Excerpt: Got as a second plate for my 504HD so I could keep one plate on each of my main cameras at all times. Not much to say - it does its job well, and the length helps keep the camera sturdy. Came with extra mounting screws for both 1/4" and 3/8".
Pros: Comes With Spare Parts, Easy To Use, Professional Quality
Excerpt: Used with Sony PMW-EX3 and PMW-200 Fits perfectly with Manfrotto fluid head 504HD Compared to the original plate coming with the 504HD tripod head, this 504PLONG does not have a spring-loaded pin. But this is not an issue.
Pros: Easy To Use, Highly Compatible, Lightweight, Professional Quality
Excerpt: Works great with the C300, the longer plate lets you slide back and forth depending on the lens you're using. It connects to a manifrotto tripod, which is not overpowered by the camera weight.
Pros: Easy To Use, Lightweight, Professional Quality
Excerpt: Marked it down because the pin on the plate that keeps the camera from pivoting was made of brass and held in place by a leaf spring. On this one the pin is made of plastic and there is no spring. Easy to pop in an out but also easy to lose.
