M.Zuiko Digital ED 40-150mm F4.0 PRO named the lightest and most compact zoom lens with a constant maximum aperture and a focal length range including 300mm EGF
Along with the M.Zuiko Digital ED 12-40mm F2.8 PRO II lens, OM Digital Solutions introduced the M.Zuiko Digital ED 40-150mm F4.0 PRO lens. According to the manufacturer, the Olympus M.Zuiko ED 40-150mm f2.8 Pro, released in 2014, served as the starting point for the design of this telephoto lens. Note that the optical schemes of the two models are different, so, unlike the mentioned M.Zuiko Digital ED 12-40mm F2.8 PRO II, the M.Zuiko Digital ED 40-150mm F4.0 PRO lens is a completely new product. Claimed to be the lightest and most compact zoom lens ever, with a constant maximum aperture and a focal length range that includes 300mm EGF.
Technical data of the M.Zuiko Digital ED 40-150mm F4.0 PRO lens:
- focal length – 40-150 mm (EGF 80-300 mm);
- aperture – f / 4-f / 22;
- number of aperture blades – 7;
- optical design – 15 elements in 9 groups, including 2 aspherical elements, 2 ED elements, a Super ED element and an HR element;
- minimum focusing distance – 0.7 m;
- maximum magnification – 0.21x;
- focusing – automatic (using a stepper drive) and manual;
- filter installation diameter — 62 mm;
- diameter – 69 mm;
- length – 99 mm;
- weight – 382 g.
The lens is supplied with lens hood LH-66E. It costs $900 and should go on sale in early March.

A “completely silent” 1300W power supply. Cooler Master showed two new products, but only the youngest received a passive CO

Cooler Master brought power supplies to Computex that they claim are absolutely silent.
The younger model with a power of 750 W is really silent, because it simply does not have a fan. By the way, this is the company’s most powerful power supply with passive cooling.
There is also a 1300W PSU. It has a fan, but Cooler Master also calls it completely silent.
The secret to successfully cooling such powerful PSUs without too much noise lies in the use of an evaporation chamber. There are no other details yet, as well as no pricing data.

NASA SLS launch vehicle over budget by $6 billion and six years behind schedule

NASA’s SLS super-heavy booster is already over budget by $6 billion and six years behind schedule, according to a recent report.
A recent report generated by the NASA Inspector General’s review indicates that NASA’s spending on the Artemis program will reach $93 billion by 2025, including the $23.8 billion already spent on SLS through 2022.
Despite a successful first run earlier this year, the Inspector notes that the project involves additional costs and a further shift in the schedule. Moreover, if the existing problems are not resolved in time, this may jeopardize the entire mission of Artemis.
As for delays, out of the six years mentioned, five years of delay, and at the same time an additional almost $ 2 billion, fell on Northrop Grumman accelerators. The bottom line is that the SLS project initially involved the partial use of old equipment from the days of the Space Shuttle program. Of course, with the necessary upgrades. Northrop Grumman boosters were one such element.
The inspector blames the situation on the cost-plus pricing method and recommends switching to fixed prices. In general, NASA agreed with all eight of the inspector’s recommendations.

Exynos platforms will appear in a new type of device. Samsung to create SoC for mixed reality headsets

Samsung is going after Apple to release its mixed reality headset. The device will be released either at the end of this year or early next. There are no details about it yet, but it is reported that Samsung is also going to release its own Exynos single-chip systems for headsets.
Considering that these are only plans for now, the upcoming Samsung headset will apparently either rely on some foreign platforms or on existing Exynos SoCs.
However, new platforms for mixed reality headsets may not be entirely new. It is reported that Samsung has not yet decided whether it will develop these SoCs from scratch or simply adapt existing solutions.
