Leica R7 issue

Hey, all. I've been having an issue with my R7 and my Summilux 50. I'm not entirely sure whether it's the lens or the camera, but 90% of the time, this pairing leads to super soft, weirdly exposed photos. For years, I had my (safari edition Summilux) paired with my R3 MOT and this resulted in fantastic images, but this camera was dropped and damaged by an ex-roommate. The top was dented badly and the metering electronics started popping out of the top plate, but it still metered well. Needless to say, back in the fall, I picked up an R7 from someone who was selling one here in Berlin along with a Macro Elmarit 60mm lens. With both the Elmarit 60 (though it was better) and my Summilux, the pictures were overblown, soft, and weirdly exposed. When I used the Elmarit with my Leicaflex SL, the pictures turned out quite well. I don't know what could have happened. Either it's my lens (which is quite difficult to focus, though I was able to get razor-sharp images in the past) or it's the R7. The Summilux has performed weirdly for a little while now, though. Perhaps an element came unstuck? It is extremely difficult to focus and seems to be off even when it's focused. As a test, I shot the R7 on program mode and was left with very odd images. I will attach them. What should I do? What is the more likely culprit, the lens or the camera?
