NEEWER 4-Way Macro Focusing Rail Slider with Quick Release Plate, 1/4”-20 Thread for Macro Photography and Close-Up Shooting, Compatible with Canon Nikon Fujifilm Sony DSLR Mirrorless Camera

I am impressed with this. It's solid build and works well. It feels like a precision-made product. I have this mounted on a copy stand and it holds a heavy mirrorless full-frame camera and lens. The adjustment knobs work smoothly and evenly. Good grips on the knobs. I especially like the Arca-Swiss mount that it comes with (including a plate) as all my cameras have Arca-Swiss plates attached, so it was easy to put them on.IMPORTANT: It also comes with a smaller 3/8" screw adapter for additional adaptability to copy stands (which tend to have the smaller screw diameters rather than the 1/4" "tripod" screw sizes.) Oddly, there is no information on this on the product description, even though I found this to be very important, since I would have been unable to attach it to my copy stand mount!All in all, this was a very solidly made product at a good price. I would recommend it.

Sehr gute Haptik. Wertige Qualität.Sehr genaue Einstellmechanik.

The media could not be loaded.  I do a lot of macro photography and I have always carried around a large slider. However, with macro photography, this isn’t necessary. You are so close to your subject, the slightest movement is drastic. This is the perfect solution for that. The mechanics on it are well made and the thumbscrews work very smoothly and accurately. It's stable enough that the shutter itself does not cause enough movement to blur your image. The camera sits comfortably and rigidly on the slider.The issue is that this rail when used with high-magnification macro lenses results in a very short field of focus for images. This issue is further exacerbated when you add macro extension tubes to get even higher magnification. The result is the user needs to take a series of photos and merge them to get a useful depth of field. It would make an excellent small rail and a very useful and reliable tool.Although it is very compact, it has high rigidity and looks and feels good with a sense of precision and luxury. This is a much more expensive option as there are a few others on the market. But with that premium price comes a well-made piece of kit. I have high hopes for its longevity. The assembly of the screw drive mechanism is spot on with no backlash whatsoever. The movement is extremely smooth, something you would not expect in a product costing so little. When you look at the price of this compared to a high-end, small slider, it’s more affordable.I am using a Fujifilm camera with an accessory battery holder, weighing in at 3 lb 4 oz, which the macro focusing rail supported with no problem. I'm not sure how it would perform with a heavier camera/lens combo. However, It does appear to be able to hold and focus a heavier choice. I'm sure you can find many macro-focusing rails costing much more than this unit, but quality-wise, this is near the top.Overall a very compact and well-made slider. It offers smooth operation and I think the cost, although slightly high, is very worth it considering its premium nature. If you are after something that can offer more freedom to your macro Lens shoots, this is a great option. Highly recommend.Hope this review helps.

購入以前の本商品説明の予想を超える精密で良い作りです。アルミ製のツマミを回せば、前後左右にスムースにスライドできます。動きは柔らか過ぎず、固過ぎないので丁度良い感じです。添付写真のように、前後左右にスライドしてもガタツキは無く安定性に不安は特に感じません。マクロ撮影の必需品になりました。
