I apologize - I could have worded that better.StudentOfLight said:A reasonable compromise for some people, but Me, I'm completely unreasonableAntono Refa said:A reasonable compromise in an age when distortion can be fixed in post processing.StudentOfLight said:Yes, it has very high distortion.Antono Refa said:StudentOfLight said:f2.8, really??????
Take Nikon's 13mm f/5.6 (which weighs around 1.2kg) as a comparison. Now factor in a lens that's 11mm is wider, f2.8 is stops faster and the fact that it's a zoom... and the weight for this rumored lens would probably be around 10kg, if not more.
The only way they could reduce weight would be by compromising on build quality and optical performance. What would be the point of that?
The Nikon 14-24mm f/2.8 is 1mm longer and 200g lighter. Did Nikon compromise on the build quality & optical performance of that lens?![]()
All lenses after f/11 are killed by diffraction, it's not really a factor at all but below that range, the 16-35mm f4 is better at every aperture.SoullessPolack said:rrcphoto said:raptor3x said:dilbert said:tianxiaozhang said:RLPhoto said:I kinda lost my burning for an UW with the 16-35 f/4L.

That good? Worth upgrading from 1740?
The 16-35/f4L makes the 17-40 look like the kind of lens you get with those camera plus lens plus film things. Yes, the 17-40 really is that bad and if you didn't realise it, get the 16-35 (or just for a day) and you'll soon see why.
Really? The 16-35 is certainly the better lens, but you might be exaggerating just a tad.

What landscapes do you see that are shot at f/4.0? The f/8.0 review is much more applicable, and an f/11.0 or f/16.0 would be even better comparison of the two.

Then, as you probably know, there are hardly any rectilinear lenses wider than 16mm. If you're not willing to spend $2,800 on one of those few, that's your choice, no need to say you're sorry.
[I wouldn't spend $2,800 on this lens, if released, but I will wait patiently for a price drop.]

Rectilinear = a wide angle lens which is not a fish eye. They aim to render straight lines perfectly straight, even at the edge of the frame. If you were to fill the frame with a flat subject (eg a test chart) it would be capable of taking a distortion free image of it if lined up perfectly.
Rectilinear lenses do suffer from other forms of distortion which fisheyes (especially stereographic fisheyes) are less susceptible to - any subject which is three dimensional really. Take a group photo for example - people near the edges of the frame are stretched. Anything in the corners looks even more extreme. Even photos of innocent stuff like grass filing the bottom half of the frame and sky in the top - the details in the grass blades will take on the characteristic stretch into the corners, as will any clouds.
The wider the rectilinear lens, the more pronounced this effect will be. In certain scenarios it can be something to be embraced (although not group shots!)

What landscapes do you see that are shot at f/4.0? The f/8.0 review is much more applicable, and an f/11.0 or f/16.0 would be even better comparison of the two.
quite a bit actually. if you are looking at f/11 and f/16 then use any crappy lens, because your diffraction will smear enough that you don't care anymore.
if you can't get enough Dof at around f/4 to f/6.3 when rolling with a 16mm then you're doing something wrong.
even on a 6D with a focus distance of 20 feet, you have your depth of focus being from 11 feet to infinity. wide open. and this is with the CoC being 2 lp versus the much easier .030mm that most people use.
so umm yeah.. what were you saying again?
All lenses after f/11 are killed by diffraction, it's not really a factor at all but below that range, the 16-35mm f4 is better at every aperture.
Do you mean pixel size?vscd said:All lenses after f/11 are killed by diffraction, it's not really a factor at all but below that range, the 16-35mm f4 is better at every aperture.
Diffraction depends on your sensorsize, too. Not your lens, only.

Yes you are correct, a fully rectilinear corrected lens is one where straight lines stay straight in the frame. Two good examples of this are the 14L and Sigma 12-24 HSM (mkI). Circles become more egg shaped as the approach the corners of the frame. All wide lenses show distortion somewhere, either lines or circles.
Most rectilinear wide lenses are corrected to some degree but not fully. This is to allow a compromise and versatility. A fully corrected lens distorts circles (faces) so a design compromises is employed to keep straight lines fairly straight (a slight curve is usually not too noticeable and quite acceptable) but keeps the circles fairly circular (unless you shoot up close). The 16-35IIL is a great example of this. Most lens designers assume the user will correct in Lightroom / Photoshop if they need a more extreme correction. I find the look I get out of the 16-35IIL looks quite natural and is kind on the eye. A 14L, TS-e 17L or Siggi 12-24 tend to look very angular and isn't how the human eye sees the scene.
Where as fish-eye lenses are the complete opposite. Circles stay circular but straight lines curve as they approach the edges of the frame.
This is why I have more than one wide lens in my collection and why I am REALLY looking forwards to this new lens from Canon. It could be a game changer.
