For m43 system owners this wide fast lens could be a terrific addition for shooting astro landscape.
... I just may have to get one!

buratino: As an MFT user, I have learned hard way that any F11-equivalent lens is pathetic crap. This opinion cannot be denied, it's well-supported here.

May I conclude then that a true F11 lens is pathetic crap? or equivalent to it?

So how good is the Hubble regarding Birds in Flight ?

Adrian Harris: Are written reports and test extinct on DpReview now?
Shame.

As the original OP, I apologise for using an abbreviated comment.

I meant it as 'what a shame', and not as some may have thought 'shame on you'.
The danger of using txt eh!

MikeRan: Looking at how poorly the thermal management is on this camera I’m starting to think the engineers didn’t intend this camera to support 8K. But the processor was designed to do it (with associated power consumption) for future applications and the marketing department insisted that the capability be included at the 11th hour and with no time for the engineering team to go back and rework the heat sinking.

There really is no other explanation as I don’t believe the Canon mechanical engineers are so negligent.

@Adrian Harris Are you aware the R5 has the current industry leading IBIS system inside?
No I wasn't. How will that work if the sensor is stuck to the backplate with this heat pad?

Sorry, I assumed the pipes were liquid filled.

Any in camera stabilisation would prevent a mod of this nature from being possible. I believe that the Olympus em1x has some type of internal water cooling.

Never mind squabbling over the tech specs or image quality.
The big question is: is it available in pink ;-)

The new company has just informed me that they have extended my camera and lens warranty.

On article DPReview TV: Understanding diffraction (115 comments in total)
In reply to:

grasscatcher: Ok, I need a camera with built-in focus-stacking coupled with a TOF sensor (or better yet, LIDAR).

I've tried Panasonic's in-camera focus-stacking, but it leaves a lot to be desired. The clunky interface takes a while to implement, and I get better results just using small aperture and associated diffraction. They really need to work on this.

I don't know which Panasonic camera you tried for auto focus bracketing, but even my old gx8 which only uses highly compressed 4k video can turn out really impressive results with good stacking software.
So the g9 which shoots much improved 6k should be capable of turning out stunning results!
But I moved to the Olympus em1-mk2 (before the g9 was launched) and it it shoots ful resolution RAW & jpg brackets with as fine or as coarse a step as required and you can program it up 999 shits.
Results are amazing. What's not to like :-)

What a shame it's a TV article, I would love to have known how the comparison went.
Reading reports is quicker and a calming experience. Plus I can also listen to radio whilst studying the tests.
I realise you will need to make videos to suit certain factions, but please don't ignore your forum 'readers'.

CekariYH: Looks like a great Travel/Walk around Zoom for Olympus owners!

Are there any other brands close to this zoom range and aperture throughout the zoom range?

Nice images Carey.

They're smaller than 12mm. Decide FF lenses by 2 to get equivalent focal length.

Pavel Muller: just one comment: Why?

Friends of mine who have tried this - of whom one was tutored by Brendan Barry - have become quite addicted. One doesn't even use photo paper anymore, he coats slate with some home made mixture and projects the image directly onto that. The results are a piece of art.

MHshooter: Focus sensitivity (ultra-shallow DOF) means probably using an X-Y rail for positioning of the camera, plus a tripod and head that affords easy positioning of the rail. Or, a dedicated macro set-up. Using a copy stand by itself would be difficult, the motion being too crude for such magnification. This is in the realm of low-power microscopy.

@MHshooer, a close friend of mine who uses the Canon 5x lens in his 50mp camera produces outstanding live insect in the wild images without using any of the fancy equipment anymore, he just puts a camera on burst and rocks back and forth on a trigger stick. Then stacks all the good captures.
Unfortunately when trying the same, I haven't managed the same success as he achieves - even though I use a lot less magnification!

BrentSchumer: It looks like this lens makes the Panny 100-400mm obsolete: https://mirrorlesscomparison.com/micro-four-thirds-lenses/olympus-100-400mm-vs-panasonic-100-400mm/

I agree, Dual IS should make things better. But after 4 years if testing with the PL100-400 on a GX8 I can assure you that it softens the image slightly. .. And is the reason I bought an em1-mk2, which allows single Stabilisation.

Dual is seems to work fine for my shorter focal length lenses.
