Robert Capa uses a Leica camera with a Summar 5cm lens. This type of lens needs to be extended out from the camera to enable it to focus an image onto the camera's film. However, in the movie, the Leica's lens is shown in its collapsed, unusable position, even when Capa is taking pictures with it.

In one of the Spain scenes, Gellhorn shows up in a T-34/85. The scene takes place in 1936. No T-34s of any type appeared in Spain. The T-34 in general did not appear until 1940. The T-34/85 came into service in 1943. The tank in the movie was probably meant to represent a T-26, which are harder for filmmakers to find.

During the scene at the hotel, after the bomb (51'23"), Hemingway is shown using a photographer's vest with a plastic zipper. These weren't made until the 60's.
