Review: IOR-SA 7x40 vs. Zeiss Jena EDF 7x40 vs. PZO 7x45
by Holger Merlitz  翻译 北旅论坛footway

After collapse of the East Block of socialist states, their military optical equipment became available on the surplus markets and is nowadays easily accessible via Internet on Ebay or via professional dealers. It was quickly realized that the quality of binoculars used in the Warsaw Pact was comparable, if not superior, to their counterparts in the NATO. Especially the devices made by Carl Zeiss Jena and employed by the East German NVA immediately gained a high reputation among professional users and collectors as well. I refer to my reviews of the DF 7x40 and the EDF 7x40. But there were other binoculars, too, some of them less known by today and nevertheless of amazing performance.
冷战期间的东方社会主义国家崩溃后，军用光学装备在剩余物资市场能获取到，现在在互联网上通过Ebay或者通过专业经销商很容易得到。很快就了解到华沙条约组织使用的优质望远镜与北大西洋公约组织的相比，即使不更优秀，也处于相同水平。特别是卡尔.蔡斯.耶拿（Carl Zeiss Jena）生产的装备东德军队的镜子迅速在专业用户和收藏家那获得很高声誉，我指的是评测过的DF 7x40 和 EDF 7x40。但也有其它望远镜，现在的知名度不高，却有惊人的表现。

This review compares the Romanian IOR-SA 7x40 with another version of the East German EDF 7x40 and the Polish PZO 7x45. All three of them are full-fleshed military binoculars with a thick rubber armor and reticle. The oculars are individually focused and sealed so that these glasses are water resistant. As common for Warsaw Pact binoculars, they could be equipped with a detector for active infrared sources. The EDF and PZO contain such a detector, the version of IOR presented here is without.
本次评测比较了罗马尼亚的IOR-SA 7x40，东德的另一版本EDF 7x40，波兰的PZO 7x45。这三个都是完全的军用镜，都有包胶和刻度线，双目调焦，有防水性能。作为华沙条约组织望远镜的共性，它们都有红外光源探测功能，EDF和PZO都有，当前评测的IOR没有。


Fig. 1: The Romanian IOR-SA 7x40
1号：罗马尼亚的IOR-SA 7x40

There exists a detailed review of the IOR 7x40 binocular by Scott Powers. According to that, IOR is a Romanian manufacturer, located in Bucharest and making optics since 1930. Apparently, they order their quality glass from the German Schott Glaswerke GmbH. This binocular is used by the Romanian armed forces, but seems to be sold to the Soviet army, too. Its serial number indicates 2000 as year of production. The IOR exhibits some similarity to the East German DF 7x40, but is less bulky and slightly less heavy. In fact it settles very nicely in the hand. This instrument comes with yellow filters which are stored in compartments inside the objective lens covers. Although the eye-relief of 20 mm is generous, a use with spectacles on could proof problematic: The contoured rubber eye cups fold down, but then the eye-glass rests on a metallic ring. The device is nitrogen filled and fully water-proof. I have found dealers selling them new in the US for about $350 (see links below), but none in Germany. On Ebay the IOR 7x40 can be found second hand for 250 Euro in good condition.
Scott Powers对IOR 7x40已进行了详细描述，据此，IOR是位于罗马尼亚首都制造商产的，该厂从1930年生产光学设备。显然他们从德国Schott Glaswerke GmbH订购了优质玻璃。这镜子装备罗马尼亚军队，但似乎也卖给苏联军队。本镜的序列号中的2000指明了生产年份。IOR显示了与东德DF 7x40的某些类似性，但较小较轻。实际上拿在手中非常舒适。它配备黄色滤镜，保存在物镜盖里。虽然出瞳距离20mm很大，但戴眼镜使用被证实有问题：波形眼罩折下后，眼镜就只能贴在金属圈上。该镜是充氮防水的。我知道在美国新的此镜被卖到350$左右（见下面的链接），但德国没有卖的。在Ebay上，状况良好的二手IOR 7x40卖到250欧元。


