Lastly, lower resolution cameras are more forgiving on focusing errors and lens resolution – slight focus errors will rarely be noticed in images and if a lens is not capable of resolving a lot of detail, you will not see it in images anyway. Smaller files also put less strain on the camera buffer, allowing more images to be captured continuously at high frame rates. Fourth, smaller files also make it possible for cameras to push higher frame rates, allowing them to be used for such needs as sports and wildlife photography, where fast frame needs are often needed to capture the right moment.
Third, lower resolution images typically do not need to be resized / down-sampled – they look pretty clean “as is”, so if you need to quickly process and provide them to someone, you can do it with ease. Second, smaller files also reduce the overall need for storage – you can use smaller capacity memory cards and smaller backup storage (whether local or online). You can continue to rely on older computer hardware and even some of the lightweight “ultrabooks” can handle such files with ease. First, it results in smaller files, which are easier and faster to post-process. Lower resolution comes with a few advantages, as well as disadvantages.
Advantages and Disadvantages of Low Resolution Cameras Why would one choose 12 MP and why would one choose 50 MP? What are some of the concerns and issues one needs to understand and take into account? Let’s analyze these in more detail. When looking at cameras today, we see a number of different options, with camera’s ranging from 12 megapixels to a whopping 50. Hence, such terms are relative to the highest resolution sensor available today. Just a few years back, what I refer to as “low” in this article was considered state of the art. Please keep in mind that the term “low resolution” refers to the least resolution we see in modern full-frame cameras. In this article, I want to address these concerns and talk about pros and cons of low versus high resolution cameras. They want to understand the advantages and disadvantages that such high resolution cameras bring and what changes they can anticipate to their workflows. With the release of high-megapixel cameras such as the Canon 5DS / 5DS R and the Sony A7R II, more and more photographers are getting interested in these tools. This article is meant to be an extension to the Camera Resolution Explained article that I published back in February of 2015.
