The X300 Pro, the flagship model from the Chinese smartphone maker, features a prominent camera module developed in partnership with German optics brand Zeiss. Meanwhile, the iPhone 17 Pro Max remains Vietnam’s most popular premium smartphone, highly regarded for its balanced and consistent image quality.
Apple’s latest iPhone introduces a major upgrade to its telephoto lens, increasing the resolution from 12 megapixels to 48 megapixels, with a 100 mm f/2.8 focal length. It offers 4x optical zoom instead of 5x from the previous model, though Apple claims users can achieve up to 8x optical zoom through its Fusion sensor. The wide (26 mm) and ultra-wide (13 mm) lenses are also 48 megapixels each.
Vivo promotes the X300 Pro as the “king of telephoto cameras,” equipped with an 85 mm (3.5x zoom) f/2.67 lens coated with Zeiss T* and officially certified by Zeiss. It also features a 1/1.4-inch HPB sensor, co-developed with Samsung, offering a resolution of 200 megapixels.









For portraits at 4x zoom, the two phones differ notably in color tone: the iPhone renders warmer, yellowish skin tones, while the Vivo delivers more natural results with higher sharpness and realistic background blur.
The X300 Pro also shows focal length values instead of zoom levels, giving users a professional camera-like experience. It allows adjustment of focal length, color filters, skin-smoothing intensity, and facial brightness.
Among Chinese smartphone brands, Vivo continues to lead in portrait imaging, reproducing skin tones and textures naturally and sharply without excessive smoothing.
