Today’s Post by Mark Toal
One of my favorite mirrorless lenses is the Olympus 9mm Fisheye Body Cap lens and I’ve written about using it to photograph cars—pros and cons—on my car photograph site/blog. Today Mirrorless Photo Tips’ Mark Toal takes another look at this interesting and affordable lens and shares some tips and techniques.
A few weeks ago I had a chance to try the new Olympus 9mm Fisheye Body Cap lens. For $85 you get a 18mm equivalent, manual focusing, f/8 lens that’s fun to use. I’ve been using it on my Panasonic Lumix GX7 with focus peaking feature. The lens only has three focus settings so focus peaking comes in handy so you can see what’s going to be in focus. The combination of 9mm at f/8 also gives extreme depth-of-field. Make sure you go into the menu on your Micro Four-thirds camera and turn on the “Shoot Without Lens” option since this lens has no electronics to communicate with the camera.
Since this is a full frame fisheye lens you will see quite a bit of distortion in the images coming out of the camera. My friend and Portland photographer, Jerome Hart, showed me a simple trick to correct distortion in RAW files from either the Olympus 9mm or the Lumix 8mm lens by using Adobe Lightroom. In Lightroom’s develop mode go to Lens Correction > Profile > Custom> Make: Sigma > Model: Sigma 10mm f/2.8 fisheye and watch the distortion disappear. See below.
