Great webcam. Excellent looks. The thing that holds ito on the Laptop/Monitor seems to be too large for no reason. I would've made it smaller from a better material, for the price that it is being sold they should've "gone the extra mile".Carl Zeiss optics are supposedly what makes a difference.However the lens is the same size as all the regular webcams.I would've thought that Zeiss optics would use a larger and brighted high index lenses that they are known for, to allow more light to get in and improve image quality as additional benefit.Not so. Well the lens does seem to let more light through then the plastics.but most of the improvements seems to come from post processing of the captured image(this is a speculation at this point, I have not done any professional testing to verify my inference).

I purchased this to replace my 16-35mm L lens that cost about twice as much. I am very pleased with the clarity this lens provides... especially for the price!

This UV filter has been a great addition to my Tamron 35mm for my sony. This filter is definitely more of a protector than a modifier at least in my use case, it helps to protect the exposed focusing mechanism of the lens and makes sure that no dust or particulates get into the lens. Overall I would say that this is a great filter to put on any lens as it adds a barrier between the front element and the world, and I didn't notice any negative effects on image quality by having this filter on the lens.

I finally got this super fast 35mm lens after years on the original EF (nifty) 50mm f1.8 and I'm blown away. The colors seem to have a cooler tone than with my 70-200 f4L IS or 16-35 f4L IS (possibly that Blue Refractive optical element) but this is preferable to me. I often regret stopping this lens down in any other setting besides direct sunlight because it is super sharp corner to corner at f1.4 and everything is in focus when focused near infinity. The closer you get to your subject at f1.4, the more your photo becomes an elegant work of art with bokeh that just melts away but yields a nice wide angle view of the subjects environment. Fast enough to catch that split second smile on your significant other's face and give them the separation from the background that just makes them pop. People become electrifying when captured with this lens. Every photo makes me smile with joy and love. If you are a photographer and you love capturing beauty in a setting, you need this lens. Don't fool yourself by saying you can't afford it, sell all your slow f4 zooms and maybe a toe to capture the world through 35mm.

I've used this with my 35mm f/1.4 E-Mount . By far, this polarizer has not came off my lens when i took it out for travelling to Hawaii. It gave my shots more contrast, darkens the highlights to the point where I can use the image and of course, see through reflections. As a polarizer, it does what most polarizers do, I definitely would recommend this filter!Highlights:- Tiffen helps with maintaining the sharpness- Blocks reflections- Ups the contrasts in your shots and reduces highlights

I really like this product, actually this is my 2nd order fr them. Unfortunately I lost the cp mount of my 1st tripod and I’m just wondering If I can just buy the cp mount from them. Is it possible to contact them for just extra cp mount?Thanks.

you get what you paid for. It's not a product like B&W.Wonderful for sony zeiss 55 1.8. I touched the glassed in the lens and made some scratch and then decide to get this one. This filter can really protect the lens from unintentional touch.

35mm focal length on full frame-- not the most extreme wide angle nor a crazy long focal length that isolates your subject and gets rid of everything else. Just... normal-ish. Easier to use for walk around stuff than 50mm in my experience, but depending on your preferences ymmv.Image stabilized... but in my experience it hasn't made enough of a difference to change my shooting habits.f/1.8, usable. Not gonna blur the heck out of everything on a lens this wide but it allows shooting in pretty dark conditions.Decently sharp, not incredibly so.SLOW autofocus, but it works.Reasonably small.Good close focusing distance.It all adds up to a lens that doesn't particularly excite me to use, but one that I could leave on my camera all the time and not be disappointed by. It just sorta works and the only thing that regularly gets in the way is the slow autofocus motor.Would highly recommend a 3rd party lens hood for this, the Canon one isn't anywhere near as big as a 35mm can benefit from.
