Certainly focus stacking would often be preferable (and quite easy now), but it also has limitations. Mark

If you can live with diffraction effects there is an advantage for m4/3 in that most lenses go to f22 whereas few FF lenses offer the equivalent f44.

I think the 4/3 9-18 supports CDAF whereas the 11-22 does not, so the focus will be much better than the 11-22 though still not up to m4/3 standard. Mark

I find it quite acceptable. I don't have any issues with the field sequential design. Of course a bigger view would be nice, but not at the expense of a larger body. Mark

Optical sensors are rather different to CPUs.  Because light is quantized the best we can do is count every photon, there is no finer division possible. As I understand it we are already recording ...

At best you would get one electron per incoming photon, I believe the best current sensors get around 0.8. In this respect sensors are within half a stop of perfect. I think noise performance is ...

According to the manual for my GX9, preview does work in A mode (as well as P,S,M, Ia, Ia+). Mark

Everything (photos+video) on this blog entry was transferred from my GX9 to my phone using the Panasonic Image app, then sent via bluetooth to my friend's laptop and posted to her blog (OK, her ...

Yes, my GX9 can do it (not 4K though as far as I recall). Mark

While there may be sensor improvements in areas like readout speed or the fabled global shutter, I can't see substantial improvement in low light performance. Existing sensors are already quite ...

For Panasonic the 12-60 f3.5/5.6 and f2.8/4 are both weather resistant. I believe the 100-400 is also, but don't know about the others.

I believe the crop factor on the G85 and GX85 for 4K is about 1.1, rather less than the 1.25 on the GX9. Mark

I have not used the EM10 mk2, but have been impressed with the CAF on my GX9 (using a Panasonic 45-150 f4/5.6 lens). I suspect others have been mostly comparing SAF. Mark

If you need the weather sealing, then you probably don't want to change lenses. I think this will make a zoom often the preferred option in damp conditions.

Note that non CDAF compatible lenses will also AF on most m4/3 bodies albeit quite slowly. For example, my 11-22 will AF on a GX1, but it typically takes around 1 second. The old 40-150 f3.5/4.5 ...

I disagree, I am rather impressed with my Panasonic 45-150 f4/5.6. Mark Thornton

Posting to Instagram/Facebook/etc isn't the sole goal, just the first step. In some circumstances a camera has a clear advantage even for web size images - e.g. where a lens significantly ...

With the GX9 and Panasonic App it can be done quite quickly, albeit slightly more fiddly than with just a phone.
