Sometime after the release of their first Macro Focusing Rail the Sunwayfoto MFR-150 Wormdrive Macro Focusing Rail with Lever Clamp, Sunwayfoto has introduced a sister model with almost only difference the quick release clamp type integrated on the carriage.
The newer Sunwayfoto MFR-150S is equipped with a classic Screw Knob QR clamp instead of the Lever Release Clamp. Thus the S at the end of the model name. Otherwise there are no noticeable differences between the two.
