Human: What is the difference between a digital SLR camera and a conventional camera? Assistant: 
The main difference between a digital SLR camera and a conventional camera is that a digital SLR camera has a much larger sensor which allows for higher resolution and better low-light performance. A digital SLR also has interchangeable lenses so you can choose the lens that best suits the image you want to capture. Additionally, digital SLRs have more features such as faster shutter speeds, advanced metering and a stronger flash, which make them a better option for professional photographers.