Fig. 2: The East German NVA EDF 7x40
2号：东德NVA EDF 7x40

Being built as a roof prism binocular, the EDF is amazingly compact and light-weight for its specification and ruggedness. Its telescopic rubber eye-cups fold down and are fully compatible with spectacle use. The serial number starts with 'G', indicating 1987 as year of production. This is the version of EDF with illumination (there was also a version without, see here). It features a lever right to the right hand side ocular to switch on/off the reticle illumination, and the symbol for radioactivity. The light source is a small hollow and transparent capsule, filled with radioactive tritium gas and inner walls coated with a tin sulfide layer. The tritium is decaying, emitting electrons which then excite the tin sulfide to emit photons, which finally illuminate the reticle. The EDF was constructed so that the illumination could be removed or installed during maintenance work, i.e. both versions were interchangeable. When the NVA was absorbed into the West German Bundeswehr, the stock of binoculars was taken over, but the illumination was removed since the tritium source did not adhere to the strict West German environmental protection laws. This binocular is therefore much less frequently found on the surplus market and easily sells for 400 Euro. A civilian version is still produced by Docter Optics (see links below) and sells for 700 Euro.
由于利用屋脊棱镜，相对于其性能和坚固，EDF有令人惊讶的紧凑性和轻便性。它的伸缩橡胶眼罩向下折后可以戴眼镜使用。它的序列号中以'G'开头指明是1987年生产的。本镜是带有内部照明（有不带的版本，见这里）右目镜右边有拨杆，是分化板照明和放射源标记开关。光源是一个小型空心透明容器，塞满了放射性气体氚，内壁涂上硫化亚锡，氚发生蜕变，放出电子，激发硫化亚锡发光，最后照亮分化板。EDF的照明系统在维修时能被移除和重新安装，即两个版本可以互换。当NVA并入西德边防军，库存的镜子被接管，因氚不符合西德的环境保护法，照明系统被移除。因此这个镜子是剩货市场上不常见的，能很容易卖到400欧元。民用版EDF一直在Docter Optics生产（见下面链接），售价700欧元。


Fig. 3: The Polish PZO 7x45
3号：波兰 PZO 7x45

There is very little information available about this binocular. According to Seeger ('Military Binoculars and Telescopes for Land, Air and Sea Service'), the manufacturer PZO (Polskie Zaklady Optyczne) is located close to Warsaw and was during German occupation producing optical instruments for the Wehrmacht. The PZO 7x45 is presently employed in the Polish army and may be still in production, (see the link at the bottom of this page), but I could not detect any serial number on this device. On the left hand prism housing there is a lever to swing in/out the infrared detector plate. There exist also versions of the PZO without infrared detector and reticle. The specification 7x45 is unusual - it closes the gap between the low light 7x40 binoculars and the true night glasses with 7x50. This device comes with grey colored ocular filters which are stored inside the ocular cover. The rubber eye cups are contoured and, like with the IOR, fold down to expose a metallic ring which then might scratch eye-glasses. This binocular is occasionally found on Ebay and sells for 200-250 Euro in good condition.
几乎得不到关于这个望远镜的信息，根据Seeger的“陆海空军的望远镜”，PZO(Polskie Zaklady Optyczne)制造厂在华沙附近，德国占领期间为德国纳粹边防军生产光学设备。PZO 7x45波兰军队的当前装备，或许现在仍在生产，（参看下面链接），但我在这镜子上没找到任何序列号数字，在左边棱镜室上有拨干能旋出/入红外感光板，也有没有红外观测功能和刻度板的PZO版本。7x45这规格并不常见，处于低亮度的7x40和夜用的7x50之间。它在目镜盖内存有灰色滤镜。波状橡胶目镜罩和IOR的一样，当翻折后露出的金属圈能刮伤眼镜。在Ebay上偶尔能见到这镜子，好品相的能卖到200-250欧元。

The following table summarizes some of the specifications of the contenders.
下表中是被评测对象的各项指标


Optical performance光学性能

Angle of view: These are low light binoculars and one should not expect excessive wide fields of view. Closest to 'wide angle' comes the IOR with 60 degs. apparent angle, which is sufficient to avoid the tunnel-view of its contenders. In fact, with 53 degs. the EDF does not show much. Even narrower is the view through the PZO: The (roughly) 50 degs. is a typical feature of night glasses, and forms the poor standard for most of the 7x50 binoculars.
视角：这些都是低亮度望远镜，不能期望有极宽广的视角，最接近“广角”的当属有60度表现视场IOR，远离了只有管窥视野的其它两款。实际上，只有53度视角的EDF不可能显示太多，通过PZO看的视野更狭窄：大约50度。是典型的夜用镜特征，与大部分7x50望远镜相比，PZO的夜视水平是最低的。

