"You are using the camera mounted to the head using this L-bracket with a 200-400mm VR Nikkor fitted to the camera?"

Absolutely not! As you may know the 200-400 f4 and the 70-200 f2.8 are secured directly to the tripod head via a lens mounted collar. I posted those lens merely to illustrate the quality of lens I owned. Perhaps a bad example!

To the point and finally.

The Kirk L Bracket D200 fits on the D300 very securely and no further "bracket" is required. This was also true of the D200. I shoot virtually every day, primarily with a tripod. I received my D300 very early after release and have shot tens of thousands of images since. I also use a D3 but due to the environment I work in, I prefer the lighter camera. Hence I will pick up a new D700 next week. (Superior Image quality than D300 - lighter than D3).

The Kirk L bracket was designed to be used enabling the photographer to switch quickly from landscape orientation to portrait. 80% of all images sold to mags. are in portrait mode as you may know but I always shoot in both formats. I cannot see why you should think the L bracket requires any further attachment? How do you change format?

Anyway, I don`t hang around long on any forums, the odd look occasionally, no more.

Perhaps you could attach an image of how you use your L Bracket? As you know, non paying members are precluded from posing attachments.

Juat noticed your image! Thanks!
