The Backer Capper is a single-handed rear lens cap swapping system for professional photographers and videographers.

Who we are and our story:

Ted (the dude typing this) and Zack are the guys behind camarush, a reseller of helmet cameras and accessories.  

One day on vacation in Oregon, I was taking a time-lapse of the sunset on the ocean with my GoPro mounted to a camalapse panning accessory, while at the same time, some scenic shots with my DSLR (specifically a Canon 7D) to pass the time.  All of a sudden, a deer jumped out of the woods about 300 yards away.  What an awesome opportunity to take a shot of this deer with the golden hour here and an incredible backdrop!

Unfortunately for me, I had a 17mm lens on my camera body, because I was taking some panoramic shots.  Quickly, I tried to change to my 200mm lens, which was in my sling bag. It had just rained and I felt like I couldn't put the body down on the ground, or else mud and debris might ruin my Canon.  I ended up strangely juggling both of my lenses and body at the same time until all lens caps were in their proper place and the correct lens was on my DSLR. By the time all of this happened, the deer had been spooked away (most likely by my loud, self-depreciating cursing while attempting the lens change).  

I spent some time that night thinking about how I could have changed my lens faster.  Buy a second camera?  Have a tripod always on hand?  Have an assistant accompany me everywhere I go?  My wife and pocket book would probably not appreciate that!

I found myself wanting a system to help me change my lenses quickly many times over the next few weeks.  I filmed a wedding and found myself in the juggling predicament many times, I photographed my kids on the playground and wanted to change lenses in the heat of the moment to capture different shots, I even found I wanted something while working in the studio.

One of many brainstorming drawings:

After some thinking and refinement, and brainstorming with my buddy Zack, we finally had something that worked.... and worked surprisingly well!

Enter, the Backer Capper:

The Backer Capper is a rear lens cap swapping system for DSLR cameras. The Backer Capper is made to assist photographers, videographers, and cinematographers that have multiple lenses and a single camera base.  

With the Backer Capper attached to your belt, backpack strap or slingbag strap, you can swap rear camera lens caps with one hand while leaving your other hand firmly grasping your camera base at all times.  In addition, the Backer Capper makes lens swapping faster, allowing you more opportunities to capture the perfect shot!

The Backer Capper system is lightweight, unobtrusive, and perfectly integrates into your current lens collection by conveniently replacing your current rear lens caps.  No more misplacing your lens caps, the Backer Capper holds firm with super-strong magnets so you always know where that rogue lens cap is!  Have more than 2 lenses?  We will be selling additional rear lens caps apart from the base system.  In fact, you can pledge one of the packages that contains multiple rear lens caps on the right side of this page!


The Backer Capper system consists of:

- A base that attaches to belts and backpack straps with a hook-and-loop strap.  We include a short and long strap to accommodate various sizes of belts and bags.  The base contains a Neodymium magnet which secures the rear lens cap.

- Two rear lens caps (please select the appropriate Canon or Nikon lens brand package) with Neodymium magnet and locking circular teeth, making it easy to twist your cap on or off of your camera lens.

* Currently, the Canon version of the Backer Capper is compatible with all EF and EF-S lens mounts.

* The Nikon version of the Backer Capper is compatible with all F-mount and AI lenses.

What will the funding go toward?

With the money raised from the KickStarter project, we will be able to primarily pay for the molds to make the body and cap pieces of the Backer Capper.  The molds themselves come to about $18,000.  The additional money will go towards the additional parts, which include the Neodymium magnets, hook-and-loop straps, and even the packaging, all in bulk.

We currently have a printout of the Backer Capper from a 3D printer, as well as CAD drawings.  The 3D printouts work great, but are expensive and time consuming to make 1-by-1.  Keep in mind that the final product will be in black to match your current lenses.

FAQ:

What can the Backer Capper base connect to?  The Backer Capper base can connect to a belt on your pants, a backpack strap, or a slingbag strap.  The body comes with a long hook-and-loop strap (Velcro) and a short strap.  This gives you a number of options on where to place the body of your Backer Capper.

What types of lenses does the Backer Capper support?  Depending on the package you purchase, you can use the Backer Capper caps with Canon EF and EF-S type mounts (which can be found on most modern Canon's including the 5D II, 5D III, 7D, 60D, T3i, T2i, XS, Mark IV, etc), or with Nikon F-mount and AI lenses (which is on all of Nikon's SLRs since 1977).  Lenses for other brands, such as Sony, Pentax, Olympus, Panasonic, and Minolta, will follow if the project is ultimately successful, probably around beginning of 2013.

Will the magnet erase my memory cards if they come in contact with each other?  No, absolutely not.  Magnets only affected the old floppy disks that are not around any more.  Fortunately, most modern storage devices, such as SD and CF cards, are immune to magnetic fields.

Why not just use a camera strap?  For one, as a videographer by trade, I dislike using a camera strap, often mounting to monopods or tripods during the hustle and bustle of the day.  The combination of a strap and a support device never works out in terms of "eloquence".  Secondly, the problem of the camera swinging and swaying loosely around, and steadying the base still puts the camera in danger and is still hard to control with only 2 hands available to change the lens caps.

Why the heck did you call it the Backer Capper?  We did think long and hard over this topic.... probably a little too long.  We wanted a name that represented what the device does, and being catchy at the same time.  An unused domain name helped as well!  It's not easy coming up with a name for a "single-handed rear lens cap swapping device"!  After many tries and catchy names, we thought a fun name like the Backer Capper fit the device well... and now you can't get the name out of your head, can you? ;-P
