With a 7D, you need to address IQ-diminishing factors more aggressively. The large pixels of the 1D X are more forgiving of optical aberrations and a small amount of camera shake, as the effects can be largely contained within a single pixel. The smaller the pixel pitch, the more magnified the effects of camera shake, poor lens quality, or improper AF micro focus adjustment will be. In terms of line pairs per millimeter (lp/mm), assuming the same focal length, same sufficiently wide aperture (say f/4), and subject distance.the 7D is capable of resolving details 61% smaller than the 1D X is capable of. The 7D's luminance spatial resolution is just shy of 116 lp/mm, where as the 1D X, despite having the same number of pixels, has a spatial resolution of 72 lp/mm. The 7D's 18 megapixels differs a lot from, say, the 1D X's 18 megapixels.in terms of spatial resolution. Megapixels and Line PairsĪ simple scalar number doesn't tell you the whole story though. When compared on a megapixels basis, 18mp doesn't sound like much.the 1D X has 18mp, the 5D III has 22mp, the D800 has 36.3mp.

You will need a FoCal account, which can be created for free from within the app.The Canon 7D is a very demanding camera, with a particularly demanding sensor. FoCal requires the use of a FoCal Target, which you can download and print using links from within the app, or purchase from the FoCal store.

For iPad with USB-C, you can directly connect to the camera with just an appropriate cable. For iPhone and iPad with lightning connectors, you will require a Lightning to USB Adapter in order to connect a camera - further details are provided in the app help, but a standard Lightning to USB adapter will workin most cases. * Connection is via USB or the Reikan Wireless Camera Control Module. Calibrate and analyse lenses with focal lengths over 400mm.

One-tap Time Sync - synchronise your camera time with one tap right from the first screen of FoCal. Export data to FoCal Pro Desktop for more detailed analysis, charting, reports and more. Review historical data, recall tests and calibrations you've run to find out how your equipment is holding up. FoCal Comparison Database: compare the performance of your kit with 1,000s of other users to find out how it compares to *real-world* use, NOT artificial lab tests! Check your autofocus with cameras that have already been calibrated. Get the very best from your camera and lenses.
