Panasonic ZS100 pocket 10x zoom bests Sony RX100 for travel

In 2016, the most portable 10x zoom on a 1-inch-Type sensor is Panasonic LUMIX ZS100 camera (Amazon) (11 oz, 25-250mm equivalent). ZS100 is now my favorite camera which can fit a large shirt pocket. In this impressive 2016 feat of miniaturization, daylit image quality from the 20-megapixel ZS100 can rival all of my cameras used over 34 years through 2012 (beating my cameras up to 4 times heavier, up to 11x zoom range, up to 12 megapixels, at base ISO 100).

Although rival Sony RX100 (of 2015, read my review) is admittedly sharper throughout 3x zoom, Panasonic ZS100 focuses closer at more zoom settings and enormously extends optical telephoto reach. Anywhere from 3x to 10x zoom (70-250mm equivalent), the ZS100 easily beats digital cropping of Sony RX100’s furthest reach (70mm in versions III & IV). ZS100’s good telephoto remarkably expands your capture of wildlife and distant small subjects, more sharply than pocketable rivals or smartphones (see heron photo further below).

Panasonic ZS100 vs Sony RX100 III size

Compare lens and size of Sony DSC-RX100 III with Panasonic ZS100 digital camera. The ZS100 is fatter but can still squeak into a large shirt pocket.

Compare body sizes:

  • 102 x 58 x 41 mm (4.02 x 2.28 x 1.61) Sony RX100 versions III and IV
  • 111 x 65 x 44 mm (4.37 x 2.56 x 1.73″) Panasonic ZS100

Panasonic ZS100 beats macro focus of Sony RX100

ZS100 captures best macro (close focus) when zoomed by 2x, near 44mm equivalent, to minimize excessive corner softness seen at wider angles of view. You must first press the Macro (Flower symbol/left toggle) button to focus closest. In contrast, Sony RX100 III focuses closest only at 24mm equivalent (widest angle of view), lacks a dedicated macro mode, and cannot enlarge subjects as much. Panasonic ZS100 can enlarge small subjects more sharply than Sony RX100.

Because macro was one of my main reasons for carrying an RX100 (to supplement a larger-sensor APS-C system with 11x zoom which captured poor macro), a ZS100 now serves better as our backup travel camera for my wife to carry.

Surprisingly good telephoto sharpness

Carrying a pocket camera with 10x zoom around town lets me capture unexpected moments like this at a distance:

At 250mm equivalent zoom in sunny conditions, the Panasonic Lumix ZS100 camera captures surprisingly good detail in the heron’s head and feathers (portions shown at 100% pixel view). Even the shadowy “Yamaha” letters look reasonably sharp at the edge of the frame. Photographed at ISO 125, f/5.9, 1/1000th sec.

The above overall image (originally 20 megapixels, 5472 x 3648) can be cropped to isolate the heron at 1764 x 1348 pixels, which is enough to print sharply about 7″ high (at 250dpi). Much better than a smartphone camera, Panasonic ZS100 gives you lots of leeway to share digitally cropped telephoto shots on the internet, as in the example below shrunk to 600 pixels high:

  1. Tom, I recently bought a TZ110 (Australian version of the ZS100) for a trip to Canada as backup to my A6300 + 18-105 and 70-300L I use with an adapter. The IQ is remarkably good for a pocket camera, especially with that useful zoom. In the end, I shot 4400 images with the TZ110 vs only 700 with the A6300. And given the results will mostly display as slideshows on a HDTV with the best ones making it to a book of prints, I’ve decided to exchange my ILC cameras for single lens cameras for future trips.
    After reading yours and other reviews of Sony’s RX10iii, I’ve purchased one of those and now determine the future of the A6300. Not jumping into selling it but I can’t see the need to keep both given my photography style.
    Thanks for a very useful and thoughtful website!

  2. Love Panasonic (GH3, GX7, FZ300)…. [and the ZS100 featuring a 1.2-million dot EVF] …is good to know, and I will be taking a closer look at this camera. My main use is shooting actions shots (and video) of surfers at distances of several hundred yards; also birds in flight and the occasional landscape or seascape. This little camera would be the best camera in the world (because I would have it with me) on many occasions. Does it have the usual Panasonic sensor crop (for added reach with no resampling) feature? On the FZ300, this extends the effective zoom from 600mm to 735mm. Thanks for a very nice website – the practical nature of the evaluations and comparisons is very valuable and all too rare.

    • I like that ZS100’s EVF is always available (and doesn’t need to be popped up and down as with Sony RX100 III or IV).

      If you shoot JPEG, try turning on ZS100’s “Intelligent Resolution i.Zoom” feature, giving up to 2x Digital Zoom with “limited deterioration of picture quality” (which supposedly works better than upsizing a crop to 20mp), which would zoom up to 500mm equivalent, JPEG-only (not available when shooting raw file format). I’m not sure if i.Zoom for a JPEG works any better than enlarging an optimized crop from raw file, but Panasonic must have included it for a reason. Personally, I always shoot raw for superior exposure recovery and sharpness optimization; and i.Zoom isn’t available when shooting raw. Turning on i.Zoom may be better than using ZS100’s ordinary 4x Digital Zoom (where enlarging a subset of the sensor’s area to full 20mp decreases picture quality).

      Another form of zoom is the same as cropping in an editor: the ZS100’s “Extended optical zoom” uses respectively smaller JPEG EX Picture Sizes, up to 20x zoom in effect, if shooting JPEG (not raw). Personally, I don’t recommend using EX JPEG sizes, since using the full 20 megapixels is much more flexible, and you can easily crop as needed later in an editor.

      For a camera which fits in your pocket, Panasonic ZS100 is currently the best all-around option, especially if you like telephoto. It’s my wife’s latest travel camera, and serves as backup for me. “The best camera is the one you have with you.” If you can go larger, Panasonic FZ1000 would capture better images due to larger lens diameter. Better yet (but relatively bulky and heavy, 37 ounces) is my Sony RX10 III with 24-600mm equivalent telephoto. — Tom Dempsey

      Thanks for all the additional information and advice. The reason I like the sensor crop zoom is that I can see the subject much better in the EVF. This AM I was shooting surfers who were several hundred yards out (using GX7 with 100-300mm). The extra reach allowed me to tell who was who and get a much better feel for how the wave was shaping up. I always shoot burst mode so as not to miss the best moments, but still it’s always better to have the feel of the wave as you’re shooting. And you end up with 8mp which isn’t bad. (…including a sample 8MP sensor crop shot with GX7 a few months ago… was hazy with flat light so I did do some levels adjustment and minimal sharpening. Without the extra reach of the sensor crop, I couldn’t tell who was who. If you open the full-size image and magnify, you can count the fingers on the hand, see the facial expression, etc..) For days closer to shore the ZS100 might do a pretty good job and with 20mp to work with the end result of a sensor crop shot should be pretty good. I have never liked all the iZoom-type settings – they may have “minimal” degradation but it seems noticeable to me on the cameras I’ve tried. Again, thanks for a great site.

      Tom Dempsey replies:
      That’s great that you can still get 8 megapixels at digital zoom (EX JPEG size, not upscaled), which can still make big prints. The ZS100 is sharper than I expected at 250mm equivalent (for such a tiny camera), especially at center, which potentially makes it useful for your sensor crop zoom technique.
