The product works good with my Canon mirrorless camera with Sigma Ef 18-250mm lens with all functions. But the cost of the product is only Rs.7500 in canon showroom. This product is in great demand and not in stock so they are selling at an extreme price. If you can wait just place an order with canon and get it at a lower price

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.

This lens is one of (if not THE) best lens Canon makes, period. It is the premier "sports lens" in the industry, and it has that title for several reasons:1.) BUILD QUALITY: It's built like a tank.2.) WEATHER SEALING: couple with a 1 series body, as soon as it starts raining, everyone else will be scrambling to keep their cameras dry.3.) SUPERIOR OPTICS: color and contrast from this lens are excellent.4.) IS: I bought this lens because of the IS.My former 70-200 lens was the Sigma 70-200 f/2.8 HSM. I'm not going to sit here and lie saying the Canon completely blows the Sigma away- it simply doesn't. The Sigma is a fine lens. It is also built like a tank, the HSM is almost (when I say almost, I mean by milliseconds- ie barely noticeable)as fast, and the colors and contrast are superb- almost indistinguishable from an L lens. There are a lot of "almosts" in this paragraph, I know. The Sigma is "almost" perfect, the Canon IS PERFECT. If you are willing to pay the substantial price difference for perfection, more power to you.The main reason I purchased this lens was not because it was white, not because it has a red ring, and not because it's a Canon. I bought it for the IS. I am a sports shooter and I found myself limited in the shutter speed I was able to use with the Sigma. I am a big proponent of the 1/focal length (x 1.6 on my 30D) rule. At 200mm, I would need a shutter speed of at least 1/320 to prevent camera shake. When using flash, I would have to use HSS for the flash to work at that shuttter speed. HSS significantly cuts down on flash output. I would rather use my cameras maximum x-sync speed (1/250) most of the time. This is where IS comes in handy for me. With the Sigma at 200mm/ 1/250 I would get blurry shots, with the Canon using the IS I'm safe. I can even go several stops slower than 1/250 if I desire. The IS is fantastic and is definitely worth the extra $$$.

This adapter did the job! I can now use all my Canon, Tamron and Sigma lenses on my new Canon m50.

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.

I bought this product because my 580EX2 started to act up.Not having the funds to afford another 580EX2 or the 600EX-RT at this time, I did my research and decided to buy the Sigma EF-610 DG SUPER.I read the reviews about how cheap the flash feels.I beg to differ, it looks and feel fine to me. We have so grown to accept Canon products as a standard (with good reason), so if it does not look or feel like Canon it is no good. The plastic battery cover was another problem to other reviewers, for me I am no less confident of the durability of this cover than I am of the battery cover on my EOS Canon 7D.I do not buy a speedlight to drop it on the ground from 8 feet up so whether or not it can stand up to the shock of being dropped on concrete from 8 feet up was not a concern I had before purchasing it. My major concern was if this product would trigger my other canon speedlights if I used it as a master. Well it does trigger all of them, the 420ex, the 550ex and the 580ex2.The menu on the back is a no brainer, one does not even have to consult the manual.It has all the power I need. It compares favourably with the 580EX2 and is far more powerful than the 430EX2.The exposures are spot on, equal to my 580EX2. If I am to fault the Sigma, the flash gun head cannot be tilted up and down in increments like the Canon. It has an angle where it clicks in place when adjusted upwards and will fall back down if it is not set at that particular angle. One has to consider cost when buying a product. For the price it is an excellent product. I would still buy it even if it cost a bit more (by the way I am a Canon Purist). but there are times when an immediate need has to be fulfilled. I am happy with my purchase. I cannot yet comment on its durability yet. More anon.

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!
