I had a bokah discussion and experiment with a photographer friend. So, equipment wise, my priority is good glass! However, my 6 lenses were purchased new for a total of 8 grand!. My two bodies were low shutter-count, mint, used equipment totaling a grand. I have a slow and considered approach to my craft and this counts for much more than pixel count or sensor size!. You can enlarge a 5mp aps-c image to billboard size and never know. And please don't tell me about FF and billboards!. Now, take a 10"x8" negative and place an aps-c and FF sensor next to it and you will see that the difference in size between aps-c and FF is negligible!. If you were to ask Ansel Adams, he would say that full-frame IS a 10"x8" plate camera!. I can enlarge my D2xs images up to 40"x30"!. My clients do not question how many pixels my camera has, or what size the sensor is. Unless of course you do that small segment enlargement!. Resolution has increased to the point that it becomes almost impossible for the human eye to tell the difference between an image taken on a 20mp camera and one that has 3 times as many. The fact is, the human eye can only discern so much information. Have you noticed that whenever aps-c and FF images are compared, a small segment in each is massively enlarged just so you can see the difference!. I am a professional wedding photographer and my two bodies are a Nikon D500 and D2xs. Of course once display equipment becomes 8k or greater, most of us will need cameras with higher pixel counts, unless the display equipments extrapolation is excellent. It might even be argued that a crop from a 24mp sensor could give a better result if it's easier for the display equipment to interpolate. You could then crop as you would on a 'full frame' sensor, if both cameras had 24mp sensors you'd have the same picture displayed. To achieve the same field of view on a cropped sensor use a wider lens. With regard to field of view differences, the article makes a good point of the wider field of view being useful in capturing moving objects. So a good modern camera is more than capable. I won't even start on potential print sizes at 300dpi. So micro 4/3 16mp sensor is overkill by either 8x or 2x, a 24mp sensor is 12x or 3x overkill. Provided the image is captured well on the sensor everything currently gets cropped to view it.Ī HD screen 1920 x 1080 pixels is around 2mp, a 4k screen is around 8mp. It's not so much anything to do with sensor size 'crop or full frame', as to do with usable pixel count (viewable pixels). The Canon EOS 5D has a surface area of 864 square millimeters, resulting in a pixel density of 34,800 pixels per square millimeter. The pixel density is 59,500 pixels per square millimeter. For the Canon EOS 7D Mark II, the surface area is 336 square millimeters. I am going to compare a 20-megapixel Canon EOS 7D Mark II with a 30-megapixel Canon EOS 5D Mark IV as an example. Newer cameras, both crop and full frame, can have even a higher resolution. Full frame sensors have somewhere between 24 million and 30 million pixels. Most crop sensors have resolutions that are somewhere between 18 million and 24 million pixels. Is a Crop From a Full Frame Sensor Better Concerning Resolution or Not? You still end up with enough pixels to make large prints, if necessary. If you want to crop 1.5x to imitate the image from a smaller sensor, you lose between 30% and 40% percent of the resolution. With the high pixel counts of modern sensors, that doesn’t have to be a problem whatsoever. When cropping a full frame image to have a larger magnification, we throw away resolution. You could shoot with a full frame and crop afterwards.
