|Upon arrival of a Canon S95 test sample, it is tested in our DIWA Lab. The technical data of the rigorous tests are processed and translated into understandable data. Inside the lab, testing takes place in standardized circumstances. An environment in which cameras, both compact and system concepts can be compared without a problem. Besides that, the Canon PowerShot S95 camera is extensively used in practice and evaluated as for operation and shooting in practice. This combination of lab tests and the testing in practice, results in a final conclusion that is carefully reviewed.|
|Canon PowerShot S95 color reproduction
The Canon PowerShot S95 camera’s color reproduction is lively, without too much saturation. The green, red and blue channels are a bit more saturated, but this ensures for a natural-looking total picture. DIWA lab tests show that the Canon S95 has a constant color reproduction across the entire ISO range, and that it is fairly accurate according to the Gretag Macbeth Colorchecker. Skin tones are great; they also have a natural-looking color reproduction. The automatic white balance corrects a lot automatically and delivers a balanced lighting. The manually measured white balance is very accurate and constant throughout the whole ISO range.
Canon S95 signal/noise ratio
The signal/noise ratio, measured in the DIWA lab, shows a slight improvement in comparison with the S90. The Canon PowerShot S95 performs well to excellent up to 800 ISO, but from 400 ISO we see a loss of detail due to strong noise reduction. The Canon S95 has managed to improve in the higher ISO values, so that more detail is preserved. At 1600 ISO and higher there is a lot of loss of detail due to strong noise reduction, and chromatic noise also increases. This is inherent in the use of a small sensor. It is not a surprise that the results are fairly similar to those of the S90, as it most likely uses the same sensor and DIGIC 4 processor.
Canon PowerShot S95 dynamic range
The standard settings for dynamic range give a pretty much equal result, compared to its predecessor. Only at 800 ISO do we see a small decrease in dynamic range, but the Canon PowerShot S95 performs very well across the entire ISO range. The new Dynamic Range (DR) function gives a little extra room.
|A disadvantage is that enlarging the dynamic range automatically means increase the ISO value, so that the chance of noise increases as well. Although, in general the results of applying this DR function are of good quality and the function is an added value for the camera.
Canon PowerShot S95 lens
The lens sharpness has seen an improvement, especially the edge blur of the middle focal point and the tele range. With the S90, there was a slight edge blur visible at both focal points, but the Canon PowerShot S95 has managed to improve this point. From aperture f/4 there is practically no more edge blur to speak of. Center sharpness is excellent across the entire zoom range.
Canon S95 distortion of the lens
Distortion is normal in a zoom lens. This is different for the Canon S95 camera, as distortion is only slightly present. The amount of distortion in the tele-range is especially remarkable, rather almost the lack thereof. We compared JPEG and RAW shots and the test results are equal. We can assume that Canon is not making any corrections inside the camera to suppress any kind of distortion with software.
Canon PowerShot S95 chromatic aberration
Rather, Canon could have done better by applying corrections as far as chromatic aberration is concerned. Especially in the wide-angle range, chromatic aberration is visible and only increases across the aperture range. In terms of vignetting, the Canon PowerShot S95 has everything in order. There are good to excellent results across the entire range, so that vignetting is not a problem.
