I was wondering if anyone can confirm that there is no fixed glass element on the rear of this lens? I don't know how I would have missed noticing this on my first defective copy. It is just a fuzzy hole and I can see way into the guts of the lens and the rear element moves in and out when zooming.
I chatted with Pentax support and their response was that all DA* lenses are like that which is not true, I have all but the 55 and all have a fixed rear element that is flush with the mount.
My god, some-one stole the back glas of my 60-250 to! The 55 has a backglass.

Here is a picture of the back of the DA* zooms lined up together

The 60-250 is on the right. The back is open as you can see while the other two have a glass element that seals the lens body. Just trying to determine if this is normal or if mine is missing the glass. The fuzzy coating is like the inside of the lens hoods on the FA series. I lost my confidence in Pentax support when they told me they are all built like this?

Rest assured your 60-250 is not missing any glass; that's exactly how it's suppose to look.

I wonder if the 60-250 will accept the 1.4X-L TC on account of it's open back.

It looks like it would mount ok as there appears to be enough clearance at 60mm (where the rear element is the closest to the mount). That said, I don't have a 1.4X-L TC to confirm that
