Sorry to resurrect a slightly older thread, but I have had issues too, with timelapse & shutter synching.
I've been doing timelapse for a few years, I used to use my regular bodies, but realised quite quickly that this would kill the shutter a lot earlier than normal use, so why trash a lightly used 7d or T3i, when I could pick up a camera with perfectly adequate resolution that is otherwise 'obselete' for next to nothing and trash that instead.
So, I bought a 10d.
Don't buy a 10d for timelapse. Tricky to find uwa or even wa lenses at a modest price as there is no ef-s mount.
Also the cameras buffer is slow, and is packed solid after half a dozen shots, and that was with a 2gb Sandisk Extreme iii, which is close to, if nothe best performing card for the 10d. As the camera I bought was mint condition, I reckon the counter hadn't been reset and it had just over 4'000 clicks on it. I felt kinda bad about sentancing such a nice camera to the photographic equivalent of Stick Car racing, so I'm actually glad it wasn't that suited anyway.
My girlfriend wants to learn photography, so she now has a near mint 10d to learn on.
Anyway, I digress, so I got a 20d.
On paper, ideal. Much better depth and buffer, and plays nice with bigger and faster cards (the 10d was crippled by its internal buffer, thus the 20d can make much more productive use of faster cards, this time a 4gb 30mb/s Extreme iii)
So i've now done a few tests and find a new, frustrating and odd issue...
I can't get the cam to synch with the remote (far eastern clone) at anything less than 4s intervals.
A bugger, as it worked fine with my 7d...
Here are my settings...
ISO 100 (usually)
Shutter .8s (in the past this was my ideal, just before NR darkframe, and is close to 180 rule at 2s i tervals)
I have tried at a faster shutter, to no avail.
Lenses: Samyang 35mm f1.4 (no chip) Lensbaby composer (no chip)
Shooting jpeg, single frame advance
I just cannot get the camera / remote combo to give me anything quicker than 15 fpm.
I could work with this, but for the 180 effect on exposure duration, 2s in daylight just melts people into a grey blur..
if I go faster, then the motion just isn't as fluid as I would wish.
The point is that I should be able to, and that the remote (which plays nice with my 7d) doesn't work properly with the 20d.
I may have to try a canon genuine timer instead....
