It’s brand new, it’s beautiful, and above all, it has arrived at our photo lab: the Nikon D850. And what a joy it is! It’s enough to make us happy to have returned from holidays. And we are full of energy and motivation as well as curiosity: so, how does its 45.7 megapixel BSI CMOS 45,7 sensor stack up against the current kings of high definition?
It was not difficult to make a selection of cameras able to compete with the Nikon D850 as its only serious competitors are: its predecessor – the D810, the Sony Alpha 7R II and the Canon EOS 5Ds R. In order to avoid favoritism, for the purposes of this test, all of these cameras will be mounted with a Sigma Art 35 mm f/1.4 DG HSM lens (one with a Nikon F mount and one with a Canon EF mount). The two questions we will be asking are: what can Imatest tell us about the resolving power of the Nikon D850? And, how does the camera behave at high ISO sensitivity values?
Imatest: a well-designed 45.7 megapixel BSI CMOS sensor
The Imatest software, in association with SFRplus chart, is able to measure the resolving power of a given lens relative to a given sensor. In other words, while using the same lens, this test will determine a camera’s ability to distinguish very fine details in three distinct zones: the center, periphery, and edges of the frame. The graphs it produces are very easy to read: the higher the curves, the better (as far as resolving power is concerned), and the closer the three curves are to each other, the better (in terms of the lens’s homogeneity at a given aperture opening).

Compared to the D810, the D850 is more precise at wider aperture, despite being equivalent at f/8. However, the D850’s increased definition makes it more susceptible to diffraction effects. If you commonly operate at f/11 and beyond, the D810 would probably be better suited to your needs.
Today, Canon announced the release of a new entry-level hybrid camera which will become the newest member of its EOS M product line: the Canon M100. Equipped with a 24.2 megapixel APS-C sensor, the EOS M100 seduces by its compactness and cuteness in addition to incorporating much technology which was developed for higher-end mirrorless cameras.
It measures 10.82 x 6.71 x 3.51 cm and weighs in at 302 g (without a lens). It is the smallest and most lightweight of all of Canon’s hybrids. In fact, this camera more closely resembles a conventional compact camera than a hybrid.
The T6s is an upgraded product of the T5i. Canon has released a total of two replacement products for the T5i, which are the more advanced T6s and more entry level T6i. Unlike the T5i, which almost didn’t upgrade the T4i at all, Canon has taken a lot of care in the upgrade of the T6s. The T6s is the best entry-level SLR camera of the Canon line, if not the best of the SLR camera market, because it has promoted the manipulation of the entry-level SLR camera to a new level.
The T6i and the T6s can be considered as two different models of the same product. While the T6i follows the model style of the classic Canon XX0D series in manipulation, the T6s takes the 70D as an example, as it is not only equipped with a top LCD display but also has an installed Quick Canon Control dial, forming the classic double-command dial control style of Canon.
The latest product in the long chain of entry level Canon DSLRs are the Canon EOS Rebel T7i and EOS 77d. The origin of the Canon DSLRs can be traced back to the original EOS Digital Rebel that was introduced sometime in 2003.
From then till date, all the updates and iterations following it have all been generally accepted as a market choice by both experienced and new users. The latest EOS Rebel T6i/T6s from Canon has proven to be a market best choice entry-level DSLRs. It comes with features that make it suitable for new users, while its polished handling makes its usability easy.
The T7i and the 77D can be considered as two different models of the same product. While the T7i follows the model style of the classic Canon XX0D series in manipulation, the 77D takes 80D as an example, as it is not only equipped with a top LCD display but also has an installed Quick Canon Control dial, forming the classic double-command dial control style of Canon.
Knowing how to choose the material that best suits your needs when it comes to taking pictures is essential. Everyone knows that in photography nothing is cheap, so before buying anything I recommend that you think about whether it’s really something that you need.
Lenses are the most expensive things in photography, sometimes costing even more than the camera itself. That’s why it’s worth being well informed and reading many of the analyses and reviews that can be found on the internet.
While the essential ingredient of taking excellent photographs is yourself, having a good team of lenses will make things a lot easier.
Putting together a good team that accompanies you photo by photo as you travel your way into the world of digital photography isn’t as simple as it seems since there are hundreds of models, brands and technical aspects to consider, not to mention your budget.
