Really Right Stuff MPR-B STOP BAR overview

  • 1Description

The MPR-B Index Stop Bar is compatible with all Really Right Stuff's multi-purpose rails and camera bars. To use, simply clamp on an Arca-type compatible rail or gimbal head to mark your place or to use as a safety stop.

Additionally, when photographing panoramic shots, it is important to mark your no-parallax point to keep the shot consistent. This is when the index stop comes into play. Once the optical center is determined, the stop bar marks the point, so the set-up can be recreated. The stop bar has a nylon thumb screw, which locks the bar into place, and is it adjustable anywhere on the rail or camera bar.

    Really Right Stuff MPR-B STOP BAR reviews

    MPR-B Index Stop Bar with Thumbscrews is rated 3.5 out of 5 by 2.
    Rated 3 out of 5 by from Mostly Metal, Great if not Bumped Don't get me wrong. This is a useful product. I use these to mark points on my nodal rails and panogimbal head for quick, precise setup in the field. They are well made and mostly serve their relatively low-impact purpose. However, if bumped, they may move, defeating their purpose. This has happened to me carrying plates they've been attached to in my bag. My only complaint is that the screw is made of nylon, not metal. I understand that this is likely a size constraint. In order to incorporate a metal screw, an additional clamp mechanism would have to be incorporated to prevent damage to plates and rails. Using the nylon screw allows the screw to directly contact the rail. The problem with this design, however, is that the grip on the rail/plate is not as secure as it could be. These have occasionally slipped during use, rendering them less useful. I wish there were a slightly larger version of this product with a metal screw clamp mechanism, essentially a tiny, thin version of the clamp on their micro ball head. Such a clamp would provide an extremely reliable indexing bar. I would be willing to pay the greater price. If you don't think they'll be bumped around too much, these should be more than adequate for your work. Just know that they may not hold securely enough for heavy outdoor use and travel.

    Rated 4 out of 5 by from Not bad as a stop bar I bought this as a flange on my lens plate and prevents twisting of the lens. (Nikons lens collar has only one screw mount). I would give five stars if the thumbscrew was not plastic.
