Mounting and Detaching the Lens

Focusing

Choose  the  corresponding  lens  mount  according  to  your  camera 
body,  and  refer  to  your  camera’s  instructions  on  mounting  and 
detaching the lens. 

Method 1: Magnification Priority 
1. Set the magnification first. Turn the focus ring to the required 
magnification. 
2.  Focus  the  subject  roughly.  While  looking  thorough  the 
viewfinder or using live view, move the camera back or forward 
to find the proper focus. 
3. Focus the subject finely. Turn the focus ring to get sharp focus. 
Method 2: Framing Priority 
While looking through the viewfinder or using live view to frame 
and focus, turn the focus ring, frame the subject and then follow 
steps 2 and 3 above.

Turn the focus ring on the lens to get focus as LAOWA is a MF lens. 
There are two ways of focusing, you can give priority to 
magnification or to framing. 

Focusing Instructions

Limited to close-up shots,it allows a focusing distance range of 173.0mm to 
223.8mm and can not focus to infinity. 
Gently turn the focus ring to prevent the focus mechanism from damage.

When making high magnification shots, please shoot carefully because you are 
so close to the subject under the extremely short working distance. 
Magnification refers to the ratio between the subject’s size in reality and

the size of the subject’s projection on the image sensor. 

To prevent camera shake, using the tripod, shutter release, mirror lock-up and 
silent mode are recommended. 
When shooting as method 1 (magnification priority), a focusing rail slider will 
make focusing easier.
For high magnification shots, the actual aperture will becomes darker, so 
please refer to exposure compensation table to make adjustments accordingly. 
To reduce shake when shooting, please use a tripod and a flash. 
Manual exposure mode is recommended to obtain accurate exposure.
