Wide-angle lenses for landscape photography: When 20, 25, or 35 mm make sense

In a landscape, rarely is everything equally important. A rock lies directly in front of the camera, a ridge several kilometres away. Between them lie water, forest, clouds, and light. The focal length changes how these layers relate to one another in the image.

On the Hasselblad X System, 20, 25, and 35 mm correspond to roughly 16, 20, and 27 mm in full-frame terms. Because of the 4:3 format, the horizontal and vertical coverage is not completely identical to that of a 3:2 full-frame sensor.

For composition, what matters most is what happens within the frame: 20 mm takes in more of the immediate surroundings. 25 mm trims the outermost areas of the frame. 35 mm gives subjects in the middle ground and background more presence.

What Focal Length Is Suitable for Landscape Photography?

The choice of focal length starts with the spatial structure of your subject. The key factors are the distance to the foreground, the desired size of the main subject, and the constraints of the location.

The current 100 MP cameras on the X System use a 43.8 × 32.9 mm medium-format sensor. That corresponds roughly to an aspect ratio of 4:3.

With a similar horizontal field of view, 4:3 offers relatively more vertical image area than 3:2. This creates extra latitude when foreground, horizon, and sky are all part of the composition. With very wide focal lengths in particular, this extra height can matter more than even more space at the sides.

20 mm for Closeness and Space

On the X System, 20 mm is the widest focal length of XCD 3,2-4,5/20-35E, and corresponds roughly to 16 mm in full-frame terms.

The angle of view lets you get very close to the foreground while still including a large part of the surroundings.

On a rocky coast, a structure can begin just a few centimetres in front of the camera while the sea and horizon stay in the frame. In snow, lines in the foreground can lead to a distant ridge. The foreground is not simply added; it takes on a clear spatial function.

The same applies in confined locations. On a rocky ledge, between water and shore, or in a gorge, you cannot move the camera back as far as you like. There, 20 mm takes in more of the surroundings without changing position.

The wider angle of view also places greater demands on the edges of the image. In architectural photography, this edge performance becomes even more evident, because straight lines there run right to the edge of the frame.

A branch, a bright stone, or an extra line can still be part of the composition at 20 mm, even though it would already fall outside the frame at 25 mm. The high sensor resolution makes even such fine structures visible. With XCD 20-35E, the optical design is intended to support the demands of the 100 MP sensor right out to the edges.

A distant subject also takes up less area within the wide angle of view. A peak that dominates the scene on location can look relatively small in a 20 mm composition.

The extra space is therefore most interesting when it has a function: as foreground, as a leading line, or as part of a clear layering of near and far.

25 mm for Balanced Wide-Angle Compositions

The difference between 20 and 25 mm is particularly noticeable at the edges of the frame.

Elements that are still part of the composition at 20 mm may already fall outside the frame at 25 mm. The sense of spaciousness is preserved, while the outermost areas carry less visual weight.

At a mountain lake, the shore can still serve as the first plane without taking too much of the frame from the distant mountains. In a forest, the edges of the frame are easier to control. On a coast, the surroundings remain present without every structure at the sides having to be part of the composition.

25 mm is therefore not just an intermediate step between 20 and 35 mm. The angle of view holds foreground and distance in a balance of its own.

On the X System, this focal length can be used in two ways. XCD 20-35E covers 25 mm within its zoom range. XCD 2,5/25V offers the same nominal focal length as a prime and therefore a comparable angle of view.

XCD 25V offers f/2.5, focuses from 25 cm, and weighs 592 g. The focus distance is measured from the sensor plane, not from the front element.

The short focus distance widens the scope for foregrounds. Meanwhile, f/2.5 provides more light reserve as daylight fades. Hasselblad explicitly lists night and astrophotography as intended uses for the lens.

In daylight, this maximum aperture is not always decisive. At dusk or under a starry sky, however, it changes the way you work far more than a subtle difference in angle of view.

35 mm for Subjects at Greater Distances

@Jiyuan Wang

At 35 mm, the frame becomes noticeably tighter.

At the long end of XCD 20-35E, the horizontal angle of view is about 65 degrees, compared with roughly 96 degrees at 20 mm.

This becomes important when the main subject is not in the foreground.

A distant mountain ridge takes up more of the frame. Layers of mist can be arranged more tightly. In a forest, a single group of trees can be isolated from more complex surroundings. A hut or a person keeps more presence while the landscape context is preserved.

The narrower angle of view does not change the perspective when shooting from the same position. It simply takes in less of the surroundings.

