Not on your list but still available there is a
Tamron 70-200/2.8 without image stabilisation. It is a screw drive lens but enjoys a rather favourable reputation amongst Pentaxians.
@Mistral75: Do you think there is any chance that the price of the Pentax 70-200 will come down after a while?
How do you convince someone who is not invested in a system yet to choose Pentax when key lenses are more expensive than the top price lenses from Canikon despite the fact that they do not need to implement image stabilisation?
AFAIC, camera ergonomics and pricing have been a strong argument in favour of Pentax, but there are of course other trade-offs like ubiquity of dealers / fellow users, so how do I explain to someone that it is worth paying more for Pentax lenses?
A salesman could argue that most people will change their camera more often than their lenses and hence the Pentax price balance is the better one long-term, but I'm not sure how many customers would be susceptible to this kind of argument.
