SV555 New Upgrade, New Experience

We' ve updated the sandblasting process from a 320-grit to a 280-grit finish.This gives the new version a more refined, matte texture that not only looks better but also resists fingerprints. You'Il see a clear dlifference in the side-by-side comparison we' re showing here. Next, we've managed to reduce the weight of the tube by over 90 grams. This makes the new version lighter and more portable. The third improvement is in the reduced lens hood. The outer diameter of the lens hood is reduced from 97mm to 93mm and the wall thickness from the 3mm to 2.5mm. This makes the hood more compact and lightweight while maintaining its functionality. Finally, we’ve increased the focus travel from 2.67mm to 3.22mm. This provides a smoother and more precise focusing experience, especially for astrophotography.
