fred 76: This SLR is of no use in astro-photography :
Remote Capture is impossible with it !
That's crazy for such an expensive camera.
Sorry I dropped the "D" !
Tethered shooting is not allowed, and Live View through the computer screen is also not allowed.
This appears to be a last minute decision from Canon's marketing team since these functions were listed in the preliminary specification (as of early oct 2012).
The EOS M should therefore be rebranded as "Powershot M" instead of "EOS M".
This SLR is of no use in astro-photography :
abi170845: There's no bulb setting? I'm a landscapist and bulb hardcore, 100% of the time I bulb my exposures for 10 minutes starting at twilight( if twilight starts at 5:27 a.m, I usually bulb for 10 plus minutes at around 5:20 a.m)
And how about the availability of extra batteries and remote control or cable release?
It should be worth treating such long exposures as the astronomy photographers do, by substracting a "dark" and dividing by a "flat" master images. The noise will drop down dramatically and the vigneting/dust traces will disappear.
It seems that in Bulb mode, you can only select 400 ISO. However it should be possible to remote control the M from the EOS Utilities' Remote Capture tool.
For the batteries, it usually takes a few month (weeks) before a chinese maker supplies a compatible battery.
The µ4/3 sensors are 17.3 mm × 13.0 mm in size compared to the 22.2 mm x 14.5 mm APS-C. This is about 40% less in surface. That's a lot !
For the same number of MPixels, an APS-C will have bigger photosites hence a better sensitivity and less noise.
That's a technological fact.
There is definitely NO REASON to buy that kind of camera because it is FAR TOO MUCH EXPENSIVE.
A G1X will do the job for less, with only advantages :- integrated flash- orientable screen- small size- ability to store RAW pictures- big CMOS sensor (almost same size than a EOS sensor)- only 560 EUR !!!
The only advantage of the M compared to the G1X is the ability to change lenses and to use the EOS Utilities softwares. Is it worth the huge price increase ?
I hope they will sell it bare, without anything (no lens, no flash), just the body.
fred 76: This camera has a big potential for astrophotography. It is light weight, has a short flange to sensor depth, and a decent sensor. But to shoot astrophotos, we need to be able to operate the camera from EOS Utility (or any other software that uses the Canon EOS SDK).
Some questions about the use of the EOS M with EOS Utility:1) will it be possible to do remote shooting?2) will it be possible to get Bulb with very long exposures (say 10 minutes or even more)?3) will it be possible to use the EOS Utility intervalometer?
Last question about modifying this camera :1) is it difficult to open so that we can remove and replace the internal UV/IR cut filters?
... seen on Canon Canada : when using the Bulb mode, only the 400 ISO gain can be used.
Is it also valid when using Remote Capture ?
