Typically I turn my gx8 stabilisation off when I am photographing fast moving static subjects such as roller derby. I also turn it off for astrophotography.

A brief interrupt: Panasonics gx8 20mp sensor also has a strong magenta cast when boosting deep shadows. PS. Loving reading this thread, it's good to learn about the science tech.

My Panasonic had a habit of locking up with one particular sandisk card, which in theory should have been a perfect match.  Changed to Learn cards and bingo, perfect, no more lockups. So I would ...

It's not a lens problem. All my lenses do that under certain indoor lighting conditions.

Good point and  question Gary, but it may be worth considering this also:  as the 300mm f4 will focus so much faster. It may actually use less juice. Lots of research testing needed, someone please.

I think the answer is that it might be, but unless you have a 20mp sensor plus a High quality monitor and a premium raw converter plus good eyesight, it may be impossible to tell.

I agree and how's the stabilisation on the 40-150 😂

They are both very sharp at that focal length, what is the problem?

I own almost all of the expensive pro zooms, but only use them if I need a fast aperture or that extra bit of reach the 100-400 will give me, because the non pro lenses I have are very sharp and ...

I am very jealous, I have only ever seen a hummingbird hawkmoth twice in my life and certainly had no chance to photograph one. Excellent.

Thank you, it is much appreciated.

I use them all the time. A typical example... For Roller-Derby i a have c1 setup for a fast shutter speed using a High ISO and a small focus square. I have c2 setup for a slightly larger focus ...

Thank you jorginho.

Thank you I will do some more research, as this e-shutter readout speed is the main factor for me - and more focus accuracy at 800mm.

Trevor I am not near home so can't post images but this info might help. With the small tube (they come as a pair) i can fill the frame with a large butterfly or swing around and catch a bird 40 ...

And I can guess what c1, c2, and c3 mean 😂

Thank you, very good points.

Thank you Maria. Oh dear, someone convinced me to just keep the gx8 and wait, but now you have convinced me to get an em1-mk2. Oh dear, what to do ???

I thought I recalled someone here measuring it at around 1/20, except for in some pseudo video crop mode. I believe the gx8 is around 1/25.

On the dpr image comparison tool the detail that the gx8 extracts from the scene is only equalled by the gh5. Just look at the legibility of the small text. The image quality is amazing, it's speed ...
