OMD screen went blank when swopping between 20mmf1.7 and 45mmf1.8 lenses

[Alan Ang]

Don't you think the best solution is to go to olympus service centre and ask their guys to take a look at the camera and lens?
I think i will also be confused if i ever had that problem next time. Or call their line for technical support?

I just got the camera and the owner of the shop is my Neighbour. Hence, we are trying to isolate the problem to see if it's a camera issue or lens issue since it'll affect his future sales and service to his customers.

Also tried swapping oly lenses to c-lens and vice versa last night. Same issue.
Now it's beginning to sound like omd issue and not lenses...

I tried my 14mm F2.5 and 45mm F2.8 yesterday, swapping between them and the Oly lenses, no issues described here.

thank you for taking the effort to test this... now i have 2 people who confirmed no similar issues on omd. and 1 whom experienced the same previously but somehow resolved.

if it's a lemon, i will get a 1-to-1 exchange, so i am not so unduly worried. let's see what happens after my neighbour test it in his shop later in the day...

LoL... okok... let me recompose my scenario:

I switched off the camera. Swapped the 20mm to 45mm. Switched on the camera. And viola! The screen has the usual info at the bottom and the sides but no image... (almost like I never take of the lens cap but totally without the 'noisy' black)

Happened to me once when I was switching 20mm to 14mm on my friend's EPL2, very repeatable, never quite figured out what happened, but on my EPL2 it's all fine

sorry, do you mean repeatable or not repeatable? *a little confused*

i tried last night using my 20mm. I think is becuase you press the release button while attachig the lens.

test1
remove 12-50 from omd
attach the 20mm while pressing the release button.
turn camera on, screen is blank.

test2
remove 12-50 from omd
attach the 20mm without pressing the release button.
turn camera on, screen is fine.

Odd, shouldn't cause any problems but you're not supposed to press the release button when you attach the lens anyway (and you don't need too).

Step 1:

Unmount 20/1.7 and mount the 45/1.8 while NOT pressing on the release button. There is a CLINK sound and screen is good to go for shooting when power on.

Unmount the 45/1.8 and remount the 45/1.8 while pressing on the release button. There is no CLINK sound. Power on and the screen is black.

With camera on, turn the 45/1.8 like I will unmount the 45/1.8 a bit (this time without pressing release button). There is a CLINK sound. Screen is alive and good for shooting.

Repeat the same with 20/1.7, 25/1.4 and 7.5 FE, all the same issue.

My conclusion is, while pressing the release button, the lens overshot when mounting, causing the release lens mechanism to be blocked (which means lens is unmounted).

 

[theITguy]

When you remove lens u have have to hold the release button.

U have to let go release button before twisting-in the new lens. If u dont let go release button while twisting-in the lens got very good chance the alignment will be slightly out (over-twist). My OLED & EVF went blank. Had to remove & re-twist than ok

This is the advice think many of us missed

Why would somebody press the "release" button when mounting a lens at all? Funny.

Why would somebody press the "release" button when mounting a lens at all? Funny.

Because subconsciously, if something is used to lock and hold down the lens to the body, it seems logical to think that there is a locking mechanism that needs to be released first before one can slot in the lens.

Example:

Padlock that needs the key slots in to lock and unlock

vs

Padlock that does not need the key slots in to lock

yes,i know that too.
The test is only to prove to TS we are not suppose to press the release button while attaching lens.

i tried both with the release button pressed and un-pressed. same results.
for info: i started without pressing just like how i did with all other lenses... it works ok with my e-p3.
then i tried to do the same to my omd. it didn't work. so i tried pressing the release button since the catch seemed really tight... i thought it might help... anyway, it was dumb of me... it didn't work.

Seems like an isolated issue with the body. Get it checked.

yup. that's what we are thinking too... let see how the tests come up in the shop today.

 

[speedtest99]

did you try the 20mm on another camera?
If same problem then you can conclude it is the lens problem.

 

[ageha]

Is the 20mm F1.7 new as well?

it's in the shop now testing with other omd... results should be available tonight once my neighbour is back.

no. it's as old as my first PEN, the EPL1, when it first came out. but the firmware is latest...