Image sharpness: The EDF delivers the most convincing performance. From the center to about 80% (radial) to the edge, stars look point-like, and close to the edge the distortions are low to moderate. Its center sharpness is high as is the IOR's and PZO's. The PZO shows some distortions from about 70% onwards, with still a moderate level of aberrations close to the edge. The IOR is razor sharp within 60% of the field, then, toward the edge, degradeing, first slowly and then, close to the edge, more rapidly, were the image quality becomes poor. This is not unusual for a binocular of this angle of field. In fact, the overall image sharpness of the IOR is comparable to the NVA DF 7x40.
图像清晰度：EDF有最有说服力的表现，从中心到离边缘80%（半径）处，看星星还是点状，接近边缘处的变形低至中等。它中心部位的分辨率与IOR及PZO的一样高。PZO从70%处开始扭曲，到边缘处仍旧是中等程度的畸变。IOR在60%内是如剃刀削般轮廓分明，再移向边缘就降低等级了，开始是慢慢的，靠近边缘时急剧下降，图像质量变很差。对于类似视野的望远镜这并不奇怪。实际上，IOR总体上图像清晰度与NVA DF 7x40很类似。

Image color: The EDF has got a very strong yellow tint. The origin of this color can be traced down to the negative lens of the objective and the first ocular lens. Both of them are made of SF3R, a special radiation resistant flint glass (here I have to correct my statement made in another review: The origin of the yellow color is, at least in the EDF, a radiation resistant glass). The background information can be found on Albrecht Koehler's page (German language): Some flint glasses have got the property to turn black when exposed to radiation. Fortunately, there exist radiation resistant counterparts with identical principal optical characteristics, but not always with neutral color. In this particular example, extended field tests during the construction of the EDF led to the conclusion that the yellow color had positive side effects: Under hazy conditions, the image contrast was improved, and under very bright light conditions, e.g. a sunny day over snow or at sea, the eye strain was reduced and the hazardous UV contribution of the light was removed. That's exactly the reason why some professional binoculars come with yellow filters to be attached to the oculars. The IOR and PZO provide almost neutral image colors. Only a straight comparison reveals that the IOR has a slight yellowish tint and the PZO's image is slightly brownish. None of these binoculars gives a completely neutral color rendition. It is of relevance that the image brightness of the IOR is superior to the PZO and the EDF. Only close to the edge a loss of brightness (vignetting) is visible in the IOR.
图像颜色：EDF强烈偏黄。这黄色的来源能追踪到物镜的负透镜和第一块目镜，这两个都是SF3R做的，一种特殊的能抗辐射的含铅玻璃（这里我纠正另一个评测中的观点：黄色的来源，至少在EDF中，是抗辐射玻璃）。背景知识可以在Albrecht Koehler's page找到（德语）：当暴露在辐射中，一些含铅玻璃有变黑的特性。幸运的是，有同样光学规格并且抗辐射的同档次玻璃，但不是无色的。在这个特别的例子中，研制EDF期间，扩展的实地测试得出一个结论，黄色起了积极作用：在朦胧的情况下，图像的对比度加强了，在非常亮的情况下，如雪地上强烈阳光下或者在海上，减轻了眼镜疲劳，光线中对眼镜有害的紫外线被阻挡。这也解释了为什么有些专业望远镜要附带接在目镜上的黄色滤光片。IOR和PZO提供了几乎真实颜色，只有直接对比能显露IOR图像是轻微黄色，PZO图像是轻微褐色。其中没有哪款能提供真实的色彩还原。中肯的讲，IOR的图像亮度优于PZO和EDF。IOR的靠近边缘的亮度损失（渐晕，逐渐模糊）是明显的。

