I have a Sony 3.5-5.6/18-55 SAM (part no. SAL1855) lens that has taken a knock and the zoom ring is now stuck fast at 55mm and the focus ring doesn't want to pull all the way in.

Are there any guides or manuals that would help me take it apart and hopefully get it repaired? It was bought used (with the camera) and well out of warranty and as its not a mega expensive lens to replace I'd like to have a dabble - its as much use as a paperweight at the moment so I can't wreck it any more than it already is!

There is a SAL1855 service manual here

Actual link is via "Get Manual" at lower left of page - appears authentic. 40 pages in English and 78 total. Attempting to just copy download address directly failed - they control free downloads to 2 per day and that is probably part of their mechanism for doing so. It would be interesting to see what else they have.

NB - Note their comment - "This lens can disassemble both the 1st lens side and the mount side". I take that to mean that you can legitimately gain access from either end. You may wish to consider what is probably wrong with your lens and whether partial disassembly from one end or the other may work best. The magnificent exploded assembly diagram should help with these prognostications.

Disassembly section starting on page 2-1 looks extremely helpful. You will (probably) have to improvise their "special tool" universal wrench - a pair of drawing compasses with two sharp points or a wide opening circlip pliers may suffice.

Cheap it may be. Totally simple it isn't.

  • Exactly what I'm looking for thank you. I know these things have a bazillion parts inside so didn't want to just attack it with a screwdriver! :) – Eeji Aug 4 '14 at 17:42
