The sensor on the Canon T3i is on front of camera body. Does this device require pointing it toward the sensor so it can't be used from behind camera?

It shouldn't. The smart trigger is bluetooth instead of infrared. so your smartphone can trigger the camera from any direction relative to the camera once installed. Works with the same kind of connection as a wireless earpiece for your phone, rather than the with kind of connection for your TV remote

I was curious since I have never tried that before. I just tried it and with the additional brackets that come with it I was able to position the viewfinder directly in front of my eye perfectly. That was tested with a Canon T3i. Your results may vary depending on camera, etc but it worked perfect for me.

yes, but you will not be using your full frame sensor (only a portion of your sensor would be used).

http://www.eos-magazine.com/articles/remotes/canonrc6.html by design, Canon put the remote control sensor in the front area of the camera. i believe all of the canons are like that. if you are shooting from the back, some use wired "http://www.bhphotovideo.com/c/product/164276-REG/Canon_2476A001_Remote_Switch_RS_80N3.html"i just peep my sensor over and trigger it :)

no, the t3i is a physically larger camera body, so the controls will not line up.

In my experience it has to be pointed directly at the unit, it appears to be IR so direct line of sight is required.

This item does not have a "camera" requirement, it is only a "target". Any camera that you point at it will record an image and that image will reveal if the camera in question has a "back focus" or "front focus" problem. If (and this is important) your camera has a "Focus adjustment" (Canon = AF microadjustment, Nikon = AF Fine-Tune, other cameras may vary) then you can shift the focus point forward or back until the target shows a centered focus (in your test picture(s)). If you have multiple lenses, each gets it's own setting (on this camera). If your camera has no option to change Auto Focus range... this item is of no use.Instruction Sheet:spyder.datacolor.com/wp-content/uploads/2012/07/SpyderLensCal_UserGuide_English.pdf This item does not have a "camera" requirement, it is only a "target".

Not familiar with canon models, but if you have a full sized sensor some vignetting will occur. If you have a ds sensor, you shouldn't have a problem.

You can use it on a two-third sensor too. I do. The sides of the image just kisses the edge of the frame (Landscape mode) however, the top and bottom of the frame is cropped so you don't get a complete circle.

No problem with the camera, However, you would have to position the device so that the camera is where you want it.

No, it works from the front and back as long as you point it directly at the camera

It does not have a remote sensor. It does change the feel of the camera (makes it look bigger). Also to use the vertical button the cable that is supplied with the grip has to be installed from the grip to the remote shutter port on the camera. All in all it's not to bad it does what it's designed for. If you install two batteries in it sometimes you get an error message on the camera stating battery is not compatible, all I do is remove the grip and reinstall it and it works fine.

Im not certain exactly what condition you are describing, the camera is a reverse (mirror) image camera, so however you mount it, you will want it to be pointing rearward because its a mirror image. Unless of course you buy a monitor which has a reverse image switch on it, in which case I believe you could mount it facing forward and not have a mirrored image.if you are satisfied with the mirror image, but simply want to change the orientation, such as rotating the picture 90/180/270 degrees, it is relatively easy, though not recommended, to open the camera and rotate the electronics. I'm certain that this would void the warranty, and you would want to be certain that it is water tight.I hope that helps.

I've connected my T2i ( with an adapter.. no lens) to the rear cell without any issues.I would suggest attaching the camera to the scope and and rotating the entire unit until the scope and camera are parallel with the ground, if the scope tilts upwards it's likely that either the gears are worn or the camera is too heavy. Hope this helps.

It's an EF mount, meaning I line it up with the red dot to put it on my T4i. In other words, yes it will work on your T3i and every other Canon DSLR (1D through 700D and T2i through T5i at least). I don't think it would work on the EOS M because that's a mirrorless and has a different mount.

No, its socket is only supported by the 1Dx. There is a flash mount GPS that the lower end newer cameras can use. Not sure if that one is supported by the T3i.

do it right from the 1s time and get the T3i. The APS-C sensor on the 3i is the same like the one on the Sony NEX 3C/C5 . larger censor = better image reviewshttp://www.dpreview.com/products/canon/slrs/canon_eos600d
