Thank you Thijs, in summary what you suggest is to narrow my search for a full sensor body such as your D5200. My present goal in photography is just to record the many levels of beauty that are weaved into a garden and its flowers and be able to share that with my gardener peers. I'm not interested in photography as such or an end in itself, although I fully appreciate a high quality picture both technical and artistic wise. Simply I'm a gardener at heart and perhaps eventually a teacher sharing what I know or "see". Also technology is just too much for me and at times it simply goes beyond my rather poor comprehension. Thus with the manual lenses that I own, including a 300mm telephoto ( for the small birds that share our life here) and a common lensI have enough versatility for what I am accustomed to. I guess that with your added comments I should look into your D5200 or simmilar models.
