Canon has launched the EOS 60Da, a variant of its 60D DSLR tuned for astrophotography. The camera features a re-worked infra-red filter leaving the camera more sensitive to a specific emission frequency (656nm) of hydrogen, key to capturing images of features such as nebulae (gas clouds) in space. The 18MP camera continues where 2005’s 8MP EOS 20Da left off. It will be available from a limited number of authorized dealers at a price of around $1499.00/£1174.99.
NEW CANON EOS 60Da DSLR CAMERA FOR ASTRONOMY ENTHUSIASTS CAPTURES THE TRUE COLORS OF THE COSMOS
Canon U.S.A., Inc., a leader in digital imaging solutions, today introduced the EOS 60Da Digital SLR Camera, a long-awaited successor to the EOS 20Da that is optimized for astrophotography. This DSLR caters to astronomers and hobbyists who enjoy capturing the beauty of the night sky by offering a modified infrared filter and a low-noise sensor with heightened hydrogen-alpha sensitivity. These modifications allow the camera to capture magnificent photographs of “red hydrogen emission” nebulae and other cosmic phenomena.
“The EOS 60Da is a testament to the constant desire to meet the needs of every customer, including those in specialized fields,” said Yuichi Ishizuka, executive vice president and general manager, Imaging Technologies & Communications Group, Canon U.S.A., “This new camera enables an accurate depiction of a part of our solar system which is hard to achieve with conventional cameras but should be enjoyed and celebrated.”
The Canon EOS 60Da camera packs a powerful 18-megapixel CMOS sensor (APS-C) that produces sharp and high-contrast images of astronomical objects, a major enhancement over the EOS 20Da model’s 8.2-megapixel sensor. The improved infrared-blocking filter is a modification suited specifically toward astronomy enthusiasts to achieve a hydrogen-alpha light sensitivity that is approximately three times higher than that of a normal Canon DSLR camera. This produces a 20-percent higher transmittance of Hydrogen Alpha line, or Hα wavelength, allowing astronomers to capture crisp, clear images of reddish, diffuse nebulae.
Crisp images of the stars and planets can be viewed on the EOS 60Da’s improved 3.0-inch Clear View LCD screen with 1,040,000 dots for detailed focusing. The flip-out Vari-angle screen allows photographers to adjust the screen for easy viewing without straining even while the camera is mounted to a telescope via a third-party T-ring adapter. Optimized for stargazing with friends or in an educational setting, astronomy enthusiasts can connect the camera to a TV with the provided AVC-DC400ST Stereo AV Video Cable and display the night sky on a TV monitor using the camera’s Live View mode. Moreover, the EOS 60Da’s Live View mode is equipped with a Silent Shooting feature that eliminates shutter-induced vibration for maximum camera stability when the camera is mounted to a telescope or super-telephoto EF lens.
Enhanced noise reduction on the EOS 60Da sensor offers photographers the ability to experiment with the wide array of ISO settings and increased ISO speeds up to 6400 expandable to 12800. Other features include an intelligent nine-point autofocus system, full manual controls, and RAW, JPEG, and RAW+JPEG image recording capabilities.
The EOS 60Da helps capture the wonders of the night sky with its use of Canon’s award-winning EF and EF-S lenses along with other EOS accessories. Additionally, the EOS 60Da is packaged with Canon’s RA-E3 Remote Controller Adapter, providing the ability to connect a Canon Timer Remote Control such as the TC-80N3 (optional accessory). The TC-80N3 is ideal for controlling time exposures longer than 30 seconds as well as capturing a series of consecutive time exposures that can be composited during post-processing for improved image quality. This is especially useful when the camera body is connected to a telescope[i] or an EF super telephoto lens.
Canon has also included an AC adapter kit with the EOS 60Da, allowing the camera to be powered through an AC wall outlet or a battery-powered inverter, ideal for long exposure image or video capture at home or in the field.
As a specialized product, the EOS 60Da is only available to order from select authorized dealers. The estimated retail price is $1,499.00 and it is expected to be available this month.

Tamron has announced a 24-70mm F2.8 zoom for full frame cameras that features inbuilt optical stabilisation – a first in this class of lens. The SP 24-70mm F/2.8 Di VC USD, to give it its full name, also incorporates an Ultrasonic Silent Drive motor for autofocus, which allows full-time manual focus. The lens is moisture-resistant, and features a circular aperture diaphragm for the attractive rendition of background blur. It will be produced in Canon, Nikon and Sony mounts, with price and availability to be confirmed at a later date.
Tamron develops full-size, high-speed standard zoom with built-in image stabilization – SP 24-70mm F/2.8 Di VC USD (Model A007)
Tamron Co., Ltd., a leading manufacturer of optical equipment, announced the development of the SP 24-70mm F/2.8 Di VC USD (Model A007), a full-size high-speed standard zoom lens equipped with VC (Vibration Compensation) image stabilization and USD (Ultrasonic Silent Drive), with resolution at the top of its class.
The price and availability of the SP 24-70mm will be announced at a later date.
- A full-size, high-speed standard zoom with built-in VC ( Vibration Compensation). Even when shooting in low-light conditions with a slow shutter speed to render sharpness, Tamron’s acclaimed VC allows for stable handheld camera work, to more fully enjoy the benefits of this high-speed zoom lens.
- Uses special high-grade glass in the three LD elements, three glass molded aspherical lenses, one hybrid aspherical lens and two XR (Extra Refractive Index) glasses, delivering top-of-the-class quality images suited to this high-grade lens. Using a rounded diaphragm, the lens achieves gorgeous blur effects. This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.
- Features Tamron proprietary USD ( Ultrasonic Silent Drive) to power a speedy AF drive together with a continuous manual mechanism.
- This high-speed standard zoom lens has a wide-end focal length of 24mm that expands the photographic area.
- The lens adopts the new technology including the latest optical design, VC ( Vibration Compensation) image stabilization and USD ( Ultrasonic Silent Drive), all in a lighter and more compact package.
- Moisture-resistant construction helps prevent water from penetrating the lens.
