How frequently does the letter "b" appear in:
A special zoom sleeve for use with the Canon 10-18mm STM lens when used with the Canon EOS 100D Rebel SL1 in our Compact DSLR Housing. The full zoom range of the lens is accommodated by the housing's standard dome port without vignetting (dark shadows in the corners of the image).
This zoom sleeve is not necessary to use the Canon 10-18mm STM lens with any other model of Ikelite DSLR housings. Please refer to our Port Finder for information on using this lens with a Canon DSLR other than the EOS 100D Rebel SL1.
