Photo How To

Do you know how many photographs have been captured with each of your cameras? If not you're setting yourself up for a potential disaster. That because the shutter in all cameras has a limited lifespan, varying from one model to another. And if this critical component fails unexpectedly, you'll be left holding an expensive brick in your hands.

Shutter count is also a key consideration when buying or selling used cameras so that no unfortunate surprises arise. In this important video from our friends at the Be More, Do More, Have More channel  you'll learn how shutter count works, see ratings for different camera models, and understand what happens when your camera's shutter fails.

Some photographers merely estimate shutter activations based upon usage, but the only reliable determination involves checking shutter count yourself. Today's instructor Shawn explains the simple steps, and we strongly recommend following his advice for the reasons mentioned above. The last thing you want is for your camera to fail when traveling far from home—and buying a dud that's on its last legs is equally disappointing.

Shawn explains his goal for today's "crucial" episode like this: "We explain the difference between mechanical and electronic shutters, how different cameras from Sony, Canon and Nikon compare, and what you should consider when buying a used camera.

At some point during Shaw's thorough discussion of the rationale behind this important task, you're likely think to think to yourself, "OK, I understand the why, so walk me through the how." And that's exactly what you'll learn to do in the final four minutes of the video.

We bet that once you're done watching you'll grab your favorite camera(s) and check the shutter count per Shaw's directions so you'll know exactly where you stand and what to expect over time.

The Be More, Do More, Have More YouTube channel features an array of maintenance lessons for cameras, lenses, and important photo accessories, so be sure to take a look.

The prevuous episode we shared demonstrates another essential task; namely how to keep memory cards in top shape and prevent losing your photographs before disaster strikes.
