semorg: Sometimes you need to get lucky and Nikon got very lucky, I think.

Most likely Nikon's product managers planned this entry-level full frame before the pandemic. Not sure how they were looking at their product differentiation strategy a year ago. Now with the economic slowdown, they have a the best priced entry level full frame mirrorless camera. Not sure if it'll be enough or not, but they're offering a very compelling kit for anyone who is looking to upgrade to the mirrorless market.

Those buyers looking to move into the mirrorless system. Probably upgrading from a mobile phone or maybe from a DSLR kit system (with little lens investment) will definitely have to consider the Z5 as an option.

Even more so, with the current and future economic situation, the Z5 might just sway new buyers into Nikon who might have considered Sony, Fuji or possibly Canon.

Well played, Nikon!

In my country

A73's street price is same as Z5;
spec-wise, it seems A73 could be slightly better than Z5 (higher fps / 4K / battery).

And Sony has a few cheap but high quality lenses (85 1.8, 55 1.8 or even 35 1.8 (slightly overpriced)

I think most will think it is a true DSLR/ML hybrid if it comes with IBIS

demaio: R.I.P Sony :)

With competition, Sony will produce better and cheaper A7!

ShaiKhulud: Let's be sceptical for a second:

>20fps continuous shooting (silent shutter)
Canon is not using stacked CMOS (and Sony are not selling them), so I expect this mode to be pure marketing with heavy rolling shutter.
>8K video capture*
*Something tells me that it will be like 30 seconds with huge crop or something like that.

There are no miracles when your sensor fab is years beyound Sony and Samsung, but I'm curious to see how the camera will preform on a mechanical shutter (and what real FPS with proper AF and metering will be). Also everything will be defined by the price point.

But it's nice to see that Canon is finally entering 2020.

Also it will be nice to hear about the battery life, the weakest point of the entire R lineup.

8K is 7680 x 4320 right?
that's 33M already
so Canon cannot crop the image < 33M.....

seloo: Nikon seems to have given up on pro DSLR market.

For professional, they should be happy with their D5?
Professional should knows D5 or even earlier generations are more than good enough

At this price; is it really attractive for existing Nikon Users?
If you already own D5 => what's the reason to upgrade to D6?
If you don't already any Nikon equipments => Canon or Sony seem offering better package at similiar or cheaper price?

For existing D5 users => why don't you use the money to get Sony A9 + some Sony lenses as 2nd system?

What have you done Canon?
You mean there is no need to buy A7r for resolution, A7s for video, A9 for 20fps?
It's all-in-one in the R5 package?

and with all the f/1.2 prime lenses, f/2.8 Trios, as even f/2 zoom lens already available?
and there will be more lenses in 2020 like 100-500mm , TC?

My god....

In reply to:

GrapeJam: I thought the advantage in wider mount is that smaller and cheaper lenses could be made easier but so far the Z mount lenses have mostly overpriced and oversized.

Sony's one is lighter, shorter and cheaper

https://www.dpreview.com/products/compare/side-by-side?products=sony_fe_85_1p8&products=nikon_z_85_1p8_s

optically, Sony's one is good; but we do not know if Nikon's one is better

AF - sony's dual linear motor is probably faster than Nikokn's stepper motor......

In reply to:

Anulu: It's heavier, bigger and $200 more expensive than Sony's stellar 85 1.8, and it has an outdated stepper motor instead of Sony's dual linear motor, no programmable button either.
If it won't be better than mediocre Z lenses so far, than it's not a good deal at all for that price.

@misspiggy01
Sony 85 f/1.8 is an outstanding lens

giving it a G or GM label won't help optically

In reply to:

pentaust: Nikon making no noise, improved eye AF via firmware, and rolling out their size reduced, moderately priced lenses for the Z mount (as opposed to Canon huge expensive RF lenses). Next will come the Z 20mm prime. It's all good so far.

Can I say Sony has better offerings at the moment?

cheaper f/1.8 lenses and body; better features....

DavidNJ100: People have already commented on the storage. I'm surprised you can't hang an SSD drive off a USB-C 3.1 gen 2 port or store 10-bit video faster than 100Mbps.

But the questions:

1) Which lenses can resolve 265 dpi? A medium format is one thing, but this is still a 35mm frame.

2) Why does it have old communications standards? Bluetooth 4.1? 801.ac? Should have been BT 5.1 and 801.ax (WiFi6). This is supposed to be a leading, high-end camera for multiple years.

There already 1T sd card and I am sure 2T is coming
why SSD?

the recently release GM lenses can resolve 61MP

802.11ax is not mainstream at all, router choices are limited and I dont think you will notice any real world difference

similar case to BT, 4.0 provides low power connection, you won't need the speed of 5.0 as the connection speed is not relevant here
images are transferred using wifi, BT is only used for the connection

goshigoo: It is a good lens, the only thing is not right is that Panasonic is trying to sell it as if it is a 20-50mm f/1.7 FF lens, but in fact, it is a 20-50 f/3.4

This will be a great addition to most m43 users if this lens is priced at 1000 USD

Anyway, it is ok
I have some friends who couldn't get into college.

Their behaviour are the same, because they really don't understand more advanced stuffs as they are too difficult to understand for them

I totally agree focus length is a lens thing
the point is using m43 require a different lens (different focal length) in order to match the POV
which in turn impacts f number if the primary glass is unchanged

primary glass determines the amount of light, which impact SNR
in my previous example I used the same primary glass, I.e. 20mm glass to build a 40mm focal length lens for m43 or 80mm lens for FF
obviously the primary lens is 20mm in both case, the amount of light is the same
but it yield different f number of each lens

I think the above is too difficult to you
as I mentioned, all you understand is step 1, I.e., f number = focal length / diameter of the primary lens
which is not related to sensor.....and you just keep repeating the same thing over and over again without expanding the scope.....

to take a photo with same POV
one need FF @ 80mm or m43 @ 40mm
right?

If you are comparing
FF @ 40mm vs m43 @ 40mm
It pointless

From the above example, you can see both lenses use the same primary glass, the cost is the same (in reality, the cost is different due to lens design)

However, Panasonic/Olympus want you to believe the cost of a 40mm f/2 lens on m43 is the same as 80mm f/2 lens on FF

the former m43 lens requires a glass of 20mm in diameter, while the FF lens requires a glass with 40mm in diameter

obviously, in reality, the cost of a 40mm glass is higher.....anyway, if you still do not understand the equivalency, I suggest you keep quiet and stop embarrassing yourselves

This will be a great addition to most m43 users if this lens is priced at 1000 USD

e.g. I have a fine glass with 20mm diameter
I can use it to make a focal length of 40mm lens ok m43
which gives a 40mm f/2 lens

If use the same glass on a FF system to take a same photo
I will need to make a 80mm lens
and the FF lens will have f/4 F number

that's what I wanted to point out
you guys can only thing 1 step at a time
I feel sorry for you

Photomino
It is related when comparing different format
because focal length changes for different sensor size
focal length affects f number

I.e. sensor size does impact f number in actual usage
you guys can only think 1 step only

I really don't think we can continue to discuss anything further...

Well.... f/1.7 is f/1.7 right ?

“Light/unit-area is meaningless. Light/unit-image is meaningful.”
This is exactly what I wanted to point out, most m43 users do not understand this

They thought light/unit-area, which is indicated via f number, matters
Which is totally wrong.
