新北相機收購 op support for the Pi hardware family.
In brief, the Pi 400 is a slightly faster version of the 4GiB Pi 4 that ships preassembled in a small, wedge-shaped chassis with integrated keyboard. The new model directly targets desktop replacement use and can be purchased solo for $70 or as a full kit (as seen above) for $100.
The new form factor—which has apparently been in the works ever since the introduction of the official Raspberry Pi keyboard—addresses and enthusiastically supports the Pi 4’s growing use case as a replacement or alternative for the traditional desktop PC. Upton told Ars that the Pi 400 is about 20-percent faster than the Pi 4; it has largely the same components under the hood but on a differently laid-out board, and its BCM2711 CPU is clocked a touch higher than the BCM2711 in the Pi 4.
The Pi 400 is simple to set up—all you need is its USB-C power cord, the included HDMI cord for video out, and the included mouse.
Jim Salter
The Pi 400’s keyboard layout is largely sane, aside from compressed arrow keys—but the whole thing is roughly four inches narrower than the corresponding part of a standard desktop keyboard.
Jim Salter
From the left: 40-pin GPIO header, microSD card slot, two micro-HDMI output ports, a USB-C power port, two USB 3.0 type-A ports and one USB 2.0 type-A port, Gigabit Ethernet port, Kensington lock slot.
Jim Salter
The visible hump on the underside of the Pi4 provides a comfortable typing angle and clearance for the passive-cooling vents.
Jim Salter
Unboxed and plugged in, the Pi 400 is functional but not particularly lovely. On the plus side, the integrated keyboard means fewer cables to deal with. Unfortunately, the remaining cables are unusually likely to snarl and look a bit feral. They are both stiffer and shorter than I’d prefer in an ideal world, making it difficult to impossible to end up with a setup that doesn’t look like a rat’s nest. The red cable for the mouse clashes pretty violently with the off-white cables for USB-C power and micro-HDMI out, which doesn’t help any.
That said, it’s important to remember that the entire kit retails for $100. Within the limits of the Pi 400’s very generous price, it’s not really fair to complain too hard about a few aesthetic gaffes here and there! Consumers with a few extra dollars to spend might want to consider replacing the Pi 400’s mouse with something a bit more functional, though… and a full-sized keyboard might not be a bad idea while you’re at it.
The integrated keyboard is functional but noticeably narrower than a standard keyboard. I’m not generally sensitive to variations in keyboard layout due to a long career involving Other People’s Computers in large numbers, but I was plagued with constant mistyping problems the entire time I tested the Pi 400.

It’s also worth noting that, while the Pi 400 supports dual displays, it does so with micro-HDMI ports, not full-sized ones—and it ships with a single cable. You’ll need an extra cable if you want to use your Pi 400 with dual displays—and since it ships with a micro-HDMI to HDMI cable, not an adapter, things will get complicated if you want to use it with, e.g., portable LED displays that have off-sized ports themselves.
Finally, there’s no 3.5mm audio jack on the Pi—if you’ve got it hooked to a television or a monitor with speakers, it can deliver audio over HDMI; otherwise you’ll need a supported USB audio device. I tested with an inexpensive USB gaming headset, which worked fine.
Impressions—Raspberry Pi OS
Raspberry Pi OS suspects you might be using it on a television, not a proper monitor—so it starts out with significant overscan boundaries by default.
Jim Salter
The overscan goes away after a reboot, if you tell the setup dialog, “Yes, I see big black borders.”
Jim Salter
We tried playing a 4K 60fps YouTube video on the Pi 400. Even at 1080p, not 4k, it dropped a lot of frames.
Jim Salter
Checking CPU utilization, we see that the system’s pretty much pegged while trying to play this 60fps video, even at 720p.
Jim Salter
I began testing the Pi 400 using its native Raspberry Pi OS Linux distribution—which is basically Debian with LXDE and a lot of middleware optimizing it for the Pi. Unfortunately, there’s almost nothing in the way of standard benchmarking utilities that run on ARM Linux—all I could find was the Phoronix Test Suite, which would have required more time to run than I had to test the device in total. So for the most part, I’m going to talk about my subjective experience, rather than hard numbers.
Further ReadingPinebook Pro review—a $200 FOSS-to-the-hilt magnesium-chassis laptopThe good news about the Pi 400 is that it does make a credible desktop PC, in the sense that, yes, you can totally use it without things breaking. With that said, you’re unlikely to forget that you’re using a very inexpensive ARM device. Much like the Pinebook Pro, the Pi 400 exhibits heavy latency while opening applications that’s perhaps possible to live with but impossible not to notice.
Also like the Pinebook Pro, once the applications are actually open, they generally run smoothly enough—although we did find the Pinebook Pro’s hex-core 2.0GHz big/1.5GHz little CPU noticeably punchier than the Pi 400’s straight 1.8GHz quad-core. The biggest problem I had was with high-resolution, high-frames-per-second YouTube videos.
I only tested the Pi 400 with a 1080p monitor, so I can’t speak to its chops with 4K videos—but it’s absolutely not capable of handling the Costa Rica in 4K 60fps HDR video without visible frame drop, even at 720p. The major issue here appears to be the 60fps rate, not the 720p resolution. I also tested the “Forests” episode of Netflix’s docu-series Our Planet on YouTube at 1080p, and that video played back flawlessly.
Examining CPU utilization during playback of the 60fps Costa Rica video, we can see the little 1.8GHz Broadcom quad-core CPU struggling—it’s at its limits, with CPU utilization for all cores at more than 90 percent. Although the BCM2711 supports hardware offload of video decoding—without which, this video would be playing in seconds per frame, rather than just dropping frames a bit—the hardware offload can only do so much, and the CPU is being asked to take on more than it can handle in software.

