Technical Metrics from 1:100 to 1:2 Magnification
The 50/2M differs from the Milvus 100/2M in free working distance, depth of field and various other metrics.
Angle of view steadily narrows as the 50/2M is focused more closely, from about 45° at 1:100 to about 32° at 1:2 (vs 25° / 16° for the 100/2M). For copy work or flat art work, the 100/2M is a better choice for lower distortion and greater working distance and flatter perspective.
Not shown in the table: diagonal angle of view on full frame is twice the chief ray angle (object side, left figure in column), not acounting for any distortion.
