The real evidence is in the photos. If you can't try it, have a look on some bird sites. The ones I refer to are on a closed group Facebook page so I can't link it but there are plenty or images...

There's a very high chance Sigma will quickly produce their 40mm monster in L mount.  No adaptor needed!  You are right that it will be longer.  On the other hand, with a really high quality, ...

I don't really care what "most" agree about if that refers to people who don't use something. Seeing is believing and I have seen. Either way, if you are writing off a camera you haven't seen...

Did you not read my post above? Tracking swallows in flight is sensational continuous auto-focus!

Others disagree with you about video auto-focus. It seems Canon's dual pixel auto-focus works...

Focus tracking of the EM1/2 is good enough that my friend gets perfect photos of swallows flying. Tiny, fast, erratic birds that challenge any focus system. No camera is perfect but to knock an...

"pro photo 2011": Olympus have used phase detect on the EM1 models for quite a few years now. If you shoot wildlife, their instant focus acquisition is mind-boggling. You would, surely, expect a...

I doubt many people interested in buying those cameras will be reading this because the article is about a completely different type of camera. My tests involved a wide range of scenarios, both...

"entoman" - I'm glad we gave you a laugh! Seriously though, I did have both cameras at the same time and did exactly what you said. That is the foundation of my comments above. The underlying...

Sigma have promised just such an adaptor and I believe someone else already makes one. I actually already use EF lenses on my L mount camera via an M mount adaptor but it's manual focus only and...

Denimage, it sounds like there was something wrong with your Panasonic. Mine focussed near enough to instantaneously in most situations. Place focus frame over subject, touch shutter button, bang...

Denimage - I doubt that there is anything wrong with my RX10/4. It's fine in easier conditions. Then again, so was the FZ1000! I think PDAF, as things stand, can be better than DFD if tracking...

Thanks for posting those.  It seems that the possibilities are good (lovely lens).  However, despite the photos being really quite nice, it does look like exposure and even colour is an issue (I ...

I went from a Panasonic FZ1000 to a Sony RX10/4 as my "bush camera". One strong requirement of the camera I take to work with me is that it has to be quick and accurate at focussing on small...

If anything, it will be priced to compete with the Sony A9. Probably not as cheap though.

It really didn't read like that...

When I read the title, I thought this could be a genuinely interesting subject.  However, the one photo posted tells me a tiny bit about lens quality and very little that is helpful.  It's not ...

Great choice - and well explained!

For some of us the compact, fiddle-free fixed screen is a definite bonus. It makes the camera better.

The term "mirrorless" is almost as annoying as applying the term "full frame" to only one size of full frame!  Nevertheless, it has a practical consideration in terms of lens design because it ...

I was.  It's exactly the same scenario, with different sensor sizes using a different mount.
