Samsung ISOCELL GN2 does 480fps!

The hegemony of phone sensors has been the purview of Sony with their Exmor sensors for many years but now Samsung has started making inroads in the space with their ISOCELL chips. The latest is currently mass-produced and shipping in handsets already which is not a paper launch, but a real thing. The chip is capable of massive low light improvement compared to other sensors because it is essentially a near 1″ sensor with 1/1.12-inch measurements. This is close to what Sony RX cameras use as a main sensor, and a first for a phone.

As to how they are able to fit this sensor on phones, it is a dance between a protruding camera bump that is a little larger than usual and also a lens system that creates a full imaging circle from a minute distance. The GN2 is capable of recording 480fps in HD 720p, 4k 120fps, 30fps in 12.5MP windowed size and 10fps in 100MP mode which uses a clever algorithm and three RGB exposures to derive a 100MP image from the 50MP source. → Continue Reading Full Post ←

Fujifilm X-E4 Slow Motion 240fps disappoints!

Fujifilm X-E4 Slow Motion

The recently released camera called the Fujifilm X-E4 shares many of the traits of their lower brethren but also from the higher-end models in a compact package. It ditches the better viewfinder for a small 2.36 million dot EVF that makes it a bit hard to see your composition but that also allows the camera to be smaller and more stylish than the beefy SLR style Fujis out there.

The Fujifilm X-E4 Slow Motion feature is the same as found on cameras like the excellent Fujifilm XS-10 which is a 120fps or 240fps full HD component that records in camera. Why are we not excited? well, the quality is lower than expected with some aliasing and moire characteristics that are so last decade. When are manufacturers going to offer the same 1080p quality at all frame rates instead of relegating the 120fps and 240fps modes to the lower bitrate and detail bin?

Fujifilm X-E4 Main Specs:

  • 26.1MP APS-C X-Trans BSI CMOS 4 Sensor
  • DCI/UHD 4K at 24p, 25p & 30 fps
  • 2.36m-Dot 0.62x OLED EVF
  • X-Processor 4 Image Processor
  • Compact classic body
  • 3.0″ 1.62m-Dot 180° Tilting Touchscreen
  • 425-Point Hybrid AF System
  • Film Simulation Modes
  • Bluetooth and Wi-Fi Connectivity
  • Lens Kit includes: XF 27mm f/2.8 R WR Lens
  • MSRP: 1,049.00 USD Lens Kit or $849.95 Body only!
  • Release date March 11th, 2021

Fujifilm X-E4 Slow Motion Specs:

Full HD (1920 x 1080)

  • 50p/59.94p
  • 100p/119.88p
  • 200p/239.76p
  • [100 to 200 Mb/s]

While we get the same frame rates as the best value/performance on Fuji’s arsenal the XS-10, you get the aliased version of the footage. While the final quality is passable for your Youtube Vlog, it will not be ready for more professional uses, the pixelation and stair-stepping looks like badly captured 720p video in a 1080p wrapper.

The video below by the amusing and great Kai W, has a sample of 200p video on the camera at the 4-minute mark.  You can clearly see the aliasing in the footage when you load it at full resolution.  We expect the 120fps mode to be much better but we already get pretty good 120p footage from most cameras nowadays. The 240fps mode is the standout here and it disappointed us fully.

But what about?

Can you still make a remarkable slow motion shot with this camera?  In a word, Yes take a look at the Fujifilm’s XS-10 240fps mode which is probably the same as the one in the X-E4 as they share a lot in common feature-wise. Look closely at the very well shot video below:

Sony A1 Slow Motion has 8x Mode!

Sony A1 Slow Motion

Just in time for the Japanese Olympics if they ever take place, Sony has released the Sony Alpha 1 or A1 for short which is probably the most powerful mirrorless camera ever produced.  Customary for Japanese camera manufacturers in Olimpic years, the likes of Canon and Nikon have released their professional flagship products like the  1DX and D6 which are still SLR mirrored products that have the highest possible Autofocus features for a camera of that type as well as speed and dependability.

Sony has had some inroads in that space with the Sony a9 series but they were missing a higher megapixel count version that could really differentiate it from the pack and the A1 seems to be just that kind of product. By shooting 8k video at 24,25 and 30p it becomes future-proof for the next decade as far as resolution goes and by taking 30 images per second in stills mode at the full 50MP resolution with AF Tracking, it is one blinding fast beast.  The fact that it also shoots 120fps 4k and 240fps Full HD doesn’t hurt it either.

The Sony A1 is probably the fastest mass production professional hybrid camera ever made. The speed required for 50 megapixels at 30fps means that it is processing and saving in RAW format or RAW+JPG to CF Express Cards  at 1.5 Billion Pixels/Second and all of this while using the 120Hz continuous intelligent Auto Focus for people and animals.

We have confirmed that the camera has a 21 Megapixel crop factor in APS-C size for stills and possibly video which probably means that all the higher 1080p frame rates are possibly extracted from the crop area of the sensor and not from the full 50MP area.

