John - beautiful shots.

I have found and downloaded fCalc - I'll have to give it a run through tomorrow.

I've considered going to the zoo. Waiting for a free day and good weather - so I can take some shots outdoors.

I'm not sure Minolta zoom lenses work with an extender - I've checked but haven't been able to confirm either way. I've considered more than a few times getting a 300 prime and an extender.

There are a few blinds available throughout the refuge I shoot in - you have to register to use them and I haven't considered checking into it yet.

Jorge - thank you.


Thank you everyone - wonderful and helpful advice as always.
