My interest is photographing birds and I use a Nikon D5600 usually with a Sigma 150-600mm lens. As I tend to mix my photography with walking I don't usually use a tripod. I have Parkinson's and therefore can sometimes struggle to keep a steady hand when taking shots. I've been considering looking at a bridge with a good zoom but have been put off by comments regarding poor image quality with a bridge as opposed to a DSLR. I tend to photograph at a good distance as I do not wish to disturb the bird so need the zoom. Any help and guidance would be much appreciated (obviously other than move nearer)
