BlackRapid Blackline II Double Dual Camera Harness review

One of my favorite things about owning an interchangeable lens system is that I can simply swap over lenses when I need to shoot wider, more zoomed-in, or macro and close-up depending on the specific subject matter I’m shooting and what I’m trying to achieve creatively. While superzoom lenses such as 18-300mm exist and bring many focal length options into a single lens, they simply don’t cut it for professionals who need both razor-sharp glass and super-fast apertures too.

When taking photos of fast-paced events, sports, or weddings however you rarely have the time to switch your lenses and that’s where a double camera harness can be a game-changer. Important aspects to look for in a good dual camera harness are first and foremost security - you want to be able to trust that your pride and joy aren’t suddenly going to go crashing into the ground. Secondly, there's comfort: if you’re shooting for a whole day with two heavy cameras loaded up, you’ll need decent padding to save your shoulders.

I recently got hold of both BlackRapid’s Double Breathe and Blackline II dual camera harnesses to test them out. On face value they look very similar - they’re both dual camera harnesses that allow you to carry two systems with different lenses attached, making them a good fit for weddings and events. The Blackline II however is a third more expensive, so I was keen to put it through its paces and find out if it’s really 33% better!

Features

I’ve recently reviewed BlackRapid’s Sport Breathe, Blackline I and Double Breathe camera straps, and following suit the Blackline II harness uses the exact same mounting system that I’ve raved about in those other reviews.

It uses a ConnectR and FastenR system to secure your camera to a metal carabiner, this is then secured with a spring-loaded metal piece on the carabiner, and the LockStar Gate is clipped shut to stop it from being accidentally opened - the LockStar Gate can also only be closed in place with the carabiner fully secured and locked down for added security, you do this for both cameras on either side of you. Many of these security features are patented too, so you'll only find them on BlackRapid products.

For even more peace of mind, the Blackline II comes with two safety tethers which can be lashed to each carabiner and then to the strap lug on your camera for another point of camera and a failsafe should the main connection fail, though in our testing everything felt totally rock-solid and we never felt like it would be needed, though it’s nice to have nonetheless.

The camera straps on your left and right are both height adjustable so you can get them hanging precisely where you need them to be within easy grasp which you need to quickly grab one and start shooting. Unlike the Double Breathe harness however, there’s no Slim model, though it has to be said the shoulder pads are already a little slimmer than the Double Breathe and its padding is softer, so perhaps this isn’t needed as much here.

As with the Sport Breathe, Blackline I, and Double Breathe that I’ve previously reviewed, the Blackline II has front and rear bumpers on both left and right straps. These can be adjusted with just one hand to limit or expand the area of travel the carabiner with your attached camera can travel along.

The rear bumper acts as a good backstop to stop it moving too far back out of reach, while the front bumper is great for those times you need to lean forward to adjust a lightstand or bend over to pick something up, as the front bumper can be slid down to prevent your camera from coming hurtling forward.

Performance

The Blackline II put in a solid performance by being constructed from high-quality materials and parts patented by BlackRapid. The FR-5 FastenR is metal but nylon coated for a premium feel and has a 3mm thick rubber disc to help you add just the right amount of tension when screwing it into your camera’s tripod mount port or lens foot. The metal carabiner feels high quality too and screws down to secure it in place, with the LockStar II gate then shutting to keep it from opening accidentally and keeping your kit safe.

One big difference between the Blackline II and the Double Breathe is that, as the name suggests, it has an all-black design. The Double Breathe has a bright white logo on the front right shoulder pad and a shiny metal buckle on the back too, whereas the Blackline II is dressed more like a ninja with all-black plastic buckles and a blacked-out rubber logo on the front too. This makes it much more nondescript and makes it easier to blend in, whether you’re wearing a tuxedo at a wedding, or just want to keep a low profile while shooting street photography.

Another noticeable upgrade from the Double Breathe is the Blackline II has slightly smaller yet more comfortable padding and larger ventilation holes too for ‘ultra’ breathability. I found this to be notably more comfortable as it molded to the contours of my shoulders a little better.

Both the back and chest straps have an elasticated piece of material in them so they move with your body a little and there’s some give which increases comfort. When using mirrorless camera bodies loaded up with lightweight primes or small zoom lenses you hardly notice you’re wearing it as the strain is on your shoulders rather than your neck. However, load them up with heavier DSLRs and big telephoto lenses and you’ll inevitably start to feel the strain a bit sooner.

We had full faith that the Blackline II could handle the weight of whatever we could throw at it. It’s a solid bit of kit with sturdy metal carabiners and attachment points that give you plenty of peace of mind. The carabiners also glide like butter over the nylon straps so you can effortlessly raise your camera up to eye level to take a shot and never get in the way.

Verdict

Alongside this harness, I’ve recently reviewed BlackRapid’s Sport Breathe and Blackline I slings as well as the Double Breathe Harness, and while I’ve been thoroughly impressed with all four products, in my opinion, this is the one to go for. It has a fully blacked-out design which makes it more nondescript and better padding too.

The padded shoulders are softer and also a little smaller than the Double Breathe, so this will potentially be a better fit for women and people of smaller stature without the need for a slim model (like the Double Breathe). Plus, it shares many of the great features of the other straps I’ve mentioned, such as the FastenR and LockStar Gate to keep your camera secured to each strap, in addition to an extra safety strap and bumpers to limit the travel of your camera.

Okay, it might not have the bougie style of a leather (or faux leather) strap, but it prioritizes substance over style with this reliable and solid harness, and for what it’s worth I think the all-black design looks pretty good! The shoulder pads can also be separated and you can use just one as a cross-body sling for those times when you just want to shoot with one camera which adds to its value too.
