The Powershot G15 was announced at the same time as the SX50 HS in September 2012. The two cameras are targeted at different markets, the G15 with its 5.2-26mm f1.8-f2.8 lens (35mm equivalent 28mm – 140mm), is aimed at the advanced amateur wanting a neat camera to use day to day probably as a supplement to an SLR system. The SX50 HS is more of a high-end consumer compact, a camera that will fulfill all the requirements that its owner might have. Having said that the performances of their respective sensors come as quite a surprise:
The G15 is equipped with a sensor 20% larger than the SX50 HS, something that the more discerning photographer might well be looking for. Yet the results for DxOMark’s testing gives the advantage overall to the cheaper camera. Color depth is 0.4 bits higher on the SX50 HS (20.3 bits against 19.9) and low light the results are virtually the same (179 ISO against the G15’s 165) Only the score for Dynamic range is just better on the G15 (11.5EV over the SX50 HS’s 11.2). The slightly higher overall score may be due to the use of a ‘Back Illuminated Sensor’ a technology that achieves more efficient use of the surface area’ would be better. There are some features where the G15 has the edge, it has a slightly larger but much higher resolution display, wider apertures, higher shutter speeds, a more powerful flash and it is smaller and lighter.
However the SX50 HS fights back with its immense zoom range, a fully articulated display and a slightly faster continuous frame rate. When you consider the price too the SXZ150 HS looks very attractive.
While the comparison with Canon’s own G15 is interesting, it is not comparing like with like. To do that we need to look further afield: Panasonic’s Lumix DMC-FZ150 is a much closer match.
The Lumix is fitted with a lens that goes from 4.5mm up to 108mm (a 35mm equivalent of 25-600mm), exactly half the range of the Canon. However, it does have a 4x digital zoom, twice what the Canon has so the total range is the same. In many other respects the Lumix and the Canon are very similar, but there are several features where the Lumix just beats the Canon. The Lumix has a bigger display: 3” and more AF points: 23 against 9, it has a slightly higher frame rate and the ability to shoot 3D images, but otherwise the two have near identical specs. DxOMark’s testing shows that the similarity is only superficial. The Canon SX50 HS scores 47 overall whilst the Lumix DMC-FX150 scores only 40.
Nearly a full bit of extra color depth, over a third of a stop of dynamic range and a similar amount of low light performance for the Canon demonstrate the all round advantage that it has over the Lumix. All of this comparison points toward the Canon as the more accomplished camera, but the big surprise is that it is also significantly cheaper, roughly 25%. This is a comparison of the quality of the data produced by the sensor, not of the lens quality but based on this alone the Lumix has quite a fight on it’s hands.
Panasonic has launched a replacement, the Lumix DMC-FZ200. The specifications for this new camera appear to be very similar to the DMC-FZ150 and DxOMark will be testing it soon to see if it closes the gap with the PowerShot SX50 HS. It will still retail at a higher price than the Canon so it will need to be good to beat it.
