Tiffen 39mm UV Protector Filter

Screwed this onto my vintage 35mm and it threads perfectly smooth, no wobble. Image quality is unchanged but I feel a lot better about shooting near the ocean now.

Wasn't expecting much from a simple UV filter, but this one has zero noticeable effect on image sharpness. The thin metal ring doesn't cause any vignetting on my wide lens, which is a nice bonus. Feels solid enough for everyday protection.

I was worried a filter might degrade image quality, but the glass is so clear I honestly can't tell it's on there. Screwed onto my 39mm lens perfectly and now I don't stress about dust or scratches at all.
