(Above) Was my first image of my Canon T3i fitted with a Letus Hawk View Finder. Yes it fits quite nicely, and they make it in the proper aspect ratio for the 3:2 LCD screen. What I didn't have was the riser for a battery grip. Here's a gallery (below) from reader HD-Tography showing you the fit and the fashion of the Letus Hawk Aluminum ViewFinder, on the new Canon T3i, with Small Oval BlueStar EyePiece, on Gini Rails offset with a bit of Easom, with the cheap Shoulder Support. Sweet example of many of the items covered in this blog and looks pretty solid.
[Ok guys, this is more of an example of the Letus Hawk ViewFinder with Battery grip riser adapter on T3i, so please don't start submitting your rigs. We'll save that for another time...]
