Mbali yothandiza ya 7D ndikuti pulogalamu yowonjezera yowonjezera ikugwiranso ntchito yotumiza Speedlite. Izi zikutanthauza kuti kamera ikhoza kuyendetsa makamera osatsegula, posonyeza kuwala.
Quality Image
Mtengo wa zithunzi pa 7D ndi wabwino kwambiri kudutsa lonse la ISO . Pansi pa ISO, khalidwe lachifanizo ndilopadera kwa kamera iyi ya kamera. Chinthu chokha chomwe chingawononge kamera iyi pa khalidwe ndi lens yotsika mtengo!
Kamera imapanganso bwino pazigawo zochepa. Magazini yokhayo ndi khalidwe ndi kamera kachitidwe kowonjezereka kovuta kwambiri. Komabe, ngakhale izi zingapeŵe kwambiri ngati mutaponya mu RAW.