Xiaomi Mi 11 Slow Motion has a 480fps mode!

Xiaomi Mi 11 Slow Motion

There are many new phones about to be announced including the most awaited Samsung release of the year, the Galaxy S21 which is due in a day or so. However the Xiaomi Mi 11 which was recently announced has been making a great impression on reviewers with a fluid 120Hz display, above-average camera features, 8k video, and our main interest the slow motion recording modes.

The high speed mode includes a 240fps 1080p mode but most interestingly this extends to 1080p 480fps which might be of comparable quality.  The Xiaomi brand has been making cameras and phones for a few years now and while it is usually discounted as a budget brand, the inclusion of pro features like a Snapdragon 888 processor and a whopping 108MP main camera make it stand apart.

Xiaomi Mi 11 Slow Motion Modes:

Main Camera:

  • 4k video at 30p/24p/60p
  • 1080p Full HD: 30/60/120/240/480fps
  • 8K video recording: 24/30fps

Selfie Camera:

MAIN CAMERA Triple 108 MP, f/1.9, 26mm (wide), 1/1.33″, 0.8µm, PDAF, OIS
13 MP, f/2.4, 123˚ (ultrawide), 1/3.06″, 1.12µm
5 MP, f/2.4, (macro), 1/5.0″, 1.12µm
SELFIE CAMERA Single 20 MP, 27mm (wide), 1/3.4″, 0.8µm
Features HDR, panorama
Video [email protected], [email protected]
PLATFORM OS Android 11, MIUI 12.5
Chipset Qualcomm SM8350 Snapdragon 888 (5 nm)
CPU Octa-core (1×2.84 GHz Kryo 680 & 3×2.42 GHz Kryo 680 & 4×1.80 GHz Kryo 680
GPU Adreno 660

MSRP Price: $739.74

We are happy to see such a plethora of frame rate and a very high-end performance package all for under $1000USD, in fact, it has an under $750 price tag which is very tempting.

We are also happy to see 120Hz becoming commonplace as a default refresh technology for displays on most mid to high end phones. This makes the experience fluid and for slow motion video it allows you to see 120fps live if needed before getting to a video editor.

Xiaomi Mi 11 Slow Motion Samples:

We found what we assume are legitimate samples of the slow motion mode. The quality is not class-leading but not that awful either. You be the judge:

GoPro Hero 9 Black Slow Motion Fail!

Gopro Hero 9 Black Slow Motion Fail

GoPro has released the Hero 9 Black and in many respects, it is the best camera they have ever made. It is a little larger to accommodate a slightly larger battery and screens and it offers a new 5k mode that is very filmic like with pretty good dynamic range.  It has Hypersmooth 3 technology which does away with most gimbal situations and it can serve as a minute and reliable blog camera.

However, the GoPro Hero 9 Black is in some ways the end of an era for GoPro and the action camera market. It now heralds a new subscription model that aims to hook their market with a  lower price for the camera if the subscription to GoPro.com is added at check out.  Gone are the days of class-leading technology and in are the days of survival at all costs. Can we really blame GoPro for trying to make it?

GoPro Hero 9 Black Main Features:

  • 23.6MP Sensor, 5K30 Video & 20MP Photos
  • 240fps 1080p Video* 8x Slo-Mo
  • Live View Front Display/Rear Touchscreen
  • Webcam Mode & 1080p Live Streaming
  • HyperSmooth 3.0 Image Stabilization
  • 33′ Waterproof without External Housing
  • PowerTools & Protune Feature Suites
  • Time-Lapse & Night-Lapse
  • Built-In Flip-Out 2-Prong Mount
  • 30% Longer 1720mAh Capacity Battery

1080p Frame rates:

  • Linear Lens 240, 120, 60, 30, 24 fps
  • Linear + Horizon Leveling 240, 120, 60, 30, 24 fps
  • Narrow Lens 240, 120, 60, 30, 24 fps

2.7K Frame Rates:

  • Wide Lens 120, 60 fps
  • Linear Lens 60, 30, 24 fps
  • Linear + Horizon Leveling 60, 30, 24 fps
  • Narrow Lens 60, 30, 24 fps

If you decide to get a Hero 9 which in our view is still the best action camera you can buy, you may be inclined to lower your cost by subscribing to GoPro.com and shaving $100USD from the camera price.

HERO9 Black

$349.98 includes

1-year subscription to GoPro1

or
$449.99
without subscription Subscribing to GoPro gets you:

  • Unlimited cloud storage
  • Up to 50% off at GoPro.com2
  • Total camera replacement3

32GB SD card included

So what is wrong with this camera?

There are few things we don’t like on this camera which is a good thing, it has outstanding 5k 30fps footage, it has larger screens and better Hypersmooth in 4k, it has a larger battery, and it is a very refined product with a  quality build. It is in fact the best GoPro we have ever seen but sadly there are things we need to mention.

