How does it look with the square on the track?
Well, I did see a Nikon D5200 with Klappdisplay.Wie on the two photos, fit two of these DSLRs side by side. However, only when the folding displays are not open. At least at a. In the photos, the Nikon and a zoom microphone is mounted.
Have fun with the rail. You will have it pleasure :)
