If you are curious about the Canon Mirrorless system, there’s a practical bundle available at Adorama. They offer the Canon M3 with the 18-55mm lens and EF-EOS M lens mount adapter for $599 with free expedited shipping. But you are not done yet. Expand the yellow “Special Offer” segment. The first option there is to add the Canon EVF-DC1 Electronic Viewfinder (for G1 X Mark II, G3X & EOS M3 Cameras) for just $2.58 more. Just press the blue “Add to Bundle” button and then below it the green “Add Bundle to Cart” and proceed as usual.