Rectilinear distortion: Most binoculars employ a slight pincushion distortion, which is intentionally installed to provide a smooth panning. Without this distortion, the still image looks perfect, but when panning, the same seems to roll over a convex surface, ("globe effect"), as is the case with the Russian BPO 7x30. The IOR and PZO show a slight pincushion distortion which compensates for this rolling ball and leads to a smooth panning. I have noticed that in case of the EDF the amount of pincushion distortion may be a little too large: It over-corrects, i.e. when panning, the image appears to show a concave curvature so that it seems to scroll over the inner surface of a globe. But the quantity of this effect is not yet on a disturbing level.
直线扭曲：大部分望远镜表现有轻微的枕形畸变，这是有意如此，为的是能得到平滑的视场盘。如果没有这扭曲，看图像依然完美，但当移动时，图像似乎在沿弧形滚动(滚球效应)。俄罗斯的全七就有这现象。IOR和PZO轻微的枕形畸变，就是为了减缓滚球，得到平滑视场。我注意到EDF的枕形畸变的程度可能有点过大：矫枉过正，就是说，当移动时，图像显示了凹弯曲，看起来犹如看图像扫过一个球的内壁，但这个影响没有高到令人烦恼的程度。

Stray light: Under difficult viewing conditions, especially a twilight, light from sources outside the field can enter the objective lenses through a large angle to illuminate the tube walls and is, partially, scattered into the optical path. It then enters the observer's eyes as a diffuse illumination of the image. A suppression of this stray light is mandatory to preserve a maximum contrast under difficult viewing conditions, and here all three binoculars are on a professional level. I was unable to provoke any situation where such effects could significantly affect the image quality. If I had to name the most characteristic optical feature of these East block binoculars, then it is probably the excellent control of stray light. And here one comment seems adequate: These glasses are often smiled at, as being bulky and heavy like a tank. But one has to consider the following: A successful stray light suppression first of all requires one thing - space. The tubes and prism housings have to be properly dimensioned to leave space for internal baffles and other constructions to shield the prisms. Consequently, these instruments are somewhat larger than usual, but they are doing well under conditions where others are badly loosing contrast.
漫射光：在困难观测条件下，特别是黄昏黎明，视场外的光线能以大角度穿过物镜，照亮了镜筒内壁，部分混入了主光路，进入观测者眼镜，使得图像弥漫着杂光。抑制漫射光的方法是困难观测情况下尽量维持最大对比度，这里三款镜子这方面都处于高水平，我无法创造任何能明显影响像质的环境。如果我必须认定这些东方阵营望远镜的最典型的特征，那大概就是优秀的控制漫射光的能力。这里的一个结论应该恰当：如同坦克般庞大笨重，这些镜子经常被嘲笑。但是必须考虑到：如果要成功制止漫射光首先需要一个条件——空间，镜体和棱镜室必须有妥善的尺寸以容纳阻挡隔板和棱镜护板。因此，这些镜子比一般镜子稍微大一些，但当处于能使其它镜子的严重丧失对比度的情况下，依然工作的很好。

Ghost images: If, at night, a bright object (street lantern, moon) is positioned into the field, reflections on the air-to-glass surfaces take place, which can lead to secondary 'ghost' images of the light source. The EDF is performing best. There is no ghosting through the left tube, and through the right one, the reflections on the reticle remain on a very low level. Closely behind are the IOR and PZO. The IOR displays a diffuse and very dim ghost image through the left tube, the PZO a small localized and slightly brighter one. Through the right tube, another reflection of low intensity takes place on the reticle in both of the glasses. Altogether the ghost image suppression is well done in all three of the competitors.
鬼影：如果在夜晚，一个明亮物体（路灯，月亮）进入了视野，镜片表面发生反射，能产生明亮物体的二次“鬼魂”般图像。EDF表现最好，左镜筒没有鬼影，右镜筒因为刻度板的反射，鬼影处于很低水平。紧跟后面的是IOR和PZO。IOR的左镜筒有因漫射光而产生的非常模糊不清的鬼影，PZO左镜筒有一个小的有点亮的鬼影。两款镜子的右镜筒都有刻度板的微弱反光。总之，三款镜子的鬼影抑制的都很好。