GoPro Hero 9 Black Slow Motion Fail:

The biggest issue we have is the stagnation of 1080p frame rates. 120 and 240fps in full HD remain essentially the same quality as they were in the Hero 6 Black.  Sure you get better Hypersmooth stabilization in 240p but quality-wise, the pixelation, and overall soft look of the slow motion footage is here with no apologies.

There has not been a consolidated effort to offer 480fps or even 320fps footage in 1080p even as the camera has grown to accommodate 4k 60p and 5k 30p recording modes.  In other words, slow motion is mostly frozen in place except for one little glimmer of hope. GoPro needs to become a leader in frame rates again, it was and still is one of the most important considerations for its users.

That hope is in the form of 2.7k at 120fps which is detailed, offers excellent color and dynamic range for such a small camera and sensor. They did a really good job extracting those 120 frames and we feel that this should be your default slow motion option on this camera. 1080p is simply to soft to even consider it for full HD quality, it is still more like a 720p upscaled mess.

5k is essentially the star on this camera and it is probably the main reason to get this camera over the Hero 8 Black.

iPad Pro Slow Motion includes 240fps!

iPad Pro Slow Motion

The iPad Pro has been making accessible the best iPhone Camera features for a few years now and the latest 2020 model seems to be in lockstep with the iPhone 11 Pro but with only 2 cameras instead of 3.  However, the quality is close but not as good lens wise, but they make up with a new LiDAR scanner in place of the third camera lens that makes it possible to accurately scan physical objects and surroundings to improve AR capture and interaction.  The demos are early but the technology holds promise.

What interests us at HSC is the slow motion features and we see a continuation of the iPhone 11 Pro and 11 camera modes with Wide and ultra-wide cameras supporting all slow-mo modes of 60, 120 and 240p which is identical to the mobile line up.  We looked at the iPhone 11 Pro’s camera quality which impressed us with the best 240p and 120p quality on a phone to date see here

Camera Specs:

  • Wide: 12MP, ƒ/1.8 aperture
  • Ultra Wide: 10MP, ƒ/2.4 aperture, and 125° field of view
  • 2x optical zoom out; digital zoom up to 5x
  • Five‑element lens (Wide and Ultra Wide)
  • Brighter True Tone flash
  • Panorama (up to 63MP)
  • Sapphire crystal lens cover
  • Backside illumination sensor
  • Hybrid IR filter
  • Autofocus with Focus Pixels (Wide)
  • Tap to focus with Focus Pixels (Wide)
  • Wide color capture for photos and Live Photos
  • Exposure control
  • Noise reduction
  • Smart HDR for photos
  • Auto image stabilization
  • Burst mode
  • Timer mode
  • Photo geotagging
  • Image formats captured: HEIF and JPEG

While you would not want to buy an iPad Pro 2020 for its slow motion performance, it is encouraging to see that it will perform as good as the mobile iPhone version.  The larger size makes it harder to maneuver if handheld but it also helps with stability by shaking much less.  In slow motion, however, it makes little difference to have stabilization if you are just holding normally and don’t have a large peak in motion.  The higher the shutter speed the more clarity you will get at high frame rates but that also calls for more light in the scene.

Video Recording  Specs:

  • 4K video recording at 24 fps, 30 fps, or 60 fps (Wide); 60 fps (Ultra Wide)
  • 1080p HD video recording at 30 fps or 60 fps
  • 720p HD video recording at 30 fps
  • Brighter True Tone flash
  • Slo‑mo video support for 1080p at 120 fps or 240 fps (Wide); 240 fps (Ultra Wide)
  • Time‑lapse video with stabilization
  • Cinematic video stabilization (1080p and 720p)
  • Continuous autofocus video
  • Noise reduction
  • Take 8MP still photos while recording 4K video
  • Playback zoom
  • Video geotagging
  • Video formats captured: HEVC and H.264

iPad Pro Slow Motion Sample?

As you might expect with a product so new we have no samples at this time but according to the excellent first look review below you can probably tell the iPhone 11 and 11 Pro will have slightly better camera quality than the iPad Pro 2020. Why did Apple not just include all the same camera modules as the other phone variants? Well, it comes down to cost, in order for it to be sub $1k they had to cut corners and created a cheaper optical and DSP system for imaging. It is still remarkably good but not a champ like the ones in their flagship phones.

iPad Pro (2020) Review by Rene Ritchie:

We will have slow motion samples in a future post, we don’t feel the iPad Pro 2020 is worth it if you need slow motion video or 4k 60. You can get better quality in a more portable device on the iPhone 11 line. However, if you are an iPad user and need to upgrade from the iPad Pro 2018, we feel there is no question this new iPad along with the floating keyboard will be an ideal setup.

We don’t expect video quality to be masterful here but we don’t think it will be bad at all.  All in all a great overall product that is, of course, expensive but if you want the best Apple can offer you will have to pay up.  We will re-visit this device when slow motion 120p and 240p samples start to be available in quantity.  -HSC
