Great work! How do you match the focal length of the lens used in the old photo?

Thanks! I don't measure the focal length precisely - I mainly try to stand in the same spot and then zoom until the perspective matches by eye.

That strategy works, seeing the results!

One more question: have you gained any insight into the focal lengths of the lenses regularly used for the antique photographs you rephotograph? Are they indeed around a standard lens (about 50 mm full-frame equivalent), or also wider? I collect old cameras to rephotograph images, and since zoom lenses were not yet in common use in the period of my interest (1912 - 1940), I acquire lenses with focal lengths between 25 and 55 mm to have sufficient range of choice. Maybe your camera indicates the focal length of the zoom position and you noted it’s often 50 or any other mm (full-frame equivalent)?

That's a good question! Honestly I don't really track focal lenghts, I usually match by eye. For panoramic views from far, like this one, I usually don't have any problems, it's only tricky sometimes with close buildings. It's cool that you're researching that! I should maybe get more into that as well. For this photo I used a Sony DSC-RX100M2 with the focal lenth at the wide end (10mm).

Thanks! The Sony DSC-RX100 II uses a 1-inch sensor with a crop factor of approximately 2.7× compared to full frame (35mm). For reference, the built-in lens covers 10.4–37.1 mm (28–100 mm equivalent), placing 10 mm at the wide-angle end.

Moret-sur-Loing is an ancient town on the banks of the Loing River near the mouth of the Seine, in the Seine-et-Marne department. Due to its location, it played an important commercial and military role in the Middle Ages. Many of its town fortifications, built primarily under Philip Augustus around 1200, are still preserved today, including the two city gates, the Porte de Bourgogne (seen here on the right in the picture) and the Porte de Samois. The Église Notre-Dame de Moret also dates from the same period.
Originally, there were numerous mills along the bridge. These disappeared in the course of industrialization and due to destruction during World War II, when the retreating German army blew up the bridge. The mill visible in the picture is a later reconstruction in the historical style.
