On résume souvent cela à la notion de piqué de l’objectif qui atteint son maximum à des ouvertures de F5.6-F8 pour la plupart des optiques
Plus le pouvoir de résolution est élevé, plus on pourra voir de détail sur l’image finale jusqu’à atteindre le nombre de Mpix du capteur Le pouvoir de résolution d’une optique est mesurée par sa capacité de différentier deux lignes ou points d’un objet. Le Sony A7RIV avec ses 61Mpix ne vous donnera pas de meilleur résultat que les 42Mpix du A7RIII ou les 24Mpix du A7III si vos optiques ne peuvent résoudre une telle densité de pixel So before buying/upgrading to an A7RIV check the lenses you have or should buy, for many people a A7IV, A7III or A7RIII could be a better optionġ.1 Obtenir la quintessence du capteur de 61Mpix You can still take great photos at 1/60sec and 6400 ISO but this won’t be better than on a 24 Mpix camera Most lens have enough resolving power for the density of a 24Mpix full frame sensor but the A7RIV with is crazy high pixel density is torturing the lenses and there are very few that can reveal the full potential of the sensorĪlso this full potential will only be achieved in ideal conditions with speed of min 1/250 handled and low ISO < 800 ISO This is summarized in the “Sharpness of the lens” with in general reach its max at Aperture around F5.6-F8 for any lens The greater the resolving power, the more details will be visible on your final image up to the number of Mpix of you sensor The resolving power of a lens is measured by its ability to differentiate two lines or points in an object. The Sony A7RIV with its 61Mpix will not give you better results than the 42Mpix of the A7RIII or the 33Mpix of the A7IV or the 24Mpix of the A7III if your lenses can not resolve such a high pixel density The resolution is just a bonus, but blows my mind when I capture a little something special which can be recompose in post.Īs if I were so good I captured the exposure intentionally.1 Introduction 1.1 Getting the most of the sensor of the A7RIV But this tool has definitely “upped” my skills to a level I hadn’t though possible. knowing I have this flexibility is extremely liberating.Īs I grow as a photographer, I find néw and exciting ways to properly customize my camera.ĭo I feel as if I am the best photographer? Of course not. It is customized to my style of stills and video. But I feel quite confident no other camera is configured quite like mine is. Once all of my customers menus were dialed in, it became a part of me. Who has an actual relationship with their gear? I never had.Īfter a year, the camera feels as if it is an extension of my arm. It felt as though, from that day on, this camera and I had made a pact to create some mind-blowing and work. It felt as though the camera was shaking my hand. R=Resolution The first time is held the new grip, I smiled.
