Each and every time I mount this lens on my 1DS mark II camera, I'm falling in love with Photography again. This Lens is super fast auto focus and deliver sharp and crispy images quality even at wide open F/2.8 the IS functioning is all about for my handheld shooting on location without tripod, it works effectively and reliable. I can compare and rate this lens almost perfect like my Canon 85mm F/1.2L but 70-200 IS USM is faster autofocus. With the zoom lens like this shooting on Manual mode is my favorite cause I can make the most beautiful pictures out of this lens.It wasn't true as some previous review said there is a problem with many lenses with serial number of UT08XX or earlier. Honestly! Mine is UT04XX but it perfect and I will keep it till my last breath.

This is very nice, high-quality filter and it fit my Lumix FZ80 lens perfectly.

Perfect! Bought this for the 25mm f1.7 lumix lens, works flawlessly. Really impressed with GOBE ND filters

Hey, I'm PercyI'm a YouTuber (Gogglez Enraged) that does reviews, tips, recommendations, and top gears to get.Build quality of the 50 f/1.8 is very cheap (as you might expect). This lens feels more like a toy than a piece of optics. It utilizes plastic construction right down to the lens mount (the lenses are glass of course). This light material combined with the small size (2.7" x 1.6"/68.2mm x 41.0mm - WxL) puts this lens in the featherweight class - 4.6 oz (130g). The 50 f/1.8 is currently Canon's lightest. It was also Canon's shortest EOS-mount lens until the Canon EF 40mm f/2.8 STM Lens was introduced. The Canon EF 50mm f/1.8 II Lens delivers very sharp images as inexpensively as Canon lenses get.The 50 f/1./8 bears a plastic lens mount. Considering how light the 50 f/1.8 II lens is, the plastic lens mount seems adequate from a strength perspective. You might get more wear than you wish if you are changing the lens frequently.Autofocus is driven by a micro motor. Focus speed is not stellar, but fine in good light with subjects that are not moving too quickly. The 50 f/1.8 II is one of Canon's louder/buzzier lenses - you know when it is focusing. But this is not a wildlife lens - and the noise probably won't bother most people. I suppose a positive aspect of the sound is that you know when it is working - and when it is finished working - when focus is locked. FTM (Full Time Manual) focusing is not included. The 50 f/1.8 extends up to 5/16" during focusing - the very small 52mm filter does not rotate.All in all, I truly enjoy using this lens for my B-roll for my Youtube channel and the webpage. As well as having those awesome blur shot background. i highly recommend purchase this lens cause its inexpensive and a good lens to have around because of its size and the picture quality.

This is a very good quality lens cap however it doesn’t fit my Canon Powershot S5 IS. I should have did my research a little more. I would love to keep it but I’ll rather send it back so someone else could benefit from it.

Great lens! I have it on a Panasonic Lumix G7 with speed booster. There is a big difference between this and the kit lens. It is a little noisy during focusing, but I do not plan on using this lens during video mode.

