A range of test shots are shown over the next two pages. Here, the full size image has been reduced for bandwidth purposes, and a crop (taken from the original full resolution image at Adobe ImageReady jpg quality 60) follows each image in order for you to gain an appreciation of the overall quality. The next page consists of resized images (to Adobe ImageReady jpg quality 50) so that you can evaluate the overall exposure. For those with a dial-up connection, please be patient while the page downloads.
With a zoom range equivalent to 28-85mm, the GX8 has a wider wide-angle setting than most other cameras, great for capturing more of the scene. At ISO 400 noise has crept in.
A 3x zoom lens doesn’t let you zoom in far, but the 85mm equivalent telephoto end would be ideal for flattering portraits. Again the shot was taken at approx ISO 400 and noise is evident. For a cleaner image, use the GX8 at ISO64 and ISO100, ambient light permitting.
At the lowest sensitivity setting of 64 ISO there is no noticeable image noise and everything is fine. Likewise at 100 ISO the image is noise free, colours and exposure are accurate and the shot is quite usable. At the mid-range setting of 200 ISO an amount of image noise is beginning to creep into the shadow areas, but the image is still good. At the highest normal setting of 400 ISO image noise is clearly visible in the darker areas, but exposure is still accurate. At 800 ISO image noise is present right across the frame, and colour and exposure are clearly inaccurate. At the maximum setting of 1600 ISO the image is so noisy and the exposure and colour reproduction are so inaccurate as to make the image barely usable.
