Nikon announces full-frame mirrorless camera

I'm hoping they come out with a mirrorless camera with a APS-C sensor, same viewfinder as the Z-Twins and similar controls as the Z but with a F lens mount and without the hump.

I was thinking along similar lines...dx, integral f mount adapter, dials like a Df, and cinematography friendly

Ken, thanks for the update.

What approach did you use for the MF?

Also, was there an AI tab on the adapter for the Z?

Thanks.

I was using peaking - there wasn’t enough time to figure out magnification. No AI tab, it uses stop down metering.

Thanks for the update.

Too bad they've abandoned the old AI tab. There's a heck of a market out there they could tap into. Not on the Z-Twins but the next step down, folks who don't use them to make money.

Keep us in the loop as to how you progress on the move.

Will do! Really, there’s no need for AI tabs on these - everything is done at the taking aperture.

In practice do you find focusing at f5.6 vs f1.8 an issue?

Thanks.

Do you mean with AF lenses? I’m not sure that’s accurate, there’s been a lot of discussion about how the AF works. I didn’t think to look at the business end while doing an AF run, I kinda wish I had.

With MF lenses on the adapter, you focus at the taking aperture.

Or am I misunderstanding what you’re asking?

Not you, it's me,didn't give you enough to background.

I'm thinking about old MF AI glass. I've experienced it when I had a XE-2 and a 85/1.8 old lens. Focusing wide open I could nail it but when I was shooting at f8 I had troubles finding it.

AF would avoid the problem all together, but that's all new glass. Not using it to earn money that's something I'd like to avoid.

Focusing At Narrow Apertures

Focusing At Narrow Apertures

Nikon, and other DSLR centric brands, do not care about people who prefer to use manual focusing. This is one reason why I abandoned Nikon in 2011-12. After several attempts with three different Nikon cameras I could not achieve reliable results with the green dot method.

Obviously, I am not familiar with all of the new Nikon platform's focusing aids. For all I know, Nikon decided to implement powerful focusing lens aids for non-AF lenses.

In general, I found the best alternative for focusing with narrower apertures is focus peaking. There are two approaches.
  • You simply make sure the intended focus point displays intense peaking.
  • Move the focus region and temporarily crop (zoom) the EVF display to select the focus point. Then maximized the peaking.
In my case it took a while to learn how to read a display with focus peaking. It is confusing to observe large regions with peaking when DOF is wide. Field curvature can add to the confusion. Regions and objects with more contrast can have more intense peaking than a lower contrast objects that happen to be at the focus point. With wide angle lenses these problems can be disorienting. That's the bad news. The good news is if the intended region or subject displays heavy peaking, it will be reasonably sharp in the rendered image. I realize perceived sharpness is only maximized at the true, but unknown, focus point. The issue is whether or not the MTF50 degrades significantly (the actual lens MTF50 is inferior to the total systems' MTF50) when changes in peaking are not able to differentiate the intended focus point. It just may not be not practical to optimize focus for non-AF lenses with the tools at hand. This doesn't mean acceptable focus is impossible

The second method attempts to minimize these problems by cropping the display. This usually makes maximizing the peaking intensity more selective. But it is slower unless the camera supports some sort of picture-in-picture display mode. I use a mirrorless camera with an OVF finder than can display a PIP, EVF, zoomed focus region. I primarily use focus peaking but occasionally use a simulated, split-screen display. I use different zoom levels for different circumstances.

There are some other variables that can help with focus peaking. Reducing peaking sensitivity could increase selectivity. Different peaking color options might work better for different people. For raw-file users, experimenting with in-camera JPEG rendering parameters could help too.

Low light reduces the effectiveness of all focusing methods. Similarly, scenes with low native contrast are also a challenge. In very low light EVFs are affected by low S/N.

Focusing wide open is an entirely different matter.
 
In addition I would also add that movement (camera or subject) reduces the effectiveness of focus peaking too.

That's interesting …. I use the focus peaking on my two Sony cameras to track moving horses .

It doesn`t always hit but that's mostly at or near infinity otherwise I`m happy with its performance.

So, will Nikon sell also S to Z adapter? Haven’t seen it mentioned. I think they should :rolleyes:

Size of Lenses designed so far for Z Nikon unlike rumored Canon RF 35mm 1.8 which is very small ,suggest thick sensor stack , perhaps Canon sensor will be better suited for adapting rangefinder lenses any thoughts?

Why does the size of the Z lenses suggest a thick sensor stack?
 
The lens options for that canon blow the Nikon ones out of the water. 28-70mm f2L and a 50mm F1.2L that's probably 1/2 the size of the 58mm noct with AF...
