Firstly, let's discuss the convenience factor. Mobile phones are incredibly convenient due to their compact size and lightweight nature. They are always at hand, which makes them excellent for spontaneous shots during events. Most modern smartphones come equipped with high-resolution sensors and intelligent software that can produce impressive images. They also offer features such as HDR (High Dynamic Range) and low-light optimization, which can be particularly useful in event settings where lighting conditions can change rapidly.
In contrast, mirrorless cameras, though generally more compact than DSLRs, are still bulkier and require carrying additional lenses and accessories. However, this added bulk comes with the benefit of superior image quality. Mirrorless cameras typically have larger sensors, which allow for better performance in low-light conditions, greater depth of field control, and improved dynamic range. This can be crucial in event photography where lighting is often less than ideal.
Battery life can be a critical factor during event shooting. Mobile phones often struggle with battery longevity, especially when used for photography, videography, and other tasks simultaneously. They generally require frequent recharging or the use of power banks. Mirrorless cameras, while also not immune to battery drainage, tend to last longer on a single charge, especially when not using the electronic viewfinder extensively. Carrying spare batteries is a simple solution for mirrorless cameras, making them more reliable for extended shooting sessions.
Mobile phones, in the right hands of someone that understand how to use the manual settings and understands the use of light can produce a half decent picture. However if looking professional results you will need a professional camera in the hands of an experienced photographer to be able to shoot in any environment no matter how dark or bright the light is.
