I have to hand it to the Sigma DP1 Merrill. It may be a pain in the backside to use (and a chore to post-process the images), but it really is capable of stunning image quality. It won’t be apparent from this jpeg but the resolution is astonishing; unlike anything I’ve used before. Even at 400% the detail is still present.
The 19mm lens does fringe somewhat, both magenta and green, but it can be dealt with.
This photo is a summer version of this one.
Addendum: Firstly, I have subsequently realised that describing a shot taken in March as a “summer” shot is not exactly accurate. Secondly, I’ve also noticed that the previous snowy shot was also shot in March… so we are not really talking about Summer and Winter at all but more about the vagaries of the English weather.
