Manual Focusing with AF Camera Systems | Carl Zeiss

Manual Focusing with AF Camera Systems | Carl Zeiss | Photography Gear News | Scoop.it


Superb image quality in today’s world of photography is fostered by a whole host of different factors such as the high numbers of pixels in digital SLR cameras, large format sensors in full-frame 35mm format or traditional almost-medium format, intelligent image processing techniques and noise reduction algorithms. The results are also dependent on how the camera interacts with the lens, which is why high-grade optics have such a vital role to play in fulfilling photographers’ increasingly sophisticated demands with regard to image quality.

 

The weakest link

Achieving top-quality shots with high-resolution cameras means keeping all the parameters that have a direct or indirect impact on image quality within strict boundaries. The idea that “a chain is only as strong as its weakest link” has particular relevance for photography and image reproduction.

 

Precision focusing

One of the key links in the chain of successful image rendering is the precision with which the lens focuses on the main subject. Generally speaking, a photographic lens only provides optimum rendering at maximum image quality of a two-dimensional plain. This plain runs exactly in parallel to the film or sensor in the camera. Depending on the magnification and the selected aperture, a certain range both in front of and behind the point of optimum focus is also considered to be "adequately sharp". In this context, the magnification refers to the ratio between the image produced by the lens and the object being photographed. Thus, the focal length of the lens, the shooting distance and the size of the film or sensor are responsible for the so-called depth of field. The focusing region designated as the depth of field is the extent of the range in the object space of an imaging optical system. This region is rendered in acceptably sharp focus on the focal plane.....

Canon EOS 7D Mark II Review: Digital Photography Review

Canon EOS 7D Mark II Review: Digital Photography Review | Photography Gear News | Scoop.it

Canon's EOS 7D Mark II was a long time coming. It arrived in time for Photokina 2014, combining a pro-grade AF module with a 20MP APS-C CMOS sensor using Dual-Pixel AF. The 7D II also provides 10 fps continuous shooting, a 150,000-pixel RGB + IR metering sensor and 1080/60p video recording. It's as robust a feature set as you'll find in the APS-C class, and its autofocus specs are truly impressive. Read our full review and see how it performed in the studio and in the field.

Note that this review contains three 'lab report' pages in which we introduce the concept of 'ISO-Invariance' in connection to our comparison between the image quality of the EOS 7D II and some of its competitors. We will be revisiting this subject in greater depth in a future article.

Micro-Nikkor AF-S 105mm f/2.8 G IF-ED VR (FX) - Review / Test Report

Micro-Nikkor AF-S 105mm f/2.8 G IF-ED VR (FX) - Review / Test Report | Photography Gear News | Scoop.it
Stabilized macro lenses have become a fairly common thing nowadays, but when the Nikon AF-S 105 f/2.8 VR was announced in 2006, it was the first of its kind. The lens replaced a highly regarded, but somewhat aged design, featuring all the goodies a new lens needed to offer, including a silent-wave autofocus drive, Nano Crystal coating and of course its key feature, the optical stabilization system.
The addition of VR to a macro lens caused a few raised eyebrows back then, questioning the usefulness of this feature in "real" macro shots. However, there's of course a lot more you can do with a macro lens than 1:1 shots, and in most of these situations optical stabilization offers an advantage, either by allowing slower shutter speeds and/or by giving a stable viewfinder image for easier framing of the shot.

Being a little aged itself now, let's have a look at how the lens performs on our current FX test camera, the Nikon D3x.

Nikkor AF-S 58mm f/1.4 G (FX) - Review / Test Report

Nikkor AF-S 58mm f/1.4 G (FX) - Review / Test Report | Photography Gear News | Scoop.it
The wide- to short tele prime lens market is currently in a bit of a turmoil. Driven by Zeiss and also Sigma, the manufacturers are exploring extreme quality designs ... as well as corresponding price tags. In the standard prime lens segment, Zeiss started the game with the Otus 55mm f/1.4 followed by the Sigma 50mm f/1.4 HSM DG "Art". Obviously Nikon felt the heat and released the Nikkor AF-S 58mm f/1.4 G. At 1700 US$ this is clearly not for the faint-hearted although this is almost affordable by Zeiss Otus standards.
"58mm" may sound like an unusual choice but this is actually not a first for Nikon here. Back in the old days, they offered a Noct-Nikkor Ai-S 58mm f/1.2 - a legendary lens renowned for great performance at max. aperture. We'll see whether the current AF-S 58mm f/1.4 is capable of following this guidance.

HTC introduces the RE digital camera

HTC introduces the RE digital camera | Photography Gear News | Scoop.it
Smartphone maker HTC has introduced its first stand-alone camera in the shape of the HTC RE. With no viewfinder, screen or controls other than a shutter release button, the RE is designed to be used either as an independent still and video camera, or as a connected device controlled via a smartphone. Housing a 1/2.3-inch CMOS sensor that features 16 million pixels, the RE uses a fixed-focus f/2.8 lens that HTC says has a 146 degree angle of view – equivalent to a 6.5mm focal length on a full frame body.

