Are you struggling to get sharp images with your super-telephoto lens, even when you use a tripod? Your problem is due to mirror bounce. In this quick guide we’ll show you four simple ways you can keep it at bay.
As with macro photography, stillness of the camera is vital when using long lenses. A rigid tripod is a big help, but mirror-bounce can be a problem with DSLR cameras. This is because the action of the reflex mirror flipping up immediately prior to the exposure can blur the results.
Most DSLRs have a mirror lockup feature, available via shooting menus, custom functions, or as a dedicated drive mode. If you use this with a remote controller, the initial full press of the remote shutter button will only raise the reflex mirror. You can then wait a couple of seconds or so before pressing the button again to release the shutter.
How to beat mirror bounce
1 Mirror lockup
In most entry-level Canon SLRs, mirror lockup is available as a custom function. On more advanced bodies, it’s available via one of the shooting menus.
If you don’t have a remote controller, Canon’s two-second self-timer drive mode works very well in conjunction with the mirror lockup function.
3 Mirror up
Nikon’s mirror up function works in the same way as in Canon cameras, but is available from the drive mode and cannot be used with a self-timer delay.
4 Exposure delay
For those without a remote controller, the exposure delay mode applies a one-second delay after the mirror flips up. Some bodies give options for longer periods of delay.
