FPS/ Shutter actuations
« on: October 18, 2012, 02:55:28 AM »
Hello,

Is there any way to make the Canon 600D burst mode go to le's say 6fps?
I understand that the 7D has the same sensor and the limitation is in the software not the hardware.
Is this true? Please correct me if I'm wrong.

Cheers,

Who says the limit is the software?

A buddy of mine told me, but i don't think he is right...that would be absurd.
I just want to make sure he is wrong.

And how do he knows about that?
The fact that they share the same sensor does not mean they can do the same FPS.
Processor power might be different, mirror assembly can be different...

I think one limit is buffer size. Also 7d probably has a beefier/faster shutter. I can look but doubt there is a way to speed it up.

I've handled a 7d and the clicks sound different too so mechanism isn't the same.

Right, it's not just about the sensor. I don't know specs, but it's safe to say that the 7D likely has a bigger memory buffer to store images. The shutter assembly is likely different, and that's important also. The other part is that the 7D has dual processors whereas the other cameras with the same sensor only have 1 processor.

It's much like 2 cars have the same body, the internals could be entirely different and so one may give you much better performance than the other.

I've always considered shutter mechanism speed to be the cause of FPS for each camera. Memory buffer influences the number of consecutive shot that can be made at max FPS until full. But I've no proof on that only supposing this.
I'm using ML2.3 for photography with:

I can think of a hardware limitation for the 1000D which (i'm counting on my memory now) had a mere 1.5 fps burst. Considering the same shutter and mirror assembly as the 450D, i guess that was something in the FW that prevented a better performance.

Actually no, the 1000D has 3fps burst in JPEG. It's artificially limited to 1.5fps in RAW.

I can't tell if my jpeg fps is faster than raw. It also needs time to save the raw files. Maybe a shorter but faster burst is possible. Doesn't seem very easy though.
