Think Tank Photo Lens Changer 50 - Compact Lens Case for 16-35mm

In this review the Think Tank Photo Lens Changer 50 is presented as a small, purpose-built lens case aimed at photographers who need fast access to a single wide-angle zoom. The bottom line: it is for shooters who carry a 16-35mm f/2.8 or 17-40mm f/4 with the hood attached and want one-handed retrieval on a belt system. The case's best selling point is its wide-mouth, quick-access design paired with compatibility with Think Tank modular belts, making it a practical everyday carry solution for event, travel, and run-and-gun photographers.

Key Features

• Fits popular wide-angle zooms: Designed to hold a 16-35mm f/2.8 or 17-40mm f/4 with the lens hood attached so photographers do not need to remove the hood between shots.
• Rotate or lock attachment: The belt interface can be rotated or locked in place on a belt, giving flexible carry orientation during active shooting.
• Wide-mouth opening: A large top opening enables quick one-handed access to the lens, which speeds lens changes in fast-paced situations.
• Modular belt compatibility: Attaches to any Think Tank Photo modular belt or belt pack, making it easy to integrate with an existing carry system.
• Compact, light construction: With external dimensions of 7.5 in H x 5.0 in diameter and a weight of 0.3 lbs, it adds minimal bulk while protecting the lens.
• Secure internal fit: Internal dimensions of 7.3 in H x 4.5 in diameter provide a snug interior for a single wide-angle zoom with hood attached.

Who It's For

This case is ideal for wedding, street, and travel photographers who prefer to carry a single wide-angle zoom on their belt for quick transitions. It fits lenses like the 16-35mm f/2.8 and 17-40mm f/4 with hoods attached, so anyone who uses those lenses regularly will appreciate the convenience.

Photographers who need to carry multiple large telephotos, mirrorless kits with many lenses, or who do not use a modular belt system should look elsewhere; this product is focused on compact, single-lens access rather than large-capacity protection or shoulder-bag carry.

Pros & Cons

Pros

• Very quick one-handed access due to the wide-mouth opening, saving time during fast shoots.
• Designed to accept a lens with the hood attached, avoiding the need to remove the hood between shots.
• Lightweight and compact so it does not add significant bulk to a belt setup.
• Rotating or locking belt interface offers versatile carry orientation on Think Tank modular belts.

Cons

• Limited capacity: it only fits a single wide-angle zoom with hood and is not suitable for larger or multiple lenses.
• Requires a Think Tank modular belt or belt pack (sold separately) to attach, so additional purchase may be needed.

Our Verdict

The Think Tank Photo Lens Changer 50 is a narrowly focused but well-executed solution for photographers who carry a single wide-angle zoom and need instant access.

If you need multi-lens capacity or non-belt carry, consider a larger case.
