Image Quality

All of the sample images in this review were taken using the 12 megapixel Fine JPEG setting, which gives an average image size of around 5Mb.

Directly from the Panasonic Lumix DMC-TZ70, JPEG images are warm and bright, without the tendency to oversaturate as seemed to be a problem with the TZ60.

Detail is also good, and despite the reduction in pixel count, the overall impression when looking at images at normal printing and web sizes is great. Looking at images a little more closely, at 100%, reveals a little image smoothing, even when shooting at low sensitivities, such as ISO 200.

If you shoot at higher sensitivities, that image smoothing gets worse, starting to become visible even when viewing at smaller sizes. Although there is a maximum ISO setting of 6400, it’s generally advisable to stick to 1600 or below if possible. One result of this image smoothing is that noise doesn’t start to become problematic until around ISO 3200. Of course, if you want to control your own noise levels, and bring back some more detail, you can shoot in raw format and do your own processing later on.

The Panasonic Lumix DMC-TZ70’s all-purpose metering system does a good job in most conditions, helping to produce an accurate image - as does the automatic white balance system. Switching to the Incandescent white balance setting can be beneficial under artificial lighting where sometimes the TZ70 will render a scene a little on the warm/yellowish side.

At the far reach of the telephoto optic, images remain pleasing. The Panasonic Lumix DMC-TZ70’s optical image stabilisation system does an excellent job of helping to keep images blur-free even when using the camera handheld, which is great to see. The Intelligent Zoom is there if you need it, but it’s not particularly recommended unless you’re desperate for some extra reach that the 30x can’t give you.

Noise

There are 8 ISO settings available on the Panasonic Lumix DMC-TZ70. Here are some 100% crops which show the noise levels for each ISO setting.

Sharpening

Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are a little soft at the default sharpening setting and benefit from some further sharpening in a program like Adobe Photoshop. You can change the in-camera sharpening level via the Picture Adjust menu option.

Focal Range

The Panasonic Lumix DMC-TZ70's 30x zoom lens provides a very versatile focal length of 24-720mm in 35mm terms, as demonstrated below.

Chromatic Aberrations

The Panasonic Lumix DMC-TZ70 handled chromatic aberrations well during the review, with some purple fringing present around the edges of objects in certain high-contrast situations, as shown in the examples below.

Macro

The Panasonic Lumix DMC-TZ70 offers a Macro setting that allows you to focus on a subject that is 3cms away from the camera when the lens is set to wide-angle. The first image shows how close you can get to the subject (in this case a compact flash card). The second image is a 100% crop.

Flash

The flash settings on the Panasonic Lumix DMC-TZ70 are Auto, Auto/Red-eye Reduction, Forced On, Slow Sync./Red-eye Reduction, Forced Off. These shots of a white coloured wall were taken at a distance of 1.5m.

Night

The Panasonic Lumix DMC-TZ70's maximum shutter speed is 60 seconds, which is great news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 1.6 seconds at ISO 200. The camera takes the same amount of time again to apply noise reduction, so for example at the 15 second setting the actual exposure takes 30 seconds.
