Yes, you read that headline right! The D90 (body only) is showing available to ship Same Day at Calumet’s website. Now, that doesn’t mean that it will be available in all of their stores yet, but you can certainly order it from their website and here’s the link.
I haven’t seen it in stock anywhere else yet in the U.S. and I was really shocked to see it in stock at all! B&H and Adorama should have it in stock soon if Calumet has it.
