Just a reminder to everyone on this site. Nikon has NOT said what it is bringing out. I would wait until the OFFICIAL announcement later this month.

Yes, they may throw a curve and announce a Z1 that will use the anticipated 61 mpx. sensor they have been playing around with. It would become the new standard for Pro Photographers and compete with Sony's top model which uses a 61 mpx. sensor.

I doubt any adapter out there reduces IQ...unless it has a piece of glass in it.

I still use my grandad's Nikon lenses....four of them...and they perform pretty well...on my Sony.

Sidebar:

I am awaiting an adapter from Vizelex which does incorporate a CP filter inside the adapter.
Just something fun to play with...and get some water shots...take the edge off reflections and such.

This way I can have both...with or without CP...on all four lenses...no step up rings needed.

They make it for everyone except Nikon (I just looked)...but I expect it is coming.

If your AF-capable lens no longer can autofocus with the adapter, that might be a problem to some owners.

I use three F-mount lenses on my Z bodies (35, 50, 85, all newest 1.8) — in the studio and in the field. They work great and produce images that are, as far as I can see, not degraded at all. The FTZ adapter has no optics — it's basically a "filler" to put the rear element of the F-mount lens in the correct place for focusing (and to connect autofocus, exposure, etc., with compatible lenses).

Nikon just announced that a new camera the Zfc, based on the very successful FM2 body and the Z50, will accept all Nikon lenses. It appears to be like the Nikon Df was for the SLR cameras. It was announced yesterday at the PetaPixel site.

I have seen no change in images. There is no glass in the adapter; it is just a spacer. However it adds weight and bulk.

Canisdirus

Not sure what you mean.

Think the CPL can do that?

Or do you mean...the adapter itself? I get that part...but as all my Nikon glass is manual.

Just an option...I like options.

CHG_CANON Loc: the Windy City

I mean the adapter, something that for-sure disables AF for those lenses dependent on the camera for a focus motor. Some of the initial 3rd party lenses had problems too, some I don't think could be resolved via updates. But the optics, agreed, no glass, no changes.

Canisdirus

Sure...I gotcha now...and agree.

Not for everyone...meaning not a primary adapter...that I already have.

This would really be for the manual lenses.

Another option...and they throw in a capable CPL in with it...for $109...hard to resist.

I am not having any image quality issues using my F mount lenses on my Z9. Most of the F mount lenses I use are macro or long tele lenses.

The only "issue" is that to use them is that you need to add the adapter.

I made the mistake of believing (not knowledge) that there would be a degradation using the FTZ adaptor when I switched to Zs from DSLRs. Boy was I wrong. I sold all but one of my F mount lenses and bought new lenses. I wish I had acted with more experience. F mount lenses are fine in the Z cameras with the FTZ adaptor.

The F-mount glass has been with us forever. Is the Z-mount (especially S line) better? Maybe/probably. However, in my case (enthusiast), given the difference in cost between used F Glass and the Z Glass, I think that I'll get more bang for my buck if I invest in myself by taking workshops with professionals than if I obsess over whether I've gotten the best lenses.

keywest305 Loc: Baltimore Md.

I had the d850 and sold for the Z9. I have one Z lens the 24-70. I also have 6 F-mount lenses I use on my Z9. I see no difference in the two mounts as far as speed or focus or image quality. If is is there you better get some type of never yo measure it because by eye at least my eye I can NOT see

You should not lose any performance inherent in the lens. You may even get better results, because mirrorless cameras focus using focus points embedded in the sensor, not with a mirror and a separate focus sensor that can get out of alignment.

You might reach the optical limits of a lens on a high megapixel count mirrorless camera, meaning that a newer, higher resolution sensor could reveal design limitations or manufacturing flaws in the older glass.

If I still used Nikons or Canons, I'd definitely buy their adapter and test my old glass before deciding to replace any of it. For a "daily driver" lens such as a 35-70 f/2.8 zoom, I might want a new mirrorless lens, but for seldom-used glass, I would probably just use the adapter.

If you have a few lenses you use more often than others, test those first. But test them all, to see what you think.

Wide angles are likely to be a bit better with new, native, mirrorless glass. That's due to the physics of lens design for a shorter flange-to-sensor distance in mirrorless bodies. There's less light bending involved.

Weight and balance may also be a factor for some people. However, full frame glass is full frame glass, and moving from dSLR to mirrorless won't save a huge amount of weight across an entire kit, if you have 4 – 5 lenses in it. To save weight, you would need a Micro 4/3 system with the equivalent field of view lenses of half the focal lengths.
