Pixel 10 vs Galaxy A57: Zoom & Size
The Pixel 10 and Galaxy A57 differ sharply in zoom and size: the Pixel 10 offers a dedicated 5x periscope telephoto lens (up to 30x digital zoom), while the Galaxy A57 has no telephoto camera and relies on 10x digital zoom from its main sensor. Physically, the Pixel 10 is more compact (about 152.8 x 71.9 x 8.6 mm, ~186 g) compared to the Galaxy A57 (roughly 164.4 x 77.9 x 8.2 mm, ~213 g). This article explains exactly how those differences play out in daily use, what the specs mean, and which phone suits different needs.
Background: Where Each Phone Sits
The Pixel 10 is Google’s 2025 flagship, expected to launch in August 2025 with the Tensor G5 chip. It continues the Pixel line’s focus on computational photography, with a 50MP main sensor, a 48MP ultrawide, and a 48MP 5x periscope telephoto. The Galaxy A57 is Samsung’s mid-range 2025 model (launched March 2025), part of the Galaxy A5x series. It has a 50MP main camera, an 8MP ultrawide, and a 5MP macro sensor—no telephoto lens at all. The A57’s “zoom” is purely digital cropping from the main sensor.
Zoom: Optical vs Digital
Optical zoom uses glass lenses to magnify before the light hits the sensor, so image quality stays high. Digital zoom crops the image and enlarges the remaining pixels, which reduces detail. The Pixel 10’s 5x periscope lens is optical—it physically extends the light path inside the phone. The Galaxy A57 has no telephoto lens, so its 2x and 10x zoom options are digital crops. In practice, the Pixel 10’s 5x photos are sharp enough to print, while the A57’s 5x (digital) looks soft and pixelated. The Pixel 10 also uses Google’s Super Res Zoom AI to enhance digital zoom up to 30x, though results degrade beyond 15x. The A57’s 10x digital zoom is usable only in bright light with a steady hand.
Size and Build: Dimensions Compared
The Pixel 10 is noticeably smaller and lighter. Here are the approximate dimensions (based on leaks and typical specs):
- Pixel 10: 152.8 x 71.9 x 8.6 mm, 186 g
- Galaxy A57: 164.4 x 77.9 x 8.2 mm, 213 g
The Pixel 10 is easier to use one-handed and fits in smaller pockets. The A57’s larger body accommodates a bigger 5,000 mAh battery (vs. the Pixel 10’s ~4,700 mAh). Both have aluminum frames, but the Pixel 10 uses Gorilla Glass Victus 2 on the front, while the A57 uses Gorilla Glass 7 (a newer, but not necessarily stronger, glass). The A57 is slightly thicker but not by much—0.4 mm.
Camera System: What the Zoom Actually Delivers
Beyond zoom, the camera systems differ in sensor quality and processing. The Pixel 10’s 50MP main sensor (Samsung GNV) captures more light, and its 48MP ultrawide is far superior to the A57’s 8MP ultrawide. The Pixel 10’s telephoto has a 1/2.55-inch sensor with f/2.6 aperture, which works well in low light. The A57’s main sensor is a 50MP ISOCELL GN5, but its digital zoom at 2x is just a crop of the center 12.5MP—acceptable for social media, but not for large prints. The A57’s 5MP macro lens is not a zoom substitute; it’s for close-ups only.
How to Choose: Zoom Needs vs. Budget
Your choice depends on how much you value telephoto shots. Consider these factors:
- If you photograph distant subjects (wildlife, concerts, sports), the Pixel 10’s 5x optical zoom is essential. The A57’s 10x digital zoom will disappoint.
- If you mostly shoot people and landscapes, the A57’s main camera is fine, and you save money.
- If you want a compact phone, the Pixel 10’s smaller size is a plus.
- If you need long battery life, the A57’s larger battery and less power-hungry chip (Exynos 1580) may last longer.
Price is a major factor: the Pixel 10 starts around $999, while the A57 is about $499. That $500 difference buys the telephoto lens, better ultrawide, and faster updates.
Common Problems and Misconceptions
A common misconception is that “10x zoom” on the A57 is comparable to the Pixel 10’s 5x. It isn’t—the A57’s 10x is a 2x crop of a 5x digital crop, so it’s very soft. Another issue: the Pixel 10’s 30x zoom is often called “Space Zoom” (a marketing term), but it’s still digital and can produce blurry results without a tripod. On the A57, users often complain that the 2x zoom (which is a digital crop) is not as sharp as the main lens. Also, neither phone has a dedicated macro lens on the Pixel 10, so close-ups are handled by the ultrawide, which is better than the A57’s 5MP macro.
Alternatives to Consider
If you want a telephoto zoom but not the Pixel 10’s price, consider the Pixel 8a (has a 2x optical zoom via a 48MP main sensor crop) or the Galaxy A56 (no telephoto either). The Samsung Galaxy S24 FE has a 3x optical zoom and costs less than the Pixel 10. For a mid-range with periscope zoom, the Xiaomi 14T Pro offers a 5x optical, but it’s not available everywhere. If you prioritize size, the Pixel 10 is one of the smallest flagships with a periscope lens.
Frequently Asked Questions
Is the Galaxy A57’s 10x zoom any good?
No, it’s a digital zoom that crops the 50MP main sensor. In good light, you’ll get a usable but soft image for social media. In low light, it’s often blurry and noisy.
Does the Pixel 10 have a macro mode?
Yes, but it uses the ultrawide lens with autofocus, not a dedicated macro lens. It can focus as close as about 3 cm, which is better than the A57’s 5MP macro in most cases.
Which phone is better for one-handed use?
The Pixel 10 is significantly smaller and lighter (152.8 mm vs 164.4 mm height, 186 g vs 213 g). It’s much easier to use with one hand.
Can I use the Galaxy A57’s zoom for moon shots?
No, the 10x digital zoom will produce a blurry white blob. The Pixel 10’s 30x zoom can capture a recognizable moon, but it’s still AI-enhanced and not a true optical image.
Does the Pixel 10 have a bigger battery than the A57?
No, the A57 has a 5,000 mAh battery, while the Pixel 10 has about 4,700 mAh. However, the Pixel 10’s Tensor G5 is more efficient, so battery life may be similar.
Is the Pixel 10 worth the extra money over the A57?
If you value camera zoom, display quality (the Pixel 10 has a 120Hz LTPO OLED vs. the A57’s 120Hz Super AMOLED), and faster software updates, yes. If you just need a basic phone with a decent camera, the A57 is a better value.
