Sunwayfoto MFR-150S overview

  • 1Description

The Macro Focusing Rail with Screw-Knob Clamp from Sunwayfoto gives you the ability to precisely adjust your camera fore-or-aft when shooting macro photography. The clamp at the top is Arca-type compatible and locks down with a screw-knob. The focusing rail itself has a double-dovetail mount and will fit most Arca-type clamps on the market.

The Macro Focusing rail has both a ratchet handle, for fast and quick adjustments, and a thumb-screw knob along with engraved index marks on the side of the rail for fine adjustments. The CNC machined T6061 aluminum rail holds a maximum weight capacity of 15.4 lb, but may hold less weight once the angle of the rail is changed.

The Type III black anodized aluminum is scuff and scratch resistant and the finish is also resistant against corrosion. In addition, two focusing rails can be stacked for dual axis adjustments (fore-or-aft and lateral). Located on the bottom of the plate are two safety stop screws to prevent any accidental pulling or falling out of the rail when a clamp is partially open.

    Sunwayfoto MFR-150S reviews

    Macro Focusing Rail with Screw-Knob Clamp is rated 4.1 out of 5 by 11.
    Rated 5 out of 5 by from impressive quality for the price This is a great macro rail for the price. It's got a very simple mechanism with no real play in the tolerances between the moving parts that results in smooth camera movement. The rail is very light and has a low profile so it doesn't take up much room at all. There's nothing I can really fault with the design. While it's obvious that the handle introduces a fair amount of wobble due to the off-centre rotation, the wobble is largely from the tripod and head and is only noticeable if you were to try and move the rail from one end to the other quite fast. For focus stacking, this shouldn't be an issue and if so you can always use the thumb screw on the other end.

    Rated 4 out of 5 by from Solid rail for the money Prices are all over the place for focusing rails, so I did a lot of homework.� Others in this price range and lower $� are too flimzy.� For macro, stability is the name of the game and this rail provides that plus a little longer focus range than most others. There is some play when changing directions, but that does not affect the stacking work flow once you get started.� Will work best on an Arca base. Alternatively there are two 3/8" holes for mounting, but they are offset to accomodate the center worm bolt.� Using these provides less than optimal stabilty. Buys this or spend a couple hundred $ more.

    Rated 4 out of 5 by from Quality affordable focusing rail This is a well made, affordable focus rail. The only reason I did not give it 5-stars is because it would be handy to be able to release the block from the screw to be able to move it from one end to the other quickly without turning the screw. Screw moves smoothly, though. Takes some effort, as I know would be the case with any focus rail, to learn how much movement is needed for a given focal length is object distance to maximize what you're trying to do.

    Rated 3 out of 5 by from Great This piece is awesome great value the only problem with this company is that anything but the aluminum is subpar this item the screws had rusted before I even opened the box I have never seen something rust before it was even opened . It was a little frustrating but Price reflects quality.

    Rated 3 out of 5 by from Quality Control Issue with Screw Knob Hitting Crank Shaft The primary issue with this MFR-150S model is the Screw Knob attached to the clamp, which is too long and consequently hits against the Hand Crank, preventing the clamp and the mounted camera from traveling the specified/advertised 106mm (4.17") Adjustment Range. Because the Screw Knob is too long and hits against the Hand Crank, you will indeed lose at least 10mm of Adjustment Range with the MFR-150s--a significant amount. The MFR-150 model, which uses a lever clamp conveniently attached to the side of the clamp that does not come into contact with the Hand Crank, does not suffer from the above issue, and thus, it has the full 106mm Adjustment Range advertised in the manufacturer's specifications. The other issue I noticed with the macro rail is that the indicator pin on my unit was slightly misaligned. However, the misalignment was easily corrected by just carefully pushing it in its hole, as it is a removable pin, given that the manufacturer did not seal it in its hole, which is also puzzling to me. Apart from the above two issues, this macro rail is very well made, with excellent precision. The sliding rail or worm rail on my unit is aligned correctly and runs very very smoothly. Note that because of the area Swiss plate, you may be able to compensate for the loss of 10mm by sliding the entire piece up/down, while it is mounted on a ball head arca-Swiss mount. Nonetheless, you can do the same with the MFR-150 model, utilizing the full 106mm, as specified. In other words, the arca-Swiss mount on either model enables a Total Adjustment Range of 220mm (8.66"). However, with the MFR-150S and its oversized, poorly-placed Screw Knob, you will have a Total Adjustment Range of 210mm, instead of the specified 220mm. This MFR-150S model is okay. I would recommend you buy the MFR-150 if you want the more versatile, as-advertised model of the macro rail.

    Rated 2 out of 5 by from not so good the rail but when i start turning the�handle�the camera base start to go left and right while i'm turning and it is not because of my hand movement. it seems the�lead screw rod is�bent which causing the imprecise movements.� Over all the rails is well belt and solid.

    Rated 5 out of 5 by from exactly as requred Looks well made, fits snugly into my Acratech ballhead, and works smoothly. I like the adjustment from both ends. Right now I am using it with an Olympus Air for macro-scientific work and it is exactly as required.
