ks> When I received my 24-90 I noticed that the long end was actually shorter than ks> my M 2/85. In the 'communication' I then had with Pentax Europe about this,
I think it was discussed a lot on B.Dimitrov's site that lenses with some form of internal focusing (not moving the whole lens in/out, but just part of the lens), often shorten the actual focal length when focused nearer than infinity. Not to mention some other issues IF might bring. So perhaps that's exagerrating the situation even more, the 90mm end is 5% off and when focused closer it's even more off...
