I agree with you wholeheartedly. The I used to be on Flickr, I saw some amazing images from older, and /or less expensive cameras and lenses. It is NOT hte equipment, it is the person behind the lens that makes or breaks an image,

BTW, when I shot with Nikons, I also had that Tammy lens and loved it.

I would try Roberts in Indianapolis. I have dealt with them for years and they are honest, and have wonderful service. Abe's has always had bad reviews

I have not bought anything from them for quite a few years, but I was very happy with the service and the pricing seemed fair.
