In this video, Julia Trotti does a prime lens comparison with portrait photography.
You’ll learn about focal lengths, background-to-foreground separation and compression, and distortion.
Take a look.
In this video, Julia compares the following lenses using her Canon 5D MkIII:
Julia first tests the lenses shooting full body photos with her model, Maralyn, from the same standing position to show how much background compression each lens shows, as well as the bokeh.
Then she does shots where her model fills more of the frame. To do so, she moves closer and further away to get the model in roughly the same position in the frame but showing what happens to the background in each shot.
The Sigma 24mm has the least background to foreground compression (shows more of the background) when doing full body shots.
The 85mm and the 135mm have great compression, and large background to foreground separation, with no distortion. The 135mm has the most background to foreground separation and compression of all these lenses.
Be sure to watch the video to see the photo examples that detail how the background compression is effected by each lens.
