| Originally posted by chuck_c Does anyone have a recommendation for a good lens spanner ? I have found a number of them out there and quite a wide price range. I was just wondering if one of you here, actually working on lenses, can tell me of one that you have been using that is dependable and of reasonable quality ? I have the cheaper one that I got from Micro Tools (Europe) and it works relatively well. I also use a caliper at times. J | |

| Originally posted by Tickolas Just thought I'd share my experiences taking apart a preset version of the Takumar 50mm f4 macro Originally posted by millesr I have an M 1:3.5 150mm. Does anyone know how to remove the front element. - Some models require removing the tailpiece/mount in order to access the fasteners that allow deeper access. - Some models require racking the focus to minimum or maximum to expose hidden screws. - There are a couple of models that have screws hidden under the focus ring rubber grip. These models require removing the rubber grip, and then rotating the ring to make the access hole line up with the screws underneath. | |

Not relevant to this thread, but I have a beat up Auto Chinon 28/2.8 M42 that had a rubber grip, now gone, and a hole under it that lines up to a screw head. Did not realise it is probably part of the original design. | |

They are easily the best out there, and an absolute steal at $38. These are real, high-quality tools, rather than the chintzy crap that is sold at Micro-Tools. Their excellent stiffness allows for much greater purchase on spanner slots/holes than do any of the flimsy models commonly seen out there. The only downside to being well-built is that they are rather chunky, so in some cases, you might need something smaller/narrower for particularly tiny rings. | |

| Originally posted by Tickolas Just thought I'd share my experiences taking apart a preset version of the Takumar 50mm f4 macro. In my case the aperture rings had started separating due to a broken screw allowing other screws to wiggle loose. I've written down a guide for this fix along with pictures here. Originally posted by dcshooter Just posted partial disasssembly instructions in this thread for the DA15 for those with problems with focusing issues. ---------- Post added 04-14-15 at 06:20 AM ---------- If you haven't bought one yet, buy your spanners from SK Grimes.
