First of all can I thank you all for the replies. There is a good reason why I asked. If you missed my other posts I was on the point of throwing the camera out, the focus was terrible. No matter what I did it never improved. Changed lenses- swapped with another camera no problem, it drove me mad honest, and frustrated.
found the answer with Steve Perry's youtube post, it was down the the AF sensors, never crossed my mind.
So now the reason for posting the photo. Having "cleaned" the AF sensor with old round sponge swabs it improved the focus somewhat but yesterday I got new ones so "clean" the AF sensors again and now able to post the above. OK not dead on sharp as the plant was waving in the wind but this time use a longer lens as well, (a Nikon 24-70 f2.8 G.)
So the above is really a test to see if I am capable of doing better. so I was quite pleased with this hand held shot, ok more practise now i know what the problem was.
So thanks all again for your suggestions and replies much appreciated
