Context: I have a bunch of DA Limited and DA* lenses, using it with a KP I bought used 3 years ago. The KP is excellent, but (but but but) when new shiny thing arrives, one can't help but start staring at it. Let's just say I want even better dynamic range and iso performance, better autofocus too, while more resolution does not harm. That's why I have been saving and preparing a bit of fund to invest in a new camera next year. Obvious candidate is the K3iii, but since the price would be >2000 euros, a K1/K1ii is increasingly attractive even if I am never really serious with moving to FF. After all I love trying new things.
I like landscape photography, and occasional portrait.
The cons of going for the K1 rather than K3iii, to me:
- Weight and size. Portability.
- Cost of future lenses. I have a few good FF or FF-ready primes so I have time
What about the pros? I like the KP+16-50 a lot, so I could imagine to go for the K1/24-70 combo if I go that route, because the price is quite good, but does that really make a difference?
I am in a similar position to yourself, being very tempted by the new K3iii (it is new, shiny and exciting) but nervous about the price, especially as I would want a battery grip, of which there is no news (hopefully it will be the same as the K3 one but I doubt it). The cost of the new model is very off putting and its handling and performance would have to be spectacular for me to consider the upgrade. Where I would be able to see the new model in the flesh and have feel is beyond me at present. At the touted introductory price point the K1 new or used is now very compelling. I have both the K3 and KP and would part with the K3 if I upgraded.
Because of the size of my hands and the shape of the hand grip I require a BG for handling on the K3 series so I find the difference in size and weight between a K1 without BG and K3 with to be negligible.File sizes on the K1 can be bigger, but these can be reduced if needed. Indeed you may find shooting in square format with a DA lens a good option with the K1.
If you were to sell your KP, you may get Eu500-600, maybe a bit more if you sold the 16-50mm too, so you would be looking to finance around Eu1500. In your position, I would treat myself to a used K1 together with the 28 to 105mm or nice legacy prime or two, like the K 28mm f3.5 and K 55mm f1.8. Preferably though I would keep the KP if I could afford to and still go for the K1 option. This would give you more flexibility - KP for snaps, speed, light weight and convenience and K1 for more considered work. Alternatively for Eu1500 you could get a second KP body,plus BG, plus a high end lens which is not currently in your line up. Again increasing your flexibility. If you had to sell your KP to finance a K3iii you may end up regretting the lack of tilting screen and built in flash and the latter in the case of the K1.
Being as you already have some good FF primes, a used K1 and keep the KP seems the most sensible solution as it will add more variety to your shooting options.
