This remote switch is designed to reduce camera shake to an absolute minimum. It is a perfect choice for taking long exposure photos. The remote has a two-stage release button, half-press to focus, fully press to trigger the shutter and take a photo. For long exposure, please press the release button fully and slide it into the locked position. The shutter will stay open as long as the shutter release button is locked. To unlock the shutter, just slide the release button back to its original position. This remote is powered by camera, you don't need to install a battery.</br> </br> Package includes:</br> </br> 1 x Remote Switch</br> 1 x 70cm long camera connection cord</br> 1 x 130cm long extension cord</br> </br> It replaces Canon RS-60E3 remote switch and is compatible with select Canon cameras as below:</br> </br> EOS Rebel XS(1000D)/T3(1100D)/T5(1200D)/T6(1300D)T7(1500D)</br> EOS Rebel SL1(100D)/SL2(200D)/SL3(250D)/XT(350D)/XTi(400D)/XSi(450D)/T1i(500D)/T2i(550D)/T3i(600D)/T4i(650D)/T5i(700D)/T6i(750D)/T6s(760D)/T7i(800D)/T8i(850D)</br> EOS 60D/60Da/70D/77D/80D/90D</br> EOS RP, R, R6, M6, M6 Mark II, M5</br> Powershot G10/G11/G12/G15/G16</br> Powershot G1X/G1X Mark II/G1X Mark III/G3X/G5X</br> Powershot SX50 HS/SX60 HS/SX70 HS</br> </br> It is also compatible with select Pentax cameras:</br> </br> K1/K3/K3 II/K5/K5 II/K5 IIs/K7/K30/K50</br> K10D/K20D/K100D/K100D Super/K110D/K200D/K500/645D/645Z</br> ist/ist D/ist DL/ist DL2/ist Ds/ist DS2/MZ-6/MZ-L/ZX-L
