Hello,all.Could anyone tell me how to trigger the 5D MarK 2?What kind of way do you use?I once trigger the Canon ixus 100 by mode of relay.I conneted two wires from inner keyboard(shutter) to the apm. It works very ok.Because Canon ixus 100 is very cheap,I can do this way.Is there any efficient way to trigger the camera(5D Mark 2).

These work great. One is a source in Europe and one is in the USA.
You can use an IR trigger to trigger cameras, not sure about the 5D MK 2. Read here.
There is no doubt you can trigger the camera in a number of ways, syncing the trigger for applications where light sources and movement need to be imaged at the same moment, that is another story. Movement in UAV's is a real issue. In many cases you get the Gumby Effect, some call it the Jello Effect when using a CCD or Rolling Shutter CMOS sensor.
I guess it's hard to say what would be appropriate when Zheng never mentioned what he was photographing, or in what conditions.
It is difficult to determine his application with little information. However, the elaborate electronics shown in this forum to trigger conusmer cameas is interesting, Nearly all machine vision cameras have this included with the camera for an external trigger and sync, no need to add any electronics to trigger the camera.
Do you have any links to machine vision cameras comparable to a full frame DSLR and something like a NEX 5? I'm curious to see how they compare in price and other features, and it sounds like you have some in mind.
One more item, prices can range from $400(Off the Shelf) to over $1M dollars for complete design and manufacturing programs. Most of the cameras I either sell or design fall in the $400 to $50,000 range.
Yes, I design and build cameras with single sensors to 75mp, prism cameras to 225mp in RGB, RGB/NIR to 375mp.
Also have COTS(Customizable off the Shelf) cameras. Most Machine & Robotics Vision cameras fall in to this category.
Wavelengths from X-Ray to LWIR(.01nm to 14um)
Full frame(35mm) are easy to design & build, plus there are a number COTS cameras on the market.
Also have 2K & 4K Cinema Cameras, COTS, easy to carry with shoulder harnesses etc.
Also custom & COTS camera lenses, covering from XRay to LWIR. Motorzed Iris, Motorized Focus, Motorized Zoom or any combination.
Combined with our proprietary embedded computer/camera systems, complete autnomous imaging is easily possible. The computer controls all aspects of the camera and the lens. Onboard image processing, therefore no post processing, such as required with Pix4D and other similar software.
Right now we are working on Sense & Avoid systems to meet new FAA regs. A minimum of 220 degrees, up to 360 degree continuous imaging. Low Light & High Dynamic Range CMOS sensors for night flying and also for direct flights in to the Sun.
Just some of the items we work on.
Nex5 is a consumer camera, not robust enough for anything I get involved in. I wouldn't waste my money.
The issue you will have is syncing the trigger to your application. You should get a machine vision camera for this. A decent model can now be purchase for under $500US. Consumer cameras are not made for this, period.
