1. There's no way to get a proper RAW histogram in any digital camera that I know of, they all use the JPEG preview. There are white balance hacks (to ensure unity scaling of each colour channel) and picture style settings (turn contrast and saturation all the way down) that make the histogram look a little more like a RAW histogram would. 2. Both ...

You are correct, it is computed from the JPEG and that makes it harder to tell if you've clipped the shadows/highlights. It doesn't make it less useful though. Most likely both histograms are calculated from a "gamma corrected" image and they will not be able to tell you if you've clipped for sure. The R, G and B channels on your histogram represent the ...

It's called "Nisen Bokeh" and is mainly due to the lens design (though the background plays a part, it's possible to "provoke" this effect with any lens with the right background). Overcorrected spherical aberration (blur disks which are brighter in the periphery than the centre) is usually to blame. It's showing up more often with the A7 due to the use of ...

No: I love my NEX 5T. The kit lens, and the additional 16mm f/2.8 I purchased, are both unremarkable, (I really mean, they are terrible,) but I have a lot of fun, and have had some success, using an old Canon 50mm f/1.8 and and old Sigma 28mm f/2.8 with an adapter. The beauty of the NEX is that with a little practice you can get good results with manual ...

Someone has reported that, speaking with Sony tech support, they were told the voltage limit is 24V. The majority of digital cameras today actually have sync voltage limits higher than you'll find from most online sources, since most online "folklore" about sync voltage limits comes from the botzilla page. What most folks don't realize is that that page ...

What you are demonstrating in your pictures is more of a case of "aliasing" than pixelation. If that's what you mean (the perception that the picture is composed of straight lines rather than proper curves), it happens because of the real time picture resize algorithms the camera uses to display the 24MP images coming from the sensor on the 2MP EVF, and it ...
