What is the Sony ALC-SH121?
The ALC-SH121 is a petal-shaped, bayonet-mount lens hood designed for the SAL70400G2 70-400mm F4-5.6 G SSM II lens. It helps reduce flare and ghosting while providing physical protection for the front of the lens.
Which lens is the ALC-SH121 compatible with?
The ALC-SH121 is designed exclusively for the Sony SAL70400G2 (70-400mm F4-5.6 G SSM II A-mount lens). Its petal shape is optimized to shade this telephoto zoom without causing vignetting.
Is the ALC-SH121 already included when I buy the SAL70400G2 lens?
Yes, the ALC-SH121 hood is supplied in the box with the SAL70400G2 lens, along with front and rear caps and a carrying case. You would typically purchase it separately only as a spare or replacement.
How does the ALC-SH121 lens hood improve image quality?
It blocks stray light to reduce flare and ghosting, which helps improve contrast and clarity. Its inner surface uses a non-reflective felt lining to further prevent internal reflections.
Can I use a polarizing filter with the ALC-SH121 attached?
Yes, the hood includes a small access door that lets you adjust a 77 mm polarizing filter without removing the hood.
Does the ALC-SH121 protect the lens?
In addition to reducing flare, the hood provides added protection against impacts, bumps and scratching of the front element. It also acts as a partial shield against rain, dust and accidental contact, as is typical for telephoto lens hoods.
Can the ALC-SH121 be reversed for storage?
Yes, the bayonet-mount hood is reversible on the lens, allowing it to be mounted backward for more compact storage.
What are the dimensions and weight of the ALC-SH121?
The hood measures approximately 4 1/2" x 4 3/8" (113.4 x 110.0 mm) in diameter by length and weighs about 2.8 oz (78 g).
How much does the Sony ALC-SH121 lens hood cost?
MSRP is listed as $82.99. Given that, these models can go on sale from time to time, and there are several other opportunities to save on price like through their group discounts for education, healthcare and military/veterans (ID.me & Unidays) along with their free loyalty program that gives up to 5% back in points.
Should I buy a third-party hood instead of the ALC-SH121?
The ALC-SH121 is designed specifically for the SAL70400G2's optical design, while third-party 77 mm screw-in hoods are universal and not optimized for this lens. For the best results, look specifically for the Sony ALC-SH121.
