I've since used it for all sorts of odd jobs outside its intended studio use, including sometimes as a makeshift tripod for my 50D DSLR. I've had it over a year, in and out of the ocean, and it is still as strong and rugged as when it was new. For those of you wondering how well it will hold up in the studio, I have no doubt that it will outlive you.
It should be noted that it is big and heavy, and it is not easy to bend the flex arm. I assume this is what gives it its strength to hold up whatever it is that needs to be help up, be it lighting, a DSLR or whatever odd job you find for it.
I thought it would be a great idea to mount to my headboard for reading or watching movies at night before going to bed, but ran into several issues with this flex arm. But, depending on your intended use for this flex arm, these may well be PROs.
- The first is that it is SO heavy that it can sag under its own weight if not using strictly in a vertical manner.
- When purchasing, 21" seemed like a lot of length, but because its strength is in vertical placement, it is too short to create arches to support horizontal weight.
- to get a comfortable viewing distance from an iPad, the flex arm was mounted high up on a vertical corner post to compensate for some sagging. Unfortunately, this places the iPad directly overhead.
- the finished exterior metal "wraps" around a core which could "unwind" by bending / flexing the arm. The tripod ball mount could only tilt so much, so I had to bend the arm like in the picture. Causes the arm to lose strength and sag.
- Is hard to get a bend radius of anything greater than maybe 160 degrees, you probably could do it, but might risk a kink or split in the wrapping.
This flex arm's strength is in its ability to support a lot of vertical weight, however your mileage may vary and it could work better for your application.
I use this for adding an additional light or flash off my tripod for macro photography and it works well for that purpose.
The only flaw I see here is, that all by itself, it can't be mounted to the accessory 3/8-inch female connection on my tripod. The Flex Arm has a 1/4-20 external thread on one end to mount your light, flash, or other accessory; but there is a internal 3/8-16 thread on the other end, which cannot connect to the similar threaded accessory socket on the tripod. You will need a stud (3/8-16 to 3/8-16) in order to connect to the tripod. While these are readily available, I think Manfrotto should have included this with the Flex Arm. It would have raised the price only slighty (if at all) and would have alleviated me the cost of discovery and having to order it separately.
I bought this based on the information that it can hold 1.1 LBs - figuring this would hold a speedlight and not be TOO difficult to twist around.
It can definitely hold a speedlight - I'd imagine it can even hold a DSLR (But I'm not about to try it!) - the thing is, and I'm not sure if it's a good thing or not, the thing is REALLY tough and a bit hard to bend (it needs some force - you'll need 2 hands to bend it). This is both a good thing (it won't bend on it's own!) but a negative if you need to do anything more than slight bends, or need to quickly adjust the angle.
One end has a standard stud-end for a Superclamp (with a 3/8" threaded hole, so you can attach it on top of a lightstand tip). The other end has a threaded 1/4" tip (to attach something like a wireless trigger for a flash).
The great thing about this is that while it's heavy, it gives some great flexibility (no pun intended). While you can always superclamp a flash to a railing, you're somewhat limited on it's angle/direction. This lets you superclamp a flash to a railing and position it EXACTLY how you need it.. angled, straight up, straight down, bend around, etc.. Sometimes the length is a bit too much (at close to 2 feet, you sometimes wish it were just a few inches). It's not the lightest thing to carry (superclamp + arm = 2 lbs), but compared to a lightstand and ballhead, it's much nicer.
I've been a bit mixed on it.. I like the extra flexibility it gives me, the light-weight (in comparison to a lightstand) and small size.. but on the opposite, wish it were a bit shorter and more flexible. It's one of those things you just can't win on, so I'll give it the benefit of the doubt and recommend it. It's the best option out there that I've found, it's sturdy/secure and does its job.
