Yes. This post is pointless. It doesn't really serve any rational purpose, it most likely won't bring any particularly useful information to anyone.
I just had to ventilate! Switched to Pentax lately from Fuji mirrorless. I've been shooting my Takumars on that system for a while, using focus peaking in the viewfinder (EVF, naturally) and it works quite well. I did not like the crop very much and used a speed booster to get some of the framing back.
However, got the K-1 ii recently and the other day the Pentax 30120 M42->K adapter came in the mail. I got the 24-70 2.8, Samyang 85/1.4 and the DA 50/1.8 - but what I was truly looking forward to was to try out all the vintage glass on it. And holy c**p does the K-1 not disappoint!
1. Image quality. Coming from the X-T1, the bump in digital resolution from 16MP to 36MP is obviously noticeable. Taking the dynamic range and the color processing (Fujis are also great for color though) into the equation also, and my mind was blown!
2. Useability. I really liked focus peaking through the EVF on the Fuji - not a big fan of using the screen, so I haven't used liveview much on the K-1. However, that big and bright OVF makes focusing a breeze - and having the confirmation beep is a huge help in speeding up the process. I pretty much fast focus until the beep and then fine-adjust. I'm basically as fast as with focus peaking in-EVF - and yeah, those old lenses just look sexy on a DSLR body, without a huge adapter.
To conclude, I'm having a better experience shooting my Takumar lenses on the K-1ii than on mirrorless with focus peaking, which was a big surprise - it's just hard to argue against a big and bright optical viewfinder with confirmation beep!
