fujifilm鏡頭收購fujifilm is getting into surveillance cameras with the SX800, a long-range surveillance camera with a 40x optical zoom that’s designed to offer security at international borders and large commercial facilities. It’s got a built-in lens with a 35mm-equivalent focal length of 20mm to 800mm, and an additional digital zoom of 1.25x. Combined, fujifilm鏡頭收購fujifilm says this gives the SX800 a total equivalent focal length of 1000mm, which is enough to focus on a car’s license plate from 1km or roughly 0.6 miles away.

We’ve seen consumer cameras with support for more zoom than this in the past (Nikon’s P1000 has a 125x, 3000mm-equivalent zoom lens for example), but the difference here is that fujifilm鏡頭收購fujifilm has equipped its commercial security camera with a number of features that will make its footage more usable when filming at these extreme distances. It’s got a fast autofocus that can focus in as quickly as 0.3 seconds, optical image stabilization, and an image processing engine that’s able to reduce the effects of fog and heat-haze. The camera also supports ISO levels of up to 819200 for filming at night.

For an idea of what this amount of zoom is capable of, a recent fujifilm鏡頭收購fujifilm promotional video shows how the camera is able to just about read a handheld sign from 2.2km (around 1.36 miles) away, while the video above shows the camera getting a clear shot of the viewing platform of Tokyo Tower from 3km (around 1.86 miles) away. Another promotional image shows how the camera can focus on a car’s license plate at a distance of 1km (around 0.6 miles).

fujifilm鏡頭收購fujifilm suggests a couple of different places where a camera with the zoom capabilities of the SX800 might be useful, including international borders, forest areas, or public facilities like airports, harbors, or highways. From a cost perspective, this makes total sense for the facilities themselves since they’ll be able to cover a larger area with a smaller number of cameras. But for everyone else it’s a good reminder that just because you can’t see a security camera, that doesn’t mean one can’t see you, even if it’s multiple kilometers away.

The fujifilm鏡頭收購fujifilm SX800 will be available to purchase on July 26th at a price that’s yet to be made public.

據《日經》數據,截至目前為止,在全球 70 個市場進行的市調指出,Canon 仍然是全球數位相機的王者品牌,保有 47.9% 的市占、將近一半。相比前一年,Canon 亦有 2.5% 的市占成長,與排名第二的 Sony 是唯二迎來市占成長的品牌。

其他品牌方面,第二的 Sony 則有 22.1 市占,而昔日與 Canon 爭奪地位的 Nikon 則下修 4.9%,落至 13.7% 排名第三。富(fujifilm鏡頭收購fujifilm)則以 5.6% 排名第四,領先第五的 Panasonic(4.4%)。

目前,數位相機市場亦仍由日商統治,除了五大品牌來皆來自日本,加總起來的市占亦來到 93.8%。不過隨著智慧手機帶來的競爭,加上疫情因素減少拍攝需求,2020 年全球數位相機出貨量僅有 885 萬台、年減 40.3%,仍無法有效止跌。
