I'm looking to buy Nikkor 40mm 2.8 for jewelry photography but everyone keeps saying that focal length is too less which makes minimum focus distance less too. So if I take jewelry pics and I'm not close to the minimum focus distance but a little further from the minimum focus distance, will it effect the pictures quality? I will be using the focus stacking technique.
