## Description

desertcart.com : K&F CONCEPT 43mm MCUV Lens Protection Filter Ultra Slim 18 Multi-Coating | Optical Glass UV Lens Filter with Cleaning Cloth (K-Series) FV301 : Electronics

Review: Protects my lens and my soul! - Got it for my EF-S 55–250mm f/4–5.6 IS. Worth It. Protection: I shoot outside a lot- car shows, dirt, pollen, flying bugs with attitude, and this thing’s been a great first line of defense. I'd rather clean or replace a filter than risk scratching actual glass. Bonus: no anxiety wiping it with a t-shirt if I have to. Optical Clarity: No weird color cast, no ghosting, and it hasn’t affected sharpness at all—even at 250mm. I was worried it might dull the image, but nope. Photos still come out crisp and contrasty. (note I have to stop this lens down to like f8 anyway as its pretty soft at 250) Build Quality: It’s super slim, threads on smoothly, and doesn’t feel like the bargain bin trash you sometimes get with cheap filters. Doesn’t get stuck, doesn’t rattle, and doesn’t look like a toy. ⚠️ Important Note: (I used an EMOJI, so you better read this!!!) CLEAN YOUR LENS WELL BEFORE PUTTING THIS ON. It threads on fine, but trust me, you don’t want to keep taking it off and on. Put it on once and leave it. Any dust, fingerprint, or oil on the front element WILL show up in your shots like a nasty watermark you didn’t ask for. Treat it like applying a screen protector, clean, then cover and LEAVE IT ON. Bottom Line: If you’ve got the 55–250mm or any 58mm filter size lens, grab this. Cheap peace of mind, no image degradation, and it saves you from the heartbreak of scratched glass or sneeze damage mid-shoot.
Review: Works with PVS-14 Style night vision goggles - Originally ordered these as a replacement sacrificial lense for my RNVG dual night vision goggles that utilize the PVS-14 style lenses. They screwed on perfectly and I didn't notice any additional blurriness. Cheap and effective. Could be worth stockpiling these if night vision training is your thing and you consistently bump your nods into things. Time will tell how durable it is but it feels like the glass and protects against direct lense scratches so it's durable enough for me.

## Features

- Lens Protection & Prevent UV Ray: MCUV filter has two functions, one is to prevent UV ray and weakens the blue tone in images caused by UV, ensuring clarity and color. Another is to protect the lens away from dust and scratches.
- Import AGC Glass: Made by importing AGC optical glass with a CNC-Non-Slip design frame for easily remove and installation, 94% transmittance ensures HD image quality, and no negative effect restores true color.
- 18 Multi-Layer Nanometer Coatings: Double side multi-layer coating, protects the lens and also reduces reflection coming from the filter self.
- Wide Angle Lens No Vignetting: UV filter only 3.3mm thickness with double side polishing technology ensures no vignetting the images are still clear enough even on the telephoto lens.
- Note: This UV filter only fits a 43mm camera lens, please verify your lens size before ordering it. The number beside the Ø (diameter) symbol represents your lens size, please choose the same size filter.
- K&F CONCEPT is the world's No.1 brand in terms of lens filter online sales volume among camera-accessory-focused brands. Source: Euromonitor, 2024 data.

Works as intended and keeps my camera lens glass protected. I haven't noticed any change in image quality. Great value for the money.
