Confusion and doubts

Looking OP works, i would say that pentax/ricoh must jump over his pants to fulfill OP-s need to go ahead. There is nothing in current pentax lineup to go further.
No FF camera, no lenses. Is only big "IF" pentax will do: 1,2,3 ... and etc with good price.

From one point - yes FF in half of year or so, maybe is worth waiting and go another half of year will to get knowledge - what it really gives (and solve/sort out all errors developed with FF). But there is still no lens for it.
With no lens i mean - covered is mostly tele end- 70-200 and 150-450 line.
No FF UWA, no FF good standard lens. And do not start bully with DA this or DA* that. There is no lens in range 10-135 mm for full frame with real resolving power for landscape. No pentax lens go over 20-21 P-mpix, while canon seldom do above 30 p-mpix and nikon best glass go 40-44 P-mpix. smc DA 55 alone is not enough to cover FF. With most pentax crop lenses you can magnify till 30-50% from real size. Seldom 70-100% if shot as macro withs macro lens. No 100% printout with pentax lens on APS-c landscape. And Sigma does not help out here much too.

@ the moment best resolving power offers nikon glass on D810 followed closely by nikon D750. Decent metering, good AF and tracking (again no need for landscape). Looking pictures on OP-s web page i would say that single nikon 24-70 F2.8 - with stabilizer covers all OP-s needs. (yeah - there are new 50 megapixel canon -s, but they look more like freak-line, as they are lacking anything improved but resolving power over 5D mark III). Even 6D will be serious improvement over current K5 or K3 offer on landscape area.

one more thing on "IF"-s. looking pentax current lineup - no pentax camera has decent ISO handling. There is no such thing as real ISO performance above 1270, specially in poor light conditions, outdoors. You get nothing but ISO noise above 1250 in fog. As landscape shooter, this is serious drawback.
K5 does have some 1230 ISO limit , K3 1250-1270, 645Z sits in similar hole. Why would next FF perform much better in this area? I am very pessimistic in this area, as long i see on next FF that it really performs on ISO. I do not care how good it is indoors, taking selfies or birthday cakes.
What about K3, i would say it is very inconsistent camera. On some days it just excels, while some hours later it just can not make any decent picture, not having anything in focus on many pictures.
Some tell -nikon use same sony sensors as pentax. I see this more like problem, not as solution for my needs. And i proceed to think this way as long they prove opposite in practice.
Whatever they are lacking in engineering, problems persist in current lineup. I would say, that best cameras pentax has made are K20 and K5. There is no serious improvement after those ones. (have not used K-S2, but i bet it is as good or bad as K3 is).

So there is just 2 plain ways to go. You or stay and wait (as i do - because financial reasons) or you just do plain switch and can tell us how you improved after.

Shooting indoor sports with SMC FA 100mm f/2.8 Macro

In my opinion it will be really hard task because slowness of auto-focus if you try it but not impossible one. As i remember it was quite easy in manual mode, but not even close to DA55-300 -s speed used in manual handling.
Have used this lens for portrait (and for that task it performs extremely well) But 2 people you can get onto picture from 5-7m distance, closer one will be out of frame.
Even shooting general talking on birthday event was not too good. Yes i got pictures needed but i cant imagine this working right in fast moving situations.
Expecting you get some in focus from 70-80 % misses if it is fast sport.

i would consider this on 2 occasions:
1 i have absolutely no other choice and 2 - result is not too important.

Hmm, just idea. Go out and try it on some flying birds like seagulls if they are feeded somewhere nearby. If you easily can hit them with this lens, you can do same inside with people and have experience what to expect.

1st DSLR (pentax) and lens choice problem ;(

That means, while you learn you are zoom guy. Take look at your shots statistics, to predict areas you tend to shoot.
18-135 can do impressive things in right hands. it is not macro thou... for macro you need or real macro or smth else, but it makes good sharp closeups, resembling macro. It is best overall Pentax kit-lens by far and is WR, big bonus. To get sharper, you get limited by limiteds LBA :)

i have taken around a lot pictures with 18-55, even this one can take pictures, and must say better ones than your fujifilm.
if long range is not so important to you, you can take K-30 (i like personally less K-50 while inside it is 99,9% same as K-30) and 18-55 +some true macro for example. witch macro, it depends. if you are just in budget, K-30 with kit+some samyang 85mm,(or 35, 24) for sharp and fast shots, or some DA 21 for example.
Still, you must know your habits.



Sharp is good, but only on it's own place.
Most of true art is not sharp at all, or is sharp on some critical point

This is part, i would say ( and i am noob hobbyist) it's you, not your optics.
I looked your examples from x20.
You shoot often against strong light without filters. That means- ground is dark, or you blow up sky. You tend to choose sky.
You misplace often horizon by height. and x20 did quite not help you on DOF.
No camera nor lens does not help you truly out here. You have to learn limitations of your gear and take best out of ones you have.

in this means APS-c (any of them) may be sufficient and you may find it limiting -because they all have limits in plain pixel density on sensor.
You may get more growing room with K-3, but not too much, want to go higher, go FF.


This is really starter combo, most daily range covered. About kit i told, you could make nice pictures, with some trial and error, but you probably will want more details later. 55-300 is very good to handle, has very good telemacro at his price, but has also strong CA at long end. Because last it is usable in 55-225(250mm) range max.



Are you good enough for this lens? :)
With less joking, 18-135 and some limited or macro limited later will be good for some years.


All that said
K-30 (or50) is excellent piece, very good viewfinder. if it fits your hands and taste... i wouldn't consider anything else from pentax unless i can get FF (and FF means already different thinking habits and gear). K-3 maybe, but here price plays most role.
Last but not least -calculate decision is good, endless recalculation is no good at all. Even bad decision you stick with is better, than constant mind change.
