Today, Nikon has announced a new DX zoom lens for beginner photographers. Covering a vast focal length range of 18-300mm, it’s not the first Nikkor with such parameters – the similar 18-300mm f/3.5-5.6 VR lens has already been announced a while ago, not to mention all the third-party competition from Tamron and Sigma. However, the new lens is designed not to just deliver a very wide zoom range, but deliver it in a smaller, lighter package. To put it into perspective, the new lens weighs a whopping 280g less than the bigger version. Quite an achievement and will surely be tempting for those few who need such a lens, but it came at a bit of a price both literally and figuratively. And that raises a question – who is actually going to need such a lens?
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.
