Well, it seems that Sony isn’t the only one with a global shutter CMOS announcement of late. According to a press release, Panasonic has also just announced a new global shutter CMOS sensor. This one, though, is capable of shooting up to 60 frames per second at 8K (36MP) resolution. Unlike Sony, which utilises a rear illuminated design with parallel DA converter, Panasonic’s uses an organic photoconductive film (OPF) to allow simultaneous readout of all the pixels on each frame.
Have you ever wondered why camera lenses produce a circular image circle (in general) but sensors are rectangular? Of course the answer is mostly historical – the format of a 35mm photo is in 3:2 aspect ratio, a ratio that people have long known to work well due to human binocular vision.
But lenses, in general, are circular. they produce an image circle, a circle that, in general, allows the 35mm sensor to just fit inside it. You don’t want your image circle much bigger than this (except for tilt-shift lenses) because that makes your lenses heavier and more expensive.
Well, this is a surprise and not an unwelcome one. Few people seem to realise that as well as being a leading 3rd party lens manufacturer, Sigma also make cameras. I have actually had the pleasure of playing with a Sigma sd Quattro for the past few weeks, and it’s pretty impressive if a little on the slow side. The Foveon sensor does produce some truly beautiful results.
That lack of speed, though, has put off many potential Sigma camera owners. Now, a new patent has been filed showing that Sigma looks to be doing something about it. The patent seems to aim more toward the video side of things but no doubt it will speed up its stills capturing capabilities, too. Perhaps this is why Sigma semed a little evasive about camera questions recently at PPE.
Just 20 days ago, Nikon D850 was crowned the best DSLR ever, according to DxO tests. It was the first camera to reach the overall score of 100, but now there’s a new winner. Hasselblad X1D-50c, medium format mirrorless camera, has won the overall score of 102. According to DxO, it’s now the best commercially-available medium-format sensor you can get. If medium format is what you’re looking for.
One of the biggest pieces of D850 speculation floating around the Internet the last few days seems to be about the sensor. Specifically, who makes it. And no, it’s not Sony. Nikon have actually designed their own sensor for the D850, according to a Q&A session with Imaging Resource. Nikon also promise some pretty significant performance improvements.
This isn’t the first time Nikon have developed their own sensor. Although, many of their past cameras have used Sony and a few Toshiba sensors. But it a Nikon designed sensor is a first for the D8x0 line. The D800 and D810 both contain a 36MP Sony made sensor suspected to be the same one as that in the original Sony A7R.
We all harp on about the latest 4K this or 8K that. But do we really know what we’re saying? Most of the time, probably not. It all comes down to how the camera’s sensor actually records each of those pixels in the image, which is largely guesswork.
In this video Cooke Optics interview cinematographer Geoff Boyle. He explains that it’s basically all down to the nature of a Bayer pattern filter array. What’s really happening when your sensor sees an image and why your camera’s resolution is lying to you.
It’s amazing how far sensor technology’s come in the last few years. We’ve had dual pixel autofocus, ultra high ISOs, and a whole bunch of other cool features show up. Phones and bigger camera sensors get more and more powerful with each new generation. This sensor from Sony, though, might be one of the most exciting yet.
Sony have developed a way to speed up the data acquisition in a CMOS sensor. It doesn’t quite make it a global shutter, but it speeds things up enough to be almost as good, but at a much lower cost. The acquisition becomes so fast, it’ll even record full HD 1080p video at up to 1,000 frames per second. The technology seems destined for smartphones at the moment, but I would bet it won’t be too long before it scales up.
While some companies are trying to make the sensors in their cameras bigger, Sony are doing the opposite. They’re going smaller. Really small. Their new 2mm sensor is capable of a single megapixel, 1,296 pixels along the longest edge. Paired with a 2.6mm lens, the circuit that connects the whole thing to a device is also extremely tiny. The 20 pin connector is shrunk down to a minuscule 3.3mm. And the whole setup weighs just a tenth of a gram.
This sort of sensor isn’t all that useful for the handheld cameras most of use, but it does hold a lot of possibility for very small devices. Like smartwatches. These typically don’t contain any camera at all. Not even a front-facing one for things like Skype or Face time. Sony say the new sensor also boasts very low power consumption. So, it’s something that many smartwatch owners have been waiting for.
Looking to make your own DSLR camera trap housing? You’ve come to the right place. Camera trapping is an increasingly popular technique, and it’s rather addictive too. The ability to leave your DSLR camera out for days or weeks at a time, watching and waiting 24 hours a day, has revolutionised the wildlife photography field. Now it is possible to take photos of rare animals, such as jaguars or leopards, at night. But it doesn’t need to be a big cat, as camera trapping can be used even in your own back garden with the likes of foxes and badgers.
But if you’re going to leave your camera out and exposed to the elements, then you need to build yourself a DSLR camera housing. This tutorial will look at the best way, trusted by almost all camera trapping photographers to date, to build your housing. Watch our video tutorial below, and refer to the rest of the article for more specific guidance.
Photokina 2016 is just four months away and already rumors are swirling around as to what we can expect from photography companies at the world’s leading imaging expo.
One of the latest rumors says Sony is looking into creating a medium format imaging sensor to take on the likes of Hasselblad.[Read More…]
