Service Manual: [[staff:servicedb:Leica-R35mmf1.4|Disassembly/Re-assembly]] \\
\\
Full CLA: **4-6 hrs.**\\
<wrap note>This particular lens can be very finicky to get the focus feeling good due to the floating group system, so quote on the higher end.</wrap>\\
re-collimate: **1 hr**\\
<wrap note>remove focus gear (if any), rubber focus grip and loosen screws and shift focus ring to achieve collimation (assuming the pinch ring hasn't been glued down). Make sure screws have good hold on pinch ring underneath. If not, will need to disassemble front section to access focus mechanism. </wrap>\\
Polish and re-coat Front Element: **1 hr. + P+C cost**\\
<wrap note>1 hour in house labor for removal and installation. Front element does remove from housing. </wrap>\\
clean Iris Blades: **4-5 hrs + 1 hr**\\	
speedbooster mod (not offered):\\
<wrap note>we do not offer rear mod for speedbooster clearance especially for mirror in Canon 5D</wrap>\\
Centering adjustment: **2-3 hrs.**\\
<wrap note> 1. Take the floating group out.  From the rear, remove the first two elements you see (indicating their orientation as you go).The first is the visible concave element, and the second is the plano-convex element below it. The revealed element below those is the one you need to spin.  </wrap>\\
