not hard with a good FF and good glass - Amazing shot.
This is what I am chasing. I watch the KelbyTraining stuff and see these photos they have on their card after a shoot and my jaw hits the floor. I mean, comparing just sharpness to sharpness its night and day different.
Is it the Full Frame? I mean is that the real key here? If you spend 5k you get an amazing image, but if you spend 2k you get really good, but not amazing?
Its a matter of learning the best settings for your equipment. Using a lens wide open will not result in optimum sharpness. Photography is all about light. As others have said, the right light makes a huge difference, I'd spend some time working with light. By this, I mean do not use that flash on your camera, get separate flash units off the camera, or better yet, other off camera lighting.
I made my own lighting using 4 ft cri 98 fluorescent lamps with electronic ballasts in 4 lamp fixtures. I have them above, to either side, and even below if needed, so there is usually 12 lamps going. I do have cloth diffusers to place over them when needed, and a light cube that will sit on the table to photograph reflective products like chrome objects.
Digital cameras love this type of light, its even and the right color temperature. The compact fluorescent bulbs can be a problem, but not high end tubes. I have to order them by the box of 25, you can't get them at a big box hardware store.
You can see my light table in this snapshot, I use it for product photography and have different colored backdrops that are wrapped around a piece of rigid foam, so I can pop them in place quickly. I have a pc that I tether to my camera, and a tripod head bolted to a massive steel angle on the front of the table for close shots.
No need to spend hundreds of dollars for lighting. I do have several stand mounted lights, but they mostly sit in storage because my table does all of my products.
