Are you saying then to look at a dark scene, nighttime, dark shade, whatever in 2.8 and then change the aperture to maybe 5.6 or 8 to actually take the photo because the scene is brighter at 2.8? I am not arguing but trying to understand what you are telling us.

Yes, that is what I am saying - but the brighter VF only applies to a DSLR with optical VF vs a mirrorless. The brighter optical VF would allow seeing the composition better in lower light - and help the AF. BTW, The auto diaphram of the lens stops it down to the taking aperture automatically at the moment of the exposure.

If I am understanding you correctly then, the cameras the OP listed would not be able to make use of the 2.8 lens for the benefits you suggest?

They ARE AF DSLR's with optical VF's aren't they ! ? - that is what I see .

My understanding is that mirrorless cameras do what you are saying but not DSLR's. I have not noticed my D800 doing that.

I think I am now understanding your "understanding" .......but the complete explanation here could be very long and better served in a separate posting or visiting google. Suffice it to say simply that a mirrorless will control the brightness of the EVF according to the f-stop/shutter speed/ISO exposure selected and with a DSLR with optical VF - the brightness is controlled by the maximum aperture of the lens. BOTH type cameras will use the maximum aperture of the lens to focus with and the brighter max aperture will help the AF to focus faster and more accurately for a given ambient light level.

While the Nikon covers more focal length range, the Tokina goes to f/2.8. So the question to you is, which is more important, low light use or zoom range?

Tell me about this lens (Tokaina 11-20mm). What are your experiences shooting with it? Any pro /cons you will like to share?
I am thinking of getting this one.

Since I mentioned this lens, i assume you are directing the question to me (it helps in these situations to hit <quote reply>). Unfortunately, my intended use for this lens was for an astrophotography trip that was canceled, so I haven’t used it much. Ken Rockwell has a good review, if you want to look that up. First thing to know is that is a DX lens, so only some utility on a FF body. Obviously, you would want to have a use for the f2.8, or you would look at lighter and less expensive options like the Nikon DX 10-20. It does work on the Nikon Z50 with the FTZ adapter, which adds a little future-proofing. I suggest posting the question as a stand-alone post to get more feedback.

When you are looking through the lens the aperture is wide open, when you press the shutter button , the aperture closes down to the f/stop you have set. You don't have to do it manually

Perhaps one half of the question can be rephrased to “noise level or zoom range”. You can boost the iso but you can’t stretch the zoom range.
A 1.5x zoom ratio is rather limiting. If the two lenses both had wider ratios, it might be easier to just sacrifice some range to gain some speed.
Example would be 24-105/4.0 or 28-135/3.5-5.6 where the user choose to settle for the slightly shorter long end to avoid slowing down to f/5.6.
A one stop difference in noise may be no problem depending on the scene, and if the shot calls for just a bit more DoF then the question is moot cuz f/2.8 is out the window anywho.
IOW oversimplifying the decision doesn’t really answer the question.

[quote=steve L]So...my first post to ask for opinions from the congregation, so go gently into that good night !!
Believe I should choose/lose one [one, I forgot I had for a bit]
a: Tokina 11-16 Pro DX 2.8
b: Nikkor 12-24 AFS 4.0 G ED
Cameras are D7100, D500, D700 [though, not an issue, i presume]
What do I shoot.....everything..
Thanks to all in advance, appreciate all the information gleaned here !!
Thanks
Steve
Sell the Tokina, D7100 and D700. Keep the 12-24, D500 and purchase a Nikkor 24-120 f4.0