Low light performance: Here the IOR presents a most convincing performance. Not only at daylight, also after sunset its image appears to be the brightest one. With decreasing amount of residual light, the PZO is catching up: Once the observer's eye-pupils diameter exceeds 5.7 mm, the PZO can take profit of its superior exit-pupil diameter. However, the low light performance of the PZO could never surpass the IOR's. Obviously, the light-transmission rate must be significantly higher in case of the IOR. The coating of this binocular, made in 2000, must be state of the art. Another factor may be a physiological one: The human's eye is optimized for daylight use. After sunset, the spectrum of the residual light is shifting toward the short wavelength (blue) side. A slight yellow tint as present in the IOR may compensate for this effect, i.e. shifting the image color back to what the eye is optimized for. The EDF, with fully multi-coated optics, is also performing well. At twilight it is on the same level as the PZO, but at very low light it is falling a little behind. Here one has to consider the fact that its strong yellow color is reducing the transmission, more so than the just slight yellow tint of the IOR.
低照明表现：在这里IOR表现的最有说服力。不仅在白天，即使在日落后它的图像表现的也最亮。随着亮度降低，PZO就赶上来了：如果一个观测者的瞳孔直径超过5.7mm，PZO就能从它的出瞳直径得到利益。不过，PZO在低照明下的表现永远超不过IOR。这款2000年生产的IOR，肯定用了最高技术。另一个影响因素是生理上的：人类的眼镜是为白天使用优化过的，日落后，残留光线的光谱移向短波长那边（蓝色），IOR的轻微偏黄能补偿这种影响。就是说，将图像颜色移回眼镜最敏感的区域。拥有多层镀膜的EDF，也表现很好。黄昏时的表现同PZO处于一个水平，但在非常暗的照明下比PZO稍微差。这里必须考虑一个事实，就是它的强偏黄色减少了透光率，程度超过了轻微偏黄的IOR。


Mechanical construction 机械结构
There is little left to complain about. All three binoculars are of extremely solid, tank-like construction. They are sealed against water and dust, the rubber armor forms a protection against mechanical impact. Mechanical movements are stiff and smooth. None of the contenders exposes any weak point here. The lubricant has been tested to be operational at low temperatures like -30 degs. Celsius. For spectacle-wearer, the EDF is best suited. Although the eye relief is long enough in case of the IOR and PZO, it is of limited use because when folding down the eye cups a metallic ring is exposed which could do harm to the eye-glasses.
几乎没有留下抱怨，所有这三款镜子都有极其坚固，像坦克般的结构。他们都密封防水防尘，外包橡胶提供了机械碰撞的保护。机械运动生硬平滑。没有哪款暴露弱点。润滑油经受了零下30摄氏度的测试，能正常使用。对于戴眼镜使用者，EDF是最合适的。虽然IOR和PZO的出瞳距离足够，但还是不适合戴眼镜使用，因为当翻下眼罩后，露出的金属圈，能划伤眼镜片。

Summary 总结
The following table is supposed to summarize the above observations. The best performing binocular gets three points, the following contenders two and one, respectively. In case several binoculars are ranking equally, their scores are averaged.
下表是上述各性能的总结。表现最好的镜子得3分，后面的分别得2和1。如果几个镜子的排名同样，它们的分数取平均。

The 'final score' is the sum of the individual scores and is intended to serve as an orientation only. Generally, it would be an over-simplification of the matter to just look which binocular has got the highest score, because it would obscure the individual features of the devices which could differ quite a lot among each other.
Final score是各项得分的和，仅供参考。一般的，只是看某款镜子得到最高分，是将问题过于简单化了，因为这将掩盖镜子的各独立特性，而各镜子的这些特性相差非常大。

The IOR-SA 7x40 is, though with a small margin, the winner of this competition. It displays the widest and brightest image among the three tested devices. Its low light performance is especially impressive. The fact that the image quality is poor close to the edge appears to be of little relevance. Personally, I prefer a wide field of view with some problems at the edge over a narrow field of view with perfect image. Some comments regarding the East German DF 7x40 are useful: The IOR has got similar features, identical specification and field of view. A difference emerges with the fact that the IOR shows some vignetting, which is not there (or much less so) in the DF. The reason is that the DF employs larger prisms, which enable it to fully illuminate the 60 degs. field of view. On the down side, the DF is more bulky and heavy. Here one has the choice: A bulky device with full illumination, or a more compact one with some vignetting. Apart from that, the IOR has got the advantage because of its state of the art lens-surface coating.
虽然分数差别很小，IOR-SA 7x40得到了冠军。三款镜子中，它提供了宽阔明亮的图像，低照明下的表现给人印象尤其深。事实上在边缘处的低劣像质似乎无关紧要。就个人而言，我喜欢边缘有问题的宽视场，而不喜欢图像完美的窄视场。某些东德DF 7x40的思维被利用上了：IOR有类似特性，同样性能和视场。不同之处是IOR表现某些渐晕，DF没这现象（或者非常轻微），原因是DF拥有更大的棱镜，能完全照亮60度视场，另一方面，DF更大更重。现在就可以选择：一个拥有完全照明的巨大设备，或者一个更紧凑的有些渐晕的设备。另外，IOR因为镜片表面的现代镀膜工艺而更优越。

