Anyone saying "it's just a prop" has no idea how advertising works, and how many hours of conference calls, Art Director meetings and Slack discussions will have gone into choosing even a stock photo for an image like this.
...the real significance of the picture (stock photo or not) is that using a film camera (especially a beat-up and well-travelled camera) is once more an aspirational image, appealing not just to film users, but to the regimented drones using a boring digital camera and romantically associating this idea of themselves as out-of-the-ordinary, slightly rebellious, creative and adventurous, traveling to far-flung parts of the world free of tourists snapping selfies with their iPhones, and using film to mindfully capture their exotic surroundings, without needing to check Facebook after each snap.
Whether real or not, the idea of film (just like vinyl) has evolved from being something only grandad still used, to once more embodying these values of adventurousness, creativity, youth, (yes even 'hipness'), and exclusivity.
