Sigma SD1 Merrill

The SD1 is a straightforward digital single-lens reflex camera that has a simple set of features but produces exceptional image quality at low ISOs ranging from 100 to 400. However, it disappoints with its slow file write times and inconsistent control behavior while performing this task. The high ISO image quality is not impressive, and it lacks live view for photography with a tripod. Although it is a specialized tool, if you can accept its drawbacks, it has the potential to deliver excellent outcomes.
