OP/Tech, arnés Dual de Estados Unidos

Compré esta correa para usarla al mismo tiempo con dos "ganchos" tipo spider (pero no unos tan caros) pues mis cámaras son bastante pesadas y aunque la correa se siente muy bien hecha, no quiero cargarle todo el peso de mi equipo a unos ganchitos de plástico. Al usar ambos sistemas me aseguro de tener un respaldo en caso de que falle ya sea el gancho o la correa y al estar trabajando la cámara que no estoy usando no baila por todos lados y el peso lo cargo en la cintura y no en los hombros.

widely adjustable and makes it possible to carry two heavey cameras for hours.I particularly like that it doesn't tie up the tripod mount hole.

Tenía una correa de esta marca y estaba muy contento con ella, ahora necesitaba un arnés para llevar dos cámaras y al ver la marca y el precio no lo dudé, y mi elección ha sido correcta, por su relación calidad precio sobresaliente, y porque cumple con creces lo que promete, por poner un pero el enganche que queda bajo el brazo es un poco engorroso de usar, pero una vez puesto las cámaras quedan muy bien sujetas y la espalda no se resiente del peso de dos cuerpos con objetivo y flash, totalmente recomendable.Además los acabados de OP/TECH son de calidad y robustos y en caso de querer usar la correa de la misma marca solo hay que desenganchar el arnés y enganchar la correa, excelente !!!

I had been using the Op/Tech Dual Harness for 3 years with mixed feelings about it. But recently I made some upgrades to it that make it a great harness for carrying one or two cameras.I like to carry two cameras while doing nature photography involving butterflies, birds, wildflowers and other wildlife. I typically use the Canon 7D Mark II with 100-400mm f/4.5-5.6L II IS lens and a Canon 7D with the 100mm f2.8L IS macro or Canon 24-105 f/4L IS lens. I often use a tripod with a gimbal or ball for either wildlife or macro work so all my lenses are equipped with Arca-Swiss style mounts. The Arca-Swiss mounts allows you to quickly mount and balance your camera setup on the tripod head, and it can also you to balance it upside down on a camera strap..The Op/Tech system gives me the ability to quickly switch between straps based on the shooting situation, so every camera I own has the basic Op/Tech 3/8" system connector attached, which when not in use serve as a handle for carrying the camera. I have been using this standard mounting arrangement with the Dual Harness, with mixed feelings. Using the standard camera strap connectors mounted on the top of the camera is awkward when you have a telephoto lens or a macro lens with a flash attached. When walking or bend down, they hang down and swing around wildly, so you have to be careful if you have heavy equipment like I do. The arrangement also requires that the straps between the camera and the harness have to be long enough so you can pull the camera up to eye level, about 4" longer than if the strap is mounted on the bottom of the camera.About a month ago, I started thinking about how to improve my setup. I already owned a Kirk photo safety strap that included an Arca-Swiss clamp that I liked to use when I only carried one lens. The strap allows the camera to hang upside down near my waste, balanced so that it doesn't swing so much when I walk and is much more comfortable to carry. But it didn't work when I tried to carry a second camera attached to a second strap. My solution was to remove the clamp from the Kirk strap and use the system connectors that came with the Op/Tech Dual Harness to make a small strap that holds the Kirk Arca-Swiss clamp. I can now attach any of my lenses or cameras that already had Arca-Swiss mounts to the harness, and the harness can be easily moved from side-to-side. Needing a second Arca-Swiss strap clamp, I bought a "Neewer® Aluminum Screw Knob Clamp Arca Swiss Compatible Mini Quick Release Clamp with Hot Shoe Mount for QR Plate (38mm)" for under $20 from Amazon; I like it even better than the one from Kirk.and have another one on order.I also decided to use a small S-biner in the setup so that I can easily clip the strap/clamp to my belt or belt loop so that when I bend over, the cameras don't swing forward. Along the way, I learned that the Dual Harness is much more comfortable if worn loosely. After loosing it up, I am able slip it on quickly over my head without unbuckling it and can comfortably wear it with either one or two cameras. Lastly, if you wear binoculars, like I do, I highly recommend using the Op/Tech Bino/Cam Harness (Elastic Version). It works great and fits over the Dual Harness while keeping your binoculars close to your chest.The attached photo the straps I built with the Kirk Photo (top) and the Neewer Arca-Swiss style clamps. Use and location of the S-biner is optional..

