Re: Dust in the chamber


I wasn't specifically blaming the 100-400L. The same thing happened again today. Another dust blob appeared after pointing the lens at the sky.

I am concerned about the level of unwanted attention and curious glances I received using this lens today. This is something I'm uncomfortable with and never happened with the 70-300 DO or even 70-200 f/4.

The 70-300 DO cannot officially take teleconverters but some have reported that a Kenko Pro 1.4 works with the pins taped.

Many thanks,
