Voigtlander Apo-Skopar 90mm f / 2.8 SL II S lens for Nikon DSLR cameras

Published

on

Along with the Voigtlander Apo-Skopar 90mm f / 2.8 VM lens equipped with a Leica M mount, the Voigtlander Apo-Skopar 90mm f / 2.8 SL II S lens for Nikon SLR cameras has appeared in the Cosina catalog. These products are built according to the same optical scheme, but outwardly they differ markedly. The version with the Nikon F mount is one and a half times shorter than the version with the Leica M mount, but slightly larger in diameter, weighs a little more and is designed for filters with a diameter of 52 mm, not 39 mm. In addition, its diaphragm has nine rather than ten blades. The lens for Nikon cameras is equipped with a processor and can transfer data to the camera for recording in EXIF. The hood, unlike the version for Leica cameras, is not included in the kit.

The rest of the lenses are similar. The Nikon F mount is also suitable for full-frame cameras and focuses manually. The apochromatic optical scheme underlying it, according to the manufacturer, made it possible to reduce chromatic distortion to almost zero. In addition, the manufacturer notes that “the focus ring and aperture ring are made of metal, and the precise knurling pattern and large finger notches not only create a sense of aesthetic pleasure and nostalgia, but are also functional, enhancing the feel of manual control.”

Voigtlander Apo-Skopar 90mm f / 2.8 SL II S technical data:

  • focal length – 90 mm;
  • optical design – 7 elements in 7 groups;
  • aperture – f / 2.8-f / 22;
  • the number of aperture blades – 9;
  • minimum focusing distance – 90 cm;
  • maximum magnification – 1: 8.1 cm;
  • filter installation diameter – 52 mm;
  • diameter – 66.3 mm;
  • length – 41.0 mm;
  • weight – 260 g.

The lens will be offered in two exterior designs. In Japan, sales will begin in November for about $ 595. The LH-90 IIS hood will be available for $ 44. As a reminder, the lens for Leica cameras, complete with hood, costs $ 790.

Apple, Samsung and Xiaomi smartphones cannot do that. There was a video with the disassembly process of the modular Fairphone 4 and strength tests

Published

The modular and most maintainable smartphone Fairphone 4 fell into the hands of blogger JerryRigEverything.

In this case, we are interested not only in his strength tests, although there is usually only one useful of them, but also in the video of the disassembly process.

As you can see, the smartphone is disassembled and assembled as easily as possible, and even the display is dismantled simply by unscrewing a few bolts. There is no need to talk about the simplicity of the battery replacement process. No other device in this segment offers this.

At the same time, modularity did not affect the strength in any way. Thanks to the metal frame, the smartphone practically does not bend, which is very good. The plastic of the back cover does not suffer from this effect either.

Recall that Fairphone 4 is based on SoC Snapdragon 750G and is equipped with an IPS screen, 48-megapixel main camera and a 3905 mAh battery.

Google makes life easier for Android TV owners by adding the ability to install apps from a smartphone

Google has made life easier for Android TV owners. These users can now install applications on their TVs directly from their smartphones.

To install, just go to Google Play from your smartphone and select a TV from the drop-down list as the target for installing the software. Similarly, Google has implemented the installation of applications on smartwatches with Wear OS.

This approach allows, firstly, to install the application faster and easier, since it is still easier to do all the manipulations from a smartphone, and secondly, in this way, you can install the application remotely without being in front of the TV.

Computer in “credit card” format. Qualcomm develops Qompute Card concept despite Intel’s failure

Published

on

Qualcomm is reportedly developing a concept called the Qompute Card.

It involves placing all the basic elements of a PC on one small board. This will allow you to easily and quickly update the configuration of such a PC or use such cards by one user in different places on different PCs. Also, a similar solution can find application in household appliances.

The concept is not new at all. Back in 2017, a similar idea for the Intel Compute Card was presented, but the company abandoned it two years later, since it did not receive any distribution in the market.

Qualcomm as a whole makes a very similar decision, except that the heart of such cards will be SoCs based on the Arm architecture. The Qompute Card will also contain the motherboard, RAM and flash memory. That is, all the main elements of the finished device. At the same time, Qualcomm cards may well be significantly smaller than Intel Compute Card, if only because of the different power consumption of SoC Snapdragon and conventional Intel CPUs.

Qompute Card are aimed specifically at computers and laptops. At least the SoC Snapdragon 7c + Gen 3 presented the other day will also be offered as part of the cards. The source adds that Qualcomm is testing configurations for both Windows Arm and Chrome OS. How successful this version will turn out to be, time will tell. So far, all such modularity initiatives have not met with success.
