OP/TECH USA Super Pro Strap B – Padded Neoprene Camera Strap with Quick Disconnects | Fits Medium-Format Cameras with Posts (Hasselblad, Mamiya, Bronica) | Non-Slip, Adjustable – Made in USA

There are a couple of bad reviews for this strap suggesting that "Strap B" doesn't fit the Mamiya RB67, so right off the bat let's clear that up: it fits just fine. It took me a few minutes to figure it out, but it works. I'm going to add some photos to show how it's done on the RZ67, which uses the exact same lugs as the RB67. The main thing to remember is that the metal clip end is NOT one piece (even though it kind of looks like that at first glance). It's two pieces with a spring tension holding them together. By pressing the lug against the inside of the clip, you can force those two section to separate, widening the hole and allowing the lug to slide right into place. Then you need to ensure that no part of the metal clip is hung up on the outside portion of the lug, If it is, press back on it toward the camera until the whole unit has cleared that circular outer portion of the lug. Then slide the black plastic piece down so that it's wedged underneath those two little tabs on the back of the metal clip. That plastic wedge ensures that the two halves of the clip can never separate by accident. If you're still having trouble figuring it out, the packaging does suggest going to the website at optechusa. com where they have a video explaining how it's done. Now, as far as the strap itself is concerned, it's pretty great. I haven't ever had a strap on this camera until now, so I can't really compare with other straps or the claimed 50% perceived weight reduction. I can definitely say that it makes a world of difference compared to handholding it, and it is surprisingly comfortable when wearing around the neck. The padding soft and thick, and the inside has an anti-slip surface that works well when it's slung over a shoulder. It's designed to stretch a small amount, acting as sort of a shock absorber, and I'm sure that's part of how they figure the apparent weight reduction. There's a spine along the top that keeps the stretchy part from stretching TOO far, which keeps it from turning into a spring-loaded projectile in extreme cases. The foam portion of the strap can be removed via some heavy duty clips, so if you have multiple cameras you can just buy the ends from the company and attach the foam part to whatever camera you're using at the moment. Or you can swap out the foam part of the strap for another one. I'm not sure why you'd do that, but you can do it if you want. Overall it's a great strap, well worth the money if you're currently handholding a beast like this.

Got for my mamiya m645...fits n works great...only issue is always have to unhook n untwist the lower straps...one side is always twisted while other side is straight...has me saying hmmm...very comfortable for such a heavy camera...its a keeper!

I bought this to go with my Mamiya RB67 and it works perfectly. The strap feels comfortable and holds all the weight of the camera with the lens and prism very well. I did have a little trouble attaching it to the camera and you really have to make sure the clips lock into place but after that you're good to go.

I bought this strap so i could more easily use my RB67 for portraits on location. I find working off a tripod in these situations to just further slow and already cumbersome process. This strap keeps the camera safe around my neck and the padding alleviates some of that famous RB67 weight. Add in the super reasonable price (ive seen just stap lugs for as much) and you are getting a heck of a bargain

TL;DR: With slight coaxing and some force, you can get the strap (style B) to fit on the Mamiya 645 Super's right-side strap lug. The only issue is that the strap bumps up against the winding knob on the film back, but it's not a major one. ---------------------------------- I bought a Mamiya 645 Super recently and the strap they included did not fit on it. I looked around for a while and this strap was the closest replacement I could find (Style B). I needed to coax the spring steel portion of the strap to go further out when I was pressing it onto the right side of the Super's strap lugs and it fit okay; though, it does bump up against the film back's winding knob a little bit. This was a better solution for me than buying an OG strap for ~$200 and is more secure than some other alternatives I tried (the foam part of the strap is also pretty comfortable, so that's great).

I use this strap for my Mamiya 645E, and the clips fit the lugs properly and securely. I was skeptical of the fact that the strap does have buckles, but after receiving it, you can feel that those buckles are made with VERY strong plastic and shouldn’t give out. The neck pad seemed odd at first with the small grip beads on the inside, but after using it, it was comfortable and helped make sure the strap didn’t move around. Overall, a very good strap for those looking to carry your medium format film cameras around.

Great product! I've been testing the Type B strap with my RB67 and so far I have no problems. I love the fact it has little soft plastic stubs in back of the foam strap to keep it stable when slung around my neck or shoulder. I can understand why some people thought type b doesn't fit onto a Mamiya RB67. The instructions that came with the strap weren't the best. Although, OpTech did a wonderful job explaining how to add the strap onto you camera via YouTube. Here's a link to the Video: [...] . I highly recommend this buy if you plan on lugging around something like a RB67!

I was looking for a good strap for my old and heavy (4.5 lbs) Bronica S2A, and it was rather difficult as there are not many options. Also, OP/TECH USA does not list S2A in their list of cameras that this trap can be used for. I just received OP/TECH USA Super Pro Strap (Design B) and confirm that it works well for my Bronica S2A. Please note that there are older (or newer) Bronica cameras that have a different lug. Check the pictures I uploaded; if you have the same lug on your Bronica, then the Design B strap should work for you.

Having acquired a Contax 645 Medium format camera I realised I needed a strong durable camera strap that would fit the Contax camera lugs securely without the anxiety of any issues supporting such a unique camera. Having read many reviews and forums in reality Op/Tech Super Pro B Strap met all my expectations. The strap can be purchased with the A or B Strap and as described by many photographers the B strap connectors were a perfect fir for the Contax 645 with lockable sliding mechanism at each connector that reinforces the attachments giving you more peace of mind where your camera support is concerned. The strap support is made well, wide and sufficiently padded to demand the name of Super "Pro" and initially feels comfortable although I have yet take a lengthy walkabout with it. So I will report back about my experience. The great feature is that you can detach the connector straps from the shoulder pad and connect the appropriate Op/Tech connectors for any other camera whilst taking advantage of a quality support system. I would recommend this strap to any semi pro/pro photographer who wishes to support their Contax 645 kit or any other camera the B straps fit using a well constructed product from an established manufacturer. Before you purchase make sure you check if your camera connectors support the A or B Strap connectors

I bought this to use with my Mamiya Rb67 and it is very good. The pad on the neck makes it comfortable and the camera feels secure. It has held up very well with time!

A little pricey for a strap but it is quite comfortable and has a versatile length range. Most importantly the "Design B" fits my Mamiya 645 securely as advertised.

Very happy with this purchase. I like the way it attaches to the Mamiya RZ67. It's a little bit difficult to move the plastic bits out of the way to get it on at first, but once everything is attached, everything feels very secure, especially with the plastic bits back in place.
