How do I know if my crop sensor is a factor?

Not correct.

Lens companies do not adjust the focal lengths based on crop or full frame cameras. They could care less about your crop sensor. They make a 16mm lens. What happens when it leaves the factory is not their concern.

I'm not talkign about focal length anymore, I'm talking about field of view.

FOV is a direct result of the focal length...so they are essentially the same thing when you talk about them.

That's why we say 10mm is wide, instead of saying that 10mm is short....and so on.

18mms using an EF-S lens (made for a crop sensor) on my crop sensor camera would give me the same field of view as 18mms using an EF lens (made for a full frame sensor) on a full frame camera... correct? (If that's not correct, then I think that's where I'm getting messed up.)

The highlighted part is where you went wrong. Take that part out and you're on track.

And it doesn't matter, because you aren't using a full frame camera.

So this is correct...

18mms using an EF-S lens would give me the same field of view as 18mms using an EF lens correct? (If that's not correct, then I think that's where I'm getting messed up.)

I'm seriously never going to understand this.

 

[Bitter Jeweler]

Yes!

I'm guessing you have a tendency to over-think things.

The issue is only complicated because everything is compared to the 'old standard'. But since you're not using a 35mm film camera along side your digital SLR, there is no need to compare anything...all of that crop factor stuff is invalid (to your situation).

FX & DX are lens mounts, not sensor sizes. The same with EF and EF-S, which are Canon when FX & DX are Nikon. Not relavent in this thread.

Not quite right. FX is a Nikon camera with a full-frame sensor. All Nikon FX cameras (D3, D3s, D700) will accept and mount DX-Nikkor lenses, which are lenses that have reduced image circles, compared to lenses designed for full-frame coverage, which is roughly a 43mm diameter image circle at the film plane.

Nikon does NOT have a different lens mount, and a different rear lens cap style, for DX or FX lenses, the way Canon does with its EF and EF-S lenses.

In Nikon-speak FX is a *****sensor size****. There exist absolutely ***NO**** Nikkor lenses that carry the FX designation. The only place FX appears is ON NIKON BODIES that have FX sensors.

There are a handful of Nikkor lenses that carry the DX designation, but it has nothing to do with the lens mount: they will mount onto any Nikon F-mount body....DX Nikkors will accept any Nikon rear lens cap. DX Nikkors will even shoot images on FX format cameras--in some cases, almost filling the entire 43mm diameter image circle of FX.

Yes!

GREAT!

Thanks for the humorous image and the giggle I got out of it as a result... and your right... I'm very good at over-thinking... but at this point I need to just understand this, relevant or not.

And it's *probably* not going to happen right now because my head now hurts and I'm hungry.

So... I'm going to go get a stromboli.

This might help in some way of your FoV brain fart.

Maybe if you read what was written, and understood it, you'd realize what a ride you Canon lovers are in for with regard to the uselessness of EF-S lenses..and rear lens caps...

There's a fundamental difference you seem to be ignorant about...

an EF-S lens in a Canon mount is as useless as teats on a boar on a 1.3x or a full-frame Canon body...a Nikon mount lens that is DX is usable on both crop- and full-frame sensors...

Maybe you're just not quite smart enough to realize the underlying difference between taken advantage of (Canon), and being give a full line of choices in what your lenses will actually FIT ONTO...(Nikon).:thumbup:

Pfft keep this up and I'll throw springtails at you I will!!!

and my end caps fit on all my lenses no matter which is which

 

[Big Mike]

One last thing.

So do you want a wider view than you get with your current 18mm (18-55mm) lens?
Or do you just need a larger maximum aperture?

If you are OK with the angle of view you get with your current lens, then you could get something like the Canon EF-S 17-55mm F2.8 IS, or the Tamron 17-50mm F2.8 or Sigma 18-50mm F2.8 or Canon 16-35mm F2.8 L.

If you want something wider that also has a larger max aperture...then the Tokina 11-16mm F2.8 is the one you want.
