Samyang unveils their first AF lens for Nikon cameras: AF 14mm F2.8 F [Master the art of Ultra Wide-Angle]
Samyang Optics announces a new, ultra wide-angle lens, the AF 14mm F2.8 F. It is the company’s first-ever autofocus lens for Nikon DSLR full-frame cameras. The AF 14mm F2.8 lens has been developed using Samyang Optics’ globally renowned optical technology.
116.6° Ultra Wide-Angle with beautiful bokeh…
Inside the lens, there are 15 elements in 10 groups, including 2 aspherical elements, 4 highrefractive (HR) elements and 1 extra-low dispersion (ED) glass element to minimise distortion and chromatic aberrations, for crystal clear resolution. This lens offers a powerful 116.6 degrees wide angle-of-view. It also features 7 rounded aperture blades, which help to create beautiful bokeh (out-of focus backgrounds) in portraits, still-lifes and night-time cityscapes.
Faster, accurate and quieter Auto Focus performance…
The AF 14mm F2.8 F autofocus function is upgraded with Samyang’s advanced technology. The lens offers faster, more accurate and quieter autofocus performance than previous AF 14mm F2.8 lenses.
Capture vivid images anytime, anywhere…
This compact ultra wide-angle lens weighs only 484g (without lens cap and hood). The lens also features weather-sealing and a built-in AF/MF switch for increased usability. With a minimum focus distance of just 20cm, it is possible to capture more vivid close-up images of portraits, pets, food etc., anytime, anywhere.
Remotely flying a camera around in the sky, thanks to the affordability and sophistication of drones, is one of the newest and most exciting avenues for photography. You can buy a camera-equipped drone for well-under £100 and ones with decent photo quality start at £100-150. However, it’s not a free-for-all in the skies and concerns about safety are beginning to impact on even the hobbyist drone flyer.
New UK laws to keep drones safe and away from conventional aircraft
The UK government has announced new legal measures aimed at deterring drone operators from flying their aircraft irresponsibly. New laws will mean many hobbyist drone flyers will need to register their aircraft with the Civil Aviation Authority (CAA) and take an online safety test. The main aim is to protect passenger aircraft in airspace near to airports and aerodromes. Statistics suggest there have been nearly a 100 near-misses in the UK alone last year.
Altitude and distance limits
The first of the new regulations to come into force will happen on 30th July. By default, it will be illegal to fly a drone above 400ft (120m) or closer than 1km (0.6 miles) to an airport or aerodrome. Prior to that date the 400ft altitude limit has only been a recommended best-practice limit, as stipulated by the CAA and NATS (UK air traffic control) backed Drone Code. Many low cost drones are capable of exceeding this limit easily.
In the words of the government press release; “Drone users who flout the new height and airport boundary restrictions could be charged with recklessly or negligently acting in a manner likely to endanger an aircraft or any person in an aircraft. This could result in an unlimited fine, up to five years in prison, or both.”
Safe and responsible drone flying – the Drone Code summarised:
Make sure you are familiar with the manufacturer’s instructions for the operation safe operation of your drone
Keep below 120m altitude
Keep well away from airports and airfields
Keep your drone in visual sight at all times
Keep a minimum 50m distance from people and properties you don’t have control over
Keep 150m away from any built-up areas or crowds
Be aware that you are responsible for the safe and responsible flight of your drone. You could be liable for criminal prosecution if you fly dangerously or irresponsibly
Drones heavier than 250g
Later, from 30th November, operators of any drone with a take-off weight of 250g or more will have to register their drone with the CAA and pass an online safety test. Most drones fitted with cameras capable of good quality stills and video photography exceed the 250g threshold. If you don’t comply with the registration and test requirement you risk a £1,000 fine. It’s not yet clear if the online test will carry a fee or not. Currently, drones exceeding 20kg require licensing and must only be flown by people licensed to be qualified operators.
