I have a Canon 700D (aka Rebel T5i) and will do some shooting on a birthday. Is there a possibility to connect my camera to a TV and make an instant slide show of all the pictures I have taken? Preferably, any wireless connection to the TV.
It's all covered on pages 258-265 of your 700D Instruction Manual. You may use either the supplied standard A/V cable or an optional HDMI cable for high resolution playback. The only way to do it wirelessly would be to use an Eye-Fi card to transfer the images to another device (pp. 311-13 of the Instruction Manual) as they are shot and then play back the images using the other device.
