Shoot for the stars with the Canon EOS Ra

Canon has produced its first full-frame camera for astronomical photography – taking pictures of deep space and constellations.

Published

on

Canon builds on its iconic full-frame range and EOS R System line-up with the launch of the EOS Ra, which is its first full-frame camera for astronomical photography.

The EOS Ra, unlike other full-frame astro cameras, is portable and has no need for external power and connection to a computer, resulting in exceptional image quality of visible reality, but also of deep space photography with a wide range of optical devices.

The camera shares features with the September 2018-launched EOS R. The EOS Ra inherits the camera’s fast autofocus, the ability to focus in light conditions as low as -6EV, a 35mm full-frame CMOS sensor with approximately 30.3 million effective pixels and a DIGIC 8 image processor. While boasting this advanced and cutting-edge optical technology, the EOS Ra is a modified EOS model – developed in direct response to the specific needs of astrophotographers looking to capture the vivid colour of deep space and constellations.

Featuring a new infrared blocking filter (IR filter) allowing even higher hydrogen-alpha (Hα) light to reach the imaging sensor, it enables four times as much of this hydrogen-alpha light to be transmitted compared to the EOS R. Photographers can capture, both crisply and clearly, the distinct red colour of nebula – an interstellar cloud of dust made up mostly of hydrogen and helium – impossible to capture on a traditional camera where the UV/IR cut filters block the IR light that gives these nebulae their red colour.

With its mirrorless design and full-frame sensor, the EOS Ra is a camera for photographers looking to capture images of deep space. With no mechanical mirror system, vibrations are minimised ensuring sharp images. What’s more – the high performing Canon-developed sensor offers a mix of high ISO performance, impressive resolution, fast readout and exposure latitude, helping to create interstellar images of exceptionally high quality.  

With Dual Pixel CMOS Auto Focus (AF), the EOS Ra features a range of AF and MF focus functions ensuring images are of high optical excellence – including shots captured in low-light conditions. Retaining the -6EV AF from the EOS R, low-light performance with RF lenses and existing EF lenses is possible. When astrophotographers use it with a telescope, focus assist functions like focus peaking and magnification up to 30x – that’s three times more than the EOS R – ensure focusing with any optical device is fast. What’s more, with its 4K movie and 4K time-lapse capabilities the EOS Ra is also the first astro camera on the market with a 4K movie function.

Sharing the same mount as the EOS R, the EOS Ra has been designed to enhance lens design possibilities. The RF lens mount enables a radical new optical design – the 20mm flange back and wide 54mm mount diameter has made it possible for Canon engineers to design new lenses that weren’t achievable before. The camera, and system is also compatible with three lens mount adapters, giving photographers a wide choice of lenses and telescopes to use with EOS Ra.  More than 70 EF and EF-S lenses can be used with Canon’s innovative EOS R System, adding new functionality to existing optics, while maintaining the excellent levels of performance and functionality previously seen with EOS DSLRs. As when attached to an EOS R, the Canon mount adapter enables users to maintain their setup whether using RF or EF and EF-S mount lenses.

The EOS Ra’s compact and lightweight design makes it easier to attach to a telescope – suitable for photographers shooting for long periods of time. Combining existing EOS ergonomics with new controls the camera provides maximum control with familiarity. The Vari-Angle touch screen makes the camera comfortable for photographers shooting in many positions, with the benefit of having up to 30x magnification to check focus. The EOS Ra’s electronic viewfinder means photographers can really shoot what they see, with the ability to view their subjects clearly in the dark.

The EOS Ra, like the EOS R, supports connection via EOS Utility and the Canon Camera Connect application. This allows remote camera control for still and video via USB or via wireless. The software can be downloaded free of charge from the Canon support website – enabling remote shooting, for example from indoors on a cold evening, and time-lapse operation.

Huawei P40 Pro gets best camera score

Independent camera benchmarking company DxOMark has given the Huawei P40 Pro its highest rating yet. Read about what makes it better than the competition.

Published

on

The Huawei P40 Pro is the manufacturer’s latest high-end smartphone. It features the Kirin 990 5G chipset, a 6.58-inch Full-HD+ OLED display with rounded edges, and dual front camera. Huawei tends to use the P-series models to showcase the company’s latest mobile camera technologies, and its P-series flagship device for 2020 is no different. 

