That's all well and good in theory. So let's try this scenario:
You are a on a 4-5 mile hike with the lens in zoom lock for easier transport because you have a lot ground to cover and wildlife isn't exactly on a schedule.
Suddenly a target appears in the tree 50 feet away from you, you unlock, zoom, focus as fast as you can because birds don't exactly sit still...
You get that picture just as a deer pops it's head out of the undergrowth 10 feet from you. Rack the zoom back to 150 and get that shot too.
True scenario, happened this last weekend on the White Oak trail in Newport News/Yorktown area. Maybe that's what did it, but isn't that why you have a zoom in the first place?
Sounds like the 150-450 is ill suited for this scenario? It's certainly not user negligence as it seems has been inferred.

I'm apt to agree with this conclusion.
Since when is the burden on the photographer to accommodate a lens quirk that runs counter to the very purpose and use of the lens?

And so where does one draw THAT line? Am I pro because I make a decent amount every year selling my work for the past 6 years? Or am I an amateur because it's not enough to allow me to quit my day job? I take very good care of my equipment to the best of my abilities, but I'm using my gear in the field and sometime s(&(&t happens. If I'm an amateur does it mean I'm at fault for this issue? If I'm a pro, does it mean Pentax has a design issue?
P.S.
So for what it's worth, B&H is going to take the lens back and repair it for me, which I think is just awesome, especially since Pentax told me sorry, you're on your own because you bought it "used".
So kudos to B&H for taking care of the situation.
Stand by for an update in 4-6 weeks...lol