The new regulations are being brought into law through an amendment to the Air Navigation Order (2016). A quick perusal of social media sites specialising in drone discussion reveals a split in reaction to the news. Some drone flyers whose main interest is flying as high and as far as possible are, naturally, disgruntled. But other drone enthusiasts believe the regulations were inevitable and many already stick within the limits to be enforced anyway and hope that their hobby, or even profession as commercial drone operators, will be protected from bad publicity generated by irresponsible drone flying. However, whether the new regulations can be enforced effectively is greeted with widespread cynicism. While more sophisticated drones equipped with GPS positioning receivers usually record a log of their flightpath, containing valuable evidential information, other large and powerful drones don’t.
Airline pilots say measures don’t go far enough, literally
While the changes are designed to protect passengers and pilots flying big planes, the pilots trades union, the British Airlines Pilots Association (BALPA), has been critical of the 1km airport boundary, saying it should be more like 5km. Apparently, an airliner could quite legitimately be well under 400ft 1km from the runway.
Because the drone industry, both for recreational and commercial flying, is estimated to be worth over £40 billion by 2030, the government stresses that it does not intend to hinder the responsible operation of drones.
Taking your drone abroad to fly is now increasingly common but there are no internationally agreed drone flying rules. Nevertheless, the same 250g weight threshold and 120m altitude limit do seem to be mentioned frequently in local regulations around the world.
Fake or counterfeit memory cards that look like premium branded product, including convincing retail packaging, are a problem that everyone should take seriously.
What is a fake or counterfeit memory card?
Ciunterfeits will often look just like the real thing. Even slick retail packaging can be faked. Fake cards will often not have as much actual storage capacity as they claim and read/write speeds will be a lot slower. It may also be possible to spot visual clues as well. The counterfeiters can make cards that have much smaller usable capacity appear to contain a much higher capacity. These hacked cards work at first but once the memory has been used up, files already on the card start to be overwritten, causing file corruption.
About 18 months ago I saw a good deal on eBay for a 64GB SanDisk Extreme UHS-1 microSDXC memory card – ideal for my phone, I thought. It arrived and came, as advertised, in retail packaging. I was pleased. Much later, when downloaded music started playing back unreliably, and then photos and videos started to get corrupted, did the consequences of receiving a fake memory card come home to roost. By then the eBay seller was long gone and it was far too late to get any recompense.
Before I suspected my card of being a fake, I thought it was only faulty. I tried scanning it for errors on my PC. Errors were found and, according to Windows, were fixed. But the problems eventually returned. Next, I tried a ‘slow’ re-format of the card, as opposed to a ‘quick’ format option. A quick format only reinitialises the table of contents, not the actual data across the entire card space. By un-checking ‘quick format’ you will reset all sectors on the card. This method should, in theory, uncover any bad sectors. But the reformat seemed to work fine. Surprise, surprise, file corruption eventually returned.
Suspecting your card is a fake
By this time I did some more simple tests. Copying large files to and from the card showed that the read speed was, incredibly, only 3MB/second and the write speed was, perversely, faster, but still a lethargic 7MB/second. A 64GB SanDisk Extreme UHS-1 microSDXC card should allow data to be read at around 80MB/sec and written at 50MB/sec. It was beginning to dawn on me that this wasn’t a real SanDisk Extreme card, but a counterfeit. Later on I also spotted that one of the typefaces on the card itself did not match that of a genuine card.
Get the evidence for a refund or replacement
You can avoid an experience like this easily. All you need to do is test your brand new memory card as soon as you receive it. Don’t delay; the sooner you know the card is a fake, the better your chances are of getting recompense. Only buy via respected or protected sources; eBay and Amazon, for example, will help you get a refund or replacement even if the original seller does not cooperate. All you need is proof your card is fake. Here is how to do exactly that.
The h2test2w utility writes to every sector in the card’s memory map as well as verifying and speed testing. It is capable of overcoming false capacity hacking of the card’s specifications. After running the utility it was clear that my 64GB SanDisk Extreme card was a fake, with only 8GB capacity, despite appearing to Windows and my phone as a 64GB card.
