in need of advice for a tele lens for the Kr

I bought the Pentax Kr with the kit lens - 18-55 and 55-300.
I will soon be going on a safari and am worried that the zoom of the 55-300 lens isn't strong enough to get some of the animals real close, so I was thinking of maybe buying an older lens, like the smc A*300/4, since (I think???) the light quality is better and maybe the image quality might be better than with the kit lens, anyone have good advice for a novice like me?
Thank you in advance

If you're going to get another lens, you may as well opt for a focal length beyond 300mm.

The sigma 50-500mm comes to mind as an option: Sigma 50-500mm F4.5-6.3 APO OS HSM Lens Review

How are you with manual focusing, particularly with the small viewfinder of the K-r?

I like to focus manual, it works out about 70% ok, still learning :-). Thank you for the help!

Well, then, you're doing a lot better than me!

Here are my thoughts on the matter, having never used the A 300 but having extensive experience with the 55-300: the A 300 will mostly likely be sharper when focused well. It's also faster. However, IMHO, it's not enough of an advantage to warrant spending another $500 (average price USD according to the review section) given that the 55-300 is already a good lens. Using the A 300 will necessitate changing lenses whenever 300mm is too long. Will the environment be dusty, dirty or wet? How leisurely is the safari?

A*300 with K-r

Just want to share with you my experience on using A*300/4 with Kr. Even with Katzeye OptiBrite installed, I can only get <60% good manual focus at f/4. I think any MF lens that is slower than f/2.8 would be hard to manually focus with Kr, because my success rate is pretty low with M200/4 & M150/3.5 lens as well. Whereas the M100/2.8 & ZK100/2 are way more easier to snap in focus with the Katzeye, not so without it. My best & easiest telephoto on Kr so far is the DA*200/2.8.

Yes I'm sure there will be dust and that is a very good thought better to stick with a zoom lens I guess.
