Julian Posted February 11, 2013 Share Posted February 11, 2013 According to rumors the upcomping Sony A58 will get a new 20MP sensor. This will probably replace the current 16 MP sensor and I would expect new NEX camera's will also get this sensor (except for the NEX-3N, which will be released soon with the current 16MP sensor). I'm really curious how this new 20MP sensor will turn out. I hope it will be as good, or better, than the Toshiba 24MP sensor in de Nikon D5200 for video. A NEX-5R or NEX-6 replacement with this new 20MP sensor would be great if it is on par with the Toshiba-sensor. Especially combined with the speed booster. adetrybed 1 Quote Link to comment Share on other sites More sharing options...
Rungunshoot Posted February 12, 2013 Share Posted February 12, 2013 But won't this invariably lead to poorer low light performance? I wonder how the D5200 stacks up when compared to the NEX 5n in low light. I have the Speed Booster and it kicks ass...wouldn't want to compromise the low light with unnecessary megapixels.

Julian Posted February 12, 2013 Author Share Posted February 12, 2013 Not necessarily. Over the years sensors get better. The current 16 megapixel Sony-sensor has been around for about 3 years. It has improved since, but it's still based on the same design (I suppose). A new sensor generation can improve both resolution and low light performance. The current 16 and 24 megapixelsensors are much better in low light than the 6 or 8 megapixel sensors the same size from a decade ago.

Administrators Andrew Reid Posted February 12, 2013 Administrators Share Posted February 12, 2013 That's a good question Rungunshoot. I will probably add that comparison to the Nikon D5200 review. So far it is really nice in low light. It will be cleaner (no moire) and more detailed. At ISO 3200 with Speed Booster the NEX 5N might get you more in the shadows though.

Rungunshoot Posted February 12, 2013 Share Posted February 12, 2013 The only thing I don't like about the 5n in low light is the blocky grain structure and soft image at ISO 3200. You can really see the compression and noise reduction working overtime. I really like the grain of the hacked GH2 and RX100. Both those cameras retain fine detail at any ISO. If the D5200 has a sharper grain, that for me would offset a bit of overall luminosity. Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted February 12, 2013 Administrators Share Posted February 12, 2013 Indeed, this is why the GH2 is underrated in low light. I'd rather have a lot of fine grain / noise at ISO 1600 than a lot of blocky noise reduction and less detail at ISO 3200! Quote Link to comment Share on other sites More sharing options...
Bruno Posted February 12, 2013 Share Posted February 12, 2013 I really like the grain of the hacked GH2 and RX100. Both those cameras retain fine detail at any ISO. And the RX100 is a very high mega pixel camera, especially considering the sensor size, so it's very likely that a new sensor could indeed be much better in low light, even with a higher megapixel count.

Rungunshoot Posted February 12, 2013 Share Posted February 12, 2013 Bruno, you're totally right about the Rx100. Excited to see what comes of the new sensors, especially since the NEX-5r and NEX-6 turned out to be steps backward in the video IQ department. I bought the NEX 6 because they reportedly reduced the overheating issue, but aliasing and moire are far more noticeable than the 5n on any fine detail or contrasty edges. I'm returning it.
