Smaller pixels produce a sharper image.
Is more megapixels a bad thing if you have the same sensor size?
lets say you have two cameras with the same sensor size. One has 10.1 megapixels and the other has 6.1. Is the one with fewer megapixels actually better since they have the same sensor size?
- The newer one is better. The more expensive one is better. There is LOTS more to getting a good picture than the number of pixels.02
- Imagine the photo made of one dot, of a single colour. It's not very detailed, right? Now imagine an array of 100 dots, each of their own colour. You'd start to see bright and dark areas now, yeah? Now imagine 100,000 dots. You can see the picture.
The more dots (the higher the number of megapixels), the sharper the image.01
- Not all pixels are created equal... there is much more to it than just sensor size/pixels.
This would be like comparing the Nikon D100 and the Nikon D200, or the similar models on the Canon (or any other maker) side.
In this case, everything about the sensor and the rest of the camera is greatly improved. Better higher ISO response (still not good, but we are talking 12 year old gear here) better camera response, better processing speed, better JPG results out of camera... the list goes on.
If the progression of pixel count upgrades had continued like it once went, we'd all be using 50 or 60 MP cameras now. We aren't, and that's OK.
All else being equal, the newer technology will (almost) always outshine the older. Almost. Back then, it always did.23
- This MAY be possible for better ISO but you're probably better off with the higher megapixels00
- There's an ideal number of megapixels for a given sensor size. Technically, between 10MP and 6MP given that sensor sizes are the same, the former is much better. Now, if you push that same sensor size to say, 100MP, that would be terrible.
BTW, megapixels only tell picture size or resolution. The more MP, the bigger the picture so I don't mind shooting with my 6MP dSLR as long as I don't print bigger than a car. If I need bus-sized tarps, I'd use my 10MP camera. For most shoots, I'd reach for the nearest camera but when it comes to critical assigments, I have to use more MP to capture more details.20
- I have 10 of them00
- Hi definition is what this is about. a high definition picture can look clearer a low definition can be used to produce effects,
it really depends on what you want t achieve. really so time to investigate which is best for what you want to do.00
- Technically a camera with fewer pixels will produce a cleaner (less noise, better color, contrast) because as the number of pixels increase on the same size of sensor, therefore the pixel size must decrease. When the pixel size decreases so does the high-ISO performance and dynamic range of the sensor.
This was first discovered back in the early days of digital when cameras were going from 6MP to 8,10 and 12MP. People were noticing that yes, that they could print larger or crop in a lot larger and still maintain photo quality, but what they also noticed was that the noise was through the roof in comparison due to the higher ISOs required due to the smaller pixel size. You can see this today by comparing a 12MP Sony A7S to other cameras with much higher MP: https://www.dpreview.com/reviews/image-c...
How much of a decrease and whether that amount is too much of a sacrifice just to have more pixels really is dependent upon the size of the sensor and, of course, the end user. The larger the sensor, the larger the pixels are naturally going to be. So using a camera like the 50MP Canon 5DS R, while technically not as good at the high ISO settings as say a 24MP full-frame camera, the sensor size is already pretty large so the actual decrease wont' necessarily mean that you'll get unacceptable results.
