内容总结：

佳能近日正式发布全画幅微单相机EOS R6 III，以7K RAW视频录制与40张/秒高速连拍为核心卖点，强势进军中端全画幅混合相机市场。新品采用全新非堆栈式3250万像素CMOS传感器，画质解析力较前代R6 II的2400万像素显著提升，在性能参数上直接对标索尼A7 IV。

这款相机在拍摄性能上实现多重突破：电子快门支持40张/秒超高速连拍，机械快门连拍达12张/秒，并创新加入0.5秒预拍摄功能，有效避免野生动物与运动摄影中的错过关键瞬间。其搭载第二代全像素双核CMOS AF系统，配合最新AI追踪算法，支持人物、动物、车辆智能识别，更移植了R5 II的“优先注册人物对焦”功能，可在-6EV弱光环境下精准对焦。

视频拍摄能力成为本次升级最大亮点。借助高分辨率传感器，R6 III最高支持7K 60fps RAW Light格式、7K 30fps“全门模式”及4K 120fps高帧率录制，全面内置C-Log2/3伽马曲线。专业视频辅助功能包括波形图监视器、电影级对焦算法，机身防抖性能从8级提升至8.5级。存储方面新增CFexpress卡槽以支持RAW视频录制，同时保留SD UHS-II卡槽。

外观延续经典设计语言，配备三转盘、摇杆及视频/照片快速切换键。3.69百万点电子取景器与索尼A7 IV规格持平，侧翻式触摸屏虽方便vlog拍摄，但未采用倾斜结构，低角度取景时可能遮挡接口。电池续航为390张（CIPA标准）。

同步发布的RF45mm F1.2 STM镜头引发关注，其以346克轻量化设计实现f/1.2大光圈，售价仅470美元，成为高性价比人像镜头选择。

EOS R6 III单机身定价2799美元，搭配RF24-105mm F4 L镜头套机价4049美元。在竞品对比中，其价格高于尼康Z6 III（2500美元），低于支持70张/秒连拍的松下S1 II（3200美元），与索尼A7 IV形成差异化竞争——后者虽具备同规格3300万像素传感器，但缺少RAW视频拍摄能力。

佳能EOS R6 III正式发布，搭载7K RAW视频与40张/秒连拍功能。这款新品采用全新非堆栈式3250万像素传感器，直接对标索尼A7 IV。此次发布标志着佳能正式进军中画幅全画幅混合相机领域——相较EOS R6 II，R6 III在像素精度、连拍速度和视频性能上实现跨越式升级，但定价略显高昂，且未配备同类机型常见的堆栈式或部分堆栈式传感器。

全新3250万像素传感器较R6 II的2400万像素实现显著分辨率提升。配合电子快门可实现40张/秒高速连拍，机械快门与第一帘幕快门模式下仍保持12张/秒性能。创新的预拍摄功能可记录按下快门前0.5秒的20帧画面，确保野生动物与运动摄影中不再错过决定性瞬间。

R6 III延续佳能成熟的双像素对焦系统，并搭载最新AI追踪算法。对焦灵敏度低至-6EV暗光环境，配合新一代Digic X影像处理器（实际表现待实测验证），响应速度更为迅捷。除人/动物/车辆专用追踪模式外，新增的自动主体识别模式可智能切换追踪目标，更从旗舰机型R5 II下放了“注册人物优先级”功能，可锁定预设的特定拍摄对象。

视频性能是本次升级的核心亮点。高分辨率传感器支持7K 60fps RAW Light格式、7K 30fps开放式门模式及4K 120fps高帧率录制，全线标配C-Log2/C-Log3伽马曲线。规格表中长达12页的视频编码格式令人眼花缭乱，涵盖HEVC S/AVC-S/RAW/RAW Light等格式，最高支持7K分辨率。全系列主体识别对焦功能在视频模式下依然可用，佳能传统的视频追焦性能始终在速度与精度方面保持行业标杆水准。

秉承佳能稳健的设计哲学（此前EOS R系列的激进改革并未成功），R6 III延续前代经典机身布局：顶部双调节转盘与背部主控转盘相呼应，配备多功能摇杆、拍摄模式拨杆、模式转盘及丰富自定义按键。侧翻式旋转屏满足vlog拍摄需求，但未采用松下S1 II的多向倾斜结构——可能导致外接麦克风或耳机时遮挡接口，低角度取景灵活性稍逊。368万点电子取景器与索尼A7 IV规格持平，略逊于定位更高的松下Lumix S1 II。存储系统迎来重要升级：新增CFexpress卡槽以支持RAW视频录制与高速连拍，同时保留SD UHS II卡槽。电池与R5 II通用，取景器模式下续航达390张（CIPA标准）。

