Nikon announces entry-level D3400 DSLR camera, 2 telephoto lenses

first_imgAlmost after two years, the Nikon D3300 has been replaced. But if in case you are a D3300 users, don’t feel jealous of the D3400. Despite a long time in making, Nikon’s latest entry-level camera D3400 is more or less the same as the D3300. The big changes are in design and addition of an always-on Bluetooth sensor that will help users connect the camera to their smartphones.The D3400 will be available in India from the last week of September. For now the India price of the camera has not been announced but expect it to be around Rs 35,000.In addition to sporting an always-on Bluetooth sensor, the D3400 is also lighter than the D3300 as well as promises better battery life (around 1200 shots). But other than these minor changes, not much is different. the new camera has the same 24-megapixel sensor that is inside the D3300 and it has the same focus system. It also has the same image processor and hence similar shooting speed. The ISO range now goes to 25,600 compared to the 12,800 of the D3300. However considering the fact that the image sensor is same, it looks like Nikon is using some software tweaks and optimisations to get better low-light performance in the D3400.Although, somewhat disappointing, it is also understandable why Nikon made the D3400 in the mirror image of D3300 and kept the hardware more or less same. The 24-megapixel sensor inside the D3300 is one of the best ever seen in an entry-level camera. It is great at dealing with dynamic range and the fairly spot on when it comes to colours. It also lacks the low-pass filter, which helps it capture more details.advertisementThe D3300 sensor is not only good when compared to what went into the previous Nikon cameras, it also has a huge leap over sensors in Canon’s DX cameras. May be lack of competition at the low-end meant that Nikon could take it easy with the D3400. The D3400 will be sold with a 18-55mm kit lens.Two new lensesOn Wednesday, Nikon also announced two new lenses for DX camera shooters. These are 70-300mm f/4.5-6.3G ED and AF-P DX NIKKOR 70-300mm f/4.5-6.3G VR.As the name indicates, these lenses will work with DX cameras like the D3400. They won’t work, or work properly, with the FX cameras like the D750. Also, one of these lenses have the VR (vibration reduction) which is useful while shooting closer to the higher range of zoom. These two lenses are aimed at shooters who want to click images wildlife. When used with the DX camera, their effective focal length would be around 450mm.The two new lenses will also be available in India in the last week of September. Nikon will reveal the prices of the lenses closer to their availability although the prices to be on the lower side. The company already has a 70-300mm lens for FX and DX cameras that costs over Rs 30,000 and it has an excellent 55-300mm lens for DX cameras that sells for around Rs 20,000. Considering these two already existing lenses, it is possible that these new lenses may cost around Rs 15,000 in the market.Also read: Best cheap DSLR camera: Nikon D3300.

NASA telescope discovers three intriguing planets hiding around nearby star

This “super-Earth” is called TOI 270 b. Don’t expect to send colonists there. NASA described it as “oven-hot” thanks to its proximity to its star.   The other planets, TOI 270 c and TOI 270 d, are likely closer to gas-giant Neptune in makeup. “Planet c and d might best be described as mini-Neptunes, a type of planet not seen in our own solar system,” said NASA.toi270-infographicEnlarge ImageThis NASA infographic shows how TOI 70’s planets compare to Earth. NASA’s Goddard Space Flight Center/Scott Wiessinger The exoplanets’ discovery is just the start. “TOI-270 will soon allow us to study this ‘missing link’ between rocky Earth-like planets and gas-dominant mini-Neptunes, because here all of these types formed in the same system ” said Maximilian Günther, lead author of a paper published in the journal Nature Astronomy on Monday.TESS launched in 2018 and has been on a roll with exoplanet finds, including spotting a planet with three suns.Astronomers plan to take another look at TOI 270 after NASA’s next-generation James Webb Space Telescope launches, hopefully in 2021. TESS is great at spotting exoplanets of all kinds, but what we’re really excited about is finding planets that may have liquid water and could potentially support life. Don’t count TOI 270 out on that front. There may even be more planets in the system waiting to be discovered.  NASA Space Share your voicecenter_img 0 Now playing: Watch this: TESS before launch. NASA NASA’s Transiting Exoplanet Survey Satellite (TESS) just scored another science triumph with the discovery of three fascinating planets hanging out at a nearby star. One is a super-Earth, slightly bigger than our own planet. The other two are Neptune-like exoplanets, the likes of which you won’t find in our own solar system.The star is known as “TESS Object of Interest 270,” or TOI 270 for short. Its more formal name is “UCAC4 191-004642,” but that’s a mouthful. The star is 40% smaller than our sun and is also about a third cooler. It hangs out 73 light-years away, which qualifies it as a neighbor.  Sci-Tech Originally published July 29, 10:39 a.m. PT 27 Photos This satellite could find alien lifelast_img read more
