ND64

This cheap lens discontinued two decades ago, a lens that even Ken put that in Nikon 10 worst lenses list! I put this on D7500, an almost 6k DX sensor, equivalent to 8k FF sensor, and resolution was pretty good. Sure you find many optical shortcomings in these things, but thats not all because they are old! They're designed for film, which has a slight curve, not for perfectly flat digital sensors, so corners are softer that what they looked in 1980. AND they're designed to be compact, suitable for FM2 style cameras. when you prioritize the size, you have to make compromise in optics.

lol

I'm pretty sure %99 of Nikon lenses out there outresolve 8 megapixel ?

If the adapter works flawlessly, they don't have to be in a "rush hour" in lens making. They are ready to release a ridiculously compact 500mm f/5.6 for the F mount. I bet they have already made its AF motor mirrorless-compatible. This is also true about Canon (they even want to release a EF mirrorless, which won't have the lack of lens issue at all). Besides, unlike Sony, Nikon and Canon and Sigma, have full control on the whole glass process. Though the capacity is not very stretchable, they been doin this business from A to Z, for decades. So if they really want to deliver a dozen new lenses in a relatively short time, they can. Don't expect Canikon accepting help from third parties as Sony did. That's embarrassing for these two big guys that calling themselves Optics company!

I was thinking about the complexity of our visual system that recognizes such small differentiations without any chart.

9 of them wil be Sigma Art. IF they can reverse engineer the Z.

This huge mount begs for a Cine lens line up.. Nikon won't spend money on that.. hope Samyang and Zeiss do it.

A square sensor costs a lot more.. we cant expect that from a trillion dollar company .. you know ?

They're so "humble" that intimidate reviewers https://petapixel.com/2018/08/01/my-drama-with-hasselblad-bullying-and-their-latest-comparisons/

Its only "assumed" for trolls. For photographers, its real. And there is no photographic "loss" in high ISO. Actually, D850 noise has slightly higher quality. According to lack of knowledge about Nikon advantages even among its loyal customers. According to their almost invisibility in social media. Oh you needed a copy of circuit design to evaluate! Well, they can't give it to you ? Or possibly not.... https://petapixel.com/2017/03/22/sony-keeps-best-sensors-cameras/ Oh certainly yes. Sony semi is way larger than Sony Imaging, and they don't say No to their high-volume-ordering partner in favor of their imaging division. Bussines facts don't care about your feelings.

With ISO 64 you can expose for an extra 2/3 of a stop without clipping highlights. Thats "real" benefit. If they had stock, they knew Sony Semiconductor is completely independent from Sony Imaging, and has strategic relationship with Nikon. Funny thing is Nikon's marketing is the worst in the entire camera/optics industry. They let Dave to visit their not-visited-before R&D rooms, but what Dave wrote is just his reaction to what he experienced. Simple as that.

Read noise at ISO 6400: A7R3> 1.05e D850> 1.2e You can't see this difference in images.

D850 pixel stores 10,000 more electrons than A7R3 pixel. So ISO 64 is not just a gimmick number that anybody can add to the spec list. Its indication of a state of the art read out circuit that is capable of handling such a massive amount of electrons. Also, Sony's advantage is not their fab devices and tools (they're far behind Samsung, TSMS, GloFo in nod size anyway), their advantage is their huge asset of IP. AND some of those IPs are bought from Nikon, like PDAF and some Exmor goodies.

Well, TowerJazz has several fabs.. if they can make sensors for Panasonic, they certainly can supply Nikon, which orders in much higher volume.

NR sources usually report numbers a bit higher or lower than what it actually is, mostly because they have early access to technical spec list, rather than marketing materials. Total number of pixels is not the "effective" pixels. However, I think at least one of these two sensors is going to be made by TowerJazz.

They said they cancelled it because they were not profitable as they expected at that price range. Even with your logic, stacked sensors are the bottleneck, since there is a processor AND a DRAM right behind them! Give customers a 18-50mm lens and see what happens in exif data of publicly posted images.

Now I understand why Nikon cancelled the DL. If you can't make a modern premium compact and yet keep it under $1000, you better forget it.

Thanks a lot bro

This is the result of having direct communication with your customers (Japanese should take note), yes its bulky, but in this case bulk is not necessarily a negative thing for me. With this developments in stabilizer industry I bet camera makers will ditch IBIS eventually. Its costly complicated mechanical thing that also exacerbates the heat issues.

OR they can deliver BOTH solutions, a Z mount Df style mirrorless, AND a D750 successor without mirror. And see which works better in long term. But lets face the fact. The problem legacy lens owners have is not really about mount compatibility. The problem is the AF motor in their lenses. All mirrorless system use CD as main AF or complementary AF to PD, and you know DSLR lenses suck in CD. They are designed in a way to move heavy glasses in few but big steps, not doing many but small back and forth movements.

Canon and Nikon have legacy advantage, Olympus/Panasonic have advantage of a well established and very well supported mount, Sony has advantage in sensor tech and huge IP assets in that field. What's gonna be Samsung advantage? Higher framerate? Thats far from enough.

Top dogs in DR has only 12 stop if you count the "useable" ones. So for today's sensor tech, anything beyond 14bit is just wasting the storage space. If they could manage to reach 15 stop or something, then we talk about 16bit, but that sensor should have the most noise-free pixel ever invented to achieve that. http://www.photonstophotos.net/Charts/PDR.htm#Hasselblad X1D-50c,Nikon D850

What's special about medium format color and why you think its not achievable by 14bit raw?

And you need that for what?

Hope they both keep their mounts. I don't have any Leica lens to put on a short flange mount. I just need my AF lenses work flawlessly with the upcoming mirrorless. Reserve compactness obsession for DX format.
