Quick assessment: The original Lowepro ProTactic 450 AW (LP36772-PWW) is a large, structured camera backpack designed for two professional DSLRs, a substantial lens collection and a 15-inch laptop. It offers four access points and useful modular attachment options, but at 2.6 kg before loading equipment it is not a lightweight all-day hiking pack. It also should not be confused with the 450 AW II or the current BP 450 AW III.
This guide evaluates what the original 450 AW can carry, which access points are genuinely useful, where it becomes cumbersome, and why some buyers might prefer a newer or smaller model. It is based on Lowepro’s published specifications and the bag’s documented design, not an invented personal field test.

Lowepro publishes these details on its original ProTactic 450 AW product page. The internal measurements are the useful starting point for fitting a camera with a large zoom; the number of lenses stated in product descriptions is not a guarantee because lens hoods, battery grips and dividers change the space available.
Who benefits from the larger 450 design?
The original 450 AW was built for a gear-intensive working photographer. It is easier to justify than a smaller bag when an assignment requires two cameras, several lenses, flashes, cables, batteries and a tripod. The padded rear opening lets you arrange everything before leaving; the top and side doors provide more selective access without unloading the entire compartment.
A smaller everyday camera kit may not need this much structure. If you typically carry one mirrorless body and two modest lenses, the heavier and deeper 450 could be more backpack than you need. Consider the original ProTactic 350 AW or the more compact ProTactic BP 250 AW instead.

Four access points: flexibility versus complexity
Lowepro designed the original ProTactic 450 with a top access opening, two side compartments and a full-length rear door. In a carefully arranged kit, a side opening can make one camera ready faster; top access can suit a mounted telephoto lens. The rear panel is preferable when setting up or reorganizing the full complement of lenses.
The layout only works as intended when the padded divider arrangement matches the access point. If the camera is too far from a door or blocks another compartment, the theoretical convenience disappears. Before packing for an event, check that cameras and lenses can be retrieved without rubbing on unprotected hard edges.
Camera equipment and laptop fit
Lowepro quotes capacity for two pro DSLRs and up to eight lenses/speedlights. That is a manufacturer example, not a universal capacity standard. Two large full-frame bodies with battery grips and long lenses might consume much of the bag. Confirm the actual lens barrel length, mounted hood and tripod collar before buying.
The CradleFit laptop sleeve was marketed for 15-inch notebooks. Today’s 15-inch laptops and 16-inch machines vary by case dimensions, and the 450’s published laptop pocket measures 28.5 × 3 × 37 cm. Compare the physical laptop dimensions with those figures; screen diagonal alone is not sufficient.
Because the exterior measures 34.8 × 27 × 48.8 cm, it may not fit some airline personal-item allowances. If air travel is your priority, measure the packed bag and read our backpack air-travel guide before assuming it will be accepted as a cabin personal item.
Comfort, weight and carrying accessories
The 450 AW uses Lowepro’s ActivZone harness and modular SlipLock attachment system. Padded shoulder straps and body support are useful features, but they do not eliminate the effect of weight: with 2.6 kg of empty bag plus a two-camera kit and accessories, the total load can climb quickly. Carrying comfort depends on torso length, belt adjustment and weight distribution, none of which can be settled by online specifications alone.
Five included modular accessories—a bottle pouch, utility case, tripod cup and two straps—are useful because they let items remain outside the main padded camera area. Load these cautiously: a tall tripod attached to one side can make the pack feel unbalanced. Keep heavier items close to your back and test the full load before a long outing.
Weather resistance: what the AW Cover can and cannot do
The supplied All Weather AW Cover is intended for extra shielding in rain or dusty weather. It does not convert the backpack into a sealed waterproof container. In prolonged rain, straps and exposed areas can get wet, and submersion would be inappropriate for a bag holding cameras. Our waterproof versus water-resistant bags guide explains the difference.
Practical strengths and drawbacks
Reasons to consider it
- More room for two cameras and several lenses than the smaller original 350.
- Four distinct access positions support different shooting workflows.
- Padded modular dividers and a dedicated laptop compartment organize a complicated kit.
- The included tripod and utility attachments reduce the need to fill the main camera area with every accessory.
- The manufacturer’s original measurements remain available for evaluating a used bag.
Reasons to pass
- At 2.6 kg empty, this is heavy for an everyday one-camera setup.
- The nominal 15-inch laptop sleeve does not meet every modern laptop size.
- A bulky loaded bag is inconvenient in crowds or on long hikes.
- Individual side doors may be awkward if interior dividers are not arranged correctly.
- A discontinued-generation bag may have worn zippers, missing modular attachments or compromised weather covering; inspect used-condition listings carefully.
Original 450 AW versus the current 450 AW III
The current ProTactic BP 450 AW III is not simply this bag with a new label. Lowepro publishes 28 L total volume, 2.95 kg weight and 23 × 34.5 × 51 cm exterior measurements for the III. It has revised MaxFit molded dividers, a different ActivZone carrying system, dual bottle pockets, a removable utility belt and laptop storage designed for a 16-inch MacBook Pro.
The original 450 is lighter when empty, but does not have every modern organization feature. The newer bag can be a better match for someone with a 16-inch laptop and an updated modular workflow, while a well-priced original 450 may still suit a photographer whose entire kit fits its actual interior. Compare them as separate generations and check the retailer’s precise product model.
Original 350 AW versus original 450 AW
On the manufacturer’s figures, the 350 AW is 2.0 kg empty with a nominal 13-inch laptop pocket; the 450 AW is 2.6 kg empty with a 15-inch laptop pocket. Both use four access points and adjustable dividers. That extra 0.6 kg may be worthwhile for several large lenses, but it is unnecessary for everyone. Our 350 vs 450 comparison includes an original-model side-by-side table.
Frequently asked questions
Can it hold two cameras with attached lenses?
Lowepro lists a two-pro-DSLR arrangement, including one camera with a 70–200 mm f/2.8 lens attached. Exact fit depends on model size, lens hoods and the divider layout.
Does the original 450 AW have room for a 16-inch laptop?
It was marketed for a 15-inch class laptop. The original sleeve is 28.5 × 3 × 37 cm; check your particular device dimensions instead of assuming a modern 16-inch laptop will fit.
Is the original ProTactic 450 AW waterproof?
No. It comes with a weather cover but is not an immersion-proof or waterproof dry bag.
Verdict: substantial camera capacity, substantial weight
The original ProTactic 450 AW is a sensible choice when you need a large padded two-camera loadout, modular mounts and multiple access options, and you do not mind a heavier empty backpack. It is harder to recommend for a light mirrorless kit or prolonged hiking. Decide based on the dimensions of your real equipment, the condition of the bag and its price compared with the newer III generation.
