The Kentfaith Digital Camera is a budget-friendly option perfect for beginners and casual photographers. It features a 64 MP resolution for sharp images, and 16x digital zoom. The simple design and user-friendly connection make it easy to use, it also has a reasonably sized screen that is great for framing and reviewing shots. However, the camera struggles in low-light places, and the digital zoom can reduce image quality. Even with these drawbacks, it offers good value for its price, making it a solid choice for those new to photography and other beginners. And the fact that it is already provided with a 32GB SD card is good. Overall a great camera.

These are very nice, especially for the price. I’ve used them a lot on film and digital and I have not noticed any color shifting or inconsistent exposure across the frame like you experience with the cheaper variable filters

I compare this to the Bower Digital PL. It's 1/2 the thickness and easier to use because the rotating part has ribs placed around it, giving you a good grip and controlling the polarization. I tested it today and it appears to be completely color neutral and no color fringing like I've seen others do. The price is right and I can only recommend it.

First, I have several different IR night vision glasses/monoglasses that are designed differently than most models. These have an integrated bracket to use them freehand. They are delivered with a helmet bracket and a head holder. I bought it to use them with the head holder. It is fully adjustable and sticks to her head very well. If you do not use it, just fold the bracket upwards and the head holder keeps it out of the way of leveling the IR brightness, a digital increase and reducing, it can take pictures and videos with sound (the sound is very quiet) . It has a manual focus setting to easily sharpen the image you look at when IR switched off this device to digitally improve the image. In the video I clicked through the different IR levels and switched off the IR to show how dark it is outside. Adjust the level correctly so that the image is not hidden, but if the goals are in the dark, however, these can be used as normal handlasses or even mounted on a tripod. They work just as well during the day as a digital binoculars that can be used free hands, they will work well for you.

A microscope can have high magnification, but poor resolution. Racking the microscope from up to down optically projects an ever-smaller portion (field of view) of the specimen onto the microscopes CCD sensor. The result is magnification with increased resolution (limited by the optics and CCD resolution). The up/down buttons on the microscope digitally magnify by selecting a subset of the sensor’s pixels and digitally upscaling them. The image is bigger (magnified), but there is no increase in resolution (like watching SD programming upscaled on a HD set). The pixel density of the display determines the viewed specimen size on the screen. A good analogy is an HD video is much smaller on your phone than on a large-screen HD TV, but both have the same HD resolution. It’s just that the cellphone is smaller with a far greater pixel density. Magnification without increased resolution is sometimes called “empty magnification”. It is fine for soldering circuit boards, but not useful where both magnification and resolution are needed (i.e., cell structure).
I made the following measurements using a slide (w/ mm scale) and measuring the apparent size on the scope’s screen (no zoom):
- High point (Lowest Power): 22mm on slide measured ~90 mm on screen (~4x) with ~23x13 mm FOV
- Low point (Highest Power): 2 mm on slide measured ~90 mm on screen (~45x) with ~2 mm x 1.1 mm FOV
The digital zoom button (up arrow) provides an additional 2x zoom (~90x max on the microscope's display). Displaying the image to a 27” HD display provides ~6x increase in apparent image size, but no increase in resolution. I assume the CCD sensor is HD (1980x1080), but could not confirm.
Images were sharp with good color on the microscope screen. I would rate the build quality as average for the price. The lighting system is good (and adjustable), but could use better diffusers. The gooseneck lights are definitely needed at low focus (high rack). The UV filter is threaded, but attached with double-sided tape. The rack and pinon focuser had a bit of play, but acceptable in this price range. The barrel focuser was a little stiff. Wireless control did not work out of the box, but I was able to move the circuit board to make contact the battery (not included). No PC software was in the box, nor a download link provided; however, the seller did provide link on request. The instruction manual left a bit to be desired – but all-in-all, my initial impression is that it is acceptable for its intended purpose (i.e., viewing objects visible to the naked eye and circuit board soldering).

Easy to install, really obvious setup and the camera seems to be working fine.
However, the night vision is a bit weak. Although it works in the dark, the IR LEDs may be too much for the CCD to manage.
You get a picture but I would defy anyone to pick out details and unless your brickwork is the usual red variety it will swamp. I've decided to put some tape on a coupe of the IR to see if that helps. It could be better if there is a way to dim the IR, but for the price paid it's really a steal. Solar charging works as advertised, even on cloudy days.

There is quite a long latency from camera to screen, I suspect most don't worry about that and detection works well and no false positives (so far).

No X-pattern, virtually no color cast, and a 1-5 stop range (vs. the more common 2-5) make the Kentfaith True Color ND Vario the best variable ND on the market for most situations. Technically, a little extra warmth can be noticed in head-to-head comparisons, but it's almost impossible to tell otherwise and close enough to be matched in post with no ill effects on compressed photos or video.

I wish the IR filtering was implemented in True Color, but perhaps the technology used here doesn't allow for that. Because IR is not filtered, certain lighting conditions can be undesirable or even unusable, especially when more visible light is cut off. Assuming (possibly erroneously) that one flaw is a necessary compromise for the True Color's unmatched color accuracy, I feel the True Color ND-Vario is as perfect as a VND can get, and first VND that doesn't feel like a compromise between accuracy and practicality.

Here's hoping for a true color version of their 5-9 stop next!

K&F Concept 3G/4G camera:
Fantastic picture during the day and at night with white LED or IR. In addition, the camera can actually do without an internet or power connection. Smooth operation when watching the videos. Detected movements are communicated via push.
The software still has room for improvement
