SWAROBALANCE 主動式防手震技術：AT Balance 18-45x 65mm 深度評測 （圖/文 生態協會）
Swarovski 新品 AT Balance 18-45x 65mm（下稱 AT Balance）是將頂級光學及極致防震揉合在一起的革新產品，亦是 Swarovski 繼 ATC 17-40 x 56mm（下稱 ATC）之後再一次掀動市場的產品。
讓我們來比較一下 AT Balance 及 ATC 兩支單筒望遠鏡。ATC 是 Swarovski 產品線中最為輕巧的 45 度單筒望遠鏡，重量只有 970 克，比 AT Balance（1,470 克）輕了整整 500 克，而且長度更短，更容易攜帶（早前已經過評測文章）。然而 AT Balance 雖然相對較重，但它的內建防手震技術是無可取代的優勢。這讓大家在手持使用，甚至在高倍率下，也能獲得極穩定的畫面，無需必要使用三腳架。
AT Balance 使用可充電的 RB-S 鋰離子電池（1860 mAh），目鏡下有一個防手震功能的開關按鈕，手持使用時只需要按壓開關約一秒鐘便可以啓動防震功能，本來搖晃的影像亦瞬即變得穩定。鏡身亦設有智慧省電功能：靜置 5 分鐘後會自動進入低功耗待機模式，這時只要輕微傾斜或移動機身，就能瞬間喚醒防震功能繼續觀察。
Swarovski 官方數據表示 RB-S 鋰離子電池續航數據為約 12 小時（常溫下），實際野外測試時（室外氣溫攝氏 27-32 度）防手震功能由清晨到黃昏全開了一整天（間歇性進入待機模式），電量仍然可以繼續使用。低溫環境會縮短續航力。官方數據顯示在 -10°C 下，RB-S 續航約為 4 小時。若有長時間低溫手持觀察需求，建議攜帶備用電池。
考慮到一支較為穩固的三腳架連雲台重量動輒超過 1,800 克，在實際操作使用時的整體重量（ATC ＋三腳架連雲台 vs 手持 AT Balance），AT Balance 仍然稍有優勢。
AT Balance 在口徑（65mm vs 56mm）和最高倍率（45x vs. 40x）上都較 ATC 略勝一籌，這表示它在低光極限條件下的解析力與集光力理論上會更好，而兩者的最近對焦距離同為 3.4 米，在近距離觀察的能力上不分軒輊。
用家們亦會將 Swarovski ATX 25-60 x 65mm（下稱 ATX 65）和 AT Balance 作比較。官方數字 ATX 65 重量為 1,585 克，而 AT Balance 重量為 1,470 克，較前者輕了約 115 克。倍數方面，ATX 65 為 25-60 X，而 AT Balance 的倍數為 18-45X。ATX 65 以 25X 作為起點，視角約為 2.37°，而 AT Balance 在最低倍率時（18X）視角約為 3.16°。千萬別小看這不足 0.8° 的差別，AT Balance 在 18X 明顯比 ATX 65 在 25X 時提供了更寬廣的視野（約 1/3 倍寬）。這也意味著 AT Balance 在低倍率掃描時，能更輕鬆地捕捉與鎖定目標（例如在枝條之間的林鳥、飛行中的猛禽、夜空中的星團星雲等）。在同樣 65mm 的物鏡口徑之下，AT Balance 的 18X 亦可以提供比 25X 更為明亮的影像。
ATX 65 的透光率約 86%，25X 時出瞳直徑範圍為 2.6mm，而 AT Balance 的透光率稍高，約 88%，18X 時出瞳直徑範圍為 3.4mm。實際在野外使用時，在同一倍數之下肉眼其實難以分辨兩者相差僅 2% 的透光率，但低倍的 AT Balance 的 18X 在各方面的實用性都比 ATX 的 25X 更高。
如果要比較 AT Balance 的最高倍數 45X 和 ATX 65 的 60X，數字上 ATX 65 在適合需要極致細節的觀察例如遠方的水鳥的腳旗編號或月球上的隕石坑等會稍具優勢，但用家亦要考慮較高倍數時入光量變少、器材微震及大氣晃動等對於觀察的影響。AT Balance 的 45X 雖然放大倍數上限較低，但它的設計核心是手持使用的方便性，透過防手震技術補償了高倍率下容易抖動的問題，讓用家能夠快速獲得清晰視野。長時間使用時，用家亦可以選擇把 AT Balance 裝上三腳架使用，節省體力及電池消耗。AT Balance 的低倍 18X 很適合在樹林之中使用，高倍 45X 亦很足夠辨識約一公裡外的水鳥類（鳥功方面則要大家自行修煉了）。如果以觀鳥作為主要用途，AT Balance 的 18-45X 已足以應付大部份場景。
