Does this work well with the Canon 70D's screen?

It does. but find an alternative way of keeping it on the lcd screen. After a couple of hours mine kept falling off.

It will, but the features that make this useful are already built into the 70D. You can set your focus point by just touching the screen.

Yes, the Canon ACK-E6AC Adapter Kit will work with the 70D. This adapter simulates the LP-E6 battery which the 70D uses. Also, if the battery grip has a slot for the adapter cord to fit in, then it can probably be used. However, it is extremely rare to need both the adapter and grip at the same time. When using the adapter, I usually have the camera mounted on a tripod. If I need to grab the camera and go, I just keep a few fresh batteries with me. Good Luck!

I use it with my Canon 70D DSLR, so I assume it would work just fine with T4i, or any DSLR in the Canon line.

It works on my t3i/600d, not sure what mount the 70D carries. If same mount, then it should work for FD lenses and your camera.Note that performance is somewhat lackluster with intermediate glass, adjustment for infinity focus is difficult to maintain as glass can freely rotate with movement. Wasn't wonderfully impressed, but it does the job, and for the price and being able to use previously unavailable lenses, I suppose I'd purchase again.

You must have a 15mm rail setup on the 70D of course, but this should work with almost any dslr as it is adjustable both vertically and horizontally. Excellent build Quality and value for the money. I use it with multiple cameras' including my FS700.

Unless Canon has changed their led screen size, it will work great. I use it on a t2i. Great value for the money.

This combination has worked fairly well on my 30D (in direct sunlight). It works quite well on my 70D (even good enough for birds in flight). Link to some images...http://www.pbase.com/jekyll_and_hyde/with_teleconverter

If the screen dimensions are compatible to my Canon T4i then it will work. I have the flip out screen also and in outdoor light this will work great for seeing detail on the screen. I would recommend this very highly.

If your camera will interchange lens, then it will work. Because of the camera body sensor it may have a 1.4-1.6 X magification of your lens . take 70X1.6=112mm lens setting. The lens stailization is with the lens. It works Great I have this lens on my Canon 7D. good alround walkaround lens,although a bit heavy. Clarity is excellent.speed of focus is within most shooting parameters.

I am using it in my Canon 60D and it works fine. If the Canon battery in the 60D is the same as the 70D, seems they would be interchangeable?

It works as advertised for me on my Canon 70D. What do you mean by full functionality?

Yes, this system would be compatible with your Canon 70D. Please note that this lens can only be focused manually.

I used it with a D70S and it worked well. It does not magnify the center of the picture. You have to experiment to determine where in the frame it is looking.

I've been using it on my 70D and had no problem. The camera shows 100% full and Recharge Performance good.

Yes, as long as you pay attention to the connector. The one pictured works with my 70D.

It works on my 70D but with different canon lenses like my 70-200m f/4L, 50mm f/1.4, and 24-70mm f/2.8L. I don't have a 100-300mm lens.
