thanks for the comments and i agree about the lens i am hoping soon to get the sigma 50-500 or bigma as they call it and as i take on average about 150-200 shots per day not every day of course as i have to work to pay for this hobby

and if i get three out of that i am absolutely delighted
i try to put the picture on with only the basic touching up in picasa ie cropping,filling light,highlighting and colour adjustment .i have put some pictures through neat image but i am never completely satisfied with them most of the pics were taken at the long end(is that how you say it?) and still heavily cropped my lens is 300 and if i can get close enough i will try to extend it as far as is needed without going above the f4.5 as in this shot of a reed bunting i had the camera set on tav for shutter and aperture priority where the focal length was 220 the iso was automatic at 400 and the exposure 1/180 and apart from the noise it came out reasonably ok but i may try it through neat image to see if it can be improved
cheers
