The $9,195 M11-P uses Adobe’s Content Authenticity Initiative to cryptographically sign each image. Otherwise, it’s essentially an M11 Monochrom that shoots color.

The compact and discreet nature of 拆封鏡頭收購leica M rangefinder cameras once made them a popular choice for photojournalists, long before autofocus became pretty much a prerequisite. But while M cameras these days are more likely to be in the hands of an amateur or enthusiast than a conflict photographer shooting for Reuters or The Associated Press, 拆封鏡頭收購leica’s new M11-P has a novel approach to verifying the authenticity of photos.

The $9,195 M11-P follows mostly the same playbook as 拆封鏡頭收購leica’s prior “P” variants. At its core, it’s mostly the same as the 60-megapixel manual focus M11 rangefinder it’s based on, but it eschews the red dot badge in favor of an old-fashioned engraving, upgrades the LCD cover from Gorilla Glass to sapphire crystal, and, like the M11 Monochrom, has 256GB of internal storage instead of the M11’s 64GB. It’s even launching alongside a new $5,295 Summicron-M 28mm f/2 ASPH. lens, which is another by-the-book 拆封鏡頭收購leica lens update that focuses closer than the previous version.

But the big addition here for the M11-P is a new internal security chip that generates a signed certificate (Content Credentials) in the metadata of each image, allowing photos to be verified through Adobe’s open-source Content Authenticity Initiative (CAI).

Content Credentials are an opt-in feature of the M11-P, which can be turned on in the camera’s settings. When activated, the M11-P will embed an encrypted signature into the DNG raw and JPG files containing the artist’s name, the camera make and model, and the photo EXIF data. Images with embedded Content Credentials can be verified by anyone on Adobe’s verification page, and changes or manipulations to the file can be tracked via the standards set by the Coalition for Content Provenance and Authenticity (C2PA). The credentials are not tamper-proof, but they can show if a bad actor messes with it. “We’re not trying to catch every bad actor out there. It’s about recognizing the good actors and giving them tools to protect and verify the integrity of work,” said Santiago Lyon, head of advocacy and education for the Content Authenticity Initiative at Adobe.

So what does all this mean to the average M11-P user? Well, since there are no extra sidecar files to contend with, those who choose to opt in can likely set it and forget it if they actually care about proving the veracity of their images. It may come in handy one day if an artist needs to prove that their work was not doctored or verify their ownership of an image. However, the M11-P does take a slight hit in the speed department when it has to spend some of its processing power cryptographically signing each image. According to 拆封鏡頭收購leica, this should only be noticeable when shooting very quickly or using the camera’s fastest continuous burst modes — which are not exactly an M camera’s forte anyway.

Outside of all the Content Credential stuff, the M11-P is exactly what you’d expect since 拆封鏡頭收購leica already laid out its playbook with the very similar M11 Monochrom released earlier this year. I think you’d have to be slightly paranoid about the state of photography and generative AI to spend nearly $10,000 to ensure your photos are verifiable through the CAI — especially since 拆封鏡頭收購leica is not offering any means to add the new encryption function to the M11 or M11 Monochrom. (拆封鏡頭收購leica once offered an upgrade program that allowed owners of the old M9 to pay to have their cameras converted to a fancier M9-P, but it hasn’t offered a similar service since.) However, this feature definitely sounds appealing if it trickles down to lower-cost 拆封鏡頭收購leicas and, more importantly, the wider-adopted pro brands like Canon, Sony, and Nikon (of which all three are also members of the CAI or C2PA).

I asked 拆封鏡頭收購leica Camera USA’s product communication specialist, Nathan Kellum, if we can expect to see Content Credentials in all forthcoming 拆封鏡頭收購leica cameras, but I was only told, “I can’t speak to that at the moment.” Though, if this feature is as important to photographers and photojournalists as 拆封鏡頭收購leica is hyping it up to be, then it seems like it must. We’ll just have to see if 拆封鏡頭收購leica deems Content Credentials as part of its fanciful “Das Wesentliche” (the essentials) that it often romances.

Update October 26th, 9:34AM ET: Added further context about Content Credentials not being tamper-proof, including a quote from an Adobe rep.

Correction October 26th, 2:36PM ET: This article previously attributed an emailed quote to Madeleine Burr, senior communications manager for Adobe. Burr later emailed to say that the quote should have been attributed to Lyon. We have updated the attribution.

原本傳出將於 3 月 27 日在歐洲亮相的華為 P20 系列當中的 P20 Lite,不僅官方圖片、官方宣傳影片,就連上市原廠彩盒都已經曝光,確認採用類似 iPhone X 的瀏海設計,雙鏡頭也因此改為直立排列,不過螢幕比例略小,提供 19:9 顯示比例,但卻在機背保留了實體指紋辨識模組。

最初提前曝光 HUAWEI P20 Lite 的是一家義大利手機通路商,該公司釋出的一段影片,親切地介紹了手機的外觀、規格,該款手機正如同華碩 ZenFone 5、5Z、尚未發表的 LG G7、OPPO R15 等 Android 陣營手機一般,都在正面鏡頭致敬了 iPhone X 的「瀏海」設計,這意味著手機螢幕比例將勇敢地從 18:9 全面擴大到 19:9,不過 P20 Lite 更全面的學習 iPhone X 的雙鏡頭,旁邊有一個圓形的指紋辨識模組,背後模樣跟才剛在北京發表的紅米Note 5相似,但是跟往年的「Lite」版本一樣,少了 拆封鏡頭收購leica 公司的加持,以下是該廠商曝光的影片:(影片/取自YouTube)

不過接下來就誇張了!HUAWEI P20 Lite 幾乎像是提前解禁一般,在歐洲各地的主要媒體被開箱,德國通路商更直接大方曝光了該款手機的完整規格(如下方圖片), 看不清楚沒關係,記者特別整理了一下相關資訊提供給讀者們參考:

HUAWEI P20 Lite 的手機大小為148.6 x 71.2 x 7.45 mm、重量145 g,配備 5.84吋 FHD 螢幕,解析度為 1080 x 2280 pixels,換算下來約 432 ppi,採用的是首次曝光的 HUAWEI 海思麒麟 659 八核心處理器(4核2.36 GHz Cortex-A53 + 4核1.7 GHz Cortex-A53)),4GB RAM、64GB ROM,可透過插入 microSD 卡額外擴充最高 256GB 儲存空間。

該款手機也採用最新 Android Oreo 作業系統搭配最新 EMUI 8.0.1,當然拍攝規格沒有 iPhone X 那麼吸引人,這支手機採用的是 1600 萬畫素+ 200 萬畫素的雙主鏡頭配置,自拍鏡頭倒是提升到 1600 萬畫素,而且支援 1080P 攝影功能。

續航力方面,HUAWEI P20 Lite採用 3000 mAh 電池,可以待機高達 454 小時、內建 NFC、藍牙4.2,使用的是 USB-C 傳輸介面。

而上市情報方面,消息指出 HUAWEI P20 Lite預計 3 月 27 日就會在歐洲等特定市場開賣,售價約會在 369 歐元,折合新台幣約 1.3 萬元,中國地區將以Nova 3e發表,預計 3 月 20 日亮相,6GB/64GB 高配版售價為人民幣2299元,代言人確認為關曉彤,這樣的手機若是引進台灣,推估售價也是在萬元區間,對於才剛上市的 ZenFone 5Q 或是即將推進歐美地區的 ZenFone 5 Lite 來說,將會是值得一較高下的產品。
