NiSiMacro Focus Rail NM200s - 360° Rotatable Stable Macro Slide/Macro Adjustment Slide/Macro Focusing Rail for Macro Photography

Only used a few times but it is a good piece of equipment.

Benutze die Schiene für Fotostacking denn nicht jeder hat das geld für eine motorisiert schienebin ganz zufrieden mit der schiene nur weis ich nicht für was die füsschen sein sollen

This is my fourth (and most expensive) macro rail over the years. As you gain experience, you realise the shortcomings of your equipment. My first macro rail (very cheap) moved side-to-side as you cranked it!I'd decided I needed something with accurate markings - not just on the rail, but on the crank. This Nisi fitted the bill.When this rail moves, you can tell it's made with decent materials and precision engineered.BUT - the unsung 'killer feature' is the push-button that disengages the drive - so you can quickly move the camera plate. This isn't just a 'convenience' - it allows you to find the 'Back Point' and 'Front Point' efficiently. This feature alone is worth the extra cost over the cheaper Nisi rail.Top Marks to Nisi - I suspect a macro enthusiast was allowed to design this piece of kit!

I wasn't sure as to prior negative review that arca plate was too big. It works.Main plate mates fine with RRS.The attachment to camera is the one in question. Works with RRS. Tight with Hoage plate but worked.One wheel rotation equals 1mm, good. Wheel is marked with 1/100 increments.It seems that mounted on solid tripod should be best results particularly if considering focus stacking. Not sure how I would use included feet so put them in box. Kit includes camera plate, also not needed by me.Use with live view is nice as with my 7x set up (entire full frame image = about 5mm) there isn't much light to focus. Image is a 28mm reverse attached to 200mm macro via the filter thread.New to focus stacking so no advice as to results with that.A time saver vs trying to move entire setup front and back, ie the threaded focusing wheel.

The clamp's jaws don't open wide enough to accept several of my arca-swiss style plates and lens feet via the normal mounting method. Any plate wider than 38.00mm won't fit. In the attached picture, a lens foot that is 38.50mm wide, won't fit through the fully open jaws. However it can be slid into the clamp via the ends of the clamp if the anti slip safety screws on the underside of the plate/foot are removed.Admittedly it is the third party plates and feet, not the clamp, that deviate from the arca-swiss specs, but an extra 1mm of tolerance in the clamp opening would have been beneficial.Apart from the above problem the rail is sturdy and works well.Check the width of your arca-swiss style plates and feet before purchasing this item.
