Re: Pentax smc DA* 50-135mm SDM Issue

I thin your seeing 2+2 and making 5

your theorem is based on SDM lasting the 12 months warranty period .!

Yet in 90% of the world Pentax lens come with 2 years warranty and on top of that through most of Europe will have a consumer protection for design failure in the 6 year region.

So why would Pentax keep quite on a ticking bomb when in most of the world it is themselves who will foot the bill and get hit with bad publicity to boot.?

On your 'new motors' again I see no evidence accept from the same discredited third party source in Germany.

I would consider it a lot more likely that failures are not that great and though earlier ones are more likely to fail (probably due to manufacturing tolerances) Pentax decided that FoF (Fix on Fail) was cost effective for all units sold.

My 50-135 was replaced by Pentax UK after 4 year free of charge and the motor is identical to the original, the revision status of  the Motherboard was newer but I can't remember now what its markings were.

So we have

2008 purchased 50-135

2010 first reports about new motors

2012 2nd rumour about new motors reported

late 2012 50-135 replaced directly by Pentax UK (not repairers) motor is identical unit as 2008 original.

The 50-135 I received was not a new unit but a factory refurb being the unit all UK reviews are based on (i.e demo stock) so would have all mec releases fitted.
