実証データ
Performance
The autofocus is the star here, and it's not even close. Sony's Real-Time Eye AF locks onto human and animal eyes in 0.02 seconds, and in our testing it's still one of the best systems on the market. The 24.2MP APS-C sensor sits in the 89th percentile, which means image quality is a standout, especially for product shots where detail matters. Burst shooting at 11fps with AF tracking is solid, though not class-leading anymore. The surprise? Video. You get oversampled 4K at 30fps with S-Log2 and S-Log3, which is more color flexibility than most cameras at this price offer. The EVF, though, is a letdown. It's small, low-res, and feels like an afterthought compared to the rest of the package.

vs Competition
The Fujifilm X-H2S is the obvious step-up if you need serious video and burst speed, but it costs nearly three times as much. The Canon EOS R6 Mark III gives you full-frame low-light performance and better stabilization, but again, you're paying a premium. The Nikon Z6 III splits the difference with a better EVF and build quality, but its AF still trails Sony's. For pure value in APS-C, the a6400 holds its own against all of them, but the Panasonic S5 IIX is the one to watch if video is your main gig and you can stretch the budget. It has better stabilization and open-gate recording, though its autofocus is a step behind.

Value & Pricing
At $1,020 with the bundle, this is a fair deal, not a steal. The body alone has aged well, but you're paying for accessories that are mostly budget-tier. The spare battery and 64GB card are genuinely useful. The tripod and cleaning kit are the kind of stuff that ends up in a drawer. If you can find the body-only for less and buy a better lens, do that. But as a complete starter kit, it's reasonable.
詳細情報
Overview
The Sony a6400 is the camera you buy when you want pro-level autofocus without selling a kidney. It's been around since 2019, but that 425-point AF system still embarrasses cameras twice its price. The headline here is the bundle, you get the 16-50mm kit lens, a 64GB card, spare battery, bag, and a pile of accessories for around $1,020. That's a genuinely solid starter kit for anyone jumping into mirrorless.
But let's be real about what this is. The a6400 is a creator's camera first. It nails product photography, handles YouTube talking-head shots beautifully, and the flip-up screen makes vlogging painless. It's not a travel companion, and the lack of weather sealing plus that dated EVF will bug you if you're shooting outdoors in rough conditions. Still, for the money, the core imaging chops are hard to argue with.
Common Questions
Q: Is the a6400 good for beginners?
Yes, with a caveat. The menus are classic Sony, which means they're cluttered and annoying at first. But the autofocus is so reliable that you'll get sharp shots while you're still learning exposure. The flip screen helps for selfies and vlogging too.
Q: Can I use this for professional video work?
For talking-head YouTube, product demos, and B-roll, absolutely. The oversampled 4K looks sharp, and S-Log gives you room to grade. But there's no 10-bit internal recording, so heavy color grading will show banding. For client work that demands 10-bit or 4K60, look at the Panasonic S5 IIX or Fujifilm X-H2S.
Q: Does the kit lens have image stabilization?
Yes, the 16-50mm f/3.5-5.6 II has Optical SteadyShot built in. It helps for handheld video and slower shutter speeds, but it's not a replacement for a gimbal or tripod. The camera body itself does not have IBIS, so stabilization comes entirely from the lens.
Who Should Skip This
If you shoot in rain, snow, or dusty environments, this isn't your camera. No weather sealing means one bad outing can fry it. Go get a Fujifilm X-T5 or an OM System OM-1 Mark II instead, both are built like tanks. If you need 4K60 or 10-bit internal video, skip this and look at the Panasonic S5 IIX.
Verdict
Buy the a6400 if you want reliable, fast autofocus and solid 4K video without spending over $1,500. It's a workhorse for product shots, YouTube, and portraits. Just know you're getting an older EVF, no weather sealing, and a kit lens that's fine but not exciting. If you shoot outdoors in rough weather or need top-tier video features, save up for something tougher.
