35 mm film size is called a 1x crop factor. The Field of View W×H dimensions vary with aspect ratio, but "same Field of View" here means the image diagonal is the same dimension (the lens image circle is the same size.) Using this 3rd calculator for Equivalent Focal Length, you ...
但是,当图像传感器尺寸变小时,镜头的有效焦点也会变小。与原始尺寸相比图像变小的量称为“裁剪因子(Crop Factor)”,也叫焦距转换率。 Crop Factor 如何影响树莓派 HQ Camera 的镜头的? 树莓派 HQ Camera 使用的图像传感器大小为 1/2.3 英寸,Corp factor(焦距转换率)为 5.6。如下图: 例如,为树莓派 HQ Camera...
1) Do EF-S lenses need to have the 1.6x factor applied for effective focal length or are they marked correctly since they can only be used in APS-C cameras? E.G. My 17-40mm EF 4L lens is effectively a 27.2-64mm when used in a EF-S mount camera due to the 1.6x facto...
There is no such thing as “crop glass”. (Bubble has been burst.) Thereissuch a thing as a lens that sits too close to the mirror and isn’t physically large enough to cover the entire sensor. Switch sensor and you switch angle of view, but the mount or crop factor matter ZERO to...
the 1.125° grid in which the 0.5° grid was included. If a 0.5° grid straddled multiple 1.125° grids, the average value of these 1.125° grids was used. PRYSBI2 data do not distinguish irrigated and rainfed production as irrigation is subsumed in the technology factor as described above....
“crop factor” – the ratio of 35mm film diagonal to the APS-C sensor diagonal. Nikon’s APS-C sensors measuring 24x16mm have a diagonal of 29mm, while full-frame sensors measuring 36×24 have a diagonal of 43mm, so the ratio difference between the two is approximately 1.5x. Canon’...

Using the Erosion Productivity Impact Calculator, simulated yields of wheat (Triticum aestivum L.), maize (Zea mays L.), and soybean [Glycine max (L.) Merr.] were significantly different when using the measured and uncorrected solar irradiance; however, the yields were not signi...
In models that assume nitrogen is not a limiting factor, climate change impacts are generally somewhat less severe and CO2 fertilization effects are generally more positive, meaning that yields in many areas are projected to increase [Rosenzweig et al., 2013a]. This is especially true in...