专业用户青睐的波形图监测功能如约而至，还移植了佳能电影机系统的对焦速度算法，官方宣称可实现“自然专业的焦点过渡”。接口方面配备3.5mm麦克风/耳机插孔、高速USB-C及全尺寸HDMI端口。机身防抖性能从8级提升至8.5级，与松下最新机型持平。

同步发布的RF45mm F1.2 STM镜头令人惊艳：F1.2大光圈下重量仅346克，比自家RF 50mm f/1.2L USM轻逾一半。470美元定价更颠覆了人们对F1.2镜头价格的认知。

佳能EOS R6 III单机身定价2799美元（约合人民币2万元），搭配RF24-105 F4 L IS USM镜头套装为4049美元。相较之下，尼康Z6 III采用部分堆栈式2400万像素传感器，定价2500美元；松下S1 II同样配备部分堆栈式2400万像素传感器，支持70张/秒连拍，售价3200美元；索尼A7 IV虽采用同级别3300万像素传感器，但缺失RAW视频拍摄功能。

Canon's EOS R6 III arrives with 7K RAW video and 40 fps burst speeds
It has a new (non-stacked) 32.5MP sensor to match Sony's A7 IV.
Canon just barged into the mid-range full-frame hybrid camera arena with a new entry. The 32.5MP EOS R6 III is a dramatic improvement over the EOS R6 II thanks to the higher resolution, faster shooting speeds and better video specs. However, it comes at a relatively high price and lacks a stacked or partially stacked sensor, unlike other cameras in this category.
The new 32.5MP sensor provides a big boost in resolution compared to the R6 II's 24MP chip. At the same time, the R6 III offers higher shooting speeds of 40 fps in burst mode with the electronic shutter, or 12 fps with the mechanical or first-curtain shutter. It also supports 20 frames (a half second) of pre-shooting so you won't miss key moments for wildlife or sports shooting.
The R6 III uses Canon's fast and dependable Dual Pixel AF system and comes with the company's latest AI tracking algorithms. It can operate in fairly dim conditions down to -6 EV and should be more responsive with Canon's latest Digic X processor, pending our review. It offers subject tracking for people, animals and vehicles, along with an Auto mode that will pick one of those automatically. It also borrowed the "Register People Priority" feature from the R5 II, which lets you keep focus locked on specific subjects that you've previously memorized.
The biggest update for the R6 III, though, is with video. Thanks to the higher resolution sensor, it can now capture up to 7K 60 fps RAW light video, 7K 30 fps "open gate" video and 4K at up to 120 fps, all with Canon's C-Log2 and C-Log3 on tap. There's a dizzying array of other video formats available (12 pages worth in the specs), with HEVC S, AVC-S, RAW, RAW Light and others, at resolutions up to 7K. All the AF subject detection features are available (vehicles, animals and people), and Canon is typically among the best for video AF in terms of speed and accuracy.
Nobody expects any radical design changes in a Canon camera (the company tried that with the EOS R and it really didn't work), so the R6 III kept the last model's tried and true form factor. That includes two adjustment dials on the top and one on the rear, along with a joystick, photo/video selector, mode dial and a good assortment of programmable buttons.
The rear display flips out as you'd expect for vlogging, but it doesn't tilt like Panasonic's S1 II — so it may obstruct the mic or headphone jacks, and isn't as useful for low-angle photo shooting. The viewfinder has 3.69 million dots of resolution as before, the same as Sony's A7 IV but less than Panasonic's slightly more expensive Lumix S1 II. One big change is the addition of a CFexpress card slot that allows RAW video capture and faster burst speeds, along with an SD UHS II slot. The battery is the same as the one for EOS R5 II and allows up to 390 shots (CIPA rating) with the viewfinder enabled.
Other features include waveform monitoring that will be much appreciated by pros, plus new focus speed algorithms borrowed from Canon's cinema cameras that offer "natural, professional" behavior, the company wrote. Inputs include 3.5mm mic and headphone jacks, along with high-speed USB-C and a full-sized HDMI port. In-body stabilization has been boosted slight from 8 to 8.5 stops, matching the latest Panasonic models.
Along with the EOS R6 III, Canon introduced some interesting new glass. The RF45mm F1.2 STM lens brings very high speeds and shallow depth of field to a much smaller and lighter .76 pound (346 gram) form factor — less than half the weight of Canon's RF 50mm f/1.2L USM lens. It's also shockingly cheap for an f/1.2 lens at $470.
The Canon EOS R6 III arrives later this month for $2,799 (body only) or $4,049 with the RF24-105 F4 L IS USM lens. That's a bit more than the Nikon's $2,500 Z6 III, which has a partially stacked but lower-resolution 24MP sensor. Panasonic's S1 II also has a partially stacked 24MP but can shoot at up to 70 fps and costs $3,200. Finally, Sony's A7 IV has a similar 33MP sensor but lacks the RAW video features of the R6 III.
