Costco sells plenty of good products.
It appears that Nikon has the ability to make these in large quantities
and is choosing many avenues for selling them.
Personally I think it is wonderful that this level of IQ is being made so readily available
and at such a great price.
This leads to photographers having less overhead while still being able to offer great quality.
It is kind of interesting going to buy bulk house hold items, janitorial supplies for the studio... throwing them all into the cart and then topping off
the cart with a D600
I actually find it interesting that this level of camera is getting into just about everyone's hands.
While some think that they need to have a better camera than their client or uncle Bob, I think it works the other way too.
Working with the same camera as Uncle Bob or your client actually highlights your skill as a photographer
because the results are not attributed to you having a better bigger meaner camera but to your skills.
