I totally agree - some of you are getting out standing shots and I am still just not getting those really sharp images. If at least you could post your settings that might help. Am I correct in assuming that the greater the zoom the shorter the depth of field? If so how are you able to catch such detail on the planes and birds?
If I am using my 55-250 extended to 250 for photographing plants or wildlife, I would set the camera to AV with an aperture as wide as possible, f4 up to f6.3, that will make the point of focus clear, but the background will be blurred, because with those setting you will have a shallow depth of field.
On a dull day with aperture settings greater than f6.3, the 55-250 will set the camera to a slow shutter speed. I have found that shutter speeds less than 1/160 sec will probably cause blurred photographs from camera shake, despite the image stabilization. A good tripod always helps in low light
These are my own experiences with this lens and are very basic. If any regular has anything to add, please feel free to do so.
At f4 the 55-250 is not a fast lens, but with a little perseverance it is capable of some decent results.
There are some great tutorials on this forum for anyone who wants further reading.
Regarding the settings I have used for my photographs posted on this forum. I use Flickr and all of the Exif is in tact. To obtain this info, click on the photo which will take you to my Flickr page, above the photo is an "Actions" tab, click on that and you get a drop-down list, Exif is about 2/3 down the list. That will give you all of the info you require.
Good luck and keep snapping.
