Sigma SD15 + 18-50mm f/2.8-4.5 DC OS HSM lens

Remote control allows the photographer to take self portraits or get into group shots. Used in conjunction with Mirror Lock-up function, it can reduce the possibility of image-blurring camera shake. It is very useful for macro or telephoto zoom shooting. It features 3 frequencies and 2 delay times.
