The fourth small camera I recently checked out was the Nikon 1 V3, the third with a 1" sensor.
What is really interesting about this camera is its high frame rates (10 fps RAW with full exposure for each frame, 20 fps RAW if the exposure for the first frame is repeated).
In addition, Nikon makes a pretty decent 70-300mm f/3.5-5.6 CX lens for this camera, which delivers an effective reach of 189-810mm. So potentially, this is a very nice solution for action and wildlife photography, far more practical than a DSLR with a behemoth super tele or mega zoom lens.
This is an option that my flickr friend Eric and I have been discussing for some 18 months now. I was not very impressed by the specs of the Nikon 1 V2, but the V3 made it more interesting, and I finally decided to take it on a test drive.
After shooting over 500 images, I returned the camera and the lens, for the reasons below.
First, the noise becomes unusably excessive beyond ISO 400. Even ISO 800 smears all sharp edges, wiping away micro contrast. With a lens with a max aperture of f/5.6 at the long end, being also limited to a max usable ISO of 400 makes it tough. At ISO 800-1600, to get sharp images, you'd have to downscale the files to a 2-4MP resolution. Just not good.
Second, even in good lighting and low ISOs, the lens cannot quite resolve the 18MP the sensor has to offer, at least not at the long end. It is a little better at the wide end. I don't know if it's a limitation of the lens, or if the noise is high enough even at low ISOs to cause smearing and a loss of micro contrast. If I can get crops from an A7R-ii with superior image quality, so why bother with the V3 at all?
Third, the V3 is a ludicrous camera design. I can't believe a major camera maker would go to market with such a Mickey Mouse design. Here are just some of the issues:
– It has a comical add on EVF, while a myriad of other cameras like the Sony RX100, Panasonic LX100, etc. have a built in EVF.
– It uses a micro SD card which needlessly complicates the handling, when much smaller form factors like the Sony RX100 use full sized SD cards.
– It has a ridiculous add on grip that goes over the existing grip. While the add on grip improves the handling of the camera, it is a pain to put it on – it has four protrusions that need to stick into the body of the camera, three of which push in and the one in the middle is a screw. It is very difficult to mount this on the camera if the base plate is not perfectly lined up with the bottom of the camera. And this has to be taken out to access the battery.
– Nikon sells the V3 as a bundle with a crappy 27-81mm equivalent f/3.5-5.6 kit lens, and forces you to buy this combo for some $250-300 more than what just the body should cost.
– The camera looks and feels really cheap and plasticky.
– A lot of other smaller PITA issues that I won't bother to get into.
Bottom line: a poor design, terrible usability issues, forced bundling and an obsolete sensor, leading to low image quality. Pass on it.
Having pointed out a lot of negatives, I should also mention that the camera is very impressive in two areas: AF tracking in the machine gun mode, once it has acquire focus (although it misses quite a few frames in the middle), and superb image stabilization. The camera does frequently struggle to acquire that initial focus, however.
So the camera has some potential. If / when Nikon comes out with a more competently designed V4 using the new 1" stacked CMOS sensor from Sony, with much better ergonomics, I would give it another try, because the 70-300mm CX lens has a lot of potential.
Some test shots follow.
Despite some "sensor noise graininess," this one is worth a LARGER VIEW for the colors. This was shot from a moving ferry in light fog and rain in Hong Kong's Victoria Harbour.
Extreme conditions: periodic clouds, light pollution from the streets LED lamps, a lens developed to a small sensor attached in a camera with larger sensor, producing strong vignetting (1-inch sensor lens in an APS-C Fuji's camera), severe post-processing crop and so forth.
In the previous test with this lens the result is very bad in my opinion but in that time I didn't do a good review.
In Adobe Camera RAW the histogram was in the extreme right side in the base ISO 200 (exposure to the right) although the aperture two f-stops closed (from f/0.95 to f/2) and 8 seconds exposure time.
Of course, a lot of light came from urban area, including that one reflected by the clouds.
In the stacking process I have utilized only 25 frames without calibration ones.
The image result was clean!
The severe crop have solved the problem about the strong vignetting - the area of the sensor where no light is present - and star aberrations near the borders no compromising the image quality significantly.
The base ISO provided better star colors and we can distinguish the orange and blue stars in the image.
Conclusions:
Schneider-Kreuznach Xenon 25mm f/0.95 is a "jewel" in terms of optics.
The only flaw is not related to the lens but to the camera sensor size unespecific to it.
Probably I will have better results in a camera with 1-inch sensor size ou smaller (2/3 inch for example).
Lens distorsion is very low compared to other ones with the same or similar focal length.
Star aberrations have the same pattern of the urban lights at night street photography. In fact, aesthetically is very bad in f/0.95 even at the center of the image. In an one-inch sensor this condition won't be different. Unusable!
Targets as Barnard's Looping is very difficult in these climate conditions and urban area with severe light pollution.
Probably in a darker area, distant from the urban center, the colors of this nebula would can be bring in the post-processing easily.
Veredict: Wonderful lens in the specific sensor to which it was developed.
A simple, quick, and very cheap circuit to turn on an LED when it gets dark. Read more about this project here.

