The J1 is a compact mirrorless camera that offers excellent optics and autofocus performance, featuring a Nikon CX size sensor. It's ultra portable size and weight make it a great camera to always have with you for every opportunity.
The Nikon D600 is a full frame FX DSLR. It features a 24.3MP sensor. It is the most affordable full frame DSLR produced by Nikon, but more importantly it is the lightest FX camera available. Constructed with a magnesium body structure, it is more tough yet portable.
The Nikon D800 takes digital photography to a whole nother level. With a 36MP sensor, dual memory card slot, new autofocus system, and the option of no anti-aliasing filter. This review covers the camera extensively.
The Nikon D4 is the new Flagship DSLR from Nikon. It features the most advanced autofocus system, greater control, and improved metering.
Under the hood is a 16.2MP sensor with native ISO from 100-12,800.
The Nikon 85mm f/1.4D is a classic portrait lens. It can be used for almost everything, including weddings, photojournalism, weddings, and events. Known for its bokeh, it can be found in almost any professional's bag.
The new Nikon 85mm f/1.8G is an active portrait lens. Perfect for weddings or events. It's 7 bladed diaphragm may produce decent bokeh. This is an ongoing review. The lens is expected to arrive early Feb.
This older 24-85mm 3.5-4.5G AF-S is an excellent affordable FX zoom. Although it does not feature VR, it is small, light weight, and easy to bring along anywhere. Its performance is more than adequate for most uses.
The Nikon 70-300mm VR G is a great lens for both DX and FX. Built well with great optics, it is a popular lens. Its VR works well. Read why this lens should be considered over many alternatives in this focal range.
Sharpness is the ability for a lens to resolve fine elements. It is typically measured in terms of black and white, line pairs per millimeter. Simply put, the finer the line pairs a lens can resolve, the sharper the lens.
Keep in mind that sharpness is only one characteristic of a lens and should not be the only thing considered when purchasing. Most of the time, sharpness is over emphasized. Nearly all Nikon lenses are sharp. The lenses reviewed here are all capable of achieving high levels of sharpness.
Each lens score was determined using a pair wise comparison, and on my experience, test and evaluation.
Bokeh is the quality of blur a lens can produce. It originates from a Japanese word that means confusion. Sometimes in photography, shallow depths of fields are desired, backgrounds are commonly blurred out to eliminate distractions from the subject. Bokeh is the quality of the blur a lens can render. The important word here is quality, not the amount a lens can blur.
Bokeh is a subjective matter. Typically a more Gaussian blur is preferred, where elements of the blur fade and transition smoothly. Contrary, an example of undesirable bokeh would be patternish blur with hard edges. This type of blur usually takes away from the subject.
The build quality describes a lens’ durability, reliability, and overall handling. Some of Nikon lenses are made in Japan, while others are made elsewhere in places like China and Thailand. Although Nikon’s level of quality is always a leader in the industry, regardless of where a lens is built, some lenses are built better than others.
Additionally, features such as vibration reduction and manual focus override (M/A) encompass the build score as well because the overall usability is enhanced. Newer lenses that provide these features along with robust designs usually score high in this category.
When assessing value, price should be computed as an independent variable. Value encompasses all capabilities and performance of a lens and compares it to Nikon’s asking price. As of October 16, 2011, Nikon introduced a fixed point of sale pricing policy. Basically, online retailers cannot discount their lenses. Nikon will not ship if they see any discounting. This excludes open box items and of course the used market.
The value score for each lens is determined using a pair wise comparison of all the features and capabilities against each lens, and then divided by the price. This may be somewhat misleading and you should read the pricing section in my lens review before purchasing.
MEGA PIXEL COUNT
Most manufactures signify camera quality based on mega pixels. Although this is a method to draw consumer’s interests, mega pixels are not a good way to measure a camera’s overall optical quality. However, when strictly discussing high end DSLRs, mega pixels a more important factor. Nikon’s DSLR vary in megapixel and sensor size.
The number of mega pixels is commonly a tradeoff to the amount of noise tolerated for a given senor. The greater the mega pixel count, the more noise becomes limiting. Currently, Nikon’s DX sensors, at 16MP and greater, are pushing the limits, not just on noise, but on the ability for a lens to resolve each pixel. The larger FX sensors provide greater possibilities for growth.
ISO (SENSOR NOISE)
ISO is the level of sensitivity a camera’s sensor is to light. It is specified as a number based on the old film speeds. Although camera manufacturers continually push the levels of sensitivity with each new release, true ISO can be measured and defined for each model.
True ISO can be measured by analyzing the noise levels based on a signal to noise ratio (SNR). As ISO (more sensitivity to light) increases, SNR and dynamic range is reduced. By analyzing the RAW performance of a sensor at a specific SNR and dynamic range, ISO can be measured unbiased regardless of the stated specifications.
The ISO scores here reflect the camera’s raw sensor unbiased performance based on my testing and evaluation.
The scoring for a camera’s build quality is based on my experience using the camera, how it handles, its features, and its capabilities. Depending on the user base, Nikon produces a variety of cameras with different qualities of construction and features. The professional cameras are built to the highest level of durability, while the consumer cameras are built “good enough”. The nice part about the consumer cameras is weight and size is much less than the professional cameras, which make them more portable and inviting to bring along.
When considering the scores for build quality, the user base is taken into account. So the more inexpensive consumer models are not unjustly scored less.
Assessing value is difficult when it comes to cameras. Photographers needs and market timing play a critical role in how a camera is valued. For example the D3X is overpriced. But this is possible because of market timing. The D800 provides a much better value and exceeds the performance of the D3X. But the D800 was not available for 3 years that the D3X was.
The value of a camera is measured on its performance, features and capability, while cost is treated as an independent variable. Value is independent of the class of camera, from pro to consumer level. The scoring for value encompasses all features, performance, and quality then divides it by cost.
