Before you invest money in what you think is the perfect lens that will make all your photography dreams come true, you should know that the best lens for food and product photography is likely the lens you have right now.
Yes, you should know a bit about camera lenses if you are planning to shoot with a DSLR or a mirrorless camera with interchangeable lenses. For example, don’t get a monster telephoto lens for shooting food in a small space. I trust you could have figured that one out on your own, though.
Beyond that, creating the photos you envision is far less about the lens than it is you mastering how to best use it.
I use three lenses regularly (I’m on team Canon, by the way):
24-105 mm, f/4.0
100 mm macro
50 mm, f/1.4
Now let me show you why you could pick any one of these lenses and create a similar photo.
Yes, there are slight differences in these images, but not so drastic that it calls for you investing in a new lens when you are not ready, or spending beyond your means thinking a lens will change everything.
There are three factors that will have a stronger impact on creating the images you envision.
Gaining an intimate knowledge of your photo space and how the light moves throughout the day.
Controlling natural light and creating directional light.
Styling with props and surfaces that are fully aligned with your style.
Do these three things successfully and you’ll see positive changes in the pictures you take with the lens you have now. And it’s a far less expensive investment than dropping several hundred to several thousand dollars on a new lens.
Sure, eventually you outgrow gear and you’ll be ready to try something new. For now, focus on changing your mindset and the belief that you aren’t happy with your photos simply because you don’t have the right lens. Work on building your creative skills first and leave the tech for later.
