It adds to the total weight of your camera and it's important to keep the weight low if you get tired in your arms when taking photographs or filming.
2. Lens Mount Comparison
The lenses each feature different lens mounts — the Sigma 105 mm f/1,4 DG HSM Art - Sony features a Sony E while the Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF features a Fujifilm XF — and because of this the preference varies. If you have a compatible camera, then of course that lens will be a better choice for you.
Winner: Tied — It depends on your gear
Regarding lens mount: Popular lens mounts are Canon RF and EF, Micro Four Thirds and Nikon Z. Different lens mounts lets you connect different lenses to camera bodies, but some might not be compatible. This can be helped by using an adapter, like a Canon EF to RF adapter.
3. Largest Aperture Comparison
Both lenses share the same aperture of 1.4 — this means that you may buy both Sigma 105 mm f/1,4 DG HSM Art - Sony and Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF in this regard; they''re the same.
Winner: Tied
Regarding largest aperture: A lower aperture number means that the widest aperture on the lens is larger. This means that more light will hit the sensor and also that the depth of field will be shallower, better separating your subject from the background.
4. Anamorphic Comparison
Neither Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF or Sigma 105 mm f/1,4 DG HSM Art - Sony are anamorphic lenses.
Winner: Tied — Neither have this feature
Regarding anamorphic: Anamorphic lenses are usually used on cinema cameras and squeezes the image when its recorded, which gives the final, stretched out, image oval bokeh and a different angle of view. The most common lenses, however, are not anamorphic but spherical, which gives a spherical bokeh and is a much cheaper lens design.
5. Focus Distance Comparison
Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF features a minimum focus distance of 40 cm while Sigma 105 mm f/1,4 DG HSM Art - Sony has a minimum focus distance of 100 cm. Depending on your shooting style, the Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF might be a better choice.
Winner: Viltrox AF 33mm f/1.4 STM ED IF Fuji XF
Regarding minimum focus distance: The minimum focus distance of a lens is the smallest distance from the lens to the subject you want to be in focus; subjects closer than the lens' minimum focus distance will not be in focus. Whether or not this is important to you is up for you to decide, but some want to take close photos and videos and in those cases it's important to have a lens with a low minimum focus distance.
6. Lens Type Comparison
Both lenses are Prime lenses, which means that you can choose both Sigma 105 mm f/1,4 DG HSM Art - Sony or Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF if you're looking for that type of lens.
Winner: Tied
Regarding type: There are two types of lenses; zoom lenses and prime lenses. Prime lenses have a fixed focal length and cannot be zoomed, while zoom lenses have a focal length range and can be zoomed in to get closer to the subject. Prime lenses are usually lighter, cheaper and let in more light. Zoom lenses are more versatile but are more expensive since they require a more advanced lens design.
7. Aperture Blade Comparison
Both Sigma 105 mm f/1,4 DG HSM Art - Sony and Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF have 9 aperture blades, which means they should both have a similar bokeh shape and roundness.
Winner: Tied
Regarding aperture blades: The number of aperture blades makes a difference because the bokeh is smoother the more aperture blades the lens has. Of course, this does not mean the lens is better in other regards, but it can be an interesting aspect when deciding of a lens.
8. Stabilization Comparison
Neither Sigma 105 mm f/1,4 DG HSM Art - Sony or Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF feature built-in image stabilization.
Winner: Tied — Neither have this feature
Regarding image stabilization: When a lens features built-in stabilization, it will actively help you hold the image steady by adjusting the optical elements inside the lens to compensate for movements. Do remember that lens stabilization is not required, but it may be suitable depending on your specific needs.
9. Autofocus Comparison
Both lenses have autofocus, which means that they're both great at focusing targets while taking photographs or filming video. Just remember, most cameras do not offer good autofocus while filming video.
Winner: Tied — both have this feature
Regarding autofocus: Lenses with autofocus help you focus when shooting pictures or video. If a lens only has manual focus it means that you have to focus manually by adjusting the focus wheel on the lens. Most cinema lenses do not use autofocus and are manual focus only.
10. Macro Comparison
Neither Sigma 105 mm f/1,4 DG HSM Art - Sony or Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF are macro lenses.
Winner: Tied — Neither have this feature
Regarding macro: Macro lenses can focus much closer to your subjects and might be suitable when photographing flowers, insects, wildlife and nature.
11. Weather Seal Comparison
Sigma 105 mm f/1,4 DG HSM Art - Sony features a weather sealed design while Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF does not. This means that Sigma 105 mm f/1,4 DG HSM Art - Sony is a much better choice if you know that you'll use the lens in harsh environments, where moist, rain or dust is present.
Winner: Sigma 105 mm f/1,4 DG HSM Art Sony
Regarding weather seal: A lens that is weather sealed will perform better over time if you're using the lens in harsh conditions where it's wet or dusty. It may not matter if you're merely using your lens in a studio or in your home.
12. Full Frame Comparison
Sigma 105 mm f/1,4 DG HSM Art - Sony covers a full frame sensor while Viltrox AF 33mm f/1.4 STM ED IF - Fuji XF does not. If you have a full frame camera then Sigma 105 mm f/1,4 DG HSM Art - Sony is the only choice for you in this comparison.
Winner: Sigma 105 mm f/1,4 DG HSM Art Sony
Regarding full frame coverage: All lenses do not cover full frame sensors, but not all cameras are full frame cameras either. If a lens covers a full frame sensor it can be used on all cameras with a matching lens mount, both full frame and crop sensors, except for medium format cameras.
