So i dug out my Xt1 and 35mm f1.4 from the camera bag after months of neglect. and lo and behold, my acc door is bowed, the leatherette is peeling... the Ael and Afl buttons have seized!! they are solid, i can NOT push them down. now the last shoot i did was near the beach, but no water got on the camera, nor did it fall in the sand. isnt this thing weather sealed? how could something get under the button to cause it to seize? i now that no weather sealing is perfect, but its not like i had dunked the thing in water, it was simply walking around by the seaside. the camera was bought used and is now long out of warranty. so does anyone have any idea?
