I tried this filter on my Sigma 17-50 and the result is really amazing. The product looks great in its really high quality packaging and is easy to carry in your pocket. The photographic rendering is of a high standard for a low price. I find the tongue very interesting, it allows a better grip at work.

A very good price/performance ratio

We just love this binoculars!

They are brilliant, I can see so much from this, the conclusion is excellent, really well done, would recommend to anyone.

Haven't had a chance to try the 50/1.2L yet... but it can't be that much better than its little brother here. I like using this lens on my new 5DM3 and just as much on the 1DMK 4. A feast for the eyes on both cams in terms of image quality. The AF is sufficiently fast thanks to USM and also sits precisely. The weight is pleasantly light and therefore easy to handle. Low-light shots indoors, even in candlelight, are easily possible outdoors. There really isn't much else to write. The price is definitely acceptable for this quality. A lens hood is a MUST, especially for outdoor shots! Unfortunately, as with all Canon NON-L PRODUCTS, this has to be paid for separately. An unreserved purchase recommendation from me.

Now one might think, why should you spend almost € 50 to buy this when there are similar products for € 10? Well, if that's what you think, then you're obviously not a professional photographer, are you? You see, it's the quality of the glass you pay for and the coating that is used on it! The finer the glass, the better the light transmission, which is the key here! So definitely worth every penny when I tested it and will add photos to this review later! Was also impressed with the packaging as an item like this requires the utmost care!

1 star missing because it doesn’t really work well with the Takumar 50 1.4 (the lens doesn’t focus to infinity as others have mentioned). The other four stars are because otherwise it is built well and I’m sure will work with most other lenses. Using it on a Sony A7R III and it gives me nice and sharp images even with that sensor so well machined I’d say. Although I also have the same brand adapter on a Fuji XT2 and it still focussed to infinity (though it did get a little stiff at that end) so I’m not sure if they’re all manufactured exactly the same or it there is a difference from version to version. All in a all a good product.

I got this because I wanted to have 1/50 shutter speed and a wide aperture in an outdoor shooting environment - I am video recording. It works well. One thing you should know, you cannot put your kit lens lid on this filter, otherwise you need to remove it.
