Impressions of the Sigma 40 1.4

The speaker expresses excitement and anticipation about trying out the Sigma 40 1.4 lens. The lens has a strong reputation, and if it lives up to its expectations, it could significantly impact the way the speaker captures images.

Astro Photography Enthusiasm

The speaker conveys their passion for astrophotography and acknowledges the support from their audience, both new and returning. They express gratitude for their followers and welcome newcomers to their channel.

Testing the Game-Changing Lens

The speaker discusses the potential game-changing capabilities of the lens, specifically its wide aperture (f/1.4). They explain how using this lens could drastically reduce exposure times, allowing for more efficient nighttime photography, potentially transforming the way they approach and shoot panoramas.

Experimental Photo Shoot

The speaker embarks on a night photography session to test the Sigma 40 1.4 lens. They choose a picturesque location with an old pine tree against the backdrop of the Milky Way. The primary focus of this session is to evaluate the lens's performance, rather than capturing an award-winning image.

Waiting for Twilight

The photographer waits for the lighting conditions to get darker, preparing for an astrophotography session. This crucial step is essential to achieve better results for capturing the night sky.

Foreground Preparation

Before the Milky Way comes into view, the photographer takes shots of the foreground. To reduce noise in the final image, the photographer uses an unconventional exposure setting: 30 seconds, f/1.4, and ISO 2000, which provides a shallow depth of field but is acceptable for the foreground shot.

Capturing the Milky Way

As the Milky Way reaches the desired position, the photographer takes a test shot at f/1.4, ISO 640, and 50 seconds. Upon reviewing the image, the photographer is pleasantly surprised by the sharpness and corner-to-corner perfection, expressing excitement and satisfaction with the lens's performance.

Panoramic Astrophotography

The photographer experiments with panoramic astrophotography using the 40mm lens. This approach involves capturing multiple rows and columns of images, totaling around 13-14 images wide and four rows high. The photographer successfully completes the panorama quickly using one-minute exposures, making the most of the lens's wide aperture and high-quality performance.
