Glad to help. That's correct: you're on the original firmware. The  
green button 'semi-automatic stop down metering' for pre-A series  
lenses was an add-on to the original *ist D, I think it surfaced in  
firmware v1.02 or something like that. So you definitely need to get  
the fw update installed to get more functionality out of those lenses.

You can use them in Av mode now, however. Just be aware that they  
will only be wide open ... the Av mode will assume they don't have an  
iris diaphragm and will base exposure metering on the light  
transmitted through them wide open.

Adobe Photoshop Lightroom is downloadable for a 30 day free trial from:
   http://www.adobe.com/products/photoshoplightroom/

Of course, you need a computer for that too... If you're running a  
Windows system, be sure that you have a Pentium IV or V or later, 1 G  
RAM and a good bit of hard disk space. Lightroom is a fairly  
intensive image processing program and needs pretty up to date  
hardware to work respectably.