In a retired jet at Sandia, Dennis Roach and Ciji Nelson prepare Structure Health Monitoring (SHM) Sensors.
The Comparative Vacuum Monitoring sensor is a self-adhesive rubber patch, ranging from dime-to credit-card- sized. The rubber's underside is laser-etched with rows of tiny, interconnected channels or galleries to which an air pressure is applied. Any propagating crack in the materials under the sensor breaches the galleries and the resulting change in pressure is monitored. The sensors are made by Structure Monitoring Systems, Inc. (SMS) of Australia, are inexpensive, reliable, durable, and easy to apply. They provide equal or better sensitivity than is achievable with conventional inspection methods. Besides aircraft, SHM techniques could monitor the structural well-being of spacecraft, weapons, rail cars, bridges, oil recovery equipment, buildings, armored vehicles, ships, wind turbines, nuclear power plants, and fuel tanks in hydrogen vehicles.

Sensor in original position was reading approx 5 degrees higher than ambient. Re-positioning resulted in correct temperature readings.

For those who've wondered at my probably annoyingly often references to the damage to my camera, here it is in all its glory.
The only reason I'm sharing this is because of the amazing flare my 10-20mm produced here.
Do you clean your own sensor? I bought the MARUMI Low Pass Filter Cleaning kit which I will attempt to use next time I have dust on the sensor. Getting tired of having the camera shop do it.

Quick splash in the dishwasher a wee massage with a towel and put it all back together and get lovely crisp shots ... Thanks Google !
This is the sensor pcb module. An AVR controller ATtiny45 take 50.000 ADC samples/sec and give the results to the CPLD module. Into 40 usec detection from a fast flying insect in focus is possible. This module commes into the AF200/4Dmicro lens from Nikon. Only insects in focus give a signal output to the CPLD module.

In many fatigue assessments characterising the applied service loading is the most difficult and critical step.
Fatigue Integrity Management has over fifty years experience in the design and installation of systems to allow in-service load or stress spectra to be established through acquisition and analysis of load, strain and displacement records.
CrackFirstTM sensors provide an alternative long term system for fatigue usage monitoring on steel structures. Attached adjacent to a fatigue critical detail, the sensor responds to cyclic loading by changing its output in proportion to the cumulative fatigue damage for a typical fillet welded joint. The sensors allow an estimation of remaining life of the structure and safe usage-based inspection intervals.
A wide range of structures and components has been assessed for TWI Members including earth moving equipment, road trucks and tankers, bridges and pressure vessels.
TWI operates a quality assurance scheme certified to ISO 9001:2000 by LRQA and BS EN ISO 14001:2004
and is an IiP certified company.
