You take a picture from a flat subject, like a brick wall, head on (so the picture shows a rectangular pattern, not a trapezoid). Then you turn the camera upside down and take the same picture ...

The first and second shot show softness especially in the top left corner, compared to the top right which is at similar distance so should be equally well in or out of focus. This lens is not as ...

The third shot at the bottom left seems to show an effect that I see as a hint that maybe you shot through a (closed) window. That will certainly cause softness depending on the angle the light ...

When you reduce a 16MP image to about 2MP the signal of 8 pixels is averaged into a single pixel. That *is* a very strong form of noise reduction. And yes, I do realize that when you look at ...

I say that because especially in low contrast detail like the bird's feathers you either lose detail at ISO800 because of the needed noise reduction or you keep the detail but have quite a bit of ...

ISO 800 means goodbye to low contrast detail, especially in jpg and especially on a Panasonic camera. If the mechanical shutter was used that's another potential cause of a slight unsharpness... ...

That means software needs to correct for a *lot* of vignetting, even without the effect of IBIS into the mix.

The E-M5 does not have EFC. Whenever the mechanical shutter is open it starts recording the light. It does not have a way to clear the sensor readout while being exposed. The anti-shock on the ...

I understand EFC and use it all the time, even with the fastest option on the E-M5 II which drains the battery faster. I also understand the difficulty in synchronizing the speed of the EFC which ...

While both lenses are outstanding in terms of sharpness the 12-100 has significantly darker corners (wide open at the wide end), which is of course automatically compensated for by software, but ...

Assuming what you mean is on one row it is RGRGRGRGRG... and the row below it is GBGBGBGB... so the green dots are always diagonal to each other. (With RGBG and GRGB the green would form vertical ...

If you click on the picture there is an option to download the (full size) jpg. Noise galore there! There are no miracles. But when viewed on screen ("large" size) that noise is mostly averaged ...

I know the sample gallery we have is only from a pre-production model, but if it is more or less representative of the image quality we are going to get... what we are missing is precisely: :"The ...

In continuous focus mode focus is often adjusted back and forth in rapid succession. With many lenses you won't notice this much. But some lenses, like the 9-18, suffer from focus breathing which ...

You can capture wider scenes in a piecemeal fashion. Takes a bit of post-processing but it's a useful skill to learn as no matter how wide your lens is you are bound to encounter situations where ...

When reducing my 16MP images to around 2MP all my images taken with the 12-50 look very good. For 2MP images my copy of the 12-50 was excellent. For 16MP images, not so good except in the center... ...

At least it should have been an option for those wanting a better lens. At the time the E-M5 came out there was no really good standard zoom lens available. I tried some prime lenses to get sharp ...

Olympus 7-14 f/2.8, 12-40 f/2.8 and 40-150 f/2.8.

The 12-40 f/2.8 should have been a (premium) kit lens bundled with the E-M5 when it came out in 2012. The E-M5's reputation was hampered by the lacklustre 12-50 f/3.5-6.3 kit lens. It would have ...

Another reason to stay away from it and save up a bit more for a used 9-18 which will give better image quality, especially in the corners.
