On the main switch of EOS RT (the last image above), there is a gear marked as RT. At RT setting, when the shutter button is half-pressed, the RT camera gets everything ready except shutter releasing. The only thing to do by the the next half-way pressing is to fire the shutter and gains the 'RT' effect (actually with 8 ms lag).
|The RT body comes with three booklets, including 2 for EOS 630 (Part and 2). |
The RT booklet has only 12 pages in English for RT.
I guess, RT is most similar to 630 among the 600 series.
I post here the RT manual section of 12 pages in English here. It explains the extra functions on RT.
EOS RT is not the first model in Canon EOS family (read my article on EOS 650), but it is said that, with higher significance, it is the first and only SLT camera in EOS family. BTW, the first SLT body sold on market should be Canon Pellix/Pellix QL, which were launched in 1965/1966 and are manual focus camera with a light meter powered by 1.35v button battery.
Canon produced three models of grips for this camera.
In a review on Sony SLT 55 body on June 5, 2011, I wrote: 'SLT' (Sony's Latest Tech) is not new, RT used the same kind in 1989. SLT launched by Sony is all about marketing (your money), not the tech (similar to computer CPUs, 286, 386, 486, ...2-core, 4-core...). D-camera without any mirror has been developed because it's easier to split d-signal than the light, making a real fast and quiet body.