When I read the news of Canon releasing a new Mark II version of this lens the first thought that came to my mind was why? Has Canon lost its mind? Why would you mess around with a lens that has become a staple of nearly every professional Canon user in the world? Since this lens was released in September of 2001 it has earned a reputation as being one of the most rugged and sharpest lenses of its kind. Professional photographer and photo equipment reviewer Ken Rockwell, for example, borrowed this lens from a friend to test who had dropped it off an elephant to the cobblestones nine feet below while shooting in India. Even with that event in its history Ken gave it a stunningly positive review! Many of the most famous photos taken in the last nine years were taken with this lens, including many of the photos that appear in Canon's own sales brochures. In the lens life cycle, if such a thing exists, this lens is hardly an old timer at nine years old. With its proven powerful robust image stabilizer, legendarily sharpness, and tank-like build, one cannot help wonder what the motivation for fixing something that's not broke is. I think the real motivation was keeping "pace" with Nikon and raising prices.Canon is seen more and more as falling behind its nemesis Nikon. With the recent release of Nikon's VR II vibration reduction which supposedly can work up to four stops, Canon had to fire back with a "new" version of the image stabilizer on its own lenses. Thus IS II was born. Needless to say, the new Nikon 70-200 lens retails for over (...) on Amazon as opposed to this "old" Canon lens which sells for about (...). It's expected that new Canon 70-200 2.8L IS II will retail for at least (...) if not more. Is the new lens really worth (...) more than the old lens still being sold? I own this "old" model now for about six months and the only way I can see improvement is if somehow Canon could recreate this same lens, ruggedness and all, at half the weight. Now that would be something worth paying (...) or more for! In reality, the new model will actually weigh 20 grams more than the "old" model. So much for progress!I have shot indoor and outdoor shots both hand held and with my Bogen automatic mono-pod with this lens. In both cases the results have been nothing short of amazing. Clear sharp images almost every time with magnificent color and superb brokeh (blur quality). The image stabilization is first rate and runs hard and strong. Don't be fooled into saving money buying the other versions of this lens. If you ever expect to be free from using a flash and get great results in reasonable natural lighting, this is the lens to buy. If you can't afford to buy this lens then save up for it. If you compromise you may be sorry later.I believe that any changes Canon has made to the new lens will largely be undetectable by professional and amateur photographers alike. The only exception to this is the added weight, increased price, and the very slight ability of the new model to focus closer (about 8"). It's also hard to see how the current powerful image stabilization could be made much better. At some point it all becomes a matter of subject movement and no stabilization system can deal with that other than using higher shutter speeds. That said, the more important question to ask is whether Canon produced a "better" lens at all? Currently we have no test reviews to look at and it is entirely possible that the new lens may actually under perform this "old model". We just don't know at the moment. For my money I would grab this "old" model while you can. Not only is there hardly any risk, but in all likely-hood the after market value of this lens may soon rise.MY UPDATED COMMENTS: Despite some new positive reviews on the new lens, I still doubt that most will notice much of a difference between the new and the old lenses unless they really blow up the image. The old lens produced images that graced some of the top publications worldwide for the last 10 years with nothing but praise. Canon has effectively fooled you all to push though a huge price increase never before seen for an upgrade of the same type lens. It seems the consumer is once again the victim and they don't even realize it!

[For unclear reasons this review and all others for the Mark I lens have disappeared, I'm re-posting mine]I purchased this lens about 8 months ago as my first "L" glass - since then I have added the 24-70 f2.8 Canon (without IS) to complete the range 24-200 mm at f2.8. I really can't say enough good things about this lens, though in retrospect I might have bought the 24-70 first as it is a bit more versatile. The build quality is terrific and the IS is VERY helpful especially at the longer focal lengths. The f2.8 also allows you to get a teleconverter to double it to 400 mm (though I don't have that as of yet). Though I'm sure the f4.0 is a great lens, the extra stops on this lens allows you to take existing light pictures in amazingly dim conditions. One of my primary uses for this lens will be school programs as it will allow pictures without flash in many of those conditions (especially after a body upgrade to push the ISO a bit - but that's another story). This is the type of purchase that changes the level of photography you are capable of. If you can afford it, you will be very pleased with the results and will have a lens that will likely be a mainstay of your equipment likely for decades. Other reviews have noted that this lens turns heads / looks impressive and that is true though I don't think that is a reason to get it - the quality of the pictures is the big payoff.I decided to write this review after hearing that they are coming out with the Mark II version of this lens with "fourth generation" IS and an additional set of lens elements that are supposed to further improve the picture quality. Honestly, I don't see how further improvement in image quality is possible after seeing what this bad boy can do. The modified IS is supposed to allow for an extra stop or two as a hand-held lens which is nice if you are really shaky but I doubt will really improve things much - of course IS is really a "portable tripod" and does not allow additional stops for subjects in motion. IMHO the IS on this lens is more than sufficient for the task and no modification is needed. As I understand it, the Mk II may be priced around $2400. I hope that they keep producing this "Mk I" lens since my advice would be to buy this one and use the money saved perhaps for a prime lens or the aforementioned teleconverter.ADDENDUM: Indeed, the Mark II came out at a pricey $2500. The first 2 reviews for that glass are reportedly people who compare the lenses directly which I cannot do, of course. If I had it to do over again I would still buy this one and perhaps use the leftover funds to upgrade to a T2i body.
