”A range of test shots are shown over the next two pages. Here, the full size image has been reduced for bandwidth purposes, and in some case 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.”
Here’s usual detail test shot. See below for a full res crop, or click to see the whole picture.
The level of detail produced by the lens 1/1.8-in sensor is exceptionally high, among the best of 10MP compacts.
The lens does produce noticeable barrel distortion at the wide-angle end of the zoom range, but overall sharpness and detail are excellent.
This corner crop from the above image shows the high level of edge and corner sharpness. It only falls off in the extreme corner of the frame.
Unlike a lot of 10MP sensors the A30 copes well with high contrast.
There is almost no fringing around this high contrast edge.
The wide-angle end of the zoom range is equivalent to 38mm.
Taken from the same spot at the telephoto end, equivalent to 114mm
