Common questions
Why would a scene-of-crime unit prefer mirrorless cameras for new purchases?+
Mirrorless bodies are generally lighter, offer real-time exposure preview through the electronic viewfinder which helps avoid retakes in difficult lighting, and typically support faster and quieter shutter operation, all of which suit rapid, high-volume scene documentation better than an optical-viewfinder DSLR workflow.
Does the camera type itself affect the evidential value of crime scene photographs?+
Not directly. What matters for evidential integrity is consistent exposure, an unaltered original image file, correct metadata, and a documented chain of custody, all of which can be achieved with either a DSLR or a mirrorless camera provided the department's imaging protocol is followed.
