coating can be made to have any colour appearance desired but whether it is effective or not is a different story. As to what is technically better - green, or purple/magenta/red, or some other colour - I can't actually say. It does depend on the actual glass material as each change in refractive index requires a different coating application if it is to be optimum, which of course increases the cost a lot, so many companies might apply the same coating composition to all lenses.
In practice, AR coatings should be mixed so that the colour balance comes out neutral (broadband efficiency), but I think when the best modern multicoatings are dealing with only a few fractions of a % of transmission per layer, then it is inconsequential to let the final bias/dominant colour on the top layer be something like deep red because any resulting tint (it will pass more blue) may not be perceptible to us when using them.
This page shows that flare is actually not that different given many different coating designs https://mbphotox.wor...12/24/flaring1/ although clearly the Zeiss T* lens comes out on top, it will be due to the greatest care and attention paid to the rest of the design such as internal blackening, the shape and placement of lens elements, the use of baffles. Some otherwise good eyepiece designs are just destined to produce clear ghost images due to backlighting or reflections from internal baffles.
I mean, Zeiss T* is not always deep red - in fact I'd say rarely so. Search the term on Google Images and you'll see they have also used every colour of coating under the sun: Lime, mint, aqua, orange, purple, deep blue.
More than likely what has happened is, the Zeiss binoculars have been used as the benchmark for the top Chinese optics and simply copied as much as possible, and thus they use glass types with similar refractive indices, which would call for a similar application of AR coatings to match. The other reason for red may just be for marketing purposes on behalf of both companies. Deep red is an undoubtedly attractive colour which stands out as unique from the majority of multicoatings on the market.

There is also a 10x50 version.
42% more light grasp than the 42mm versions.
similar FOV
longer eye relief - 17mm vs 15mm
but heavier - 951g vs 698g (36% heavier)
I have a Bushnell 10x42 Legend M which I find an excellent Astro/daytime binocular.
I think the 10x42 mm would be redundant.
Also have the APM 10x50 ED which weighs 1380g.
The Svbony SV202 10x50 is much lighter (45% - 429g nearly a pound lighter).
No reviews on the 10x50 version.
Very tempting !

I ordered this and then cancelled my order. I have a Canon 12x36 IS II, which I got from ebay for cheap as a gooey mess, as the rubber cover was melted. I have since cleaned them up and they work well. I canceled because I don't use bino's often, and the image stabilization puts the Canon ahead of these. I was looking for something wider. But my Canon is hard to upstage for cheap and good. Would one of these compliment the Canon 12x36, any ideas?

Probably not the 10x42. Too similar specs.

The 8x32 would be appreciably wider, it could be a good complement to your 12x36.

Wait until the review of the 10x50ed is out and then perhaps you can reorder if they on par or better then the 10x & 8

Thanks very much for the feedback everyone. It was a very enjoyable experience putting this together.
Interesting info regarding the 10 x 50 ED model. One question; are these phase corrected? Maybe I missed this but I don't think I saw it on the blurb??
Best wishes,
Neil.

Guys
The Svbony family is now complete!
I share some pics for size comparison. I will be testing the newly added 10x50Ed once I spend some time using it under different light condition and stargazing. Keep an eye for a YT video.
After a quick check the standout feature is the focuser is even smoother than the 10x and 8x also the view is incredibly immersive thanks to the larger 24mm eyepiece and 17mm eye relief.

Good for you Opticsfield!
Looking forward to hearing your opinions on the 10 x 50 ED.
If the 50mm model is half as good as its 42mm sibling, then you have a real winner!
Regards,
Neil.

My Svbony journey started by acquiring the 8x32ED model after reading Neil English’s highly detailed review! I was hooked by his finding and decided to dive in to Amazon and buy it.
The 8x32ED proved to be a little gem to a point where I decided to do a YouTube video to showcase its performance. Fast forward one week later and I decided to purchase the 10x42ED and it was a revelation! Remarkable binocular for the price! For a detailed review, please refer back to Neil English’s review and head over to Youtube for a closer look.
Today’s review is mostly about the bigger brother 10x50ED
I had to complete this set to find out if Svbony had actually found a magical formula to produce binoculars that outperform brands costing triple the price and some more.
Make yourself comfortable, grab a tea or a coffee as this might stretch a little.
Out of the box nothing has changed, the same packaging as 8x32, 10x42 witch is a good thing. The accessories remained all the same across the three models.
Fist thing first: a flashlight test revealed that all Svbony models produced a clean image, free from any internal reflection or floating doughnut. This consistency across the range indicates that Svbony payed a lot of attention to their internal blackening and evenly applied coatings.
Despite the slightly bigger body, the 10x50 it remained very comfortable in the hands, thanks to its well distributed weight of 950g which put it in the lightest category of a 50mm lens(which usually weigh in at 1000g).
I always thought that the 10x42 had one of the smoothest focusers out there despite being on the slow side however, the 10x50 takes it up another notch on this pair. It was faster and smoother then any other binocular I have tested. So far, things are looking promising and I am starting to think that this pair is another keeper/winner in the Svbony arsenal.
The eye diopter was also very refined and as smooth as the focuser. It locks in to place with no back and forward movement.
On paper I was most exited about the eye relief and the larger eye piece and boy they both delivered! I wear glasses and I cannot operate binoculars with anything below 15.6mm so the 17mm quoted were a god send and it made my viewing as comfortable as it gets.
I couldn’t contain my excitement so I decided to drag the new toy out for a quick drive in my local field. It was the sort of weather condition that can be challenging for any binocular, a blanket of low grey clouds and light fog that the 50mm had to conquer. My first impression was very positive, the image was incredibly immersive and the extra light was evident. The biggest difference from the 10x42 from a glasses wearer prospective is the ease with which my eyes aligned with the pupils and be fully immersed in the fov which stands at 106m/1000m which compares very well with the likes of Swaro SlC quoted 110/1000m
Close focus quoted by Svbony at 2m but I can happily confirm that they meet that claim and outperform Swaro EL 10x 50 WB: close focus: 2.8m.Other alphas like the Leica Ultravid and the Zeiss Conquest 10 x50 T come in at 3.2 and 3.3m so jolly good close focus on these Svbonys!
Back to the image quality; whilst looking at trees and green vegetation in the distance, it instantly reminded me of the colour accuracy and contrast of the 42mm model. Punchy colours that never feels washed away regardless of the light condition, plenty of contrast and no sign of CA at this point.
The shot below was taken handheld with my iPhone in windy condition.
My sharpness test couldn’t be conducted without the 10x42 being the benchmark. The 42mm has a 4.2mm exist pupil and the counterpart has 5mm. I focused both binoculars on a brick wall to see which can resolve the sharper lines and to my surprise the 42mm did edge the 50mm by a hair. Both binoculars produced a sharp image to about 85% from the field stop.
My star test was another WOW moment and this is where the 10 x50 really rocked! Looking up at Cygnus showed countless Milky Way starsI was blown away by its light gathering power even from my light polluted North London home. Stars remained nice and sharp across the vast majority of fov.
Very pleased indeed!
Cannot rate higher enough!

A nice review! Do you mind including some more pictures taken through the binoculars? Maybe a powerline, a landscape, the moon or a view towards the setting sun? Thank you!
