A range of test shots are shown over the next three pages. Here, the full size image has been reduced for bandwidth purposes, and a crop taken from the original full resolution image has been placed below it in order for you to gain an appreciation of the overall quality. The following page consists of resized images so that you can evaluate the overall exposure. For those with a dial-up connection, please be patient while the pages downloads.
This wide-angle shot looks fine at first glance, with good exposure and colour balance, but there is a lack of resolution that betrays its interpolated origins.
At 64 ISO, this is about as good as it gets with the Z1. There is a reasonable level of detail and colour rendition is acceptable, but there is a general softness to the image and purple fringes around the highlights.
At ISO 100, there’s not much difference generally from the previous shot, but there are a few noise reduction artifacts in the darker areas.
At 200 ISO there is a distinct speckliness creeping into all areas of the image, but most noticeably in areas of plain colour.
At 400 ISO there is a sudden drop-off in image quality, with an overall loss of detail and blurring of edges. Colours remain reasonably accurate however.
To be fair, 800 ISO would never be used on such a bright day, which probably explains why the sky looks so awful, but the rest of the image is usable despite a general loss of detail.
