Perfect with an adapter for my Canon SX40. Thanks!

Used in conjunction with an adapter on a canon M 50. Ace.

I got this lens a while a go...the first copy was defected but the second one was the right one....is very sharp considering that is not L series...but the focusing system is very fast...I can focus almost instantaneously...is fantastic considering the fact that is 4-5.6 lens....for everyday shots is very good...I was debating between the version of 70-300 L and this one and I'm glad that that i choose this one...considering the price.... now compared to the 70-300 Nikon version is faster and sharper without doubts,, i have Nikon and canon full frames and regarding to the 70-300 range...this canon beat the Nikon one....for sure...

nice fit and works great with both my Canon and my Nikon

Canon and Nikon need to take notice before of the word value

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!

The canon adapter has been unavailable for a while, so I thought I'd try this one out so I could actually use my new R5. So far it works flawlessly!

Very high quality build no complaints protects dji drone Z7 nikon camera accessories and a lot more very pleased
