Fulfilled its role of protection (non UV filter)

This non UV filter (hence the confusion of some between this model and the UV a little more expensive) is very good.
Purchased to protect against dust and shocks my 70-200 ... he perfectly fulfilled its role. As we can see from the photo, the glass is not just stuck in a gutter but clearly sealed on the ring. No game between the glass and the ring, so the dust will be more difficult to pass some filters that rotate freely in their ring.
And especially the cleaning is found in ease, which is also the purpose of such a purchase.

Transparency is there and the level of finish too. Anyway if you need a 77mm filter that is not a target of 100, so as to build on the quality ...

I have put only 4 stars this filter as it arrived well conditioned but it was a bit dusty in the box, it is not very serious, he just had to clean it but I would have preferred to mount it directly out of the box like Canon filters (but hey there is a price difference too). Otherwise no complaints, very satisfied with this filter.

I will not go into the UV or not UV debate, some say it's best for autofocus and respect for other colors it is better to protect the sensor and its eye, it is up to you depending on your usage ... I had enough trouble choosing between the two models ... ;-) Hoya those interested will find forums photos of several kilometers ...

Anyway since I have it, there was never any need to dust off the lens of my goal. I can not recommend buying such a filter together with your lens and mount it on the new goal. You are thus sure not to damage the factory processing your goal and avoid some fogging phenomenon between the lens and lens ...
