I got out today to use my new 5100 and enjoyed it however the pictures we took of some eagles nesting and flying were a bit disapointing. I may be expecting too much also. But when I compared the sharpness of an image taken with a bridge camera (Canon SX40HS) the sharpness appeared to be slightly better in the Canon.
I can understand the difference because of the different focal length.However just selecting an area of equivelent pixel size or in the windows photo gallery and viewing full size shows.
I had the lens AF on and the image stabilization set. I also rested against a fence for many of the shots. At 1st I thought it may have been related to a low shutter speed (1/200th ish)
Below is one of the pictures. No post processing or cropping.But I would imagine its resized when uploaded so you may not be able to tell anything.
I just figured with a larger sensor and more resolution things would look a bit better.
Of course with the other camera I wouldn't have been able to get some of the pictures of them flying. It's great having the shutter go off right when you push the button.
