Canon Shutter Actuation App for Mac

[serendipidy]

Cool

The app appears to work fine. I used it on my 7D, 5D2, 5D3 and 1DX. However, since my 1DX is fairly new, I know the exact count from looking at my file name sequence. This app is underestimating by about 1000 shots. However, even the built in shutter count on the 1DX is not reading properly. My real file count is 4400, the app reports around 3500 and the 1DX menu shows <4000 so obviously even the internal count isn't right and that is what the program reads. However, as a general measure it seems to be fairly accurate probably reading the camera correctly but it seems the camera itself doesn't store the data accurately.

Hi,

The cause of your shutter count discrepancy is how Canon's firmware counts actuations. There are two numbers: a non-volatile count and a session (volatile) count (a session is the time interval between power-offs). What we display is the non-volatile count. When you power on the camera the session count is zeroed. It is incremented during the session and added to the non-volatile count when you turn the power off. If power gets cut abruptly, then the camera fails to do a proper shutdown and will not add the session count to the non-volatile count - resulting in "missing" shots.

When you remove the battery the first thing the camera does after detecting that the battery door is open is to shut itself down properly. The time it takes to fully open the door is usually enough for the shutdown. So it's hard to cause an abrupt power cut this way. But when the battery runs too low during shooting, it might not provide enough power for a proper shutdown. Or the easiest way to reproduce this phenomenon is to power the camera with a DC adapter and just pull the plug.

Hope that this clarifies the situation.

Cheers,
Agnes

Hi,

The EOS-M is a heavily crippled camera: it works only in USB mass storage mode. It is not possible to control it via PTP, and thus we can’t get the shutter count.

Curious. Where does the app get the "Owner name" info ? I have captured my name in camera (as Author) but it does not show in the app.

Is it normal/expected/possible that cameras leave the factory with some actuations on them already? Quality assurance testing, maybe? What's your experience?

Yup. I'd actually be worried if my camera arrived without anyone bothering to see if it works! You can't buy a new car with 0 miles on the clock for similar reasons.

This kinda makes sense.

So if I bought refurbished, I should expect the app to report actuations even if the in camera counter says 0? I've always thought the in camera counter was like an odometer in a car but I guess canon can always reset it.

Hi All,

The new version of the app is available. You asked, we added the following cameras: 1D Mark IV, 50D and 550D/Rebel T2i/Kiss X4.

Cheers,

 

[Shakarpix]

Thanks AgnesL! I'll be ordering almost immediately! ;D

I've just updated my version 1.0 to version 1.1 (a free upgrade via the App Store) and it now works like a dream with my 50D.

Thanks ever so Agnes and Laszlo for developing a really useful (and very reasonably priced) application.

Is my shuttercount.com as accurate as this app? Or does this app do more than my shuttercount.com?

Battery door? 1DX what battery door or any other real camera "1D series"???

For those of you who own FoCal (any version), it includes a feature to show you shutter count. It seems like a lot of people don't know about it, so I thought I'd share. Here's the info on it:

Hi iKenndac.
Actually it is more likely true that you can't buy a new car with zero miles because it was delivered to a different dealer, but because you selected skybluepink with aircon and a spare wheel not a tube of gunge it had to be driven by an uncaring delivery oik whose only interest was how fast he could get it to your dealer and get home! Sorry to burst yer bubble on that one!

Cheers, Graham.
