I am not a professional one but the circular polarizer is a good quality for the price. I use it with my canon 40D on a 17-85mm lens.However, the box wasn't sealed and I didn't like it because it seemed as it was already used.

I've had the Canon 50mm 1.4, and now this lens. and I can honestly say this one is better. This one focuses fast, it's small, looks great, is bitingly sharp, even wide open. and can easily be used professionally. I bought this just to have a lens, any lens on the front of my Canon 6D, but it's amazing. I'll be keeping this one. My 50mm 1.4 USM lens had major, major backfocusing problems, which I've read is not uncommon for that lens. I ended up selling it, even though it was a sharp lens. The focusing was terrible. This one is dead on, sharp, and contrasty. It's also probably the cheapest lens you can buy. If shot wide open, it's VERY sharp in the center, and there is definitely some slight vignetting (although it looks good in portraits, which is presumably what you'd be shooting wide open), and a "swirly" quality to the bokeh. I was taken aback by it, but it's cool. Almost Lensbaby-ish. Definitely get this lens!!!

Professional reviewers of the Canon M6 Mark II bemoan the lack of quality native lens. Get over it. Circular file those kit zoom lens like the ones handed out in Canon’s press preview events. (I have given away one M50 camera body and kit zoom lens with another giveaway to come.)Sigma has released three quality EF-M fast prime lens. I have been using both the 16 mm f/1.4 (24 mm equivalent focal length for full sensor) and 56 mm f/1.4 (84 mm). Along with Canon’s 32 mm f/1.4 (51 mm), these are excellent lenses. The advantage of the Mark II higher resolution sensor (compared to the M50) and good prime glass can be seen in 11x17 and 13x19 prints. Hopefully, Canon will release a quality EF-M zoom lens in the near future.Why spend thousands on a prosumer crop sensor camera? Two reasons. First, you avoid the greater bulk and weight of full sensor camera body and glass. Second, the Canon M6 Mark II is an excellent camera for concert photography without a photo pass. It passes for an inexpensive compact camera. Buy a good seat within reach of the 32 mm or 56 mm lens. No EVF or zoom lens to call attention. Elevate the camera slightly to clear the heads of those in front of you. Limit shooting time and dim the LCD display to be courteous to those behind you. The wide shots and medium crops will be excellent to print and share with family and friends. Leave the commercial stuff to the pros.2/4/2020 - just returned from a 10 day vacation in US Virgin Islands and British Virgin Islands. The camera and lens got a workout in all conditions, including pouring rain. The Canon 32 mm f/1.4 was the sharpest lens and produced the best photos. After many hours of Lightroom processing and review, I believe the Canon lens outperformed the Sigma 16 mm f/1.4 which excelled in indoor photos, such as the one of the St. Thomas synagogue. The Sigma 56 mm f/1.4 did a nice job as well.I chose to shoot most outdoor shots with an aperture of + or - f/5.0 and a shutter speed of 1/2000th - 1/3200th of a second. Setting my focus point a third or so into the frame, I was able to obtain pretty sharp focus foreground and background. (I am just an amateur. Please forgive my lack of mastery of technical terms.) For what is it worth, I felt the camera struggled a bit with dynamic range, especially shooting the Baths in Virgin Gorda where giant boulders blocked the sunlight and created deep shadows. I was only partially able to bring up the shadows in Lightroom. This was one of those times in the trip (there were others) that I wished I had brought along a full-frame camera, like the impressive Nikon kits lugged by 2 German visitors wadding through the Baths (don't slip).Now a downside or two to this camera. The touch shutter constantly defaults to ENABLE mode, despite constant disabling in the menu. This produces a lot of wasted shots and a focus point on the display that moves around all over the place. And, the EVF stayed in my bag nearly the entire trip. (I used flash on several occasions and had to remove the EVF each time to mount a flash or remote trigger.) It is just easier to compose the shots using the display. I turned the display brightness to maximum, and could make out the display even in the intense sun of the Baths. Seriously consider buying this camera as a body only without the EVF and mediocre kit zoom lens. I doubled down and ordered a second body.

For a relatively cheap tripod, you can't go wrong. I use it with a Canon 5d, in a cage, with a 85mm, follow focus, LCD monitor, etc... holds up like a champ.

