DMC-FZ150 versus DMC-FZ300

For years, my go-to camera kit for photowalking has been the Panasonic Lumix DMC-FZ150 superzoom digital camera and a Canon 580EX Speedlite. A formula of camera and flash settings that I call “set it and forget it” works most of the time, enabling me to focus on the subject rather than futzing around with camera/flash settings.

My new Panasonic Lumix DMC-FZ300 features some significant upgrades over the DMC-FZ150 such as a touch-screen LCD, built-in WiFi (enabling remote control of the camera using the “Panasonic Image App“), 49 focus points, 4K video, and an intriguing new feature that Panasonic calls “Post Focus.”

The two cameras are similar, but as I say often, similar is not the same. As appealing as the new features of the FZ300 are, the newer camera doesn’t perform like my older FZ150. After limited testing in both the studio and in the field, I have yet to find the new formula for “set it and forget it” using the FZ300. Disappointed and frustrated, I am!

A Springtime Darner dragonfly (Basiaeschna janata) was spotted along Popes Head Creek at Hemlock Overlook Regional Park, Fairfax County, Virginia USA. This individual is a male.

108mm (600mm, 35mm equivalent) | ISO 100 | f/5.2 | 1/800 s | -1 ev

Flash fired, in compulsory flash mode. My external flash unit is set for Manual mode at a power ratio of 1/16, plus or minus one stop. The other settings listed in the photo caption are typical of what I call “set it and forget it,” that is, these settings work for most subjects in most lighting conditions.

The preceding photo was included in my “Top 10 Photos of 2018.” Many, if not most, of the photos in this gallery were taken using the DMC-FZ150 and my “set it and forget it” formula.

A Brown Spiketail dragonfly (Cordulegaster bilineata) was spotted at Occoquan Regional Park, Fairfax County, Virginia USA. This individual is a male.

108mm (600mm, 35mm equivalent) | ISO 100 | f/2.8 | 1/800 s | 1 ev

Flash fired, in compulsory flash mode.

A Common Green Darner dragonfly (Anax junius) was spotted at the North Tract of Patuxent Research Refuge, Anne Arundel County, Maryland USA. This individual is a female.

A Harlequin Darner dragonfly (Gomphaeschna furcillata) was spotted at the North Tract of Patuxent Research Refuge, Anne Arundel County, Maryland USA. This individual is a female.

What are the take-aways?

I prefer shooting in Shutter Priority mode at relatively fast shutter speeds (using the reciprocal rule) in order to reduce camera shake at longer focal lengths. If the ISO is set for 100 then the exposure triangle tells us that the only variable is aperture (f/stop). Using my “set it and forget it” formula of settings, the FZ150 typically opts for an f/stop of f/5.6 or higher (that is, a smaller lens opening); for some reason the FZ300 always seems to opt for f/2.8.

Problem is, there is too little depth of field at f/2.8! The only way I’m able to shoot serviceable photos using the FZ300 is to compose photos so the entire subject is nearly parallel to the focal plane and to sharpen the images using Adobe Photoshop.

I’m planning to start shooting in Manual mode so that I can set the ISO, aperture, and shutter speed. During limited testing in the studio, it was necessary to use a higher flash power ratio in order to get good exposure. Otherwise, Manual mode is the ultimate in “set it and forget it!”
