Think Tank Photo introduces the Sling-O-Matic, the photo industry’s first sling camera bag that can be easily switched to either shoulder. The Sling-O-Matic’s adjustable, fully padded shoulder strap “automatically” slides along a set of rails to change which shoulder the bag can be worn on. This is the innovative solution to the problem inherent with other sling bags: only being designed to wear the sling bag over the same shoulder. With one smooth motion, the Sling-O-Matic can be quickly switched to the opposite shoulder without losing the characteristics that have made sling bags popular among photographers. The Sling-O-Matic series offers three unique bags to choose from, depending on the set of photo gear a photographer needs to carry.

Key Features:
  • Easily switches back and forth to carry over either shoulder
  • Gear access stays on top when Sling-O-Matic is in front
  • Fits a DSLR and a 70-200mm f/2.8 attached, with the lens hood in position 

Gear Profile:

  • Carries a standard DSLR and a 70-200mm f/2.8 attached with lens hood in position, plus 3-5 additional lenses
  • Carries up to a 15.4” laptop in a separate padded compartment
Technical Specifications:
  • Interior Dimensions of photo gear compartment: 11.25” W x 16” H x 5.5” D* (28.5 x 41 x 14 cm*)
  • Interior Dimensions of laptop compartment: 11.25” W x 16” H x 1.5” D ( 28.5 x 41 x 3.5 cm)
  • Exterior Dimensions: 12” W x 17.25” H x 7.5” D (30.5 x 44 x 19 cm)
    *bag flexibility allows expansion to carry some pro size DSLR bodies with a lens attached inside the main compartment.
  • Weight: 2.9–4.0 lbs (1.3–1.8 kg) 


Exterior: For superior water-resistance, all exterior fabric has a durable water-repellant (DWR) coating, while underside of fabric has a polyurethane coating. It also has 1680D ballistic nylon, 420D velocity nylon, YKK® RC Fuse (abrasion resistant) zippers, antique nickel plated metal hardware, nylon webbing, 3-ply bonded nylon thread.

Interior: 210D silver-toned nylon, high-density extruded nylon, removable 210D silver-toned nylon & velex dividers, polyurethane backed velex liner, clear polyurethane mesh pocket (non-PVC), 2x polyurethane coated nylon 210T seam-sealed taffeta rain cover, high-density open & closed cell foam, 3-ply bonded nylon thread.

1 The photo industry's first sling bag that can be easily switched back and forth to either shoulder. Sling-O-Matic's adjustable, fully padded shoulder strap "automatically" slides along a set of rails to change which shoulder the bag can be worn on. With one smooth motion, the Sling-O-Matic can be quickly switched to the opposite shoulder without losing the characteristics that have made sling bags popular among photographers.
2 Gear access always stays on top, when the Sling-O-Matic is in front, no matter which shoulder the bag is carried over.  Part of the challenge of creating a "reversible" sling bag is to make sure that the access door to the photo equipment faces up when the bag is swung forward.  No complex reconfiguration of the Sling-O-Matic is required.  Simply flip the bag over, open it up and start taking great photos!
4 Sling-O-Matic 30 carries up to a 15.4" laptop in a separate padded compartment. Similar to accessing the loaded photo equipment, the zipper for the laptop compartment always faces up when the bag swings in front of the body.
5 Discreetly stylized to avoid obviously appearing like a camera bag.  Going incognito is important when carrying expensive photo equipment.  Like other Think Tank bags, the Sling-O-Matic is all black on the outside so it won't attract too much attention when the equipment is stowed away.
7 Up to a medium sized tripod can be carried on one side using the included tripod straps.  Each Sling-O-Matic includes two fully adjustable straps that attach to small, but secure, fabric loops on either side of the long pocket.  Depending on the size of the tripod legs, one or two of the legs can be inserted into the long pocket for additional stability. 
8 Some small tripods can simply be carried in the long pocket, without using the tripod straps.
6 Long side pocket for carrying a large water bottle or other bulky accessories.
9 Large handles on three sides help to swing the bag around or just carry it in hand.
10 Wide zippered pockets on front, back, and side for carrying a newspaper, airline boarding passes, or other items.
11 Business card pocket on the top for carrying a short stack of business cards.
12 Attach the included "chest strap" for additional stability while walking around.
13 The adjustable side of the chest strap can be used as a waist strap, if preferred.
14 A small pocket on the bottom of the Sling-O-Matic is available for storing any of the removable straps.
15 A selection of padded dividers are included to partition the Sling-O-Matic's interior for different types of gear.
16 A seam-sealed rain cover is included for protecting the Sling-O-Matic and its contents from heavy rain, dust or snow.
Packed Bag

What's in the bag:
The Sling-O-Matic series of bags are designed to have gear stacked within the interior compartment. The top photo shows two pro-size flashes, a 24 - 70 f/2.8 and the 14 - 24 f/2.8. Fold over the flaps and add one divider over the 14 - 24. The bottom photo shows the next layer of gear. A Nikon D700 attached to a 70 - 200 VRII (with the lens hood reversed) and a 105 f/2.8 micro.

