Originally posted by dlhawes I agree with @Des; unless the thread is limited by its terms (stated in the title or the original post), there is no limitation, as I understand it. For example, if the title of the thread specifies the use of a particular Pentax lens, then no Sony allowed. But if it says something like this thread's title, pictures taken with any long lens >= 300mm will be welcome. E.g., see @Pentaxians' post a few ahead of yours.

I think if you go back through the thread, you will find discussions about this appearing every so often.
As far as I know, the thread is about discussions with 300+ teles and their use, issues technique etc, using the resulting photos as support for a discussion, or simply to say, “look what I can do with this combo”
Someone once commented on one of my posts that I shouldn’t have posted because my Sigma 70-200/2.8 plus 2x TC didn’t qualify because although the combo was more than 300 mm, the base lens wasn’t. Go Figure?

Since getting the 560/5.6 and matching it up with my K1 I have switched for BIF shots to the 9point central sensor grid, because keeping a moving subject in the dead center of the frame is almost impossible and I would miss many shots if I used center sensor only for AF.
