External Accessory Lenses
Wide angle conversion lenses increase angle of coverage so you can get
closer to your subject while still fitting everything in the frame.
Use adapter 9306.81 to attach 67mm threaded wide angle or macro
accessory lenses.
Use adapter 9306.79 to attach bayonet mount style accessory lenses.
Slight vignetting will likely occur at widest angle camera lens setting with
these lenses. Zoom in to eliminate, or crop the image in post processing.
6430 W-30 Wide-Angle Conversion Lens
The front of the lens port accepts the Ikelite 6430 W-30 Wide-Angle
Conversion lens and other 46mm threaded wide angle or macro lenses.
NOTE: The W-30 lens comes with both 46mm and 67mm threads
attached. The A2500 will not vignette at the camera’s widest angle
setting underwater when using the W-30 lens. Other 46mm lenses may
vignetting at the widest angle camera setting.
