For example, an image capture device may include a lens barrel in a body of the image capture device, the lens barrel including multiple inner lenses; a replaceable lens structure that is mountable on the body of the image capture device, the replaceable lens structure including an outer lens and a retaining ring configured to fasten the outer lens in a position covering a first end the lens barrel in a first arrangement and configured to disconnect the outer lens from the body of the image capture device in a second arrangement; and an image sensor mounted within the body at a second end of the lens barrel, the image sensor configured to capture images based on light incident on the image sensor through the outer lens and the multiple inner lenses when the retaining ring is in the first arrangement. ## Claims ### Claim 1 An image capture device comprising: a lens barrel in a body of the image capture device, the lens barrel including multiple inner lenses; a replaceable lens structure that is mountable on the body of the image capture device, the replaceable lens structure including an outer lens and a retaining ring configured to fasten the outer lens in a position covering a first end of the lens barrel in a first arrangement and configured to disconnect the outer lens from the body of the image capture device in a second arrangement, in which the retaining ring includes a bayonet mechanism configured to facilitate transition between the first arrangement and the second arrangement; and an image sensor mounted within the body at a second end of the lens barrel and configured to capture images based on light incident on the image sensor through the outer lens and the multiple inner lenses when the retaining ring is in the first arrangement. ### Claim 2 (depends on 1) The image capture device of claim 1, in which the outer lens is a curved lens. ### Claim 3 (depends on 1) The image capture device of claim 1, in which the outer lens is a fisheye lens. ### Claim 4 (depends on 1) The image capture device of claim 1, in which the retaining ring is glued to the outer lens. ### Claim 5 (depends on 1) The image capture device of claim 1, in which the outer lens is secured in the retaining ring as a captured mount, such that the outer lens may be rotated within the retaining ring. ### Claim 6 (depends on 1) The image capture device of claim 1, in which at least one of the multiple inner lenses is a curved lens. ### Claim 7 (depends on 1) The image capture device of claim 1, comprising: a waterproofing O-ring that is positioned radially around the outer lens. ### Claim 8 (depends on 1) The image capture device of claim 1, comprising: a waterproofing O-ring that is positioned inside the outer lens, between the outer lens and the lens barrel. ### Claim 9 A method comprising: disconnecting a first retaining ring from a body of an image capture device to remove a first outer lens from a position covering a first end of a lens barrel, the lens barrel including multiple inner lenses, in which the first retaining ring includes a first bayonet mechanism and disconnecting the first retaining ring from the body comprises twisting the first retaining ring from a locked position to an unlocked position and pulling the first retaining ring away from the body to remove the first outer lens from a position covering the first end of the lens barrel; and connecting a second retaining ring to the body of the image capture device to mount a second outer lens in a position covering the first end the lens barrel, in which an image sensor is mounted within the body at a second end of the lens barrel and configured to capture images based on light incident on the image sensor through the second outer lens and the multiple inner lenses. ### Claim 10 (depends on 9) The method of claim 9, in which at least one of the multiple inner lenses is a curved lens. ### Claim 11 An image capture device comprising: a lens barrel in a body of the image capture device, the lens barrel including a curved inner lens; a replaceable lens structure that is mountable on the body of the image capture device, the replaceable lens structure including an outer lens and a retaining ring configured to fasten the outer lens in a position covering a first end the lens barrel in a first arrangement and configured to disconnect the outer lens from the body of the image capture device in a second arrangement, in which the retaining ring includes a bayonet mechanism configured to facilitate transition between the first arrangement and the second arrangement; and an image sensor mounted within the body at a second end of the lens barrel and configured to capture images based on light incident on the image sensor through the outer lens and the curved inner lens when the retaining ring is in the first arrangement. ### Claim 12 (depends on 11) The image capture device of claim 11, in which the outer lens is a curved lens. ### Claim 13 (depends on 11) The image capture device of claim 11, in which the retaining ring is glued to the outer lens. ### Claim 14 (depends on 11) The image capture device of claim 11, in which the outer lens is a fisheye lens. ### Claim 15 (depends on 11) The image capture device of claim 11, in which the outer lens is secured in the retaining ring as a captured mount, such that the outer lens may be rotated within the retaining ring. ### Claim 16 (depends on 11) The image capture device of claim 11, comprising: a waterproofing O-ring that is positioned radially around the outer lens. ### Claim 17 (depends on 11) The image capture device of claim 11, comprising: a waterproofing O-ring that is positioned inside the outer lens, between the outer lens and the lens barrel. ### Claim 18 (depends on 9) The method of claim 9, in which in which the second retaining ring includes a second bayonet mechanism and connecting the second retaining ring to the body comprises: pushing the retaining ring onto the body and twisting the second retaining ring from an unlocked to a locked position to mount the second outer lens in a position covering the first end the lens barrel. ### Claim 19 (depends on 9) The method of claim 9, in which the first outer lens is secured in the first retaining ring as a captured mount, such that the first outer lens may be rotated within the first retaining ring. ### Claim 20 (depends on 9) The method of claim 9, in which the first outer lens is a fisheye lens.
