Any other E-M1 users notice that the default color profile is not very saturated? Or is it only me?
OMG! Look at the EM-1 aka the now official E-M1 Thread

Did you put the focus ring on the lens back to autofocus position?
Updated: Thanks to undergrd for solving my problem. I just realised that my lens has nice feature where I can pull the focus ring back and be in manual focus mode.

Glad to hear that. :thumbsup::thumbsup::thumbsup:
I just bought with the 12-40mm kit lens. Frankly I was disappointed. Not with the camera but the lens.
Although it is sharp but when I used it at 40mm and max aperture, it does not have a shallow dof even the subject was less than 1.5 meter away. Most of the background still very conspicuous.
I am thinking of getting the 75mm f1.8. Would like your advice if the dof will be similar to FF 85mm f1.8 lens which I am used to.

Bro. M4/3 is crop sensor. Expecting thin DOF with a 2.8 lens is a bit too much. If you want thin DOF look at the MF CV lenses f/0.95 or the panny 42.5/1.2.
Thanks Bro,
Just not used to the m4/3. Maybe I will go for the 75mm. hope it would be better for the shallow dof.

M4/3 is a 2x crop sensor so naturally it will be harder to get shallower DOF. This is also the same reason why you can never get shallow DOF with your iPhone or compact P&S cameras, their sensors are so small. You can think of it as a "crop" of an output from a larger sensor.
75mm f/1.8 to me is not comparable to FF 85mm f/1.8. Already the FOV is different, which means if you stand at the same spot, you will get different perspectives. What will be equivalent is 150mm (75mmx2) and I think f/3.6 thereabouts?
A more comparable lens will be 45mm f/1.8. You will get equivalent FOV but definitely not equivalent DOF (also f/3.6 probably).
Equipment limitations can be overcome though - lens max aperture is not the only factor in getting rid of BG - you can decrease subject distance to camera relative to background distance to camera.
Wonder if someone more technically competent can advise on how to convert equivalent apertures. Is it also 2x?

To answer kch076's question, the direct comparison to the FF 85mm f1.8 would be the voigtlander 42.5 f0.95.
To answer Edutilos, the aperture does not need to convert.
For example if you are using 45mm f1.8, the speed of the lens is still f1.8. Some photographers think of it as gaining 2x depth of field without compromising shutter speed. For example, when taking table shots during a wedding, you can shoot at f2 to have a shutter speed at f2, while having a depth of field of f4 for the table shot.

You can take a look at my reply on the E-M10 thread. Since the DOF equation is non linear and also depends on the sensor's circle of confusion, there is no easy rule of thumb to convert by adjusting focal length and aperture only.
Easiest way is to use a DOF calculate or app to compare.

I know, was referring to equivalent DOF.

Thanks Bro, this is quite helpful and you understand what I meant that I was quite disappointed with the DOF of the 12-40 f2,8. I will try out the 45 f1.8 and the 42.5 f0.95 as suggested by Halfwake, though I may not be used to manual focussing in this format.
bro, hmmm.. I'm not a very technically competent coming to camera-speak. edutilos and clicke are definitely more knowledgeable.
If its DOF aka background blurness u r looking for specifically, the best will be to go for the Voigtlander 42.5/0.95 , O75/1.8 or the O45/1.8.
however, I don't really believe in that a 2x crop factor implies that a f1.8 becomes f3.6 in FF equiv in terms of image results. A lot of factors goes into play, something even as simple as distance from subject matters.
that said, here's a shot using the 75/1.8 (plant at void deck la)
and this one below taken by the 12-40/2.8

just to share the following pic..
my E-M1 top plate was replaced with a new one when the rear dial became unresponsive..
came back in around 2 weeks.. was sceptical about the weather seal..
then it became unresponsive again..
i am really very unlucky with all the OM-Ds.. :cry:
E-M5 got thrashed and now this had to happen to my E-M1..

Cheer up bro ,
it's indeed unfortunate but thinking about it, at least the repairs were all paid for ? They gave u the top plate as a keepsake ? Lovely pic though.

you meant the dial is unresponsive again after fixing? I think you should ask for replacement cam, else it's would be almost a month without camera. Sounds similar to varf's problem.