除了倍數上的比較，另一項要注意的地方是兩支單筒望遠鏡的最近對焦距離。ATX 65 其中一個最為用家津津樂道的是其最近對焦距離：2.1 米（25X），甚至比不少雙筒望遠鏡還要短。相比 AT Balance 的 3.4 米（18X），ATX 65 可以提供更方便的近距離觀察體驗。實際野外操作時，除非是特別要觀察昆蟲等近距離及靜止不動的主體，以觀鳥觀星作為主要用途，AT Balance 的 3.4 米亦相當足夠。
ATX 65 使用 ATX 系列的 45 度單筒望遠鏡模組物鏡，提供了可供旋轉的中央三腳架接環，只需要轉動鏡筒便可以調整目鏡的高度讓不同用家使用。而主攻手持使用的 AT Balance 則沒有配置可以轉動鏡身的三腳架接環，如果裝在三腳架上讓多人輪流使用時（例如團隊中要照顧不同高度的大小朋友），建議先將三腳架調整到適合小朋友的高度，或使用有「中軸」可以方便調校高度的三腳架，以免要經常調校三腳架腳管長度而錯失觀察機會。
對於使用三腳架的用家來說，AT Balance 有一項十分實用的設計，其底部的三腳架接口兩旁各有一個小孔，配合隨包裝盒附送，擁有兩個突出點的快拆板（底部的「AS」字樣表示適合 Arca Swiss 規格），使用時可以防止鏡身和快拆板之間的轉動，避免鏡身意外松脫掉落。
如果希望將單筒望遠鏡作為超長焦鏡頭使用的用家，使用 ATX 目鏡模組的 ATX 65 在拍攝工具方面會有更多的選擇。ATX 目鏡模組可以配合 TLS APO 及其相應接環，接上各品牌的單反、無反、微單等使用，發揮相機的高像素、高 ISO 及機身防震功能。ATX 65 亦可以透過 Swarovski 自家的 VPA 2（Variable Phone Adaptor）＋CA-S（將 VPA 2 扣上單筒目鏡膠圈的零件），將手機的鏡頭準確對接望遠鏡的光軸，提供高效的拍攝效果。而採用了物鏡目鏡一體化以減輕重量的 ATC及AT Balance（以及稍後將會討論的ST Balance） 則只可以安裝 VPA 2 ＋CA-S，接上手機作為拍攝之用。如何選擇，主要看用家們的拍攝習慣。
ATX 系列的特點是採用模組式結構，用家可以使用同一個目鏡接上不同口徑物鏡（例如 65mm、85mm、95mm 及 115mm），擴展性較大。ATC、AT Balance 及 ST Balance 採用一體化設計，進一步減輕重量及體積。售價方面，官方標價 ATX 26-60 x 65mm 約為 USD 4,348，ATC 17-40x 56mm 約為 USD 2,999，AT Balance 18-45x 65mm 約為 USD 3,999。
即使長焦鏡頭大行其道，光學觀察的樂趣仍然絲毫不減。用家們都知道沒有任何一支望遠鏡可以應付所有場景和需要。Swarovski 出品的望遠鏡在光學表現上無容置疑，選擇時用家主要考慮的是操作性、便攜性和價錢等。對於喜歡進行各項自然生態及天文夜空觀察的用家，考慮到倍數及視角、重量和體積、快速手持實用性及價格等，AT Balance 應該是三者之中最平衡的選擇。

SWAROBALANCE Active Image Stabilization Technology: AT Balance 18-45x 65mm In-Depth Review (Photos/Text: Eco Institute)
The new Swarovski AT Balance 18-45x 65mm (hereinafter referred to as AT Balance) is an innovative product that combines top-tier optics with ultimate stabilization, and is another market-shaking product from Swarovski following the ATC 17-40 x 56mm (hereinafter referred to as ATC).
