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

L'ho appena provato sul nuovo obiettivo Canon 100-400: le immagini sono molto nitide, non si avverte alcuna riduzione della luminosità o aberrazione cromatica, senza fastidiose dominanze

I shoot with a Canon 20D and before purchasing this lens, used the Canon EF 75-300mm f/4.5-5.6 III USM lens. I've always noticed the limitations of this lens when shooting amateur softball. I reviewed the lens lineup at the Canon website and decided on purchasing the Canon EF 100-400mm f/4.5-5.6L USM Lens. The 100-400mm is a great lens, but it can be a little soft. For that reason I decided to add the Canon EF 70-200mm 2.8/f IS USM telephoto zoom lens to my lens collection.As an L lens, there are numerous features and is manufactured with high quality materials and a higher level of dust and moisture resistance compared to the standard line of lenses. This pro quality lens is meant for serious photographers with high demands of their equipment. The construction is sturdy and consists of 23 elements in 18 groups. The four Super UD-glass elements largely eliminate the secondary spectrum reducing residual chromatic aberration. An improved 8-blade circular aperture offers a more pleasing out-of-focus image. The Canon EF 70-200mm lens weighs in at about 3.24 lbs/1,470 g, and a minimal focusing distance of 4.3 ft/1.3 m. The front thread accepts 77mm filters, be sure to get a 

good quality UV haze filter









to protect the front lens element. This lens is compatible with the 

1.4x II









 and 

2X II









 telephoto extenders.Being white, this lens looks out of place, but helps it stay cool when shooting out in the sun. Some people are concerned that being white, it attracts attention to criminals. From my experience, my 20D attracts attention regardless of what lens I put on it. In addition, I most likely have a camera bag and tripod/monopod with me to further attract attention. I personally doubt a thief looking for something to steal is taking the time to evaluate the cost of the item and are more concerned with the ease of taking something they can unload. I try to make things difficult for would be thieves and have my equipment insured as a back up.The dual IS system has two modes. Mode 1 is for stationary subjects while mode two is for moving subjects. It is recommended that the IS function is not used while using a tripod; however I have successfully used this feature while on my monopod. The IS helps to eliminate camera shake and helps stabilize the lens when shooting from a moving vehicle or in low light situations. While there are limitations to what the IS can do, it can give you a few extra stops. Just keep in mind, the IS attempts to eliminate camera movement, not the movement of the subject being photographed.This lens permits for auto or manual focus depending on how the switch is set. There is also a switch to shift from a 1.4m/4.6ft to infinity or 2.5m/8.2ft to infinity.Included with this lens are the tripod mount, lens hood, and storage case. The tripod mount is the best option to use when mounting to a tripod, helping to maintain balance. Mounting the camera instead creates an unbalanced set up that may topple over. The case is a 

zippered soft case (LZ1324)









 that can also be purchased separately. The 

lens hood (ET-86)









 is used to reduce lens flare and can protect the front element in certain situations. Often times, Amazon recommends purchasing the lens case and hood, however they are normally included with the lens.The Canon EF 70-200mm is such an awesome lens, it almost fails to compare to the 

Canon EF 75-300mm f/4-5.6 III USM telephoto zoom









. The 

EF 100-400mm f4.5-5.6L IS USM telephoto zoom lens









 is a well used option for me, but the clarity and sharpness of the 70-200mm IS lens is more refined. I doubt the 100-400mm lens will be replaced by this lens as a favorite. I find the push/pull focusing of the 100-400mm lens to be a benefit that the 70-200mm cannot replace. This lens can be used for portraits, landscape, sports or as a general walk about lens. The f/2.8L combined with the IS makes this lens a good option for certain low light situations. The features add creative versatility. The Canon EF 70-200mm IS lens comes at a price, but it is worth every bit of it.PROS:Incredible clarity and sharpnessQuiet and quick auto-focusFeatures add creative versatilityDual IS systemCONS:Heavy and bulky (This should be expected with these types of lenses)

What can I say! It's a Canon body cap that will fit any canon camera with EF anf EF-S mount, doesn't matter if it's a full frame, APS-C, or film. In other words, if your camera was made in the last 30 years, this cap will fit!

I've used my EF 100-400 with an RF adapter. It's good but as someone older, this RF lens is light, compact, and is optically sound for my purposes. I also own a 150-600 Sigma which usually needs a pod to hold steady and I've missed more shots than I've captured with it. This RF 100-400 is great for me; it so easy to pan while shooting birds in flight!

Initially I wanted the official canon adapter, however these were out of stock with no date for restocking so I bought this instead. Although I can’t compare this generic item to the branded Canon adapter, I have to say that so far I have been really impressed with what it does. All my EF lenses (Canon 100-400l mk2, Canon 100 macro, Sigma 150-600, Sigma 150 macro) work perfectly with all functions operating as I would expect. At at least half the price of the Canon adapter, I have no hesitation in recommending this item.

I’ve been known to be a Canon L lens snob. I picked up this lens for my daughter’s kit but decided to test it during a local soccer game. Besides losing a 100mm of range from my Canon 100-400 L II lens, I noticed no significant visual difference in the photos compared to the significantly more expensive L. In the end, I post process every pic anyway so they only thing that matters to me is sharpness, focus speed and accuracy. This little lens does the trick in all those areas and is great for video. In fact, I’m keeping it and selling the 100-400. It is a very nice lens and I highly recommend it.

Great canon product. It works well with my EF 70-200, EF 300 and EF 400.