Overall Product Rating:     

Exceptional capacity in a slim profile. I have many think tank bags. This is the slimmest one that fits a eos 5d with a grip attached to a 70-200 2.8 is II with the hood reversed, 24-70 2.8, 16-35 2.8 II, 85 1.2 II, 1.4x extender and 580 ex flash. I am sure you can put in one more lens. But I did not want to put in any more due to weight constraints. In addition, I have a gitzo traveler 1541T in the gitzo traveler case attached to the side. All of this weighs 23 Lbs. I plan to use this as a travel transporter in planes. This is a smaller package than my airport international, though heavy on my shoulders. The reason I want to use the sling-o-matic 30 instead of the airport international is because of the heavy use of carry ons in this age of fees for checked in lugague. I will easily be able to store this under my seat and have leg room. The airport international does fit under an airline seat, but does not give me much leg room. I had to do this once when the overheads were full. I would advise not to fill this to capacity if you want to work out of the sling o matic, because it would cause sore shoulders. I plan on using this as a transporter to my destination and then use a maximum of 3 lenses when I want to work out of it. I will update this review once I go on my first trip with this bag in 2 weeks. I have also ordered the harness for the urban disguise to see if I can use it with this bag When I travel on airplanes with a full bag over multiple airports. Using the sling strap might be asking too much of my shoulders. In all fantastic bag, very protective. This is a preliminary review since I had the bag for only two days.

I was looking for something between backpack and regular camera bag. I did even knew that this kind of camera bag exists. I purchased it two days ago and love it. I was surprised how many equipment I could pack in it. Maybe it has a secret double bottom. And lifetime warranty. I hope I do not need it.

When I make any change in my gear bag, it throws me off, I usually can reach in with out looking to grab something. So going to a whole new bag is a nightmare for me...however, I wanted a bag that I could fit everything that I like to take with me, all in one bag. It took a bit of adjusting and moving the adjustable interior panels around, but once I did, well I just love this bag. I have A Canon 7d, with a Really Right stuff l bracket, plus a swivel mount for an "R" strap, + a battery grip, my camera is about as big depth wise as it gets. You have to spread the opening a little extra wide when slipping the camera in and out of the bag, but once it's settled into the bag, it is safe and secure. I have the mounted lens ( varies ) and 3 or 4 different lenses, a flash, a Really Right Stuff Flash frame ( which in my opinion is THEE best one available- it is extremely small and light, works perfectly and stores like it's not even there ) , plus flash batteries, memory cards, R strap, ipad, sometimes, laptop too, and I swear there is still room, in the bag, I slide a monopod in the outside sleeve. it was not my intension to walk around all day with this bag on, with that much stuff, the bag is heavy, but again, I wanted all of my stuff in one wearable bag. It fits that bill for me. Also I love the handles on the outside of the bag, no matter how you reach to grab the bag, there is a handle or strap . Think Tank does not make any junk, so you know the quality is there. I spent a great deal of time shopping on line, looking at specs, how the compartments open, access to everything. Overall review, I love it and I am glad I bought it.

I use this bag to carry my Canon 7D w/batt grip w/17-55 2.8, my 50D w/batt grip w/10-22, 70-200 2.8 IS, and 85mm 1.2, and i still have space for 3 flashes and my pocketwizards. All of the pouches and pockets allow me to carry plenty of extra batteries and cards as well as my netbook. The only problem with it is that when you can carry that much gear the bag can get heavy. Being able to switch shoulders is a huge help towards shoulder fatigue. When you sling the bag around in front of your body it opens extremely easy and doubles as a support for your camera when hand holding a long lens! I could not be happier with this bag.

A couple of weeks ago, I purchased a Sling-O-Matic 30 for an upcoming trip, which I made this past weekend. One of the very best purchase decisions I've made. The bag contained my Nikon D3S with a 28-70mm F2.8; a 28-70mm f2.8; a SB800 flash and battery pack; various accessories; an iPad; magazines; charging cables; etc. Of particular note, the bag fit easily under the aisle seat in front of me on a Southwest plane. I wore the bag while walking nearly ten blocks from Penn Station to my hotel in New York City and was never tired, never had to change shoulders. The bag is a very, very clear winner. Well done Think Tank Photo! Lou Outlaw

If ThinkTank has a fault, it continues to design products without Nikon Products in mind. I'd love to have this bag, but it will not hold a D3 well. Nice to see the overview now states this, but I'd rather have the bag a 1/4 inch larger so it did!

Great bag. It holds a huge amount which can make it heavy. The padding is great so its not bad on your shoulder. It has handles everywhere so its easy to pick up especially from overhead compartments on planes. I also like the document pockets on both sides. The switching feature works fine but I don't use it. Anyways now I got rid of my regular camera backpack and only use this when I bring more gear. Normally I use the Urban Disguise 5.

