Panasonic S1 Review

Panasonic S1 Image Quality

All of the sample images in this review were taken using the 24.2 megapixel Fine JPEG setting, which gives an average image size of around 12Mb.

Images from the Panasonic S1 are impressively detailed – a cut above what we’re used to typically seeing from a mirrorless camera, which doesn’t lead us to believe this model is in any way the poor man’s choice in comparison to the S1R, even if that does offer practically double the pixel count here. Being a Panasonic camera colours are also vibrant and well saturated, even on the standard setting, with images displaying plenty of contrast. We didn’t feel the need at any point to defer to a vivid picture setting. That said, the standard setting isn’t at all unrealistic. In short, images are pleasing.

We took the Panasonic S1 for a trip (and a stumble) behind a waterfall at one point during our review period, whence it was liberally covered in fine spray. As expected the camera kept functioning perfectly, its splash proofed exterior coming into play. At times that these we found a busy moving background could confuse the auto focus into focusing on that rather than the subjects stood in front of it. No matter, it is easy enough to slide the switch on the lens barrel to manual and focus that way, an enlarged portion of the shot helpfully provided on-screen to help us determine what we wanted to be pin sharp in our frame, actually was pin sharp.

In terms of low light shooting, an almost exhaustive incrementally selectable light sensitivity range is provided here, expandable from ISO50 up to ISO204,800 (otherwise we’re looking at a core range of ISO100 to 51200). Again, quality is really impressive. Even at maximum whack, images don’t deteriorate to the extent that they look like crude cave paintings.

Undoubtedly having a large full frame sensor for this camera, a sizeable lens mount, and sensible resolution has worked very well in tandem.


There are 13 ISO settings available on the Panasonic S1. Here are some 100% crops which show the noise levels for each ISO setting for both JPEG and RAW files.

The Panasonic S1's maximum shutter speed is 60 seconds and there's also a Bulb option for exposures up to 30 minutes long, which is excellent news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 30 seconds at ISO 200. The camera takes the same amount of time again to apply noise reduction, so for example at the 30 second setting the actual exposure takes 60 seconds.



Post Focus and Focus Stacking

Post Focus is a function that enables you to select the in-focus area after shooting simply by touching it on the LCD screen. The first three images show the effects of switching between the three memory cards.

The Post Focus > Range Merging function then allows you to combine all or selected focus areas into one image. The fourth image below shows the effect of merging the first three images into one stacked image with the range set between the front and rear memory cards.

Panasonic's Photo Styles are preset combinations of different sharpness, contrast, saturation and noise reduction settings. The 9 available Photo Styles are shown below in the following series, which demonstrates the differences. There are also some Custom options so that you can create your own looks.
