On a photo in the Canon EOS 6D Mark II sample gallery sample gallery (2 comments in total)

Constantine e: how do you use the EF-S lens??

Mount it. and make sure to correct the heavy vignetting. But it seems (from a quick google - I don't own Canon FF or APS-C) it generally works. Use it in live view to prevent the mirror hitting the back element.

kobakokh: to be honest i saw this video and i think Canon 6D2 is very bad camera for landscape photography, especially in that contrast scenes. Very small DR, you can see at this video very easy. If owner will use, for example Nikon D850 (or D810), Pentax K-1 (its even cheaper then this plastic Canon 6D2), he will understand what is a really good camera for landscape photography. Ooh, forgotten, also Sony 7R2 or 7R3 is also great camera for it. Also, much better to use some wide fix lenses, for example, Zeiss 25mm, Sigma 50mm Art, i mean the lenses with very low chromatic aberrations which is very important for post processing.

kobakokh : Brandon van Son uses a (really beaten up) 6D for his daily work. He is a pro travel photographer.
Thomas Heaton uses a 5D mk4 - and he is a landscape photographer.
There are many more PRO landscape pohtographers that I came across in the past. So landscape is possible with Canon, even on a pro level ;)

Don't get me wrong: I also read the tests and the comments regarding 6DmkII and its bad sensor (even 80D has better DR), probably really a mistake by Canon in this spec-sheet- and clinical-test-driven world. But this isn't about DR of film. They still have a workable DR. Furthermore I don't own a single peace of Canon gear. I have some Nikon and Olympus cameras and lenses from film days, besides that 4/3 and micro 4/3. But I look at tests and even download RAWs when DPReview tests a new camera: I just can't see what you try to tell us here...

When I read comments like this (all Canon cameras have really bad DR and you get banding when processing raw files) I really wonder how it is possible that PROs using Canon managed to ever sell a single picture because nobody wants images with bad noise and banding... But probably most Canon PROs photographed with Velvia in the past which has a DR of 5 stops.
Most likely the difference between you and PROs is that they know how to deal with light and use proper exposure and filters (for the bright sky incidents) and don't see the need to pull up the darkest areas in a photo to 18% gray.

bruceofOz: Hi Guys...Where can we find out what lenses have been used for both the Oly and Pana comparison photos? Any info would be welcomed!

There is an (i) under each crop display - hover it and you can get the info.

bluevellet: Looks pretty similar to the GH5 (no surprise), maybe a tiny tad sharper. Not sure.

Pity there's no pixel shift comparison maybe because there is no RAW support?

And too bad DPR keeps using the Zuiko 45mm for their m43 test.

Tiny tad sharper comes from Oly 45mm f1.8 (GH5) vs Nictocron (G9). Makes it hard to compare mFT offerings.

Andrew2468: My 2p / 2cents worth...
The studio scene tool is more about lenses than sensors and electronics. How about some additional new tests aimed at the latter. E.g.
1. How resistant to electro-magnetic interference is the sensor/electronics. E.g. does the DR reduce if someone standing next to you is talking on their phone when you fire the shutter? And if you have to shoot near heavy electrical gear?
2. Temperature and humidity. E.g. is image quality the same shooting in the arctic as the tropics. How well does the sensor cope?
3. I think I read light hitting the sensor obliquely can be an issue. Can evenness be tested, preferably without a lens, e.g. direct light beams at the sensor in varying places and at varying angles and analyse the numbers.

Perhaps something like the above might reveal there are real-world differences between makes and models that we don't know about.

But there are solutions, e.g. you could buy one of those stickers available for your phone to protect you against microwaves. It will for sure improve your image quality! If you still think it's not up to your standard wrap your camera in tin foil but leave the front lens open - use wired mesh (e.g. metallic mosquito net) for that.

2) The sensor does well, only the IBIS will work worse. Mostly because YOU (the photographer) is shivering from the cold. But IQ in general will be much better as there is less radiation going on (more heat, more radiation) - and for that look at 1)

3) Those tests ARE done and for photographers that request ABSOLUTE image quality lens manufacturers came up with SHIFT/TILT lenses so that photogs can fine tune the angle the light hits the sensor.

Wow, great questions! Finally someone thinking instead of just trolling.
1) Absolutely! The Sonies aren't protected, in fact most cameras aren't protected. Look here, you can clearly see the interference:

And as you can see it's the Olympus that does best in that regard. I think they make great use of the wireless antenna, they measure the external microwave background and use the antenna to counter and erase (hope it's the correct term, I am no native English ;)) the waves.

On page 21, there is a listing for lenses compatibility for the 5 axis dual IS and 5 axis dual IS 2.

Panasonic promised a firmware update in 2017 for the "old" lenses (which did not arrived yet..)- but concomitant started releasing V2 of a few "old" lenses too, like the 12-35mm/F2.8II, 35-100mm/ 2.8II etc.

sijou: no official paper, but at around the time of the release (AFAIK it was together with the GH5) I watched some videos and especially PhotoJoseph [*] had some first-hand information from a Panasonic official (Sean Robinson) even with live-interviewing and that's where they mentioned it.

