    Really Right Stuff B150-B-ULT PKG reviews

    Premium Dual Axis Macro Focusing Rail Ultimate Package is rated 3.3 out of 5 by 3.
    Rated 3 out of 5 by from Not up to Par I love RRS and have a ton of their gear. This is the first time I've been less than thrilled with one of their products. Bottom line is there is too much play in the system - but if you tighten things down to eliminate movement, the adjustment screws no longer function. Also, the micro adjustment screws are not nearly as precise as I'd expected -- backlash. So I'm sending these back. I expected so much more.

    Rated 2 out of 5 by from Could be a lot better I love RRS and own a lot of their gear. I had confidence that this rail kit would be up to their standards when I ordered it; unfortunately, it was not. The mechanism that allows the rail to quickly move freely is spring driven so if your payload is too heavy or the tension screw is slightly too tight, the screw skips. Here's the catch: if the tension screw is not tight, the whole thing wiggles left and right. I really tried to make it work.. I mean, I really wanted it to work since it was an international order.. but I ended up returning it and lost money in the process.

    Rated 5 out of 5 by from Super close I used this rail system with the Canon 5:1 macro lens and a Canon 5D. I impressed with it’s preformance and quality. I would recommend it with no reservation. The only issue I had was shooting at a 90 degree straight down. The fine adjustment screw would skip with the weight of the lens and camera. It took very little help to over come this. If one is using this macro set up you have to have a fine adjustment screw. I glad it has this fine threaded adjustment screw vs a course screw.
