Replaceable lens module having a spring plate

An image capture device, comprising:

• a lens barrel disposed in a body of the image capture device and that includes one or more internal lenses disposed in the lens barrel;
• a bayonet coupled to the lens barrel;
• a replaceable lens module configured to removably couple to the bayonet and that includes:
• a retaining ring;
• an external lens positioned in an opening of the retaining ring;
• and
• a spring plate coupled to, or integrally formed with, the retaining ring, the spring plate configured to engage the bayonet and elastically deform to create a friction fit between the bayonet and the spring plate;
• and
• a seal positioned between the retaining ring of the replaceable lens module and the body of the image capture device.

A replaceable lens module for an image capture device, the replaceable lens module comprising:

• a retaining ring configured to removably couple the replaceable lens module to a bayonet of the image capture device, wherein the bayonet includes one or more fingers that project radially with respect to an optical axis of a lens barrel;
• an opening disposed in the retaining ring;
• a replaceable lens disposed in the opening, wherein the replaceable lens is configured to be aligned to the optical axis of the lens barrel of the image capture device using the retaining ring;
• a spring plate that extends from the retaining ring and is configured to engage the one or more fingers of the bayonet;
• and
• a seal compressible between the retaining ring and a body of the image capture device,
• wherein the spring plate is configured to elastically deform when engaged to the one or more fingers of the bayonet to exert a biasing force on the retaining ring and the seal to retain the replaceable lens between the retaining ring and the lens barrel.
