Finally sold my Sigma lens and for a good price... Will be saving my money for a new old lens this fall. I have decided to buy a Nikkor 500 mm f/4 ais or p lens. A couple just sold on the big bay for around 2300.00 so it's going to take a while. This summers metal detecting should take care of it but until then I will have to use my 80-200 and kit lens.. here is a Catbird taken with the 80-200
