Review on Canon EF 100-400mm f/4.5-5.6L IS II USM Lens - Lens Only for Improved SEO by Patrick Brinson

This is my first L lens. I recently upgraded the camera body to a 7D Mark II to capture the action at my kids' soccer games. The kit lens that comes with the camera (EF-S 18-135mm STM) has a limited focal length, so I need a longer telephoto lens. I aimed the L lens and decided I would need a focal length longer than 200mm and zoomed in to 28-300L, 70-300L and 100-400L (mark i). I quickly threw away the first and third because of the two-stroke, and the second for its price and drive is almost ready to buy, albeit with some hesitation due to the lack of a tripod mount and incompatibility with Canon teleconverters when I saw all the new 100's -400L (Mark II). Reviews of the Revain and B&H are generally very positive and the new technology in the lens feels overwhelming. So, after a quick self-assessment of the costs and benefits, I made a purchase from Revain. The lens arrived a few days ago; Delivery was quick - thanks Revain Prime. I have yet to get it outside and film my kids' games, so I can't comment on how it performs in the 'real world' - I'll try to update this review when more data becomes available. However, I can say something cosmetic about this lens. First, it's hard. At over 3.5 pounds, this lens is a monster. Mounted on a 7D Mark II, this combo weighs over 5 pounds. I'm still improving my muscle memory (and it's getting better every day), but I can tell you that hanging this thing around your neck is certainly not a pleasant experience. However, the handheld shooting position isn't actually that bad; I don't think I need a mono/tripod for soccer shootouts. I'll probably carry my camera with the lens on my shoulder when I'm moving around during a game. Secondly, the image stabilizer makes a distinctive clicking sound when switching on and off in autofocus mode. It's a bit annoying compared to the almost silent operation of the STM lens, but I think I'll have to get used to it. In live view, the sound of the IS motor is not audible, but the movement of the lens elements is audible when zooming. I hope this doesn't ruin the video recording. Third, there is a small hole on the hood that can be used to control a polarizing filter. Sometimes I found this little "window" accidentally opened too easily; So you have to make sure that it is closed. The overall build quality, feel and image quality captured on some of the low-light test shots look very good. Can't wait to pull it out to see its full potential and see what and how that gorgeous white lens reveals. Outdoor sport activities for children. In good light (sunny skies) the lens (along with my 7D Mark II, set manually at 1/1000, widest aperture at equivalent focal length) delivers sharp images, vivid colors and high quality (ISO below 400). However, on a cloudy sky setting, with the same shutter speed and aperture, the ISO images consistently exceeded 2000 and sometimes 4000. Image quality is significantly less impressive than below ISO 400 shot in bright sunlight. Well, you could argue that this is the 7D Mark II's sensor. But I think that the maximum aperture f4.5-5.6 of the lens also plays a role. Hence the conclusion: the lens is ideal for sports in good light or slow-moving or stationary objects in less than ideal light; but can extend the limits of low-light activities (e.g. on sports fields or on stage).
