edsdk - fast shooting

wgeppert — Wed, 14 Jan 2015 08:46:46 GMT

Hello, I am developing a fashion shooting application and using the edsdk to control the camera. So far so good. In comparision to EOS utility I can' t shoot fast (only every 6 sec.) otherwise I get -device-busy- error. What ist pushing the break in my app? Do I have to initialize different? Even locking the camera doesn't make a difference. How do I setup the camera by edsdk to shoot 6 images per second? best regards

What camera, lens, ISO etc are you using. 6 FPS will require very good light & a fast lens indoors (which I assume you will be).

thanks for the reply.

I need to mention: I know optical factors. The question is not about photography - it is software development. Something makes the camea busy when accessing by edsdk. But eos utility is much faster. What makes the difference?

I know nothing about code etc but could the delay have to do with the software re setting the AF? Have you tried using MF?

Thanks again. Yes, I tied even this with MF and halfway shutter press before shooting. No solution.

Has this fast shooting ever been addressed?

I have the same issue with my application.

I need to shoot at about 3 frames per sec but cant seem to get faster than about 1.5 sec between shots.

I send a trigger to the camera and the image received event in C# doesnt get fired for about 1.2 secs.

ThenI download the image to the SSD over the USB 3.1 bus --- so abou 1.5 sec cycle time -- depending on the image size.

I am shooting in highest res -- using the EOSR5.

I have tried buoth the hardware and software trigger -- same result.

I have used MF and AF -- also attempted to shut down all the image distortion processing.

I can set up the burst mode and gets lots of frames/sec -- but I have no control over this timing.

So I know the camera can do it!
