We already got a few hints about the Canon EOS R3 specifications. Now another source…
A faked EOS-M with builtin EVF via dpreview forum. Attention: not the real camera!!!
Canon is well known for hiding their intentions. Back when they launched the EOS-M they said that there is actually no need for a mirrorless camera to have an electronic viewfinder. A new source told us the truth: Back when the EOS-M was launched Canon simply had not the necessarily mature tech to offer an external viewfinder for the EOS-M. But Canon is right now developing a new EOS-M camera with built-in viewfinder. Design is a lot close to the current EOS-M but it has a EVF in the corner like the Fuji X-E1 and Sony NEX-6. Definitely no hybrid OVF/EVF, but a “classic” electronic EVF will be used. Unlike rumors posted elsewhere the camera is not hitting stores in Spring but much later (second half of the 2013).
EOS-M with built-in EVF
Keeps the modern look design of the EOS-M. (no retro style)
Hit the stores in late 2013.
