This shot shows the vignetting caused by the proximity of the lens to the CCD. It’s easily visible, especially on the left. Also, those spots at the top of the frame are dust particles on the sensor.
Again, the difficulty with accurate framing has produced a less-than-perfect shot. It is also slightly under-exposed, and there is a lot of dust on the sensor.
Another rainy-day shot, but this time the exposure meter has got it right and the colour saturation is excellent, although this was the best out of five attempts.
