Canon 60Da Overview
by putra paulus
Posted: 04/02/2012
Canon has announced the EOS 60Da, a followup to the EOS 20Da model
released way back in 2005,
incorporating improvements made in the many intervening years. Like
that camera, the EOS 60Da is aimed at astronomers, and is closely
related to an existing model: the
Canon EOS 60D.
Beyond the new model number, the most notable difference from the
standard model is a modified infrared cut filter that has greater
transmittance of H-alpha (Hα; 656.28 nanometer wavelength) light than
that of the EOS 60D. According to Canon, this should allow H-alpha
light sensitivity approximately three times higher than that of the EOS
60D.
Translation? Better pictures of reddish, diffuse nebulae...
(Note: While Canon USA's press release seems to imply that the sensor
itself also has improved hydrogen-alpha sensitivity, we see no mention
of this in Canon Japan's press materials, and believe this inference
isn't intentional.)

As with the EOS 20Da before it, note that while the Canon EOS 60Da
can certainly be used for shooting regular pictures as well, they will
tend to have something of a reddish cast, and hence it's not really
recommended to do so. The EOS 60Da makes more sense as a secondary body
to accompany your existing Canon SLR, rather than as your primary body.
The Canon EOS 60Da should go on sale April 2012, with only limited
numbers available from select dealers. Estimated retail pricing is
around US$1,500, around US$400 above list pricing for the standard EOS
60D.
