Dwarf galaxies stripped of stars prove to be the missing link in the formation of rare ultra-compact dwarf galaxies
ultra-compact dwarf galaxies, objects with masses much greater than star clusters yet much smaller than dwarf galaxies. These findings confirm that many ultra-compact dwarf galaxies are likely the fossil remains of normal dwarf galaxies that have been stripped of their outer layers.

Dwarf galaxies stripped of stars prove to be the missing link in the formation of rare ultra-compact dwarf galaxies

Astronomers using the Gemini North telescope, one-half of the International Gemini Observatory operated by NSF's NOIRLab, have captured the eroding remains of more than 100 dwarf galaxies as they transition into ultra-compact dwarf galaxies, objects with masses much greater than star clusters yet much smaller than dwarf galaxies. These findings confirm that many ultra-compact dwarf galaxies are likely the fossil remains of normal dwarf galaxies that have been stripped of their outer layers.

Nikon Reveals The Affordable Z-Mount 40mm f/2 Compact Prime Lens

Nikon has announced the $300 Nikkor Z 40mm f/2 Ultra-Compact prime lens. The company claims the new optic will provide extraordinary bokeh and fantastic image quality for both video and still photos, all in a very tiny package.

Nikon says that many creators have told it that they want extremely small lenses with fast apertures to compliment the lightweight Z series mirrorless cameras, and the new 40mm f/2 will deliver on that request in a lens that it says is great for travel, street photography, and everyday use.

The company says that the 40mm f/2 prime lens is versatile and can be used on any of the Nikon Z series full-frame or DX (Crop sensor) format cameras since it is small enough to sit discretely on a Z 50 or Z fc, but still suitable when paired on a Z6 II or Z7 II for users seeking something light and compact as a "walk-about" lens. It is worth noting that when paired with a DX system the lens is equivalent to 60mm, making it a great focal length for portraits.

The new lens is built with six elements in four groups and features a nine-blade electromagnetic diaphragm for precise aperture control and stable exposures during continuous shooting. This is all packed into a lens body that is only 1.8 inches in length and weighs just 170 grams, making it a lens you can actually carry in your pocket. The company boasts the f/2 aperture will give impressive low-light performance while providing exceptional bokeh for great separation between the subject and the background of the images.

Additionally, the lens features a short 0.96 foot (0.29 meter) minimum focusing distance making it suitable for shooting products, food, and beverages that require a "top-down" setup. On top of this, the new 40mm f/2 lens is also weather-sealed to prevent dust and water from entering the lens, features an integrated control ring that can be customized to adjust multiple settings, and the focus motor adjusts smoothly and quietly further proving its utility for video shooters.

Below are some sample images captured with the new 40mm f/2 ultra-compact prime lens:

The new Nikkor Z 40mm f/2 ultra-compact prime lens will be available to order later this fall for $300.

Small, compact, and fast

Tokina’s 400mm f/8 Reflex Lens Now Available for Canon RF and Nikon Z

Tokina has announced that its SZX Super Tele 400mm F8 Reflex MF lens that was originally announced in July of 2020 for Canon EF, Nikon F, Sony E, Fuji X, and Micro 4/3 mounts is now available for Canon RF and Nikon Z.

As reported by The Digital Picture, Tokina made the announcement of the two additional mirrorless mounts on its website.

This lens uses a somewhat unusual mounting method that Tokina seems to have adopted to allow it to easily work for a wide range of mounts without having to specifically adjust the optical portion of the lens each time. It also makes the lens more versatile. It uses a T-mount standard (pitch 0.75mm, thread 42mm), that allows this lens to be attached to various cameras by using different mount adapters, and this announcement is more specifically stating that Tokina is releasing RF and Z-mount adapters that work with the main lens portion.

Theoretically, a photographer could buy one of the 400mm f/8 reflex lenses and multiple adapters to use the one lens with different brands. For example, a hybrid shooter who prefers to use Sony E-mount for stills and a Micro Four Thirds GH5 for video would be able to buy just one main lens and two adapters and the lens would be compatible with both cameras.

Tokina

A photographer would also be able to easily bring this lens with them should they choose to leave one manufacturer for another, such as jumping from Canon EF to Sony mirrorless.

Tokina says that it will be selling the mount adapters bundled with the 400mm f/8 lens, but also that each of the mount adapters is available to purchase separately as well, which further indicates that the company has this kind of unique versatility in mind.

Reflex lenses, also called mirror lenses, are more commonly found for telescopes than for cameras. These types of lenses use what is called a "catadioptric" design, which combines mirrors and refracting elements into a single lens. This allows engineers to literally “fold” the optical path and magnify the image, shrinking the size of super-telephoto lenses by as much as four or five times while simultaneously getting rid of chromatic aberration almost entirely.

Tokina SZX SUPER TELE 400mm F8 Reflex MF is a 400mm super tele lens that adopts catadioptric type optical design with a constant F8 aperture. The lens offers a compact alternative to standard telephoto lenses as more and more photographers are looking for easy-to-carry gear. 400mm F8 Reflex MF is designed keeping in mind active travel photographers seeking outdoor landscape, wild nature, or birds by providing a compact and lightweight lens to be rediscovered in the new era of also compact but high-tech mirrorless cameras.

The downside of these types of lenses, and why they have dwindled in popularity over the last few decades, is that the design does not allow the lens to have variable apertures (and the aperture tends to be quite small), and they cannot integrate any kind of optical stabilization. Also, the bokeh has a sort of donut shape to it, which is seen by many as unattractive:

Tokina

However, on-sensor stabilization has become much more common over the last few years and modern image sensors are capable of performing much better at high ISOs, making the closed down aperture significantly less of an issue. Since this lens weighs just 340g and measures just 77mm (3 inches) long, the tradeoffs to get such an easy-to-carry optic may very well be worth it now.

Tokina

The Tokina SZX Super Tele 400mm F8 Reflex MF lens is available for $250 for Canon EF, Nikon F, Sony E, Fuji X, and Micro 4/3 mounts now, with the Canon RF and Nikon Z mount adapters joining the group on May 7, 2021.