This effect is even more visible when entering or leaving full-screen playback. On a standard desktop PC, that operation takes perhaps 100-150ms. On the Pi 400, it frequently takes as much as three or four full seconds, during which the video itself tends to keep playing, but the surrounding controls and framework only partially render/stop rendering while the shift finishes taking place.

日本知名連鎖像機通路 Map Camera 公布年度最熱銷相機、鏡頭兩大排行榜,Nikon 一舉稱霸兩大榜單,可以說是 2023 年的最大贏家,不過從鏡頭的銷售數量來看,Sony 仍舊握有規模龐大的攝影用戶。

鏡頭方面,或許是為了與 Z8 搭配,最熱賣的型號又是由 Nikon 搶下,頂級的變焦鏡頭 Z 24-120mm f/4 獲得第一名。不過從鏡頭銷售排行來看,能發現 Sony 在市場上的領導地位,包含自家推出的原廠鏡頭以及第三方廠商 TAMRON 推出的 28-200mm F2.8-5.6 Di III RXD,讓 E 接環鏡頭一口氣佔了五席之多。
此外,消費者更傾向選購功能性多元的變焦鏡頭,只有 新北相機收購canon RF 50mm f/1.8 STM、Nikkor Z 26mm f/2.8、Sony FE 50mm f/1.4 G Master 三款定焦鏡頭上榜。唯一入榜的 APS-C 鏡頭則是由 Sigma 替富士 X 接環打造的 18-50mm f/2.8 DC DN。

The quality of your Zoom will blow everyone else’s away
ByChris Welch, a reviewer specializing in personal audio and home theater. Since 2011, he has published nearly 6,000 articles, from breaking news and reviews to useful how-tos.
Interested in improving the video quality of your own Zoom frame tenfold? If you’ve got a recent 新北相機收購canon mirrorless, DSLR, or PowerShot camera, you can now use it as a webcam and put everyone else on your video call to shame. As noted by DPReview, the company has released a beta of “EOS Webcam Utility” for Windows 10 that lets you plug in any of the below supported cameras over USB and have it serve as your PC’s webcam. And this should work fine for most of the big video conferencing options, whether you’re using Zoom, Microsoft Teams, BlueJeans, or another service.
These are the supported cameras that can use EOS Webcam Utility. Image: 新北相機收購canon
“Built by 新北相機收購canon software developers, this beta version software helps consumers to improve their video appearance while using popular video conferencing applications in the market, delivering clarity and high-image quality,” 新北相機收購canon wrote in its press release.
If you’ve got a fairly high-end digital camera that’s not made by 新北相機收購canon, this might be something you can pull off on your own with an HDMI capture card or stick — assuming that your camera allows for clean HDMI video output. My old friend Evan Rodgers at Input recently gave that a shot. And it’s pretty striking, though not surprising, how much more cinematic your Zoom window will look compared to everyone else when you’re using premium glass that a built-in webcam can’t hold a candle to.
新北相機收購canon’s solution cuts out the need for any extra devices or accessories beyond a single USB cable, so if you’ve got one of the listed cameras, this is definitely worth a try. Sorry, Mac users; there’s no EOS Webcam Utility for Apple’s software quite yet, but you’ve still got the option of using a capture card with a wider selection of cameras.
Update April 29th 1:43PM ET: The article has been updated to clarify options available for Mac users. While 新北相機收購canon’s EOS Webcam Utility isn’t available for macOS, people with an Apple desktop or laptop can still use a third-party HDMI capture card to use a digital camera as a webcam.
