At longer focal lengths you will have to stop down.Ĭonsult a depth of field table, such as this one. At the widest setting (smallest focal length, f = 9 mm, 24 mm equivalent) it can do it at ALL aperture settings, even f/2.8. The FZ1000 cannot, or if it can I don't know how to do it. I am looking for a point and shoot camera that is roughly in the same category as the Panasonic Lumix DMC FZ1000 - but can take photos with depth of field between 2 and 4 feet out. You may need to use focus stacking to make multiple exposures to be stacked and merged to capture your subject in good detail in a single finished image. The FZ1000 focused on a subject 5-feet (1.5 meters) distant at 50mm, f/11 makes a photo having about a 9-inch (23 cm) DOF. Whether or not you'll be able to capture your subject in good detail in a single photo will be contingent on your distance to the subject and the entrance pupil diameter of the lens. That's the f-stop that will deliver the deepest DOF image to the sensor. To achieve that, you'll want to use a larger f-number. It's a smaller entrance pupil that will increase DOF. So, while using a smaller aperture will deliver greater DOF, it's not a smaller f-number (f/2, f/1.8, etc) that increases depth of field. The wider the entrance pupil, the shallower the DOF of the image. At the longest end of the zoom, 146mm, its entrance pupil can be as large as (146/4=36.5) 36.5mm. At the shortest focal length of 9.1mm, the lens can work with an (9.1/2.8=3.5) 3.5mm entrance pupil. f/2.8-4 indicates the widest aperture for the FZ1000's lens along its zoom range. Since the amount of light delivered to the sensor and depth of field (DOF) in the photo are determined, in part, by the size of the lens entrance pupil, lenses are typically marketed by their widest aperture their smallest f-number. The smaller the f-number, the wider the lens aperture the entrance pupil diameter. Unfortunately, many associate the term, aperture, with the f-number as opposed to the entrance pupil diameter and this sometimes leads to confusion.įor example, your FZ1000 is marketed as having a 25-400mm (full-frame equivalent) f/2.8-4 zoom lens. The camera's f-stop is an equation for calculating the diameter of the lens's entrance pupil. The camera nearest to what you want would be the fz1000ii or fz2000/2500 which have focus stacking and a minimum focus distance of 1 metre shooting with a wider focal length then much closer distance is possible. Panasonic have added a photo mode that’s called focus stacking which would make this possible but it also depends on which focal length you use as you will come against the minimum focus distance as well. So you want more in focus when capturing a subject 2 to 4 feet away from the camera ? Note that the newer FZ1000-II has f/11, (for a slightly deeper DOF). you said you dropped it, I wonder if there is a possibility of a loose lens-element ? But be sure you have a high-enough ISO so your Shutter-Speed won't be too long - and give "shaky" images.īUT. So I second the suggestion of using "A" (priority) to manually set f/8, (and the Shutter-Speed will be automatic). The deepest DOF on FZ1000 is f/8, (f/2.8 is the shallowest). Sound like you are looking for a "deep" DOF, (as opposed to "shallow"). I can't find a suitable camera with a smaller aperture than 2.8. I need to photograph products and have them in focus from front to back. ![]() ![]() I dropped the camera some time back and not all functions are still working, so possibly this is my fault. ![]()
