Periscope Lens vs. Telephoto Lens: A Closer Look

Welcome to Blackview blog. Hope the guide helps.

Both periscope and telephoto lenses serve the purpose of capturing distant subjects, but they employ different optical techniques to achieve this.

Telephoto Lens

• Traditional Approach: A telephoto lens is essentially a longer focal length lens attached to the camera body.
• Physical Size: To achieve higher magnification, telephoto lenses tend to be physically larger, protruding from the camera body.
• Zoom Capability: Typically offers 2x to 3x optical zoom.
• Image Quality: Generally produces good image quality, but can be affected by camera shake at higher zoom levels. Extending reading: Can camera Apps improve photo quality?

Periscope Lens

• Innovative Design: A periscope lens uses a series of mirrors and prisms to bend light at a 90-degree angle, allowing for a longer focal length without increasing the camera's thickness.
• Compact Design: This design enables smartphones to achieve higher zoom levels without sacrificing overall size.
• Zoom Capability: Offers significantly higher zoom capabilities, often reaching 5x, 10x, or even higher optical zoom levels.
• Image Quality: Due to the complex optical system, periscope lenses can potentially introduce more image distortion or color fringing compared to traditional telephoto lenses. However, advancements in technology have significantly reduced these issues.

Which is Better?

Periscope Lens: Ideal for smartphones where space is limited and high zoom capabilities are desired. Offers better versatility for capturing distant subjects.

Telephoto Lens: Suitable for cameras with more room for lens size and where extreme zoom levels are not essential.

In conclusion, both periscope and telephoto lenses have their strengths and weaknesses. The best choice depends on the specific needs and priorities of the photographer or smartphone user. While periscope lenses offer impressive zoom capabilities in a compact form factor, telephoto lenses might provide slightly better image quality in certain conditions.
