When we apply this rule to photography we can immediately see one disadvantage of cameras with larger sensor sizes. Basically, it’s a formal way of saying that one thing P naturally implies Q. There is a principal of mathematics known as modus ponens which is used as a way of showing a certain thing to be true because it follows a logical progression. Lastly, just because a camera can shoot at ISO 25,600 doesn’t mean it’s the right one for you. It’s not a zero-sum game though, and there are many other practical considerations to think about. However, if you want the absolute best in terms of high ISO sensitivity, a modern full-frame camera is usually going to be your best bet. Granted the latter is a few years old and has since been bested by other full-frame cameras, but still, the point remains that today’s crop-sensor cameras are no slouch when it comes to shooting at high ISO values. The Fuji X-T1, a modern crop-sensor camera, is about equal to the full-frame Canon 5D Mark III in terms of high ISO performance. Most crop-sensor cameras today significantly outshine their forebears from just a few years ago when shooting at ISO 3200 or 6400. This analogy quickly breaks down when you consider the advances in modern technology. Shooting the same scene with a full-frame Nikon D750 yields much better results, with less overall noise and cleaner colors. So, when there’s not much light available, such as a situation where you may need to shoot at ISO 6,400 or 12,800, they do a better job of collecting the light. However, since the pixels on the D750 are bigger they are more sensitive to light. It’s kind of the same with cameras in that a model like the Nikon D5500 has a 24-megapixel image sensor which is the same as a full-frame Nikon D750. When the sun comes out and the birds start to sing, who will have collected more water? I’ll give you a hint, it’s not going to be you.Įven though you and your neighbor were both harvesting rainwater with 24 mega-buckets, hers were larger in size and therefore able to collect more water. Your neighbor, meanwhile, sees your plan and rushes to do the same thing but uses 24 ultra-mega-buckets that are about 30% larger than yours. To do so you set out 24 large buckets (so big you call them mega-buckets) next to each other and wait a few minutes for them to start filling up. So what’s all the fuss about? Understanding some of the practical differences between these two types of plates…er…cameras will help you know which type is best for you.įor example, pretend it’s raining and you want to collect some of the water that’s falling freely in your front yard. So what’s all the fuss about? Understanding some of the practical differences between these two types of plates…er…cameras will help you know which type is best for you. Both will get the job done, and both are great for different types of people. Shooting with a full-frame camera is like taking a normal size plate to the serving area, whereas using a crop sensor camera is like using a plate that is about 30% smaller. Think of it like going to an all-you-can-eat buffet with different sized plates. Using a smaller sensor has interesting effects on things like depth of field and apparent focal length of lenses, but it’s not a subjective measure of how good or bad a camera is. How the smaller sensor affects your images The most common size that the term crop-sensor refers to is known as APS-C, which is the same size as a piece of film from the mid-1990’s Advantix format (also called the Advanced Photo System or APS) invented by Kodak. A full-frame sensor is the same size as a piece of 35mm film which was, and still is, the most widely-used type of film in analog cameras. The term crop-sensor or full-frame refers solely to the size of the imaging sensor inside a camera. Even mobile phones, which are basically super-duper-ultra-crop sensor cameras, can take breathtaking award-winning shots that grace not only social media feeds but billboards, walls, and pages of magazines across the world. Moreover, all types of cameras are capable of taking great photos. All of them are different, and each format has its strengths and weaknesses (yes, even full-frame cameras have weaknesses!) and each is ideally suited to different types of photography. Different, not betterīefore I get too deep into this article I want to make one thing clear neither crop, nor full-frame, nor medium format, nor micro-four-thirds are any better than the others. This duck is rushing to get the latest full-frame camera he read about on the internet.
