Along with the 16-35mm f/4L IS USM lens, Canon has also introduced a budget wide-angle lens for its EF-S mount, the Canon 10-18mm f/4.5-5.6 IS STM. At a very compact size, image stabilization and just 240 grams of weight, the Canon 10-18mm will be an interesting choice for Canon’s APS-C line of cameras like 7D, 70D and Digital Rebel series. With an equivalent field of view of 16–28.8mm relative to full-frame, the lens will offer great ultra wide angle coverage. And with its MSRP price of just $299, it will be a great choice for beginners and enthusiasts interested in landscape, travel, architecture and everyday photography.
I am finally back in Denver after a three week-long trip to the UK and I am trying to catch up with all the news and announcements that we’ve missed. The first news items are related to Canon lens announcements from last week. Canon announced the EF 16-35mm f/4L IS USM image-stabilized full-frame lens for enthusiasts and professionals who want something cheaper than the EF 16-35mm f/2.8L II USM. Usually, f/4 lenses are lighter and smaller than their f/2.8 counterparts. However, the difference between the 16-35mm f/4L and 16-35mm f/2.8L is not as big – the former is just a tad thinner and weighs 20 grams lighter in comparison. The three biggest differences are obviously the smaller maximum aperture of f/4, $500 price difference and image stabilization. With a very similar optical design featuring the same number of elements and groups, 2 Ultra-low Dispersion (UD) and 3 Aspherical elements, the 16-35mm f/4L IS seems to challenge its big brother in a number of ways, even in optical performance.
For the past 8 months or so I have been shooting a lot of static and perched birds with a Nikon 1 V2, FT-1 adapter, my Nikkor 70-200 f/4 VR lens and TC-17E II teleconverter. This set-up gives me an equivalent field-of-view of 918mm @ a rather slow f/6.7. Even though the teleconverter does cause some loss of sharpness I’ve been happy with the results as you can see from the sample below.
While successful for perched birds, this set-up has been a different story for birds in flight. I’ve found that the auto focusing hunts a great deal at f/6.7 when trying to capture birds in flight, and the EFoV of 918mm makes it extremely difficult to keep a flying bird in the frame long enough to acquire focus. My skill set is such that other than getting the odd image of a cormorant flying in the distance at a 90-degree angle to me, I was unsuccessful in getting very many usable shots.
Along with the 400mm f/2.8E VR lens, Nikon has also announced the TC-14E III 1.4x teleconverter. The older TC-14E II version has been out since 2001 and Nikon finally decided to update it, most likely to match the performance of the new generation super telephoto lenses like the new Nikon 400mm f/2.8E VR and Nikon 800mm f/5.6E VR. The now previous-generation TC-14E II has always been praised by our team at Photography Life, thanks to its superb performance and very little performance degradation that is almost unnoticeable to the eye when using with most super telephoto lenses (see our article on how teleconverters impact image quality). In fact, my copy of the TC-14E II stays glued to my wildlife travel companion, the Nikkor 300mm f/4D AF-S (see my in-depth review) and I only detach it when I need to use the teleconverter with the 70-200mm f/2.8G VR, 200-400mm f/4G VR or other telephoto lenses.
Nikon has announced a new Nikkor 400mm f/2.8E FL ED VR lens which will be loved by wildlife and sports photographers. As you know from Nasim’s review of the previous version of the Nikkor 400mm f/2.8G lens, this is one sharp lens but weight was a big drawback. Nikon has taken action to reduce the weight by almost 2 pounds and is now actually 3 ounces lighter than the 500mm f/4G, making it hand-holdable for many of us! Some of the weight savings is from using 2 Flourite lens elements. The new 400mm f/2.8E is also lighter than the legendary Canon 400mm f/2.8L IS II.
In addition to saving weight, the minimum focusing distance of the new lens is approximately 12 inches less than the old version. There are 16 lens elements in 12 groups in the new lens, compared to 14 elements in 11 groups in the old lens. The front element diameter of the lens remains the same while the overall length of the lens is slightly shorter by 10 mm. Speaking of the front element, it is the first Nikkor lens to receive the fluorine coating, which Nikon claims will “effectively repel dust, water droplets, grease or dirt, ensuring easy removal even when they adhere to the lens surface“. This new fluorine coating will also be used in the new AF-S teleconverter TC-14E III which was also just announced.
For a while now, Sony’s biggest attention-grabbers in the camera industry were the mirrorless full-frame siblings, A7, A7r and the most recent, low-light and video focused A7s. Even so, to think that they’ve forgotten their DSLR system (although current Alpha cameras, such as the A99, technically are not really DSLR cameras) would be incorrect. Japanese electronics giant has enough resources and will to grow its customer base to provide deserved attention to all markets, which means those who still prefer the ergonomics of a full-sized camera can count on Sony not to leave them stranded. Today, Sony has announced what is to be the replacement of the venerable Sony A77, an SLT (Single Lens Translucent) camera we praised so highly in our review. So, what does this new camera, dubbed SLT-A77 II, improve over its predecessor?
There have been some interesting discussions about the pros and cons of various sensor sizes and how they impact angle of view, lens focal length and the depth-of-field that results. For example, some photographers bemoan the fact that it is difficult to achieve a shallow depth of field at a particular equivalent-field-of-view with a CX sensor using 1 Nikon lenses, while others find it useful to be able to get deeper depth-of-field at more open aperture settings such as f/1.8 and f/2. Some D800 shooters are concerned about diffraction setting in above f/8 when trying to achieve deep depth-of-field with a high pixel density 36mp FX sensor, as are many photographers who use high pixel density sensor DX bodies.
At the end of the day there is no such thing as a perfect camera body or format that will suit everyone’s needs. The camera body and sensor format you choose, along with your choice of lenses,comes down to the creative requirements that you have as a photographer based on the work you do.
Having been testing lenses extensively for the past few years, I have seen all kinds of optical defects on even the most expensive / exotic lenses that cost thousands of dollars. One of the most common issues I have seen so far is lens de-centering, where a single optical element or a group of elements are not properly aligned with others, resulting in uneven performance across the frame. Some lenses have very slight de-centering, which only software like Imatest can reveal, while others have very noticeable de-centering (particularly lower-end zoom lenses), where a portion of the frame would always appear less sharp in images. Then there are other optical issues that also impact the overall contrast and sharpness of lens. And testing lenses with all kinds of optical issues can often be a challenging task.
I have just added another section to the Camera Comparisons page of the Olympus OM-D E-M1 review, where I provided RAW performance comparisons between the OM-D E-M1 and the Fuji X-T1. Some of our readers requested this comparison, so here it is for those that just want to see this particular section of the review. Although the X-T1 has a similar resolution of 16.3 MP, it is physically larger in size (APS-C vs Micro Four Thirds) and hence has larger pixels than the OM-D E-M1. Let’s take a look at ISO 200 (Left: Olympus OM-D E-M1, Right: Fuji X-T1):
Grimsby Ontario is on the raptor migration route and every year the town holds an indoor “RaptorFest” event at the local hockey arena during which various presentations of live birds, and educational initiatives are conducted. A fast, mid-range telephoto like the Nikkor 200mm f/2G VR would be the perfect lens to photograph birds during this indoor event. Like most people, I don’t have the $6,000 or so it would take to own the 200mm Nikkor…but I thought I might have a reasonable solution in my camera bag.
