You already have two very good lenses, which will cover most (if not all) photographic needs.
For a newcomer to DSLR photography, your equipment is top notch!
Maybe in the future you will feel the need for an extreme wide, or a tele-zoom.
Some people extensively use their extreme wide angles, while others use them very, very rarely.
Maybe you'll never need an UWA, but with time you'll likely find that sometimes you need a lens to photograph distant subjects.
If/when it happens, please also consider cheap vintage lenses.
Even if you want AF, which of course is very welcome with longer focals, there are options that allow to save plenty of money, and are still competitive with modern solutions at medium diaphragms.
An example is the Pentax-F 70-210mm. If you search the forum for pictures taken with this lens, even if you consider only full frame shots, you'll see what i mean
It's not the easiest lens to find, but the cost is almost negligible, compared to any modern objective in the same focal range, 3rd party or Pentax.
As i already mentioned vintage AF lenses... i have a question for experienced K-1 owners who happen to be reading this thread:
I own a good number of F and FA zooms, and i am using mostly primes, so i'm rather hesitant to invest in a new D FA zoom for my K-1.
Let's take one lens as an example, apart from AF noise/speed, is the old Pentax-FA f4-5.6/28-105mm so inferior to the new D FA version?
Considering the very good high-ISO performance of the FF sensor, it's not difficult to shoot most pics at f8/f11. Stopped down, can you really see the difference?
I'm asking because a 28-105mm isn't the easiest zoom to design...
Longer focals should be more forgiving. I still have too few shots, though my first impression is that the Tamron 2.8/70-200mm should not trump the Pentax-F 70-210mm stopped down.
