On article Panasonic G9 added to studio scene comparison (168 comments in total)

What a useless test chart. This cannot be compared to anything. Why did dpreview switch to the Leica 42.5mm f1.2 lens, where previously the olympus 45mm lens was used.
Now we cant compare within the system. If your going to switch lenses, you will need to reshoot all the other M43rds cameras with the same len.
Ideally it would be good to use the exact dame lens on all camera tests. I vote for buying an Adaptall 90mm f2.8 and shoot it on everything.

tedolf: A missed opportunity.

I was really hoping that Leica would make a m4/3 body that really was like the film CL, with an optical VF, three small f/1.7 manual focus lenses (14mm, 20mm and 42.5mm), 4/3 aspect fixed LCD, etc.

sort of a miniature M10.


Maybe not, when the GX9 comes out it maybe they will brand it or release a Leica labelled come.

Carey Rose, thank you. This is interesting.
One question, what is the longest shutter speed that can be used in high res mode?
In the Panasonic interviews they said 1 second leading to a maximum capture time of 10 seconds, due to the 2 second proccing time.
However, your last shot says 1.3 seconds!
Was this a mistake or can you use high res for really long shutter speeds.
Thank you.

The only feature on this camera that has me interested is the ifilm idea. Being able to pop out film backs to swap color and black and white is great. But would also allow the company, if successful to make various digital backs, with various sensors up to the size of 135 format.
That could be interesting. Have a dumb box to control shutter, pop on whatever lens mount, then pop on whatever sensor, even film. That would be a fun modular camera to have.

BasilG: Is it just me or is the order of pages all messed up? Conclusions in #6 at the moment (of a total of 13...).

No I agree the order is messed up. You can not title something "the final word" and put it on page 6.
Plus not all the other pages are indicated or marked as supplements or appendix.

John Koerner: Best DSLR on the market ... best possible image quality ... better than the Sony A7rII ... better AF & speed too ... but only gets an 89 compared to the Sony's 90?

Lame, illogical scoring ... an utter waste of time. DPR can't even get their sequences straight (conclusion is 6th instead of last).

Dpreview should just go back to the old way. Give everything a Gold award. If it sucked it got a silver, and if it was a pain to use or ate your cat it, then it would get a bronze.
As the numbers are meaningless anyway. I think thats was the best system.

Very impressed by the differences between the Df and the 850. The same lens is used, and set at same field the 850 pulls much better detail and reduce colour noise at high iso.
I guess 4 years in sensor life still does make a difference.

In reply to:

Joed700: I'm not sure if this is a good way to compare image quality among other things since they all used different lenses. Based on the RAW files data @ ISO 6400; f/5.6, here is what they used:

5DSr: ef 85mm f/1.8 USM
D810: 85mm f/1.4g
D850: 85mm f/1.8g
Sony: FE 55mm f/1.8 ZA

I fully agree. You can only compare within a manufacturer, for differences in the sensor.
Would be great if Dpreview used an adaptall 90mm f2.8 lens. Thus the exact same lens on each camera to make comments about sensors.

The dpreview article is actually wrong.
From google translate he said the following:
"In addition, from the customer base, Nikon's entire coverage of the crowd is very wide, from the primary, enthusiasts, senior to professional users, then this is the biggest advantage of Nikon, like Olympus, Sony, Fuji they can cover Just a small part of the real professional people to use their camera, has not yet seen. Their customer base is limited, it is in the development of products, even if it is retro version, it is only to meet some of these people's preferences, they can only do so to the extent. "

Which may or may not be more insulting. Either no real professionals use Olympus micro four thirds, sorry Kirk Tuck. Or interpreted as there is only a very small number of professionals using the products. Both however are wrong. But he did not say no professionals as dpreview claims.

kaister: Uhm... it's almost the same price as the 1.2 50mm nikkor, which performs better - I realize this might be a moot point for canon shooters but for those shooting Nikon or Sony with nikkor glass the sainsonic holds little appeal.

Yes that is the first thing that crossed my mind. The Nikon 50mm f1.2 manual lens can be purchased around $500 brand new and used on nikon cameras directly, and any other camera with an adapter, including canon cameras.
I don't see the cost savings or point of this lens.

No this is different.
Tracking and zoom are diferent things and so is this. This however does seem to take a lot of work. Here they are pinning objects in the scene, allowing to move selective objects in and out. Like your video just with selcting the railing or the lights only.

Just wow,
His bigest argument is that the android has too many choices and options. Thus Apple is better, because you are limited and stuck with one option.
Sorry even that is garbage as there are other camera options on iphone.
If you truely care about photography, you learn how to take photos, the tool you use if irrelevant.
This post makes me feel that Apple has finnaly lost control and is grasping to get market share. I will not be surprised now if lots of movie stars and athletes start saying how good Apple is. To me its a sign of the end.

A true soul hunter camera. The S7, should be marked with a mode to find your hidden inner demon. Both sides lady are exposed in full colour.

I think this article is a little over the top on the issue of sand. I bring my Oltmpus E3 to the beach with both 14-54mm and 50-200mm sealed lenses. I even carefully switch lenses there and for true test hand it over to the kids to shoot with, currently 9 and 6. No issues since 2008!
Maybe because its Olympus or maybe the author is just a little over the top on the issue of sand.
Or maybe the E3 really was hurricane proof?

Roland Karlsson: Why call it stretch? Why invent new words for already known things?

It is either variable length, macro focusing or helicoid. All perfectly fine names. The word stretch do not add anything to humanity, other than just confusion. And maybe also Fotodiox'es marketing department get happy.

BTW - stretch hints that you pull it out and push it in, like some kind of LensBaby fun adapter, that you probably also can tilt a bit. Is this the message they want to communicate?

They don't want to use the correct terms, like macro helicoid, because if they did you would find 50 better cheaper products. They need news headline and a new name so they are all you see in a search.
I have yet to get a product from them that has worked. My nikon to canon g adapter would not fit and needed filing. My pentacon 6 adapters from them were 1mm too long and will not focus to infinity. Much cheaper Chinese products to replace have worked without fail.

dash2k8: I want that flash! So small yet so powerful, why hasn't any of the major brands made something like this yet? Canon, Nikon, Sony et al., are you guys seeing this!?

I dont think that flash comes from the camera. Rather the light emitted as your soul is being ripped out of your body.
Also why the images are so dark, the flash sync can't match the soul ripping speed.

Link | Posted on Jul 1, 2017 at 12:53 UTC

Yep using excellent Nikon glass with adapters on the Canon cameras cause slow manual focus. Those Canon cameras are terrible. Time to switch to other brands.
Seriouly dpreview, this is junk. If Sony is slow with Sony glass than fine. But using a non intended lens with a third party adapter is ridiculous. People should be glad the option even exists.

SmilerGrogan: There is a much simple answer to this problem. Shoot the camera like your readers would—use the manufacturers autofocus system for the test scene. If the results are sharp; GOLD! If the images are soft; that's the way the cookie crumbles and better luck next time.
Retesting a camera isn't fair to you or the readers. It wastes your valuable time and gives readers a false sense of what the cameras are capable of. None of us have all day to focus one photo and neither do you.

@Rishi, I agree but to be honest you do leave cameras at default settings. Not kicking back over handed NR, or sharpening. So the is variables not addressed.
I do like the green curve red curve conformation. That should save time in future an you could see if other cameras are correct.
