A CODESILK app
SFBracket · For iPhone & iPad
Focus bracketing for Sony cameras, on autopilot.
SFBracket turns your iPhone or iPad into a focus-bracketing controller. Pick the number of frames, the step size and the direction. The app steps the lens, waits for it to settle and fires every frame, ready to stack into one image that is sharp from front to back.

FAQ
Frequently asked questions
What is focus bracketing?
Focus bracketing means taking a series of photos while moving the focus a little between each shot. Merging them, called focus stacking, gives one image that is sharp from the nearest to the farthest point. A single frame cannot do that at macro distances or with wide apertures.
Does SFBracket stack the photos for me?
SFBracket shoots the bracket and shows a low-resolution stack preview on your phone so you can check coverage. For the final full-resolution image, merge the files in desktop stacking software such as Helicon Focus, Zerene Stacker or Adobe Photoshop.
Which cameras work with SFBracket?
Sony cameras that support Bluetooth remote control or USB PC Remote, used with an autofocus lens. See the compatibility list on this page.
What is the difference between Bluetooth and USB?
Bluetooth is wireless step-and-shoot at roughly 1.5 to 3 frames per second. USB (PC Remote) is faster and more precise, and adds live view with focus peaking, the on-phone stack preview and burst mode.
How much does SFBracket Pro cost?
SFBracket is free to download. SFBracket Pro is a one-time purchase of $5.99 in the US, with no subscription. It supports Family Sharing and can be restored on a new device from Settings. Every new user gets 3 free Pro brackets to try it.
Does timelapse stacking run with the screen off?
No. Timelapse stacking repeats the bracket on an interval and needs SFBracket open in the foreground. Keep your device on power for long sessions.
Does SFBracket collect any data?
No. There is no account, no analytics, no ads and no tracking. SFBracket collects no data.
Is SFBracket made by Sony?
No. SFBracket is an independent app made by CODESILK. It is not affiliated with, endorsed or sponsored by Sony Group Corporation.
Your next stack starts with one tap.