Fits right in to my Canon 17-85mm IS USM lens. Does what its supposed to do without any degradation in image quality.

update:using the eos m3 i compared the images from this lens to a few i just took with the older canon 85mm 1.8 lens. even though the 85mm cost like nearly 3 times more. the 50mm 1.8 STM in my opinion had both sharper image quality and much better coloring. side by side the 85mm 1.8 seemed washed out, so much that i went back to redo a set a photos i just took with the 50mm 1.8 instead. If you have a newer canon digital camera like the eos m3 , i would highly recommend the 50mm 1.8 , not only will you save money but overall much better image quality and usability as you dont have to step back so far, but still looking very nice![older review:]I was a bit hesitent to buy this lens as i already had the 50mm 1.4 USM which is a great lens but the one i had started having some sluggish autofocusing issues and in some points simply would not autofocus right (more so if the image was fully blurry and you were trying to focus on something sometimes it just would not focus) But i just bought the Canon EOS M3 (on ebay) and decided since it was a nicer faster camera then the M1 maybe it would be worth trying out the 50mm 1.8 STM as i hear it was faster in focusing and lighter weight too and even a bit sharper wide open. After tryng it out i must say it really is very nice VERY fast autofocus compared to the 50mm 1.4 in my opinion. Sharp and produces nice blurry backgrounds. Does not feel cheap. I mean it def doesnt feel "pro like" BUT it doesnt feel like a toy in my opinion just about the "Right" quality for something like this.For non full frame cameras this likely is the BEST Option you can get for starting out with wanting to take more photos of people. as cropped sensors make it more like a 85mm lens so you get a nice flattened image of the person without having to stand too far back (which can be better in many situations).I think after years of trying diffrent things ive found the best solution for photos of people is this lens + the canon eos m3 (with adapter) so that you have a nice compatish camera that is not too heavy or bulky and very fast and sharp!My issue with the 50mm 1.4 was that sometimes inside it didnt "grab" the image good or it took too long or it wasnt quite as sharp or whatever. Much like the EOS-M 22mm 2.0 lens which is a great value for the price, this is as well (if not more so since you really can use this better for pictures of people).If your a bit new to photography and want to take images to stand out vs all these "cell phone selfies" Just get one of these you'll be amazed at the quality and the possibilities it opens up for a great build and price! I liked it so much i put the box for the 50mm 1.4 in my drawer and proudly put the box for the 50mm 1.8 STM on my dresser because i think for now ive found it is the BEST Lens canon has for the price and what it can do to make great photos of people. Cant wait to use it even more!

Obviously, I would love to own the Canon 50mm 1.2 L lens. But I mean, who wouldn't? I love this lens, I was debating between this and the 85mm for some time, but I chose to buy the 85mm first. I've had it for a while before I bought this 50mm and I can say I wish I had bought this first. It's more versatile, and as an added bonus, its LIGHT! I finally feel comfortable taking my good camera out and about now (well mostly, I'm still a little chicken) I took it to the Labor Day parade, and it was awesome! I was debating between this and the 1.4 and this lens had better reviews and being new to the photography world, I couldn't really find a difference in the lenses other than the f/stop. So in my opinion, this one is great!

I own the Canon EF 500mm f/4L IS Lens. Not the version II. The original lens. I also own the 1.4x teleconverter version 1 also. I bought this for bird photography because the 1.4x was not quite close enough to suit me on the smaller birds. My blind is set up at a fixed distance so it's pretty predictable how much telephoto power I will need. I am shooting with at Canon 7D Mark II. The effective focal length with this converter on a 1.6 crop camera is 1600mm. Very, very nice.Unlike other reviewers I found this teleconverter to be the equal of the 1.4x (at least version 1). I can't imagine it being much sharper. Please see the full frame dove shot and the 1to1 crop.You can see the full frame uncropped full resolution image at flickr.com/photos/davidpitts/18102024249/sizes/lIf you need the reach and you have a Canon long prime lens, I'm not sure how you can go wrong.I should add here that I spent considerable time working with Canon's AF Microadjust feature for this combination of 2x converter and lens. It made a significant difference in sharpness. If you have this feature on your camera you should do this for every lens.