Let us compare the AT Balance and ATC monoculars. The ATC is the lightest 45-degree monocular in Swarovski's product line, weighing only 970 grams—a full 500 grams lighter than the AT Balance (1,470 grams)—and is shorter in length, making it easier to carry (a review article has been published previously). However, although the AT Balance is relatively heavier, its built-in image stabilization technology is an irreplaceable advantage. This allows users to obtain an extremely stable image even when using it handheld, and even at high magnification, without necessarily needing a tripod.
The AT Balance uses a rechargeable RB-S lithium-ion battery (1860 mAh). There is a stabilization function switch button beneath the eyepiece. When using it handheld, simply pressing the switch for about one second activates the stabilization function, and the originally shaky image instantly becomes stable. The body also features a smart power-saving function: after being left still for 5 minutes, it automatically enters a low-power standby mode. At this point, a slight tilt or movement of the body instantly wakes the stabilization function to continue observation.
Swarovski's official data states that the RB-S lithium-ion battery has a runtime of approximately 12 hours (at room temperature). In actual field testing (outdoor temperatures of 27-32°C), the stabilization function was left on all day from morning to dusk (intermittently entering standby mode), and the battery still had charge to continue use. Low-temperature environments shorten battery life. Official data shows that at -10°C, the RB-S runtime is approximately 4 hours. If there is a need for long periods of low-temperature handheld observation, it is recommended to carry a spare battery.
Considering that a relatively sturdy tripod with head often weighs over 1,800 grams, in actual operational use the overall weight (ATC + tripod with head vs. handheld AT Balance), the AT Balance still has a slight advantage.
The AT Balance is slightly superior to the ATC in both objective diameter (65mm vs. 56mm) and maximum magnification (45x vs. 40x), which means that in low-light extreme conditions its resolving power and light-gathering ability should theoretically be better. Both share the same closest focusing distance of 3.4 meters, so they are evenly matched in close-range observation capability.
Users will also compare the Swarovski ATX 25-60 x 65mm (hereinafter referred to as ATX 65) with the AT Balance. Official figures put the ATX 65 weight at 1,585 grams, while the AT Balance weighs 1,470 grams—about 115 grams lighter than the former. In terms of magnification, the ATX 65 is 25-60X, while the AT Balance is 18-45X. The ATX 65 starts at 25X with an angle of view of about 2.37°, while the AT Balance at its lowest magnification (18X) has an angle of view of about 3.16°. Do not underestimate this difference of less than 0.8°—the AT Balance at 18X clearly provides a wider field of view than the ATX 65 at 25X (about 1/3 wider). This also means that the AT Balance can more easily capture and lock onto targets when scanning at low magnification (for example, forest birds among branches, raptors in flight, star clusters and nebulae in the night sky, etc.). Under the same 65mm objective diameter, the AT Balance's 18X can also provide a brighter image than 25X.
The ATX 65 has a light transmission of about 86%, with an exit pupil diameter of 2.6mm at 25X, while the AT Balance has a slightly higher light transmission of about 88%, with an exit pupil diameter of 3.4mm at 18X. In actual field use, at the same magnification the naked eye can hardly distinguish the mere 2% difference in light transmission between the two, but the low-magnification AT Balance's 18X is more practical than the ATX's 25X in all respects.
