Google translation of a Chinese blog about the Pro-Optic 8x42 8.3
It's barely readable I'm afraid.
It has lots of photos I don't reproduce here
The
fourth photo suggests the FoV is 7.8° not 8.3°
The
last photo shows the bin sitting on a catalogue for...

走马观花，谈几点简单的印象和建议做工方面： Cursory talk about a few simple impressions and recommendations of the working areas:
1、饰皮采用黑色压花加塑橡胶，质感细致，防滑不错；试样版饰皮接缝较宽在成品版已较好的解决；建议如果采用彩色饰皮会提升成品的灵动感。 1, decorated with a black embossed leather plus plastic rubber, texture detail, a good anti-skid; sample version of decorated leather seams in the finished version has a better wide solution; recommendations, if adopted will enhance the finished skin color ornaments spiritual dynamic.
2、重量轻型化思想得以贯彻，采用了镁合金金属镜体，重量感觉与航2差别不太大，尺度控制合理，属于适合携带的日用型产品。 2, the weight of light-based thinking can be implemented, using a magnesium alloy metal mirror body, the weight difference between feeling and freedom are not two large-scale control is reasonable, are suitable for carrying household products. 镜筒较EL8＊32略粗，握持充实。 Tube a little thicker than the EL8 * 32, grip enrichment.
3、在采用无中轴设计和中拨轮调焦的同时，对屈光度调节采用了专利单指按压扣技术，使得调焦完全可以单手独立完成。 3, in the use of non-axial design and the Jog Dial, while focusing on the diopter adjustment uses a patented single-push button technology that makes focusing entirely with one hand alone. 这一点较莱卡、蔡斯、施华的中焦轮双指抽拉完成屈光度调节更加便于单手操作，为亮点之一。 This is compared with Leica, Zeiss, Silva's focus in the completion of round two fingers Withdrawing diopter adjustment easier one-hand operation, as one of the highlights. 实际操作感觉确实很方便，单指压的力度也适中，调节顺畅到位。 Hands-on feel really convenient, just referring to the intensity of pressure is also moderate, regulate and smooth in place. 中调焦轮转动压盖不随动；建议按压扣最好有个着力面大些的顶帽，使得指压感能更好些。 Focusing rotation of the gland is not servo; suggested the best push button has a bigger focus on the top surface cap, making sense of that pressure can be better.
4、旋升式眼罩旋转顺滑、三档调节，挡位感很明确。 4, spin-spin smooth eye-lift, third gear adjustment, gear feeling is clear. 个人感觉较蔡斯FL好，顺滑度接近施华SLC；挡位较蔡斯和施华清晰。 Personal feeling better than Chase, FL, smooth is nearly Silva SLC; gear than Chase and Silva clarity.
5、中轴转动力度感合适；缺点还是有润滑油渗出状况。 5, a sense of right axial rotation efforts; shortcomings still have oil leaking condition.
6、观察内部金属件表面光洁程度和规整度好，外表亚光漆面均匀。 6, observe the internal metal parts and smooth surface extent and regularity is good, uniform appearance of matte finish.
光学方面： Optical aspects:
1、采用了多层的全表面镀膜，据介绍采用了相位模，外侧镜片表面采用了憎水膜。 1, using the entire multi-layer coating on the surface, it is reported using the phase mode, the outer lens surface of the water-repellent membrane. 目镜为紫红色，物镜为墨绿色，反光不大。 Eyepiece as purple, dark green lens is, is not reflective. 物镜的绿色膜比较老套给人有些失望，反映出的膜色不够丰富。 Comparison of old-fashioned green lens gives the film a little disappointed, reflecting the film and color-rich. 用观测白纸及比对法观察，偏色倾向为褐偏粉色，色感比SE、SW－H等等要重，与战神差不多，但透光率不如战神8＊30，（由于存在反射光路，屋脊的透光率通常低于保罗）。 White and compared with the observations were observed, tend to the brown side pink color cast, color sense than the SE, SW-H, and so we must pay attention, and Mars is almost, but not as good as God of War light transmission rate of 8 * 30, (due to existence of the reflected light path of the light transmission rate is usually lower than the roof Paul). 强烈建议能够调整反射膜系及选择色泽丰富的增透膜系，以改善偏色状况和有效提高透光率。 Is strongly recommended that the Department can adjust and select the color reflective film AR-rich layers, in order to improve the color cast situation and effectively improve the transmission rate.
2、色差校正效果好，能达到中高端镜子水准，ED片的采用还是有必要。 2, chromatic aberration correction effect is good, can achieve the standard of high-end mirrors, ED tablet use is still necessary. 是这个镜子的亮点之一。 One of the highlights is the mirror.
3、畸变校正和平场校正效果比较好，像质退化极其边缘。 3, distortion correction effect of the peace better field correction, image quality degradation is extremely marginal. 也是这个镜子亮点之一。 This mirror is also one of the highlights. 但与佳能10＊42IS比较，平场过渡还有些差距，边缘1／4开始有轻微滚球效应。 But with the Canon 10 * 42IS compared to flat-field transition was also some gaps, edge 1 / 4 small bowls began to have effect.
4、属于大视场设计，视野较为开阔；成像清晰度与锐度不错。 4, belong to large field of design, vision is more open; image clarity and sharpness well. 但由于观测环境限制，没有进行过细的比对。 However, observational constraints, no meticulous compared.
