the focus screen on
an Olympus E510
old lens MF through the adapter, it
might be useful to have a focus screen "old style" with central broken
image and crown of Microprism (like on old OM system body) so when I
discovered the existence of this kind of focusing screen specific for
E-System, I bought it immediatly and proceeded to the replacement
on my E-510 : I was happy because with the benefits derived from the
replacement I have solved every problem of manually focusing with
optical not auto & dedicated .
The operation is simple and and requires only attention and "gently"
... For this reason I decided to make (and publish) this guide.
N.B. : I MUST HOWEVER REMEMBER YOU THAT I WILL NOT BE RESPONSIBLE FOR
POSSIBLE DAMAGE THAT YOU SHOULD CAN MAKE
place the body in a stable and convenient position for operations.
(Click on each image you will have a magnification of the same)
Use only plastic tools (or terminals coated with rubber) to avoid any
damage to the parts of your Olympus.
The display of focus is locked by a small (and delicate so make more
frame that you can un-lock with a slight (and very little) pressure on
the point highlighted by the arrow, in the same direction indicated by
Once released, the frame is ready to be extracted with a pair of
tweezers : lift the front and pull out from the two rear embeddings
(continuing on the page you will find a detailed image of the chassis
that should be be useful to see).
At this point you will be in the condition shown in the picture: the
screen to focus is "free" and ready to be extracted.
Remember the position of the notch on the right side at the top of the
mirror: you'll need it as a reference when You'll put the new one.
Before you can take the mirror (to be replaced) with tweezers, you must
lift it from one side as shown in photos
Once grasped and gently extract from the E-510, the original screen
must be put in a safe place (the box of the new focus screen that you
have just purchased for the replacement is very good) because it is a
Be careful because under the focus screen there is a second
frame, simply "placed" in terms of thickness: you see in the picture.
In the picture, you see also the reference to be considered in cases
where the chassis had to be relocated after his accidental displacement
This could happen for example by blowing with a blower to remove dust
(before put the new screen focus), but there is not problem because
simply you must reposition it making referernce to the small pin that
you see indicated by the arrow.
Now start the "reverse journey" : You must "place" the new focus screen
in the same position of the "original" ... with the same delicacy and
gently used for extraction.
For his correct positioning, refer to the mark on right side up (look
the arrow in the image...)
And then is the time f the frame that holds the focus screen locked: in
the photos are highlighted the notches of reference of the joints, but
be careful because in the picture the frame is turned (below-above) to
give you the way to see clearly of which notches I'm talking
Before enter the two rear notches in their two "home" (look the red
arrow), then started to push down gently the front of the frame to take
the notch near his "home".
Then push the frame slightly in the direction of the arrow allowing the
front mark to come back in his home (just like you had done to liberate
it), blocking the frame and everything else ... this is the end of the
It 's not necessary, but if you have an antistatic cloth (like those
used for the negative film) use it to clean the new focus screen
before mounting it ... this help to remove dust
or other "noise" .
