Full CLA: **#hrs.**\\
<wrap note>Optics can be dropped out as an assembly much like a Cooke (with similar brass rollers), but the focus system is helical-based rather than cam follower-based. See above disassembly guide for details.\\
\\
In terms of serviceability/build quality, they are almost equal to TLS rehousings, and much better than GL Optics. </wrap>\\

C&A Optics: **#hrs.**\\
<wrap note>No centering options (outside of just spinning random elements) available.</wrap>\\
