Unlocking the 50mm Lens: Simple Fixes That Transform Your Photos

A 50mm lens often gets dismissed as plain and uninspiring. It sits between wide and telephoto, which makes it easy to overlook, but if you know how to use it, it can bring surprising depth and atmosphere to your images.

Coming to you from Martin Castein, this practical video shows how to unlock the potential of the 50mm lens. Castein begins with one of the most common mistakes—tilting the camera slightly downward when shooting portraits. That tiny angle can make a photo feel off, even if you can’t pinpoint why. He points out that fixing it in editing with Lightroom’s transform tool only distorts the image, stretching heads or bending verticals in ways that never quite look right. The cleaner solution is to keep the sensor flat to the subject. This advice may sound simple, but it’s one of those subtle technical shifts that can dramatically improve consistency in portraits.

Castein goes further by demonstrating how changing your shooting height can transform a scene with a 50mm. At eye level, the lens can feel predictable. Drop lower, sometimes as low as your waist or even the ground, and the perspective changes completely. Roads widen, foregrounds stretch, and depth increases. He stresses that you need to exaggerate more than you would with a 35mm, because the 50mm’s field of view doesn’t naturally give that dramatic pull. He also notes the advantage of mirrorless cameras here, letting you move the camera lower without pressing your face to the ground. In one example, kneeling and keeping the sensor flat turned an otherwise ordinary street shot into a frame with balance and scale.

Another technique he highlights is moving in close—sometimes uncomfortably close. Staying at eye level but shortening the distance to the subject, while keeping the background pushed far behind, creates a look that starts to feel cinematic. It mimics some of the compression of an 85mm but with its own character. He points out that using a 50mm forces you to move more, teaching lessons about distance, composition, and background control in ways other focal lengths don’t. This hands-on approach can lead to more variety than switching between a 35mm and 85mm, where you might be tempted to stay static and let the glass do the work.

Castein also shares how he uses these same principles in the studio. The focus there is on keeping the camera at eye height with a flat sensor, creating clean, repeatable, and controlled results. He explains why, if he had to use only one lens, it would be the 50mm. It’s versatile enough for both outdoor and indoor work, while teaching discipline in composition and perspective.