Pues básicamente la idea es buena, cuando te pones las dos cámaras vas cómodo y las sujeciones son buenas y consistentes. El problema surge al disparar una cámara. Al quitar peso de un lado, la otra cámara tira de él y lo desplaza completamente, con lo que por un lado corres el riesgo de darle un golpe, y por otro es muy incómodo, ya que si estás cambiando continuamente de una a otra, acabas con el cuello rozado. A pesar de que el material es suave, el rozamiento durante varias horas acaba siendo bastante molesto. Por otro lado me gusta la sujeción de dos correas para la cámara, la blackrapid se coge solo en un punto, lo que la hace más inestable, y además pierdes la opción de llevar puesta la zapata para el trípode, o un minitrípode, que yo uso muchísimo. Me gusta mucho también que puedas soltar cuando lo necesites una de las cámaras, para usar en momentos puntuales de forma remota por ejemplo.Al final, le pongo una nota media porque por el precio que tiene creo que se puede arreglar fácilmente ese defecto de forma casera, poniendo unas correas en los laterales, o si usas un cinturón Lowepro o similar para transportar el equipo, puedes alargar sus correas hasta hacer que lleguen al cinturón y así te sirve de tirantes y de paso resuelves el problema de la estabilidad del arnés. Lo que hice yo es coger las correas que me sobran de las bolsas del cinturón Lowepro S&F, las cuales no uso, y llevárselas al zapatero, pedirle que las corte a la medida y colocar dos por delante y una por detrás. El zapatero las cose sin ningún problema. De esta forma aprovechamos las cintas no usadas con sus hebillas de sujeción para algo, y a mi modo de ver es un sistema perfecto.Hice este invento porque no he encontrado el sistema perfecto para llevar dos cámaras y todo el equipo a mi gusto. Las correas blackrapid no me convencían porque me hacen llevar la cámara boca abajo y enganchadas por un único punto, y he preferido hacer un poco de bricolaje, ya que ni pagando una barbaridad he encontrado algo que se adapte a mis necesidades.

I almost always shoot with a pair of cameras because I can have a very wide focal range at my instant disposal with a fast f/stop in my mid-range zoom (17-55mm f/2.8 IS), excellent IQ throughout the range (from 17-55mm to 70-200mm f/4L IS) and very fast and accurate autofocus. IMO, the two camera system is far superior to using a wide focal range lens such as 18-200mm with its inherrent slower aperture, slower and less accurate auto-focus and lower image quality.The only problem with using two cameras is how to efficiently carry these two rigs and, of course, the extra weight this system involves.I made the transition from using a pair of Canon OEM straps (which tangled too much) to the OPTECH Reporter Strap. The Reporter Strap kept the two cameras when used without flashes from tangling but, had two issues about which I am not fond:1. The weight of the two cameras was around my neck and when working with relatively heavy lenses caused my neck to ache after a long day of shooting.2. I had problems when using a flash on each camera (in bounce mode with a Joe Demb Flash Diffuser Pro attached). The problem was that the lower camera's reflector would tangle with the upper camera.The Dual Harness solves both of these problems.1. It distributes the weight of the two camera/lens/flash packages across my shoulders which relieves the pressure on my neck. I am no longer sore at the end of a long day carrying two cameras.2. I can carry each camera equipped with a flash and the reflector / diffuser will not tangle.The way the straps are arranged, it is easy to shoot with either camera.The quick releases of the Dual Harness allow me to disconnect a camera for use on a tripod and to quickly reattach the camera when I take it off the tripod.I can use the dual harness with a single camera if I desire.Since I already had an OPTECH Reporter Strap, I occasionally carry a third camera/lens on that strap. These three cameras do not tangle. The quick release clamps for the Dual Harness are compatible with the quick release clamps of the Reporter Strap which allows me to switch around the cameras in any way I wish to carry them.The Dual harness is a lightweight and relatively inexpensive solution to carrying two or more cameras in the field.I have added a inexpensive carabiner clamp (not the expensive mountain climbing models) to the adjustment straps on each side of my photo vest. Securing each camera strap with a clamp, I prevent the cameras from swinging from side to side when I run or climb.When I am in a crowd, I can walk with a hand on each camera for security purposes. I can also place the dual harness beneath my photo vest which provides additional security from theft and a bit of protection from rain or blowing dust.
