Which F Number in lens is Suitable For Architecture and Urban landscape photography

i am Architect and i do Architecture Photography 

 

i am Using Canon 6D with Lens Canon 17-40 F4

 

Ususally the sweet Spot in Architecture & Urban Landscape photography for me is F8 - F11 , Ususally i shoot in F8 for more sharp Foucus .

 

i can see in market that the New 16-35 F2.8 Mark III is now realesed By Canon 

 

So is the Bigger Appreature lenses like the 16-35 F2.8 Mark III Considered Better in photography to make the image sharper ? even if i use the F8 in suvh lens ?

 

I am really hesitated according to my budget , as i i need to invest  either in Canon Tilit Shift 17mm F4 Or i go for 16-35 F2.8 mark III  instead of the 17-40 i am using now ?

 

Website below contain the Photography works i ususally do , incase you would like to have a look about what kind of photography i ususally do

If you are shooting f/8 from tripod, then you have less need for a wide aperture lens.  A T-S would be a better add.

 

Invest in a really good tripod and head.  I like to shoot landscapes, and have found a leveling base to be very useful.

Does Photoshop do a good enough job with perspective distortion? If not, a tilt-shift should be your next purchase.

Whether you go T&S or use Photoshop, you will have a learning curve.  So beware, that will be your future as either will do the job.

There is no doubt the ef 16-35 F2.8 Mark III is a better lens. Much better !  The ef17-40mm is not all that good in the first place but I doubt the new lens would benefit you much.  Looking at what you shoot currently anyway.  Almost any WA lens can do that.

 

f8 is a good aperture for you.  The fact the ef 16-35 F2.8 Mark III has a faster aperture means nothing for what you do.  It has a full stop advantage but it only is needed if your shots require more light.  SInce you are using f8, you do not.

As Ernie says, the f/2.8 lens buys you nothing extra in image quality if you do all your shooting at f/8. But it could make focusing slightly easier or faster, because a camera does its focusing with the lens at maximum aperture. Is it worth buying a new lens just for that? Probably not.

While by f/8 it might not buy you much, the further from the maximum aperture you are the better the performance. I would expect f/8 on a f/5.6 lens to be worse than the performance of f/8 for an f/2.8 lens.

That’s exactly what I am thinking the f8 on lens of f2.8 is it really different than the f8 on lens of f4 ?

Not unless they've changed things in recent years. In fact, the idea is to design a lens to have its point of maximum sharpness near the middle of the aperture range, so as not to degrade the performance too much at either end. Thus my Nikon 50mm f/1.4 lens peaked at f/5.6, while my wife's 50mm f/2 peaked at f/6.3. (Both lenses maxed out at f/16.)

 

Note that the performance of the f/2 lens at f/6.3 may have been better (and certainly not worse) than that of the f/1.4 lens at f/5.6. In fact the f/2 was considered the sharper lens and was preferred at any aperture in its range.

It might depend upon your point of view.  Aperture describes a ratio of the lens elements.  Basically, there is no difference between one lens to the next at f/8.  As noted, if you're shooting f/8, you're not going to gain anything by using an f/2.8 lens compared to an f/4 lens.

 

In fact, shooting at narrow apertures is probably undesireable if your shooting architecture and landscape photos.  Unless you're looking for some creative use of depth of field, you really do not need a fast lens.  What you need are sharp lenses that produce rectilinear images without noticeable barrel distortion.  A wide angle, Tilt-Shift, lens is a good tool to have, for your type of shooting.  

If you want to spend money on a lens, look for a super wide angle prime that can produce fairly rectilinear images.  Or, look at a Canon T-S lens, like the 24 mm.  You're going to want to have one of those leveling base adapters on your tripod with a T-S lens.

No one has mentioned the excellent Canon EF 16-35 f/4 IS.  It is as sharp or effectively as sharp as the f/2.8 and half the price and is image stabilized so you can often get by on long shutter shots of architecture without a tripod.  

 

Or or look at spending for the specialist TS lenses.
