Canon RF100-400mm F5.6-8 is USM Black

I bought this lens to go with my new Canon R7. Or maybe I bought the R7 to go with this lens? I really wanted a lighter weight lens and camera for carrying with me when hiking or birding. My 6d / 100-400mm F4-5.6 IS L (Mark 1) was too heavy to carry around my neck for hours. I got a Sony RX10 mark IV bridge camera which was a great size and weight, but the picture quality was not as good as I wanted. This lens and body combo is hopefully the answer to my problems.The lens itself is pretty impressive in terms of its length and weight. Sure, I wish it were shorter, but for 400mm, I can't really complain. I also wish it had a wider aperture, but for the lower price and weight, that is obviously the compromise you have to make. The sensor noise performance of the R7 eliminates some of the downside of the slow lens, but it can't help create the nice background blur that a fast lens will have.The image stabilization combo of the lens and body works exceptionally well. I have been getting sharp shots at 400mm with 1/250s handheld with my shaky hands. Images look crisp to me and autofocus is very fast and quiet.One thing I have not gotten used to is the zoom ring works backwards from every other lens I have. Maybe someday I will get used to it, but for now, every time I try to use it I start with rotating it the wrong way. On the plus side, there is no zoom creep when I am walking around with this lens around my neck. There is a lock where you can fix it at 100mm, but I have never had to use it.I am a little disappointed there is no weather sealing on this lens. I'd have paid a little more to have some basic weather sealing on it as I don't want to have to worry about using it in mist or rain.I'm not taking any stars off for those items that disappoint me about this lens as they are either compromises for size and weight, or were known limitations when I bought the lens and not a surprise. Overall, 5 stars as I am very happy carrying this lens around for hours taking bird photos.

Is it perfect? Maybe maybe not but it more than meets my needs and has great reach at a fantastic price. I waffled on buying this initially but have zero regrets after buying it.

This is so fun to use. I’m a very beginner but knew I wanted some extra reach over the kit lens on my r6 mk ii. I shot some wildlife and my best girl pup. I had a blast using this. I think the image quality is just fine. I had zero problems with the higher f stops. I’m sure someone more experienced than me can take a lot better pictures than me with this lens, but I will say I am very happy with the quality. I tried it on the full moon as well. Not exactly telescope level but it’s pretty cool. Had to crop in on the moon and you know what that means. Get this lens and don’t worry that you didn’t pay like $2000 more for some white lens. Just have fun.

Great choice!

Great lens for shooting sports! I've used it for wrestling and track so far! Can't wait to use it for Football

As advertised. Best quality and Securely packaged.Thank you for your service and business.

Is it normal that my canon rf 100-400mm lens moves inside? I wanna say its the barrel inside that moves when i shake the lens side to side a little bit

I'm quite happy with the lens. It has good zoom range and, unless you're in extremely low light, it will serve you well.
