12-bit image files can store up to 68 billion different shades of color. 14-bit image files store up to 4 trillion shades. That’s an enormous difference, so shouldn’t we always choose 14-bit when shooting RAW? Here’s a landscape I snapped, then found out later I had shot it in 12-bit RAW. Better toss this one out, right?
A few months ago we wrote an extensive article on sensor crop factors and equivalence. In that post we covered several topics: the history of the cropped-sensor formats, brightness of the scene, perspective, depth of field, noise and diffraction. In today’s post I want to focus on (if you’ll excuse the pun) and expand on two of these topics:
If you are wondering about how images look from the newly announced Canon 5DS and 5DS R DSLR cameras, below you will find the official image samples from Canon USA for both cameras. Let’s take a look at the 5DS images first (apologies for wrong orientation on vertical images – our system could not properly handle orientation on such large files):
The choice of the first camera system is an exciting one. Why would it not be? You get to pick the first camera to buy, the first lens, and you spend so much time reading reviews, forums and asking friends for advice. I know I did – some eight years ago, I was admiring such cameras as the Canon 30D and 40D, and was seriously eyeing the 400D which was then within the budget of a teenager me. Nikon D200 looked out of this world and the then-announced D300 was a camera of dreams. All of these models, now obsolete from a technological standpoint (much like the D700 I now own and love), were as desirable as any current equipment you can think of. Maybe even more so, since the refresh cycle was longer and digital photography in general not as widespread as it is today.
Yes, the choice of the first camera and lens is a very exciting one. But, inevitably and at some point, a different question arises for just about all of us, and one much less pleasant – should you stick with your first decision or is the grass truly greener somewhere else?
Along with the exciting Nikkor 300mm f/4E PF ED VR, Nikon also announced a boring entry-level camera. After skipping the D5400 for no reason (Nikon marketing at its best), the D5500 was revealed at the CES with very similar specs as the D5300, except it gains a touchscreen and drops the GPS module. Same resolution, same processor, same fps, WiFi, same menu and features for the most part, except for slightly different design that resulted in a smaller and lighter camera. It seems like Nikon has no clue what else to add to the D5x00 line to make it more interesting and this release is one of those “announce to announce” series, yet another camera to add to the camera pollution just to keep the line fresh. Instead of doing something innovative (mirrorless design, EVF, focus peaking, electronic shutter, etc), Nikon adds a pointless touchscreen feature and gets rid of the far more important GPS component. With all this, Nikon increases the price of the D5500 by $100, pushing it towards $900 MSRP.
The subject of sensor crop factors and equivalence has become rather controversial between photographers, sparking heated debates on photography sites and forums. So much has been posted on this topic, that it almost feels redundant to write about it again. Sadly, with all the great and not-so-great information out there on equivalence, many photographers are only left more puzzled and confused. Thanks to so many different formats available today, including 1″/CX, Micro Four Thirds, APS-C, 35mm/Full Frame, Medium Format (in different sizes), photographers are comparing these systems by calculating their equivalent focal lengths, apertures, depth of field, camera to subject distances, hyperfocal distances and other technical jargon, to prove the inferiority or the superiority of one system over another. In this article, I want to bring up some of these points and express my subjective opinion on the matter. Recognizing that this topic is one of the never-ending debates with strong arguments from all sides, I do realize that some of our readers may disagree with my statements and arguments. So if you do disagree with what I say, please provide your opinion in a civilized manner in the comments section below.
Exactly after two years since the Nikon D4 announcement, Nikon made the D4s public at the 2014 Consumer Electronics Show (CES) on January 6, 2014. Although the camera was not ready for a full announcement, Nikon wanted to have something to show at the CES, so it only hinted about the development of the camera and its intentions to preview it. The camera was officially announced at the end of February and the first units started to ship shortly after in March. The Nikon D4s is a modest upgrade over the D4, with very slight ergonomic changes, expanded ISO range, faster image processor, faster wired / Ethernet speed, improved battery capacity and a bunch of new firmware options. As an incremental update, the Nikon D4s basically solidified the already superb D4 and made it even better.
It has been close to three years since Nikon announced the D4 and our readers might be wondering why I am only now reviewing the camera, especially given the fact that it has already been replaced by the Nikon D4s. While working on the D4s review, I thought that it would be a good idea to revisit the older D4 – better late than never! Since the camera came out, I have used it on several occasions for both personal and business needs, and a number of our team members have owned or still own the D4. Hence, the information and images that I gathered for this review represent a collective effort between our team at Photography Life.
Right before the big Photokina show in Germany, Nikon introduced another full frame DSLR in 2014, the Nikon D750. Packing the newest and the most advanced 51-point Multi-CAM 3500 FX II autofocus system, a 24 MP sensor, 6.5 frames per second continuous shooting speed, built-in WiFi and a very lightweight and weather-sealed construction, the Nikon D750 sits between the entry-level D610 and the high-megapixel D810 lines. And with its price point of $2,299 MSRP, the D750 is an attractive choice not only for hobbyists and enthusiasts who want to move up from a DX or an older FX camera, but also for working professionals, who have been leaning away from higher resolution or more expensive cameras like D810 or D4S. Although the Nikon D750 did not replace the older D700 in terms of body build, ergonomics and features, it has a lot more resolution, much faster processor, significantly faster and superior autofocus system, a tilting LCD screen and impressive video capabilities. Thanks to these changes and improvements, the D750 hits the sweet spot in a number of areas and has the potential of becoming the most popular full-frame camera in Nikon’s current DSLR line-up.
Instead of creating separate articles that show buffer capacity of every newly announced Nikon DSLR, we decided to gather and compile all the available information into a single location. The below table outlines many of the current and discontinued Nikon DSLR models, along with such information as sensor resolution, continuous shooting speed (fps) and RAW / JPEG buffer capacities. While we have included most of the RAW buffer information, we decided not to bother with smaller JPEG sizes, since most cameras presented below can accommodate 100 or more of smaller JPEG images in their buffers.