This is a follow up of my first review of this bag. See "exceptional capacity in a slim profile.." I toook this bag with my 5d with a grip attached to my 70-200 2.8 is II, 24-70 2.8, 16-35 2.8 II, 85 1.2 II and the gitzo 1541T in a traveller bag strapped to the sling-o-matic 30 with me to Hawaii on Hawaiian airlines. The slim profile of this bag reduced my stress about worrying that the bag would be checked in if the overheads were full. This was a big deal. In addition the combined weight of the bag + equipment was 25 lbs. This came in handy on the flight back from Hawaii to SFO. For whatever reason Hawaiian airlines will weight our carry on, for the light back to San Francisco and not the other way around. Their limit for carry on is 25 lbs - it passed. I bought this bag specifically for this. I go to Hawaii every year. In addition I know this bag fits under the seat. As far as weight balance this bag does not do as well. This is even after swapping shoulders. I had 2 sore shoulders. There are 2 ways to handle this : a. Take less equipment. B. Use a luggage cart. I got a luggage cart for the next trip. As far as usability goes, this bag is fantastic to work from. It swings aound real easy and provides a platform to work from and change lenses. So, there you have it fanatastic bag but not perfect. I am trying to add a strap near the top so I can attach the think tank shoulder harness to releive shoulder stress on long hikes/walks/travel transits.

Great bag and I have taken it to Europe and Singapore. I got rid of my Kata backpack as this holds everything and is more usable. It does get very heavy with all the gear. Only thing to add is if there is a small pouch for stuff may be velcroed to the inside would help with some of the smaller photo and travel item. The pockets on the openning is really only good for thin and small things.

The reason for the only three star rating here is because, due to extended wear, the "sling assembly" stitching has begun to come undon and the main carry handle is beginning to rip at the edges, otherwise this is an excellent bag. You have to be really careful to reduce the amount of photo gear you carry, should you decide to carry a laptop. I've carried a MacBook Pro in this case with three Leicas for about a year and now it is time to replace it.

I like the design of this bag and it is verry good build. (sorry for bad english). But i don't like to carry it around when it's fully packed. I'm a strong fella but It really hurts my sholders. I guess it's not made for me. for hiking it's a no-no, i need a bagpack for that. For travel with planes, car, e.a. it's hmmm... dunno, i like a bag with wheels better. But again, the build quality is good/

Great bag that holds a large amount of gear, but not good for use of more than a few hours. Even though you can switch shoulders etc, it really starts to wear down on the wearer. But when I do have day-long assignments, or go out on a hike, I bring a different bag anyhow. The Sling-O-Matic 30 is what I bring with me on assignments and to weddings, and carries the majority of my gear, including a 1D, 50D, 24-70L, 70-200 2.8L, 50 1.4, Sigma 15-30mm, and an external flash (could squeeze a second one too). Another benefit for any other newspaper photographers is that there's a spot for a laptop as well, just keep in mind that it can add a fair bit more to the weight. Otherwise, definitely an excellent bag!

I bought the Sling-O-Matic 30 almost a year ago and have mixed feelings about it. On one hand, it definitely protects my equipment, but from a practical use perspective I have been frustrated with it. I agree with the reviewer about the frustation with the taller Nikon bodies. It's OK if Think Tank designers prefer Canon, but you certainly can design for both. I have a D300 with MB-D10 and it simply doesn't work in this bag when carrying my 15" laptop. I CAN and DO use this bag with my D300 and grip, and even with a RRS L-plate attached, but I have to carry my laptop in a different bag. Another complaint is the lack of useful pockets and storage for smaller items. I have found the flat pockets useful for flat Lumiquest diffusers and roll-up Honl snoots, but not batteries, filters, etc. which is a realy design flaw. I probably would have been happier with the 10 or 20, but I wanted the features and capacity of the 30, but it just doesn't work. I am disappointed with the Sling-O-Matic 30 and have relegated it to storage and transport of my gear, but don't use it for carrying and don't shoot out of it (like I hoped to). Having said all that, I just ordered a Retrospective 20 which will hopefully work better for me carry while shooting. So I haven't yet given up on Think Tank, but the Sling-O-Matic is, in my opinion, a design/execution flop.

Love-hate is my assessment after a fully loaded air trip with only one lay-over. Loaded weight was just under 20 lbs with a 5D, lenses, misc stuff, and Ipad. I was looking for a smaller bag than the large backpack I've been using. My assessment of the sling idea: an ideal torture device. It sounded good in the store empty, but not in airports lugging it. The stuff fits well, and seems well padded and secure. My 16+" Vaio laptop did not fir - fortunately. and I'm not sure the thickness of a regular laptop would not interfere with camera body mounted on a large lens. Other gripes. The carry handle should be a bit wider so as to slide onto the extendable handle of a normal suitcase so you don't have to worry about the bag falling off as you wheel. It seems well made otherwise. It fits perfectly under the seat in front of you when the overhead is full, and equally well in the overhead of the small planes serving secondary air routes. It also looks great, especially next to black suitcases of similar fabric. BUT all that is secondary when you are in horrible pain after a short walk! Any success converting it to a harness?

I have had this bag for a couple of years. I use it to go out to our boat on the weekends. I holds 2 bodies, and 4 of my lenses , a flash, batteries, and extra cards. I can also put in my laptop. Yes it is heavy, but I expect that with the gear I carry. What I have an issue with is the sling strap, I have had a hard time understanding how it is to work. Besides that it is great, and well used.
