Anamorphic lenses can transform iPhone footage into stunning cinematic visuals by enhancing the aspect ratio and producing signature lens flares. Whether you’re an aspiring filmmaker or a content creator, an anamorphic lens will give your videos a professional, widescreen look. In this guide, we’ll cover how to use an anamorphic lens on an iPhone, the best lens options, and how to achieve the perfect anamorphic aesthetic.

How Do You Use an Anamorphic Lens on iPhone?

Using an anamorphic lens on an iPhone is straightforward, but requires proper setup. Here’s a step-by-step guide:

1. Attach the Lens: Securely mount an anamorphic lens onto your iPhone using a compatible lens mount or case.

2. Use a Camera App: The default iPhone camera app doesn’t support anamorphic de-squeezing, so use Blackmagic Camera (free) or other professional apps.

3. Enable De-Squeeze Mode: Adjust the aspect ratio to 2.4:1 or 2.76:1 to remove distortion.

4. Adjust Focus & Exposure: Set focus manually to get sharp results, especially in low light.

5. Experiment with Lighting: Utilize natural light or light sources to enhance the anamorphic streak effects.

What is the Best Anamorphic Lens for iPhone?

Choosing the right anamorphic lens depends on the desired aspect ratio and cinematic effect. Two great options are:

• Freewell 1.33x Anamorphic Lens – Ideal for creating a 2.4:1 aspect ratio, perfect for standard cinematic compositions.

• Freewell 1.55x Anamorphic Lens – Produces a more dramatic 2.76:1 aspect ratio for an ultra-wide film look.

Both lenses provide high-quality glass elements and are optimized for iPhone filmmaking.

Is 1.33x or 1.55x Anamorphic Better?

• 1.33x Anamorphic:

  • Creates a 2.4:1 aspect ratio

  • Balanced between cinematic and standard widescreen

  • Suitable for general filmmaking and vlogging

• 1.55x Anamorphic:

  • Expands footage to a 2.76:1 ultra-wide format

  • Provides a more dramatic and immersive feel

  • Best for high-end cinematic projects

Choosing between them depends on your preferred aspect ratio and shooting style.

How to Change the Aspect Ratio of an Anamorphic Lens on iPhone?

Since anamorphic lenses compress the image, you need to de-squeeze it using an app like Blackmagic Camera:

1. Open Blackmagic Camera and select your anamorphic lens option.

2. Go to settings and enable the appropriate de-squeeze option (1.33x or 1.55x).

3. Export footage in 2.4:1 or 2.76:1 aspect ratios for correct playback.

What is Anamorphic Streak Color?

Anamorphic lenses create horizontal light streaks when capturing bright light sources. The streak color depends on the lens coating:

• Blue Streak: Classic Hollywood-style sci-fi and action film look.

• Gold Streak: Warm tones ideal for sunsets and golden-hour shooting.

• Neutral Streak: Minimal color influence for a natural aesthetic.

Freewell offers all three streak options to customize your footage based on your creative vision.