If comparing the AT Balance's maximum magnification of 45X with the ATX 65's 60X, numerically the ATX 65 has a slight advantage for observations requiring extreme detail, such as the leg-flag numbers of distant waterbirds or lunar craters. However, users must also consider the effects on observation of reduced light intake at higher magnifications, micro-vibrations of the equipment, and atmospheric turbulence. Although the AT Balance's 45X has a lower maximum magnification, its design core is the convenience of handheld use. Through stabilization technology, it compensates for the problem of easy shaking at high magnification, allowing users to quickly obtain a clear field of view. For extended use, users can also choose to mount the AT Balance on a tripod, saving energy and battery consumption. The AT Balance's low magnification of 18X is very suitable for use in forests, and the high magnification of 45X is sufficient to identify waterbirds about one kilometer away (birding skills, however, are up to you to cultivate). If birdwatching is the main purpose, the AT Balance's 18-45X is sufficient for most scenarios.
Besides the magnification comparison, another point to note is the closest focusing distance of the two monoculars. One of the ATX 65's most celebrated features among users is its closest focusing distance: 2.1 meters (at 25X), even shorter than many binoculars. Compared with the AT Balance's 3.4 meters (at 18X), the ATX 65 can provide a more convenient close-range observation experience. In actual field operation, unless specifically observing insects or other close-range and stationary subjects, for birdwatching and stargazing as the main purposes, the AT Balance's 3.4 meters is quite sufficient.
The ATX 65 uses the ATX series 45-degree monocular module objective, offering a rotatable central tripod collar—simply rotating the barrel adjusts the eyepiece height for different users. The AT Balance, designed primarily for handheld use, does not have a rotatable tripod collar. If mounted on a tripod for multiple people to use in turn (for example, when a team needs to accommodate adults and children of different heights), it is recommended to first adjust the tripod to a height suitable for children, or use a tripod with a "center column" that allows easy height adjustment, to avoid having to frequently adjust the tripod leg lengths and miss observation opportunities.
For users who use a tripod, the AT Balance has a very practical design: on either side of the tripod socket at the bottom, there is a small hole. Together with the quick-release plate included in the box, which has two protruding points (the "AS" marking on the bottom indicates Arca Swiss compatibility), this prevents rotation between the body and the quick-release plate when in use, avoiding the body accidentally loosening and falling off.
For users who wish to use the monocular as a super-telephoto lens, the ATX 65, which uses the ATX eyepiece module, offers more choices in terms of photographic tools. The ATX eyepiece module can be paired with the TLS APO and its corresponding adapters to connect to DSLR, mirrorless, and compact system cameras of various brands, leveraging the camera's high pixel count, high ISO, and in-body stabilization. The ATX 65 can also use Swarovski's own VPA 2 (Variable Phone Adaptor) + CA-S (the part that attaches the VPA 2 to the monocular eyepiece rubber ring) to accurately align the phone's lens with the telescope's optical axis, providing efficient shooting results. The ATC and AT Balance (and ST Balance which will be discussed later), which use an integrated objective-eyepiece design to reduce weight, can only mount the VPA 2 + CA-S to connect a phone for photography. The choice mainly depends on the user's shooting habits.
The ATX series is characterized by its modular structure: users can use the same eyepiece with different objective diameters (e.g., 65mm, 85mm, 95mm, and 115mm), offering greater expandability. The ATC, AT Balance, and ST Balance use an integrated design, further reducing weight and volume. In terms of pricing, the official list prices are approximately USD 4,348 for the ATX 26-60 x 65mm, approximately USD 2,999 for the ATC 17-40x 56mm, and approximately USD 3,999 for the AT Balance 18-45x 65mm.
Even though telephoto lenses are all the rage, the joy of optical observation remains undiminished. Users know that no single telescope can handle all scenarios and needs. Swarovski's telescopes are beyond doubt in optical performance; when choosing, users mainly consider operability, portability, and price. For users who enjoy various nature and astronomy night-sky observations, considering magnification and field of view, weight and volume, quick handheld practicality, and price, the AT Balance should be the most balanced choice among the three.