With big landscapes in particular, this can be decisive. A very wide angle shows a lot of space, but it does not automatically give a distant subject more presence. When a mountain edge or a particular fall of light carries the shot, the tighter frame can be closer to what actually draws attention on location.

35 mm on the X System is roughly equivalent to 27 mm in full-frame terms and therefore still a classic wide angle of view.

Focal Length, Angle of View, and Perspective

Focal length and perspective do not describe the same thing.

If the camera stays in the same position, changing the focal length mainly alters the angle of view. In terms of perspective, a 35 mm image taken from the same camera position is, simply put, a tighter crop of a 20 mm shot.

The spatial relationship between a nearby rock and a distant mountain remains the same. This does not account for differences in distortion, edge rendering, and optical rendering.

With 100 MP, the X System offers considerable latitude for cropping. In purely geometric terms, cropping from 20 mm to about 25 mm retains roughly 64 per cent of the original pixels. Cropping to about 35 mm leaves only around 33 per cent. These figures are approximations and assume the same aspect ratio and an idealised geometric model.

Cropping thus provides a reserve for the final frame. However, it replaces neither a missing angle of view nor a deliberately chosen camera position.

If you want a foreground to appear the same size at 20 mm and 35 mm, the camera has to move closer to it at 20 mm. This changes its size relative to the background.

The characteristic near-far effect of an ultra-wide lens therefore results from the interplay of angle of view and distance.

The 4:3 format also shapes this composition. With a similar horizontal angle of view, you have relatively more vertical space available than with a 3:2 format. Foreground, horizon, and sky can thus be arranged in relation to one another within a taller frame.

A wide-angle lens therefore does more than extend the frame. It changes which distances within this frame can remain visible at the same time. The role that position, light, and image quality play in landscape photography beyond this is covered in the main guide.

Prime or Zoom for Landscape Photography?

When choosing between a prime and a zoom, position, light, and weight matter most.

XCD 20-35E for Variable Framing

XCD 3,2-4,5/20-35E covers 20 to 35 mm, roughly equivalent to 16 to 27 mm in full-frame terms. It weighs 805 g and features a 77 mm filter thread.

The zoom range lets you change the frame without giving up the camera position.

This matters wherever movement is restricted. At the edge of a cliff, by a lake, or on a narrow path, the shooting position may already be fixed. The focal length then changes the framing, while the perspective remains the same.

The 77 mm filter thread accepts screw-in filters of this diameter. For landscape photography, this is especially convenient when using polarising and neutral density (ND) filters.

The optical design of XCD 20-35E is tailored to the resolution requirements of the 100 MP sensor. Hasselblad highlights detail rendering right into the edges of the frame.

For wide-angle compositions, this consistency is particularly important, because key visual information is often spread across the entire frame.

XCD 25V for a Fixed Angle of View

XCD 2,5/25V reduces the decision to a single angle of view.

It weighs 592 g, offers f/2.5, focuses from 25 cm, and takes 72 mm filters.

This makes it lighter and faster than XCD 20-35E. These differences matter most when the preferred angle of view has already been decided.

On long hikes, the lower weight lightens the kit. At dusk and at night, f/2.5 provides more light reserve. The short focus distance also lets you include small foreground structures prominently in the composition.

The difference between the two lenses is therefore less a ranking than a way of working.

The 20-35E keeps the framing flexible.

The 25V keeps the angle of view fixed and shifts the decision more to position, distance, and the moment of capture.

Frequently Asked Questions about Wide-Angle Lenses for Landscape Photography

Why does 20 mm on the Hasselblad X System correspond to roughly 16 mm in full-frame terms?

The equivalence factor of the Hasselblad X System is approximately 0.78. This is why 20 mm corresponds to about 16 mm in full-frame terms. However, due to the different aspect ratios of 4:3 and 3:2, the horizontal and vertical framing are not completely identical.

What does the 25 cm minimum focus distance of XCD 25V mean?

The minimum focus distance of 25 cm is measured from the sensor plane, not from the front element. The actual distance between the front of the lens and the subject is therefore shorter. This is particularly relevant when small structures very close to the camera are included in the foreground.

How much latitude does 100 MP offer for cropping?

From the same camera position, a theoretical crop of a 20 mm image to about 25 mm retains around 64 per cent of the pixels, and a crop to about 35 mm around 33 per cent. Cropping changes the framing of the image, not the perspective, and it does not replace a different camera position.

Which filters are suitable for a wide-angle lens in landscape photography?

Polarising filters reduce reflections, but at very wide angles of view they can darken the sky unevenly. ND filters lengthen the exposure time, for example, for water or clouds. Graduated filters help with strong differences in brightness between sky and landscape.
