+1.

What you might want to do is take and ND grad for sunsets.
Cheap Cokin P type mount off ebay, and something like a KOOD pro shouldn't break the bank but provide new functionalities.

Dust protection is really the only use I can see for another filter. The rocket blower should take care of most dust but definitely not all. Using a very soft brush is very useful, last resort is the cloth.
Good filters are expensive, and a filter of that size and good quality to enrich colors (e.g. CPL) would be expensive and not essential since that can be tuned in camera or in post.

Even for protection I am very reluctant to use a UV filter. But you might encounter severe dust while on safari, and rather than continuously cleaning the lens element, it might be better to clean a UV. I you do buy it, spend money on it because you don't want to degrade the image.

Thanks guys for the well (good?) wishes.

Now thats a camera bag that does not look like a camera bag.

Will do

I was in Camerabase today taking a last hopeful peek at their wares and selling some stuff (not a good idea price wise, but still...)
There were two other customers there and I could not refrain myself from paying attention once I heard "Pentax". Apparently this fellow with a K20D was checking out some M lenses, but they couldn't work out how to work with them.
"Exposure problems..." "aperture"
I approached the guy as he was leaving to inquiry about his predicament.
The issue was the aperture ring control activation. I soon sorted that out and the guy bought an excellent condition SMC-M 50mm F1.4.

Its nice to help people , but I cannot but wonder if he will end up buying more lenses to experiment now that he can use them. Could I have started a case of LBA?

All sold.

Sold!

All sold!

Remaining items no longer on offer. Going with the other heaps of stuff to the charity shop.
