HD PENTAX-DA 55-300mm F4.5-6.3

Thank you for viewing.
This is a dust and moisture-resistant zoom lens from Pentax.
I have taken good care of it, but I have recently had fewer opportunities to use it, so I am offering it for sale so that someone else can make good use of it. How about it for bird photography in the coming season? It's KAF4 standard, so the AF is fast and quiet.

The included accessories are as follows:
Lens, lens hood, lens filter, box, and instruction manual. That's all.
The warranty card is not included.
(All items are shown in photo 1.)

There is no history of dropping it.
I have attached a lens filter since I purchased it.
There are no noticeable scratches, but there is some fine dust inside.

I don't think it affected the photos, but please judge from the photos as it is from a layman's perspective.
If you have any questions or would like additional photos, please feel free to ask.

Notes:
I have tried to describe what I have noticed to the best of my ability. However, this is based on my personal standards. There may be oversights, so please feel free to inquire if you have any concerns. Please check the images and purchase if you can make your own judgment.
