So, Why FF ?
Seems to me that FF is all about connectng back to the old 35 mm film
format, and very little else, since smaller sensors with the same pixcel count in conjunction with shorter lenses could do the same thing, BUT smaller and lighter. What part have I got wrong ? |

What part have I got wrong ? just about everything. full frame sensors produce images with higher image quality, lower noise, wider dynamic range and/or higher resolution, and the lenses aren't necessarily bigger. so no, a crop sensor can't 'do the same thing'. some people might not notice or care, but that's something else entirely. |

My question assumes shorter lenses to yield the same image. Nothing cropped. and the lenses aren't necessarily bigger. Not true, under the above premise. |

My question assumes shorter lenses to yield the same image. Nothing cropped. and the lenses aren't necessarily bigger. Not true, under the above premise. there are many variables, most of which people ignore. for the same image quality, a micro 4/3rds sensor lens must be two stops faster than its full frame counterpart, making it bigger and more expensive, and in some cases, physically impossible. |

What part have I got wrong ? Nothing! For many years M43, and APS-C have exceeded the capability of 35mm film, as have some of the small sensors found in the better performing Smart phones. However, there are some characteristics of modern FF sensors such as DoF, and low light performance which only a handful of APS-C sensors can come close to. In the end many of the FF pundits have failed when it comes to discerning the source of a well made print from FF, M43, APS-C, or even a late model iPhone or Android phone. to each his own. I prefer FF for landscape and/or WA shots. For wildlife I prefer my D500. Use what you like, but understand why you are using it. I do, and I do. -- Regards, Savageduck |

What part have I got wrong ? I think it's connecting back to the 35mm lenses that people have and like that part is true. but are compromised when used with smaller sensors. that part is not. there is no compromise in using a full frame lens on a smaller sensor. it's actually *better*. Although the larger sensor cell area has a better signal to noise ratio, most prints won't expose those differences if the pixel counts are the same. some do, and prints aren't the only output medium. hdr displays come to mind. |
