Blazar 50mm T2.9 1.8x Anamorphic vs Sony FE 50mm f/2.5 G
When comparing Sony FE 50mm f/2.5 G and Blazar 50mm T2.9 1.8x Anamorphic, which one is better?
1. Largest Aperture Comparison
The Sony FE 50mm f/2.5 G has the largest aperture of the two lenses at 2.5 compared to the 2.9 aperture of Blazar 50mm T2.9 1.8x Anamorphic. This means that you get more light to your sensor using Sony FE 50mm f/2.5 G wide open, and therefore it might be a better lens in dark situations.
Winner: Sony FE 50mm f/2.5 G
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.
2. Anamorphic Comparison
Winner: Blazar 50mm T2.9 1.8x Anamorphic
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.
3. Stabilization Comparison
Neither Blazar 50mm T2.9 1.8x Anamorphic or Sony FE 50mm f/2.5 G 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.
4. Autofocus Comparison
In regards to autofocus, the winner is Sony FE 50mm f/2.5 G since the other lens in this comparison, the Blazar 50mm T2.9 1.8x Anamorphic does not have autofocus at all — it is a manual focus lens.
Winner: Sony FE 50mm f/2.5 G
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.
5. Macro Comparison
Neither Blazar 50mm T2.9 1.8x Anamorphic or Sony FE 50mm f/2.5 G 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.
6. Weather Seal Comparison
Sony FE 50mm f/2.5 G features a weather sealed design while Blazar 50mm T2.9 1.8x Anamorphic does not. This means that Sony FE 50mm f/2.5 G 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: Sony FE 50mm f/2.5 G
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.
7. Full Frame Comparison
Both Sony FE 50mm f/2.5 G and Blazar 50mm T2.9 1.8x Anamorphic cover a full frame sensor and can be used on full frame cameras as well as cameras with smaller sensors.
Winner: Tied — both have this feature
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.
