The relatively small 1-inch CX-format sensor found in Nikon’s new mirrorless cameras caused quite a bit of discontent among serious shooters even before the cameras were announced, but now that it’s official we finally have the opportunity to see its image quality in real-world environments. dpreview has published a gallery of 23 JPGs shot with the Nikon J1, along with 5 RAW files shot between ISO 100 and ISO 3200. Take a look, and judge for yourself.
Last year Canon announced the world’s largest CMOS sensor — an 8-inch chip that’s 40 times the size of those found in Canon’s full frame cameras. Now, a year later, the sensor is finally being put to good use, having found its way into the Schmidt telescope at the University of Tokyo’s Kiso Observatory. The extreme-sensitivity of the sensor has allowed astronomers to detect more faint meteors during a 1 minute period than could previously be seen during an entire year, and has the ability to record those meteors at 60fps. Now we’ll just patiently twiddle our thumbs and wait for the sensor to appear in an upcoming digital camera.
Last September, Sony issued a notice informing customers that its pellicle mirror cameras would overheat during extended periods of video recording. Rather than maximum clip lengths, the company’s cameras are apparently limited by how long the sensor can endure high temperatures. In the video above, someone tests Sony’s new NEX-5N mirrorless camera for this overheating issue, and finds that you can record about 23m22s of video from a “cold start” before the camera issues a warning and shuts off automatically (the temperature indicator turns on at 12m23s).
You can supposedly record 29 minutes of footage on the camera if the sensor doesn’t overheat, though that’s probably impossible to achieve under normal circumstances — unless you’re shooting at the North Pole or something…
People seem to be having a hard time swallowing the idea that Nikon could do well if their upcoming mirrorless camera only packs a 2.7x crop sensor, but Thom Hogan argues that there’s a logical “hole” in the market that Nikon could be the first to fill:
So how much change does it take to make a real difference that gets noticed? The number 1.4 is meaningful in photography in so many ways. Turns out, that something around that number makes a lot of sense for capture size change, too. Each 1.4x change doubles the area of light captured. Hmm, that sounds an awful like a “stop.” [...] So if we were to make cameras about a stop apart, what would we get: a progression close to MF, FX, DX, m4/3, and whatever Nikon calls their 2.7x product.
[...] all this discussion that a 2.7x size choice is irrational is incorrect, IMHO. Having three very different choices with clearly different and increasing performance at each size is on its face a rational decision. If Nikon can deliver a stop+ better performance than the best compact camera but keep the overall size close, that represents a gain to photographers.
Though there does appear to be a “hole” in the sensor size progression of existing cameras in the market, whether anyone actually wants a 2.7x sensor remains to be seen — especially as MFT cameras get smaller and smaller.
You might soon be able to control Nikon DSLRs using only your emotions. A patent published recently shows that the company is looking into building biological detectors into its cameras, allowing the camera to automatically change settings and trigger the shutter based on things like heart rate and blood pressure. For example, at a sporting event, the sensors could be used to trigger the shutter when something significant happens and the photographer’s reflexes are too slow. The camera could also choose a faster shutter speed to reduce blurring if the user is nervous.
Nikon has a support page for people who wonder why the company hasn’t added sensor-shift image stabilization to its DSLRs. The first point is that stabilizing the image before it enters the camera allows the user to see exactly what the sensor “sees” through the viewfinder, and allows the autofocus and metering sensors to take advantage of this stabilized image as well. Secondly, they state that they can optimize the system for each lens to achieve finely tuned stabilization that gains extra stops of light over sensor-based systems.
Here’s yet another painful-to-watch example of what the powerful lasers used at concerts can do to your camera’s sensor. This poor soul brought their Canon 5D Mark II to capture some footage, and left with the camera having a new feature: white “framing lines”! Too bad they can’t be turned off…
The pro-level mirrorless camera Nikon is rumored to be working on (the “Coolpix Pro”) may unfortunately boast a not-so-pro-sized sensor. The latest news to be sweeping across the Interwebs is that the camera will pack a 2.6x crop factor sensor, smaller than the Micro Four Thirds format sensor or the APS-C sensor found in the FujiFilm FinePix X100. It’s also likely that the mirrorless camera would have been announced already had production not been stalled by the devastating earthquake and tsunami that struck Japan.
