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). You can click on the images below to enlarge them.
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.
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.
It has only just been released and it has already been tested! I have just spend over a week testing the new professional reflex camera from the Nikon DX product line: the Nikon D7500.
More than 2000 photos later, here is all the information you will need to determine whether or not this reflex camera – which is situated between the D5600 and the D500 – is right for you!
Test of the Nikon D7500: presentation
The Nikon D7500 is an APS-C reflex camera with an impressive technical datasheet which completes the Nikon DX product lineup:
- 20 megapixel sensor without a low-pass filter from the Nikon D500,
- Expeed 5 processor,
- 8 images/second burst mode,
- integrated flash,
- 4K video in mp4 format.
You can consult the list of differences between the D500 and the D7500 here.
The Nikon D7500 is the answer for photographers who are in search of a DX camera with professional ergonomics and with the best currently available Nikon DX sensor within a compact and light-weight format. In other words, performance characteristics very similar to those of the D500 – if you don’t mind living without certain technical and ergonomic features – all for a lower price of around 700 euros (according to a comparison of publicly available prices).
As I do for every camera, I conducted this test of the Nikon D7500 under different shooting conditions in order to evaluate its general performance. In the text that follows, I will give you my opinion of this camera after having used it, in comparison to other models which I have recently tested – the D500 in particular.
Test of the Nikon D7500: ranking
With the introduction of the Nikon D7500, Nikon was able to reorganize its professional DX product line. Instead of offering only one professional model, as was previously the case with the D7000, D7100 and D7200, it is now possible to choose between two models:
- the Nikon D500,
- and the Nikon D7500.
Nikon D7500 vs Nikon D500
Both of these models use the same sensor, meaning that the image quality of both is the same. It is in terms of performance and ergonomics that these two cameras differ:
Full Frame: Nikon’s bold gamble
When Nikon announced D750, two things happened. First, some slowdown was noticed amongst buyers of D810, of which a quite significant number would have waited a little more to invest in a D750 and by the way saved 1000 dollars in price difference. I can understand them, it makes sense even if, a closer examination shows that Nikon D810 has some specificities that D750 does not have; we will get back to this. Then, and strangely enough, some have thought that the launch of D750 marked the end of Nikon D610. And that frankly, I do not buy for a second, I rather believe the opposite. I think that with the launch of D750, Nikon has firmly established its range of digital SLR (Single Lens Reflex), taking up the challenge of full frame. Personally, this range does holds up, up to four times better. Except for Nikon D750, I have used all cases of the Nikon full frame range during long work sessions. Just yesterday, I was working on pictures taken with Nikon D610 and I was captivated by the image quality, dynamism and sharpness. Last July, during an interview, I was asked what would be my advice to a young professional photographer wishing to start using the Nikon range and I answered without a moment’s pause, Nikon D610. My answer might be different today with the announcement of Nikon D750, but nonetheless, each Nikon case belonging to the full frame frame range has its own assets. It is impossible to contrast one with another and difficult to compare them. Each reflex has its target and its customers it will match. Following is a brief overview of the Nikon 24*26 range, but first a basic question. Why choose a Full Frame?
Why a full frame format DSLR?
Photographers from Argentina (mentioning no names) would look at you in a funny manner if you were to ask them that question. This is because, in olden days, you see, the film was not cut into pieces, a SLR (single lens reflex) camera was 24*36 and that was it. When the digital showed up, there were contingencies and technical requirements which made it more economical and less costly to manufacture sensors that are not full format. In the beginning, Nikon has delivered DX sensors with a conversion factor of 1.5. Canon, on its side, has made APS-C sensors on its amateurs range (conversion factor of 1.6) and even APS-H (conversion factor of 1.3) on some SLR of the Pro range (e.g. EOS 1D Mark IV). Some have seen in the non full frame sensor a major advantage. Indeed, an optical of 200mm behaved like a focal of 320mm, all this with the help of APS-C sensor alone. But what was interesting upstream proved more difficult in the other direction. It was not wise enough for a 16mm to become a 26mm. Full format also affects other parameters such as the depth of field, the quality of the image and its dynamics and leads to a more demanding range of optics.
With the announcement of the D7500 and Nikon’s intentions of retaining the D7200 in their product catalog, choosing a professional APS-C DX reflex camera has become more difficult. So, Nikon D7500 or Nikon D500, which one should you choose? Listed here are the main differences between these two devices as well as a comparison chart to help you make up your mind.
Nikon D7500 or Nikon D500: Which Nikon DX should you choose?
By announcing the Nikon D7500, Nikon was satisfying the demands of users interested in a professional device with an ergonomic design (see the test of the Nikon D500) as well as those users interested in a lighter, more compact device that is as capable as any other.
Late last month, Sony silently launched the latest full-frame mirrorless camera A7II. I can’t help but admire how well Sony kept this innovation confidential before its release. Sony is perhaps one of the few companies that could afford to launch a new model of a full-frame camera at a yearly rate. Actually, it’s no wonder that the A7 series has been selling so well. Their integral market performance since their release is surpassing Sony’s expectations. The latest A7II may have caused some confusion for those planning on purchasing one– Sony α7II and Sony α7, which model is better?
Before that, we all regarded the three models of A7, A7R, and A7S with different positioning as the three brothers of the full-frame SLR cameras in the Sony A7 series. However, the latest A7II is the brother with the closest kinship to A7. Even so, between these two brothers, which one should we choose? This is a question we need to ponder. Since the A7II was just launched, currently its single body price is $1698. The A7 has been marketed for more than a year and features a higher performance price ratio, but its current price on Amazon is only $1298. With that price difference of $400, we can almost buy another Sony A6000. So what justifies this gap of $400?
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.
The Samsung Galaxy S8 undoubtedly has one of the best cameras on the market this year, and with its improved camera, it is sure to follow the same path as the S7 Edge did when it became the best camera of its moment.
Last year, the iPhone 7 Plus showed us how its portrait mode turned its camera into one of the best ones of the moment. No other brand has this mode, except for Huawei and its dual camera, although the performance of Huawei’s phone is not as good as that of Apple’s device. Today we are testing the best two current phone cameras thanks to a comparison we found.
Samsung Galaxy S8 camera vs iPhone 7 Plus camera
We are going to show you a comparison between the latest Samsung Galaxy S8 and the iPhone 7 Plus dual camera, so we will have a lot to talk about. In this image, we can see that colors are richer and brighter with the S8 camera, while the iPhone 7 Plus has a better color reproduction. In terms of detail, Samsung’s device remarkable performance wins.
