Please look at this photo below, on the left is the full product, and on the right is the 100% crop of the same photo.
The guitar is around 100cm tall. If you incline by around 45°, you have about 70cm of depth of field.
As you can see, the photo has perfect focus from top to bottom.
My setup for product photography (with strobes) is usually 1/160, f/9 to 11, ISO 100, on Nikon D850 with a 24-70mm lens, and I could never be able to obtain that sharpness and that depth of field.
What do you think is the setup for this very long and sharp depth of field?
I don't think that it is a case of focus stacking because of expensive post-production. They have "millions" of products, I don't think they do focus stacking for productivity reasons.
Do you think that it could be a 150-200mm zoom lens and shoot from a certain distance?
I thought about wide-angle lenses (10-15mm)m but the product looks too "flat" for a wide angle (unless they apply lens corrections), but I could be wrong.