I’d also recently bought a couple of other cards, one of which was another steal of a deal on an eBay auction; a Panasonic V90 U3 64GB SDXC card, which normally sells for £200. My £55 auction win needed urgent validation! Thankfully, it passed the test with flying colours. I already had one of these cards so tested that as well and the results were pretty much identical.
The testing process can take a while, depending on the speed of the card, but it’s a great way to make sure you’re getting what you paid for. It can also serve to identify a genuine product that is non-maliciously faulty. I will be testing all new card purchases from now on.
This year’s The Photography Show starts today at the rather cold and snowy Birmingham National Exhibition Centre (NEC).
I’m here at the show today to search out the show highlight, including interesting exhibits and show gear deals.
Here’s my first update from the show; a gallery of shots from WEX, Cameraworld and LCE, who are the main three camera retailers exhibiting this year:
Meanwhile, all the main camera marques are exhibiting. It has to be said the Nikon stand, although located in a prime position near the main entrance, seems smaller and less visible than it has been in the past. Canon has a massive stand at the opposite end of the hall, complete with cavernous presentation theatre. Olympus, Panasonic, Sony and Fujifilm occupy the centre of the hall with spaciously large stands. Pentax/Ricoh are off to one side with a rather more modest sized stand. Sigma again has a large and impressive stand to show off its wares. Tamron’s is more modest. A gallery of shots from the show aisles will follow later.
For more information about the exhibitors attending and the parallel events, including talks by great name photographers, check out The Photography Show official website.
Is Canon heralding a bid for dominance of the mirrorless system camera market?
If there is one thing that emerged from the recent CP+ photography trade show in Japan it was confirmation that mirrorless cameras will finally take over from DSLRs. Canon bosses are reportedly targeting domination of the mirrorless system camera sector after years of fairly innocuous involvement at the fringes. An interview by the DPReview mega site with Sony’s camera division General Manager, Kenji Tanaka, appeared to confirm Canon’s intentions and more.
Sony, Fujifilm, Olympus and Panasonic Lumix, currently own the mirrorless system camera market. Nikon and Canon have, instead, tinkered with mirrorless cameras, carefully avoiding unnecessary competition with their established domination of the DSLR sphere.
Tough times for all system cameras
However, system camera sales across the board, including mirrorless, but especially DSLRs, are facing tough competition from the ubiquity and improving quality and usability of cameras in smartphones. But it seems mirrorless is now recognised as the more profitable and sustainable avenue for the future of system cameras.
Sony’s Tanaka not only expects Canon to invest heavily in mirrorless, especially full frame, but Nikon, too. While they can technically claim to have been a reasonably early participant in the mirrorless revolution, Nikon went for a small 1 inch sensor format for its Nikon 1 system. Sales never really took off and there hasn’t been much in the way of new Nikon 1 releases for some time. Canon has been very conservative with its EOS-M mirrorless system, though its more recent models like the EOS-M5 and M50 show a rapid expansion in Canon’s ambitions, albeit still only in the consumer sector.
Professionals will be key
Despite the arrival of some increasingly impressive professional specification mirrorless cameras, DSLRs are still the mainstay of most high visibility press, sports and wildlife photographers. Nikon and Canon DSLR shooters value not only the excellence of their gear but also the extensive and vital professional support provided by the two big marques.
But there is no getting away from the facts. DSLRs and their lenses are relatively big, heavy, and now no longer as dominant in image quality and performance in other technical areas like autofocus and shooting speed. DSLRs are also mechanically more delicate and complicated to manufacture. A lot of specialist professionals have switched away from Nikon in order to lighten their camera bags.
Meanwhile, features like video, image stabilisation and new trick functionalities are giving mirrorless cameras key advantages and genuine appeal for professionals. Nikon and Canon are going to be duty-bound to provide professional grade mirrorless cameras for their legions of professional photographers. This will finally endow the mirrorless sector with the professional legitimacy it has sought to achieve for so long.
Panasonic Lumix invented the modern mirrorless phenomenon ten years ago when it launched the Micro Four Thirds system via the Lumix G1. It’s taken a long time, much longer than mirrorless fans predicted, but there are now clear signs that the dominance of the SLR era really is about to end.