Jim Salvas: My experience with the Olympus hi-res files is that you get most of the advantage by processing the RAW file. Those 80mp files can take an extraordinary amount of sharpening and processing. Olympus also provides a single low-res frame with the RAW, which allows you to up-res it, layer it in Photoshop and use it to patch the moving elements. I'd imagine Panasonic's files will be the same.

otto k: The Olympus E-M1 mkII has the option for automatic motion compensation and also applies it to the RAW as well as the jpeg. The issue is that it doesn't always work 100% (e.g. fast moving cars) so having a separate non-hires raw/jpeg is great to fix those areas manually.
Also it looks like Panasonic applies some sort of motion fix as the usual artifacts aren't there - again not 100% accurate, fixable with the additional non-hires shots.

In reply to:

otto k: Somebody correct me, but at f/8 you are severely limited by diffraction (m43 sensor, 80MP). You should be under f/4. I know you can look at it with different criteria, but still...

No, f8 is just fine. Even at f9 you aren't "severely limited". Keep in mind that you do not need to resolve 80MP, it's enough to resolve 20mp.

They hoped to upgrade to Dual IS 2 compatibility, but in the end it wasn't possible (hardware limitation). Support for Dual IS 1 is there, in any case, which should be enough for most use cases, Dual IS 2 really comes into play at FL greater than 280mm.
But there are other benefits to the 12-35 and 35-100 version II like weather protection or step-less aperture.

In reply to:

sijou: Since the new versions of DFD on both GH5 and G9 (480fps vs the previous 240fps) focusing has improved, the question arises: will our "old" V1 lenses work fully on this new cameras or we have to throw them in the bin- or just use them on the old cameras...My guess is that the new V2 lenses received a faster controller to cope with the high speed and precise positioning of the af motors and the optics remained the same - but since Panasonic has released this document promising firmware update- it may be the case only of a new firmware update would be needed - which did not arrived yet.. But will that ever arrive? Or will we be forced to buy new lenses to benefit from the precise and fast AF and other improvement? Or let's ask differently: what will we loose using the old lenses with the G9 ?

AF system works with 240fps - camera side (partial sensor readouts) as well as lenses. And all recent lenses, even the cheap ones (12-60 f3.5-5,6, 100-300), work with those fast linear motors.

dpfan32: Remember what the price of the G7 was? The G9 price is simply ridiculous

G9 is a different line, they shifted.
G7 -> G80 (G9 is a different beast)
GX7 -> GX80 (GX8 is a different beast)
The issue here is that you can't see the G8 - well, Panny, thx, G8 is the G80 in some areas ;)

You also might just look at te features and compare it to G7 or its copetitors at Fuji/Sony/... How much would you pay for 20fps with AFC, 60fps AFS, 4K 60fps, High Res mode, 2 UHSII card slots, etc... And you would see that currently there isn't much to compare this to - Oly E-M1.II, Sony A9. Know more?

fft2000: Just for those complaining: AFAIK this is the first time in dpreview history that Raw development wasn't done with ACR (or similar) but in camera. You likely will see improved noise/sharpness doing development in Lightroom (Or ON1, DxO, ...) as Panny still seems to do more noise reduction than needed (On my G81 I dialed it down to -5 and still think it is too much). But still I find it impressive what the engine delivers - and that you can really fine-tune your jpegs in-camera.

Carey: Thx for your response. I viewed close to every gallery - but as it looks not closely enough because I never saw in-camera processed files.
And I always forget about new cameras not being supported. I use RawTherapee and it usually opens every file, even if it produces garbage ;) But with mFT I never had an issue.
Great work btw. - can't wait for more 200 f2.8 shots, I assume this is the perfect sport lens (e.g. soccer, basket ball,...).

Well, the biggest advantage is that you finally have a use for your 500TB RAID storage...

Thank for for the preliminary HR shots. Caught up well to Olympus. Unfortunately there seems to be no movement compensation - but could be added per Firmware update.
Was there a single frame saved together with the HR shot, just like Olympus? If not it will be impossible to fix those areas in post. I REALLY hoped for Panny do it like Pentax - store single frames and leave it to PP software to stitch the shots. AFAICS Rawtherapee does a fantastic job in that reagard!

Bram de Mooij: The size and price of this macro thing is the reason not to get rid of my MFT gear yet. Even my Nikon 105mm f2.8 FF lens looks comparable in size and is less expensive.

I am using an old Nikon 105 macro (get it around 300€) adapted on my Panny G81 and I like it.

That's close to 1:1 reproduction. Just a quick stack of 5 images, all OOC jpegs. Single images are taken with f4 at ISO 800, 1/100s. Processing RAW and fine-tuning the stacking will improve quality, but I currently lack time.

In reply to:

TN Args: So a Sigma Art 35 on a FF body would beat the GF45 for subject separation (DOF)? These lenses are basically reducing GFX users to having Micro Four Thirds-type subject separation, aren't they?

@shigzeo that special glass (asph/ED) is used to make lenses smaller. Without those you would need bigger and more normal lenses to get a similar degree of correction (aberrations and distortion).
