In the shot looking through binoculars, there are 2 overlapping circles. When actually looking through binoculars, the vision of both eyes should coincide, so there should be only one circle.
This is another of the prop department's mistakes in which Sergeant Schultz is wearing a uniform with his Luftwaffe eagle and swastika placed backwards on his chest. In the opening scene in Klink's office, the eagle should be facing left towards the heart, but is facing away to the right. His backwards swastika is not properly displayed by showing its vertical lines on the upper left and lower right sides, but has his vertical lines on the upper right and lower left sides.
After Martin writes Klink the note, their conversation seems to be in a manner where they think that they are being listened to. Klink should be checking his office for bugs shortly after this.
UPDATE: This is not a goof. After Martin/Seifert leaves Klink's office, Klink calls Hochstetter to report on their conversation. Klink reads from Martin/Seifert's note including his explanation: "Writing so prisoners in outer office cannot hear." Two POWs were shown cleaning the outer office when Klink and Martin/Seifert entered Klink's office.

In one sequence, the tall brown hills of California are seen just outside the "camp".
The scene of the trucks blowing up are models in a diorama, the explosions seen are firecrackers.
Monte Markham plays Captain James Martin/Seifert. The end credits show him playing a Lieutenant James Martin.
There are reflections in Klink' monocle from the production lights.
Hogan, after reading the recent transfers, notes that Klink transferred out a sergeant who was in the 395th Bomb Group. Hogan says, "Klink had him transferred out so he wouldn't blow the whistle."
Klink would have transferred him out BEFORE Martin showed up at camp. Yet he didn't know that Martin was a spy placed by the Gestapo till AFTER Martin revealed himself to Klink.
Klink had no reason to transfer the sergeant. He had no idea which BG Martin would supposedly be from nor that Martin was even a Gestapo plant/spy.

After Martin pushes Schultz, Klink arrests Martin and has him taken to his office. As the ranking prisoner at Stalag 13, Hogan should have gone to Klink's office to protect and/or defend Martin.
When Hogan and the gang are planning the munitions train job, Carter suggests using contact fuses to detonate the explosives - which would happen when the train passed over the contact fuses. However, when he and Newkirk are planting the explosives, they have a plunger-type detonator box with them, which they leave behind, as they are not carrying it when they go back to Hogan and LeBeau so they can plant Martin's jacket.
