Quick Answer
The SquareHood for Voigtlander 28mm Ultron M Mount uses a bayonet mount that replaces the native LH-4N hood, and it works with the original round lens cap and filters.
Bayonet Mount vs. Screw-On
The SquareHood attaches via a bayonet mount, not a screw thread. This means you align the hood with the lens and twist it into place, similar to how you attach the original Voigtlander LH-4N hood. The bayonet design provides a secure lock and quick on/off, but it requires the lens to have the matching bayonet ring.
Cap and Filter Compatibility
A key advantage of this SquareHood is that it retains the ability to use the original round lens cap. You don't need to buy a separate cap. Additionally, you can use a filter with the hood attached, though you should check that the filter thread matches the lens. Note that no cap is provided with the hood itself.
Frequently Asked Questions
How do I mount the SquareHood on the Voigtlander 28mm Ultron?
Align the hood's bayonet tabs with the slots on the lens's bayonet ring. Press the hood gently against the lens and twist clockwise until it clicks into place. To remove, press the release button (if present) or twist counterclockwise while pulling gently.
Will the SquareHood work with a filter?
Yes, a filter can be used with this lens hood. Install the filter on the lens first, then attach the hood. Ensure the filter diameter matches the lens's filter thread (the Voigtlander 28mm Ultron uses a 39mm thread). Check that the filter is not too thick to interfere with the hood's bayonet lock.
Does the SquareHood come with a lens cap?
No cap is provided with this hood. However, the hood is designed to work with the original round lens cap that came with the Voigtlander 28mm Ultron. Simply attach the cap over the hood as usual. Keep your original lens cap handy; you won't need to buy a new one.
