Nikon D80 和 Canon 400D 都是膠殼機身, 配置遠程鏡頭會否使機身容易破爛 ?
of course not, either people will use sturdy/strong professional TRIPOD like
the one below ... or we use monopod to hold it like the next picture :)
如何防止機身破爛 ? you won't even touch the camera anyway, since it becomes SO SMALL compare to the lens :)
Bigma (sigma 500mm) or Canon 200mm USM/IS f/2.8 are
popular choice ... (they are quite expensive :P)
