If you are a Nikon shooter, you might have found the announcement of the 70-300mm f/4.5-5.6E VR AF-P puzzling. While it looks great on paper, the lens seems to be ahead of its time, since the only cameras the lens is fully compatible with are the recent DX cameras. What is the point of announcing a full-frame lens, if it is limited to only a few DX cameras and practically no FX cameras? To me, it shows that Nikon is getting ready to announce something really big, something many of us Nikon shooters have been waiting for – a full-frame mirrorless camera. As I was looking at the details of the new 70-300mm VR AF-P, I realized that this lens would be an ideal candidate for a mirrorless camera. It is small, sharp and lightweight, which is exactly what a lightweight and compact Nikon mirrorless system needs. On top of all this, Nikon’s president has already hinted at an upcoming mirrorless release (link in Japanese, use Google Translate), although nothing was said about the format / sensor size. While this is my personal speculation, the release of the full-frame 70-300mm f/4.5-5.6E VR AF-P to me is an indication of a full-frame mirrorless coming to the market.
There have been some interesting discussions about the pros and cons of various sensor sizes and how they impact angle of view, lens focal length and the depth-of-field that results. For example, some photographers bemoan the fact that it is difficult to achieve a shallow depth of field at a particular equivalent-field-of-view with a CX sensor using 1 Nikon lenses, while others find it useful to be able to get deeper depth-of-field at more open aperture settings such as f/1.8 and f/2. Some D800 shooters are concerned about diffraction setting in above f/8 when trying to achieve deep depth-of-field with a high pixel density 36mp FX sensor, as are many photographers who use high pixel density sensor DX bodies.
Whether you’re an amateur or professional shooter the choice of which camera brand and format to buy can be daunting. Often after you’ve shot with it for a while another round of soul-searching can happen as you better understand the strengths and limitations of your gear, and consider where your photography and/or videography is going to take you. I suppose we all go on our own ‘gear journey’…this is mine.
Because the glass elements in a camera lens are round, lenses project a circular image onto a camera’s sensor plane. This projected image circle must be large enough to cover the rectangular sensor, like so:
It seems like the debate of DX vs FX for wildlife and sports photography is a never ending one. DX shooters argue that they get more reach, stating that DX is like a “built-in 1.5x teleconverter”, or that DX setups are lighter due to smaller lenses and less expensive, or that DX chops off the corners of lenses, thus reducing vignetting and other optical issues. On the opposite side of the fence, FX shooters argue that they get better image quality at pixel level, better viewfinder, less diffraction issues, better AF performance in low-light, etc. Seems like we have two camps, each defending their own side for various reasons. Having spent a number of years shooting both DX and FX starting from the first generation Nikon FX cameras and every single DX camera manufactured by Nikon to date, and having talked to a number of other photographers that shoot for a living, I came to a conclusion that there are some myths surrounding the DX format that need to be debunked. In this article, I will provide my personal insight to this topic and explain why I believe that FX is always better for photographing sports and wildlife. This article evolved as a result of recent discussions of the subject with some of our readers.
In this article, I will show feature differences between the new full-frame Nikon D600 (FX) and the older cropped sensor Nikon D7000 (DX). I have received a number of requests from our readers asking me to provide this comparison, since many photographers are considering to move to the Nikon D600 from their D7000 cameras. Please keep in mind that this Nikon D600 vs D7000 comparison is purely based on specifications. A detailed comparison with image samples and ISO comparisons is provided in the Nikon D600 Review.
Although I called this article Why DX has no future, I believe it applies to all cropped sensor DSLR cameras, not just Nikon. Earlier in 2012, I wrote an article called “The Future of Digital Cameras“, where I shared my thoughts on what I think will happen with DSLR, Mirrorless and other camera technologies within the next few years. One of the main points of the article, was my opinion on DSLRs and why I think they are here to stay for a long time. I did not clarify what I meant by DSLRs, because the DSLR technology defines how the camera works, not what type of sensor or features it has.
Some of the most frequently asked questions from our readers are around DX and FX format sensors. What is DX and FX? What are their differences? Which one is better and why? If you have similar questions and want to get a clear understanding about these formats and their differences, along with seeing actual image samples from both, this article is for you.
