Review on 📸 SUNWAYFOTO MFR-150S Wormdrive Macro Rail with Arca / RRS Compatible Clamp for Enhanced Precision Focus by Justin Kautzman

SUNWAYFOTO MFR-150S has quality control issues. The main issue with this MFR-150S model is the overly long screw knob attached to the clamp and therefore the handle, preventing the clamp and mounted camera from moving within the advertised/advertised adjustment range of 106mm (4.17in). move. MFR-150 is a significant amount. The MFR-150 model, which uses a lever clamp conveniently mounted on the side of the clamp not touching the grip, may not suffer from the above issue and therefore may have the full 106mm adjustment range specified by the manufacturer becomes. To do this, it is enough to insert it carefully in the hole, since it is a removable pin, since the manufacturer did not seal it in the hole, which also confuses me. Aside from the two issues above, this macro rail is very well made. , with excellent accuracy. The guide or worm guide on my device is correctly aligned and runs very smoothly. Note that due to the Arca-Swiss plate, you can compensate for the 10mm loss by sliding the entire part up/down while mounted on the Arca-Swiss mount. However, you can do the same with the MFR-150 using all 106mm as directed. In other words, the Arca-Swiss mount on both models offers a total adjustment range of 220mm (8.66 inches). However, with the MFR-150S and its oversized, poorly placed screw knob, the total adjustment range is 210mm. , instead of the listed 220 mm. It's worth noting that OEC Camera Accessories is offering a pretty good deal of 10% off for 3 or more items, so I only paid $89.95 for this MFR-150S model. If OEC had not offered this promotion I would have returned this model and chose the MFR-150 or Manfrotto model instead. This MFR-150S model is fine. I would recommend purchasing the MFR-150 if you want a more versatile macro rail model as advertised. .