Sigma 150-600mm Sport review - super-telephoto zoom!

Sigma 150-600mm Sport review - super-telephoto zoom! | Photography Gear News | Scoop.it

The Sigma 150-600mm f5-6.3 DG OS HSM Sport is a super-telephoto zoom lens, available in Canon, Nikon and Sigma mounts, and corrected for full-frame use. Announced in September 2014, it replaces the earlier 150-500mm f5-6.3, extending its reach while also offering higher performance and tougher build. It also now allows Sigma to compete on range with the existing Tamron 150-600mm f5-6.3.


Interestingly, Sigma is replacing the 150-500mm with not one, but two new lenses. Both share the same 150-600mm f5-6.3 specification, but have different levels of quality, construction and sealing. The higher-end Sport version reviewed here is fully weather-sealed, while the more affordable Contemporary version, yet to be released, employs a simpler optical construction and sealing at the mount to hit a lower price point. While the full specification and price of the Contemporary model were not known at the time of writing, the dual-offering remains a cunning approach by Sigma, allowing the cheaper version to compete with Tamron and the pricier one to go up against premium options from Canon and Nikon. Sigma appends the model names with an S for Sport or a C for Contemporary, so officially speaking I'm reviewing the 150-600mm f5-6.3 DG OS HSM | S.

Like the 150-500mm before it, the 150-600mm range is ideal for wildlife and sports photography, tight sunsets, or even distant street work. Despite Sigma's previous success with this range it's also one that's not been covered by Canon and Nikon, making it unique to third parties. And while the Sport version is a premium lens, Sigma's still managed to price it a little below the most recent Canon 100-400mm and Nikkor 80-400mm options, missing out on their slightly wider coverage, but crucially reaching 50% longer. Read on to find out if this is the best super-telephoto zoom for your DSLR or mirrorless camera!

Canon EF-S 24mm f/2.8 STM - Review / Test Report

Canon EF-S 24mm f/2.8 STM - Review / Test Report | Photography Gear News | Scoop.it
Back in 2012, Canon introduced the Canon EF 40mm f/2.8 STM - a full format pancake lens. Pancake lenses have a short barrel in an attempt to minimize the size of the overall setup. Because of their size, pancake lenses tend to have a rather moderate speed and, for obvious reasons, they are also limited to a rather shallow range of focal lengths. Now it seems as if the concept was successful enough to release another one - the Canon EF-S 24mm f/2.8 STM. As you may notice, this is not a full format lens but designed for APS-C DSLRs only. In this scope it actually resembles its full format counterpart because the field-of-view is equivalent to a "38mm" full format lens.

Nikon 20mm f/1.8G ED – Initial Impressions

Nikon 20mm f/1.8G ED – Initial Impressions | Photography Gear News | Scoop.it

Since Nasim has been photographing the beautiful golden aspens in Ouray County, Colorado with members of the Photography Life community for the last few days, I thought I would provide some early thoughts and samples of photos taken with the new Nikon AF-S 20mm f/1.8G ED. Once Nasim is back in town, he will post a much more detailed review of this lens. I would call this a “Nasim Light Lens Review,” but that would be giving myself too much credit!


Many have been very impressed with the Nikon’s f/1.8G series, which includes the 28mm, 35mm, 50mm and 85mm. Each represents a great value relative to their more expensive f/1.4 counterparts, and in some cases, as good if not better performance. And while the new 70-200mm f/4 VR lens is not one of the f/1.8G series, it represents the same style and value proposition.

I had previously owned the 28mm f/1.8G, which I loaned to Nasim for his detailed review. It was a fine lens, but I did not find the focal length to be very useful. It was not a wide angle lens and was just 7mm shy of my Sigma 35mm f/1.4. The only real advantage it had over the Sigma was weight. The Sigma is such an exceptional lens, however, so I eventually sold the 28mm f/1.8G. What I really wanted was an 18mm or 20mm f/1.8G. Nikon finally answered the call...

The ultimate photo shoot: on location in Iceland with the iPhone 6 and 6 Plus

The ultimate photo shoot: on location in Iceland with the iPhone 6 and 6 Plus | Photography Gear News | Scoop.it

As with any smartphone in 2014, there's no more important feature than the camera. It's what we use to take photos with our friends and families, how we remember what we ate and what our kids looked like way back when.


The camera has always been one of the iPhone's most impressive feature, and this year, Apple says it's gotten a huge upgrade. The iPhone 6 and 6 Plus feature new sensors, better optics, new technologies that aid in stabilization and HDR, even slower slo-mo video, and much more. They're meant to destroy your point-and-shoot, your camcorder, and maybe even your DSLR.


To see what the new devices can really do, travel photographer Austin Mann went to Iceland on a week-long photography adventure. He's been shooting in some incredible places, in incredibly difficult conditions; he's put both iPhone 6 and iPhone 6 Plus to their ultimate test.


Here are his photos, and his story. For lots more of both, check out his website.
