[QUOTE="RobV, post: 576848, member: 40570"] I have one of the older AF 300mm f4 from Nikon, the [url]http://nikonites.com/products/telephoto-5/nikkor-300mm-f4-af-367/[/url]. It does have an aperture ring which when unlocked, will stay in place when off the camera. It uses a body with a built in focusing motor for AF, and does not have VR. It is a nice lens. Those are some very nice pictures! Enough DOF to get the entire insect and plant in focus. That information is called EXIF ( [URL="https://en.wikipedia.org/wiki/Exif"]https://en.wikipedia.org/wiki/Exif[/URL] ). Sometimes it takes a moment to add that to the image. All three of your shots are showing it now. There are also situations where post processing removes the EXIF data from the image file. I have also seen some images on here that had more information than the average file. This is as much as I have learned in one year. I also found out this EXIF data can be seen on a Windows photo viewer. Open an image, click on: File Properties Details Some of these fields can be manipulated. There are also 5 stars if you want to rate them. Have fun! [/QUOTE]
