    Either that or the gears will be made stronger in all fittings and they'll all become more expensive!

    I've never heard of a Minolta or Sony lens having the problem ... so I put it firmly in Sigma's court.

    Oh, I would agree whole heartedly. No doubt they didn't put much research in when producing the lenses for the new Sony DSLRs.

    It would be most interesting to have a professional strip down and report on the quality of manufacture of various third party lenses. NOT just how well they perform optically but how well they are made in comparison with the manufacturer's own lenses. What gets lightened/omitted/cheapened etc. Or maybe even improved.

    Something AP could commission?

    Now that would be worthwhile and not only to Sony users.

    The problem with Sigma (not only with Minolta) is that they did not pay royalty payments for the technology, but, reverse engineered, therefore would not know exactly what the original tolerances Minolta designed into their lenses.
    So am not surprised that new Sony Alphas can strip Sigma lenses, I wouldn't be surprised if Sony knowing this issue didn't just up the power on the latest models knowing that legacy Minolta, Konica Minolta and Tamron lenses would be able to handle the torque, whereas Sigma lenses would not!

    I say, that would be a bit underhand would it not :eek:

    Why? I think that would be a completely reasonable business premise, if a competitor is circumventing your intellectual property/rights and your design/build specifications alter to the point that their reverse engineered product is no longer capable then I'd say that is their problem, the fact that it might also p*ss of some of their customers and maybe persuade them to get Sony/Tamron glass then I'd say result!
    If I were running Sony and Sigma weren't paying for license rights it's what I'd do :D