DxOMark provided the following summary of the camera’s latest features and what they mean for the device’s performance: 

Main camera 

The primary camera comes with a very large 1/1.28″ 50MP Quad-Bayer sensor that produces 12MP image output. As with other devices with similar sensors, it uses pixel binning to increase dynamic range and low-light capabilities. The lens features an f/1.9 aperture and nominal 23mm-equivalent focal length, however, Huawei crops the field of view to a more conventional 27mm. This decision was presumably made in order to design a thinner camera unit, but it should also help with reducing such artifacts as corner softness and distortion. Optical image stabilization, which can be challenging to implement on such large image sensors, is on board as well. 

Ultra-wide camera 

Like with the Mate 30 Pro, Huawei implements a large and high-resolution image sensor (40MP 1/1.54″) in its ultra-wide camera, which combined with a fast f/1.8 lens, should make for excellent low-light image quality. The downside of such a large sensor in the ultra-wide is lens design. It’s a challenge to design a lens that provides a very wide angle of view and still fits into the thin body of a high-end smartphone. Therefore, Huawei settled on a compromise at 18mm, which is noticeably wider than the main camera, but not as wide as that of some competitors, such as the latest Samsung devices and iPhones, which offer 12mm and 13mm lenses, respectively. 

Tele-camera 

The P40 Pro’s tele-camera comes with similar technology to last year’s P30 Pro. The module is optically stabilized and uses folded optics to achieve a 5x optical zoom factor (125mm equivalent). 

“Field-of-view fusion” zoom 

The P40 Pro doesn’t rely just on hardware alone for zooming, however. Like the P30 Pro, the P40 Pro uses software systems which Huawei calls field-of-view fusion and AI RAW, a combination of optical and algorithm-powered digital zooming that adapts to the chosen magnification factor. Only the primary camera is used for up to 2x magnification; the tele-camera takes over from 5x and longer. For intermediate zoom factors, the P40 Pro uses a fusion algorithm that combines image data from both cameras, merging several RAW frames from the main and tele cameras into one high-resolution frame, which is then cropped for zooming. 

For optimal detail, the 5x tele-cam records image data at the centre of the frame; it uses AI-refined image data from the primary camera to fill in the “missing” image areas around the edges. A deep learning algorithm improves detail on fine patterns and textures—quite an impressive feat, considering that autofocus, white balance, and other image parameters of both cameras all have to be in perfect sync for good results. 

At the long end, the camera is capable of achieving a 50x zoom factor using a combination of optical zoom and super-resolution processing that stacks multiple RAW frames from the tele-cam. 

Improved bokeh mode with AI RAW and super-resolution 

While the P30 Pro used AI RAW only for zooming, the P40 Pro now applies the technology to most camera modes, including bokeh. This means that as with zoom shots, bokeh images from the new model offer a wider dynamic range. The camera uses the 50MP high-resolution sensor and an AI RAW-powered super-resolution algorithm to generate an image with a 54mm-equivalent focal length and very good detail rendering. Data captured by a time-of-flight (ToF) laser measures the distance to objects in the scene, and is then used to confirm and fine-tune the initial depth-map that the primary and super-wide cameras generate. 

Improved white balance and colour rendering with multispectral sensor 

The P40 Pro also comes with a new white balance system that uses a semantics-based neural network and data-driven methods for more accurate white balance. The system also gets help from a multispectral sensor that can measure specific colours more accurately than the image sensor. 

Autofocus with dual phase detection on all sub-pixels 

The new autofocus system comes with dual phase detection on all sub-pixels and can use all pixels for autofocusing. In low light, the system also makes use of subject distance information that the ToF laser sensor captures. 

Key camera specifications: 

  • Quad camera setup, including ToF sensor 
  • Primary: 50MP 1/1.28″ sensor (12MP output), 23mm-equivalent (1x defined as 27mm) f/1.9-aperture lens, full-pixel Octa-PD, OIS 
  • Ultra-wide: 40MP 1/1.54″ sensor, 18mm-equivalent f/1.8-aperture lens, PDAF 
  • Tele: 12MP 1/3.56″ sensor, 125mm-equivalent f/3.4-aperture lens, PDAF, OIS 
  • ToF 3D depth-sensing camera (78-degree FOV) 
  • LED flash 
  • 4K video, 2160p/60fps (2160p/30fps tested); default is wide-angle camera 1080P/30fps 
  • Multispectral colour temperature sensor 

Please note: The Huawei P40 Pro was tested with European firmware which by default has AI set to off. In other regions the feature is activated by default. The camera firmware used for the DxOMark tests is not yet currently available to consumers. Huawei will make it available as an update in the near future.
