1. Make the scenery output more exquisite picture quality
Compared to the zoom lens in the 24mm focal length (for example: 24-70mm/16-35mm), 24mm fixed Gio resolution is higher, if it is coupled with the high pixel model camera, but also the powerful, the output of more exquisite quality. The pursuit of high quality scenery photos You can consider upgrade 5ds/5dsr/d810/a7rii a series of high pixel model camera, I believe than the author in the following figure to 1dx+sigma 24mm F1.4 art photography More perfect!
24mm, F16, 1/125sec, ISO, Av-mode, evaluative metering, No-flash
2. With the scene portrait
Traditional portrait is mostly a bust or a big head close-up, accustomed to use 105mm/135mm focal length as portrait shooting lens, in recent years, this situation has been changed, take the scene with a picture of more elements, create a broader, photos can provide more information and perspective extension, you can use the scene to foil the main personality traits, The focus of the lens is shortened to the 50mm,35mm, and the 24mm fixed-focus mirror recommended by the author is enhanced.
F1.4, 1/1600sec, ISO, Av-mode, Partial metering, No-flash
F3.2, 1/160sec, ISO, Av-mode, evaluative metering, flash-on
F1.4, 1/1250sec, ISO, Av-mode, Partial metering, No-flash
3. Low light artifact
General fixed Gio of the largest aperture is generally larger than the zoom mirror, look at the figure below, F1.4 diameter is already F2.8 twice times,? Wan convex cannibals fatty support Jake The specific difference is how much?
Take a look at the difference between direct comparison F1.4 vs F1.8 vs F2.8:
Typical level One-third aperture value scale
f/# 1.0 1.1 1.2 1.4 1.6 1.8 2 2.2 2.5 2.8
A) Aperture difference
To a three-level aperture value scale:
–f1.8 vs F2.8 4 X1/3 level, equal to level 1.33 aperture
–f1.4 vs F2.8 6 X1/3 level, equal to level 2 aperture
B) Shutter Difference
Was walking my costing 烀 to climb Ben Chung Yuen セ Locust "sour σ a huge moxa?" The following are the camera settings in M-mode, ev+/-:0, iso:800, in the camera to observe the actual display of the shutter value, is not an armchair!
–f1.4, 1/100 (0.01sec)
–f1.8, 1/60 (0.0167sec)
–f2.8, 1/25 (0.04sec)
Conclusion:
F1.8 vs F2.8: Use 0.023sec more, pay 2.4 times times shutter time, 4 x 1/3 shutter, equal to 1.33-level shutter
F1.4 vs F2.8: Use 0.03sec more, pay 4 times times shutter time, 6 x 1/3 Shutter, equal to 2-level shutter
The big aperture does allow for a higher shutter value in a low light environment, allowing you to preserve the atmosphere without the need for a flash to fill the light. As if the following demonstration photos, black paint a stage, open F1.4 and 10,000iso only to lock the shutter value in 1/60 seconds (haha, the author of the hands of the residual, safe shutter 1/25 are not stable, to a higher point is safe!)
F1.4, 1/60sec, ISO 10,000, Av-mode, evaluative metering, No-flash
4. Know how to use, shoot people is a good partner
Portrait, believe that a lot of film friends care about both the photography theme, regardless of male and female friends, a large fine or paternity photography, photography can not be separated from the portrait of the relevant discussion, the 24mm Gio is appropriate? The author such suspense is certainly suitable! Whether straight, banner, Day view, night, indoor and outdoor, portrait with the king, 24mm is also a good partner.
F5.6, 1/80sec, ISO, Av-mode, evaluative metering, REMOTE-FLASH1
F1.4, 1/1600sec, ISO, Av-mode, Partial metering, No-flash
5. Large amount of light, favorable for the dark position focusing
The amount of incoming light directly affects the camera focus response, especially in the dim light of the indoor or outdoor environment shooting, in addition to directly adjust the aperture to increase the amount of light, the lens itself has a direct impact on the Mirror Group, and light each through a mirror will be weakened, fixed-focus Mirror Group Congenital design has been more simple than the zoom lens, such as: Nikon 24mm f1.8g Ed fixed coke (9 Group 12 pieces) vs Nikon 24-70mm f2.8e ed VR Zoom (16 group 20 pieces)
According to the Dxomark Web site data show that the above two lenses, the amount of light into the Gio is almost a full, in the same aperture and ISO photosensitive premise, the Gio of the original body into the light volume has directly increased the performance of the camera autofocus.
F2.8, 1/64sec, ISO 2,000, Av-mode, evaluative metering, No-flash
6. Wide-angle worse, worse off than
24mm is a wide-angle focal segment, the angle of view is 84 degrees, although there is no 16mm and 20mm as a broader cover, but the general indoor and outdoor are enough to cope with, than 35mm wide, shooting a three or a tour of the sights, are enough.
The following model diagram, 24mm view, the mall shadow large sets can be covered?
F14, 1sec, ISO, Av-mode, evaluative metering, No-flash
7. One machine and one mirror
If it is not a professional photographer, photography needs to travel, food and daily life, shadow friends you do not have to count your hands on the use of different lenses? Which one is the tallest? I believe many friends can not do without the standard variable Gio and Tianya mirror a kind of more popular than the lens. As I mentioned before, 24mm fixed Gio has wide-angle characteristics, plus the big aperture plus holding, whether the holiday to local or outbound travel, a mirror to Pat food, portrait, scenery theme 24mm Mirror has covered 8, 90% demand.
8. Shallow depth of the same, wide angle to maintain the three-dimensional
A lot of time to shoot wide-angle use of ultra-wide zoom loss of shallow depth of the fun, 24mm fixed the focus of F1.8/More aperture of the F1.4, to take a wide range of shallow depth of the same can. Make the Circle F1.4, you can highlight the main body and strengthen the picture three-dimensional.
F1.4, 1/320sec, ISO, Av-mode, Spot metering linked AF, No-flash
Postscript
The above are the author of the 24mm Mirror some of the personal view of the law and advice, there is no camera lens is perfect, as long as they think appropriate, play their characteristics and take a good work is enough, looking back on these two years, the original has been different from the focus of fixed focal length has been introduced, I hope there is always a section for you! ^_^
