Detailed Summary

This video discusses the author's personal experiences and impressions of using the Oppo F9 Pro and Vivo X300 Pro, along with their respective teleconverter lens kits, for capturing photos and videos at concerts. The author emphasizes that this is not a direct comparison test due to the inherent difficulties of shooting alone in a dynamic concert environment. Instead, the focus is on subjective experiences and practical usability for fans who want to document their favorite artists for personal use and social media sharing.

Challenges of Concert Shooting

The author highlights several key challenges specific to concert environments:

Single Operator Limitation: Being alone means shooting one phone at a time, making direct side-by-side comparisons impossible.
Dynamic Lighting: Concert lighting changes rapidly, often within half a second, making consistent exposure and color challenging.
Artist Movement: Performers move constantly, requiring quick focus and framing.
Atmospheric Effects: Stage fog and haze can create a soft, diffused look, which is not a camera defect but an intentional effect.
Equipment Restrictions: Bringing external grips or tripods is generally not allowed at concerts, necessitating handheld shooting.

Photo Quality and Performance

General Shooting (Without Teleconverter):

Both Oppo F9 Pro and Vivo X300 Pro perform very well in typical concert settings.
Color Accuracy: The Vivo X300 Pro is noted for rendering white colors more accurately to real life, while the Oppo F9 Pro tends to have a slight yellow cast.
Exposure Tendencies: The Oppo F9 Pro tends to brighten the entire frame more, whereas the Vivo X300 Pro focuses light on the artist, with the surroundings becoming slightly darker. This is presented as a matter of personal preference.
Versatility: Both phones excel across various focal lengths, from ultra-wide to their native telephoto capabilities (3x optical zoom on Oppo, 3.5x on Vivo), before attaching teleconverters.

Teleconverter Lens Usage:

The teleconverter lenses are described as passive optical elements that magnify the image captured by the phone's native telephoto lens. They do not have internal components or apertures.
Purpose: They allow users to bring distant subjects closer, enabling detailed shots of artists from far away.
Dedicated Modes: Both phones have specific modes for using teleconverters, which are necessary to correct image orientation (flipping) and apply specialized algorithms.
Performance: Both phones deliver impressive results with the teleconverters, bringing distant artists into clear view. Colors are well-reproduced and close to what the naked eye sees.
Subtle Differences: The main difference observed is a slight variation in color tone, with one being slightly darker and the other slightly lighter. These differences are only noticeable when images are placed side-by-side.
AI Enhancement: At high zoom levels, AI plays a significant role in reconstructing lost details. The Vivo X300 Pro's AI processing on faces can sometimes appear slightly artificial upon close inspection, though it's generally acceptable for social media.
Skin Detail: The Oppo F9 Pro is noted for retaining better skin detail when shooting with the teleconverter at closer ranges (e.g., from the front row).

Concert Mode:

Both phones feature a dedicated "Concert Mode."
Post-Processing: After taking a photo in concert mode, the image undergoes several seconds of AI processing. This results in the artist appearing more prominent against the background, with darker backgrounds becoming blacker and colored backgrounds being enhanced.
Final Render: The author advises waiting for the final render after shooting, as it is significantly better than the preview seen through the viewfinder.

Video Quality and Performance

Overall Quality: Video quality between the two phones is very similar, with or without the teleconverter lens.
Oppo F9 Pro: Tends to brighten the entire frame.
Vivo X300 Pro: Offers higher contrast and more saturated colors, making videos appear more impactful.
Color Accuracy (Red Tones): The Oppo F9 Pro is better at accurately reproducing red tones, whereas the Vivo X300 Pro sometimes renders reds as slightly orangey.
Sharpness and Detail: Both phones offer comparable sharpness and detail.
Exposure Adjustment During Zoom: Both phones initially experience a brief increase in brightness (about 1 second) when zooming with the teleconverter. However, they automatically adjust exposure settings (shutter speed, ISO) to achieve a balanced scene within about half a second to a second, which is considered acceptable for concert conditions.
Oppo's Video Improvement: The author notes a significant improvement in Oppo's video recording capabilities compared to previous models, particularly at higher zoom levels, with better brightness control and less "mushy" or "flat" image quality.

Audio Recording

Oppo F9 Pro: Is considered superior in audio recording, capturing more bass and creating a more immersive soundscape.
Vivo X300 Pro: Audio quality is acceptable but less impressive than the Oppo.
Audio File Access: The author provides links to download raw audio files for listeners to compare.
Concert Audio Limitations: The author reiterates that audio quality is heavily dependent on seating location and the venue's acoustics, with distant seating offering a compromised experience.

Hardware and Accessories

Oppo F9 Pro Photography Kit:

Includes a case, a padding/spacer, and a teleconverter lens.
Grip: Lacks an integrated grip, requiring the user to hold the phone and lens assembly directly.

Vivo X300 Pro Photography Kit:

Includes a case, a padding/spacer, a teleconverter lens, and a detachable grip/handle.
Grip Advantage: The integrated grip significantly improves handling comfort, especially with the added weight of the teleconverter. It connects via USB-C and provides a much better feel for extended shooting sessions (3-4 hours).
Physical Controls: The Vivo's grip features a physical dial for EV adjustment, which is faster than on-screen adjustments on the Oppo.

Oppo F9 Pro (Alternative Grip):

An official grip accessory is not sold in Vietnam but can be purchased through unofficial channels.
Magnetic Attachment: This grip uses a magnetic system (similar to MagSafe) and connects to a case.
Bluetooth Connectivity: It connects to the phone via Bluetooth, requiring the grip to be powered on.
Functionality: Offers a comfortable grip, a shutter button with half-press focus, a double-press to launch the camera, and an EV adjustment wheel.
Versatility: Can be rotated for vertical shooting, a feature not available on the Vivo's grip.
Comparison: While comfortable, it's slightly less so than the Vivo's integrated grip due to its smaller size.

Teleconverter Attachment/Detachment:

Oppo F9 Pro: The teleconverter is attached and detached via a simple sliding mechanism, making it quick and easy. This is advantageous for switching between wide-angle and telephoto shots.
Vivo X300 Pro: The teleconverter is attached via a screw-on mount. While the lens itself can be removed separately, reattaching it in a dark concert environment can be cumbersome. The author prefers Oppo's simpler attachment method.

Vivo Grip as a Power Bank:

The Vivo's grip also functions as a supplementary battery, allowing users to charge their phone while shooting.