The East German NVA EDF 7x40 is since long known to be an excellent binocular. Its prime advantage is its compact size and low weight. When it comes to performance-per-kg, the EDF is ahead of the competition. Disturbing under most seeing conditions is its yellow color. It should be mentioned that a civilian version of the EDF is still in production by Docter Optics, without infrared detector, reticle illumination and without radiation resistant lenses. These binoculars are supposed to have a neutral color rendition, which I think is an advantage. Please note that such a device would have ended up on top of this competition, since it had gained points in both subjects, color rendition and, likely, also in low light performance, since the coating has certainly improved since 1987. With its excellent ghost image and stray light suppression, the EDF is still a good choice for professional applications under any weather conditions.
东德NVA EDF 7x40是久负盛名的优秀望远镜。它的棱镜优越性是紧凑的尺寸和低重量。如果比较性能重量比，EDF排在最前。大部分观测情况下的黄色是令人烦恼的。应被提及的是民用版EDF现在仍在Docter Optics生产，没有红外探测，分化照明和抗辐射镜片，猜测这样的镜子应该表现自然色。我认为这是优点，请注意这样的镜子将在本测试中以最终获得最高分，因为将在两方面得分，颜色表现，还有在透光率方面，毕竟1987年后镀膜技术显著提高了，加上优秀的防鬼影和漫射光表现，EDF是任何天气情况下专业应用的好选择。

The Polish PZO 7x45 is hardly known so far. In contrast to other binoculars made in the Warsaw Pact states, this one comes without the characteristic yellow tint, but with its brownish image its also not completely neutral in color. Similar to the competitors, its ghost image and stray light suppression is on top level. A disadvantage is the narrow field of view. Also, the PZO can't take full advantage of its superior objective lens size: Surprisingly, it is beaten by the IOR in their low light performance. Unfortunately I have no clue about the year of production of this item. It appears that the transmission rate is not state of the art. Apparently, this binocular is still in production, and the current version might be delivered with an improved coating.
迄今为止波兰的PZO 7x45仍不为人知。与其它华沙条约组织成员国生产的镜子相比，它没有偏黄特征，但它的偏褐色仍不是完全自然色。类似的，它的鬼影和漫射光控制也处于高水平。缺点是窄视场。同样，PZO没有充分发挥大物镜的优势：令人惊讶的，在低照明下的表现它被IOR打败。遗憾的是我不能确定这镜子的生产年份。表现上透光率也不高。显然这镜子还在生产，可能当前产品已经有了改良的镀膜。

简单看了下，对“IOR和PZO提供了几乎真实颜色”不敢苟同。
IOR也是严重偏黄的镜子，PZO应该是偏点黄（青）色，个人感觉偏色程度EDF》=IOR》PZO。
PZO是只比较平庸的镜子，这与猴哥的看法有些类似。

说实话，翻译完我都想在后面加上一句“德国人的眼睛是否看啥都不黄”。
不过后来一想，他的样品是2000年生产的，或许不偏黄了。

玩军镜的DX，EDF可以搞一只。非常有特色的镜子，镀膜也很养眼

阿鼎KGB

我原先也比较过IOR和全7
IOR的黄，也很厉害。视场也比较宽。（这么黄的镜子还配了黄色滤镜）不过全7的黄色更‘鲜艳’一些，所以我感觉更讨巧。
除了边缘像质和畸变外，几乎其他方面都胜过全7。体积重量也近似。
而且，观红屏的成像细腻程度要明显好于国产62观红。
