Reasons to choose EOS-1D
Released in 2001, EOS-1D has about 548 mm² of sensor area, 4.1 MP effective resolution, and a 1,585 g body. Use these values to narrow the field, not as an overall image-quality score.


The EOS-1D and EOS-1D Mark II have the same sensor area. Compare pixel density, sensor architecture, and release generation to understand likely image-quality differences.
These cameras were released 3 years apart. Consider sensor generation when comparing pixel metrics.
Amber marks the value that is generally preferable in this comparison context. It is not an overall camera score.
The EOS-1D and EOS-1D Mark II have the same sensor area. The EOS-1D Mark II has the lighter body. The EOS-1D Mark II has the higher effective resolution. The EOS-1D Mark II is the newer release. Also consider the lens system and subjects you shoot.
Released in 2001, EOS-1D has about 548 mm² of sensor area, 4.1 MP effective resolution, and a 1,585 g body. Use these values to narrow the field, not as an overall image-quality score.
Released in 2004, EOS-1D Mark II has about 548 mm² of sensor area, 8.2 MP effective resolution, and a 1,565 g body. Use these values to narrow the field, not as an overall image-quality score.
