Pros: Lightweight, good build quality. Good sharpness (but only up to certain focal lengths)

Cons: Loss of sharpness at maximum focal length

Opinion: A lens that I bought for my son's setup and therefore in combination with his mirrorless Canon eos R10 obviously with adapter ring. Aesthetically very beautiful, comfortable lock of the barrel extension, excellent IS, very "nice" upper liquid crystal display (although not very useful in my opinion), good general handling. As for the accuracy of the detail, this is present as long as the subject is not too far away and/or that the focal length does not need to be extended to the maximum. At least this is what we were able to find in combination with the R10. I recommend it exclusively on the reflex system as in my opinion on more modern systems it loses a bit of goodness. I'm replacing it with the more modern RF 100-400 IS to get a few more mm that in naturalistic is always useful and in the hope of having a little more sharpness at all focal lengths.

Pros: Sharpness, stabilization, built with care.

Cons: For the moment not taken for granted.

Opinion: I use this telephoto zoom on the Canon EOS R, replacing the disappointing RF 100-400 that I had for a couple of years or so. The difference and versatility of use in comparison is quite obvious. This 70-300 is also great in portraiture as well as landscapes. It is always sharp, unlike the RF 100-400, especially when used to shoot landscapes/objects/subjects at greater distances, in the same light conditions, where it always shows good/excellent sharpness. Even when used with adapter, it maintains a good balance and lightness. Happy with the exchange that I would do a hundred times. For me it deserves a full 9, unlike the RF 100-40 which, for my taste, bordered on sufficiency and a mediocre value for money.

Pros: Compact, lightweight, sharp, excellent autofocus and stabilizer performance.

Cons: Not very intuitive distance scale display, focus that can only be changed when the camera body is powered.

Opinion: Among the many 70-300s I've tried (old Canon, stabilized or not, Sigma, Tamron...) it is without a doubt the best quality as far as image quality is concerned. Compact and solid construction, not too heavy, very efficient stabilizer, fast and silent focusing although unfortunately not very comfortable in some situations since it is electro assisted. Ideal for completing a lightweight and efficient setup.

Pros: Lightweight, stabilized, fast and quiet autofocus and compatible with focal length duplicator

Cons: mine sometimes at 300mm you have to wake up the autofocus, closing the focal length a bit ..

Opinion: Rather bright, contained and light optics, it has a precise and fast autofocus. which in case of low light becomes less fast. But I think almost every lens has this problem.. 9 slats and a nice blur at TA . The quality of the lenses is truly remarkable. I have an old canon ef 100 400 is USM L (first type) and it doesn't have the sharpness of this 70 300.. I'm not crazy about the digital display. while stabilization is very effective ! It is not tropicalized and dust has an easy life to enter, it takes care.

Pros: Value for money tending to infinity

Cons: In low light, autofocus performance decreases in terms of speed. Expensive but beautiful original lens hood.

Opinion: Objective, in my humble opinion, simply extraordinary! At all focal lengths and at all distances of MAF, even if at infinity it drops a little. Remarkable speed and accuracy of MAF. Absolute silence of both the autofocus and the stabilizer. Excellent assemblies, externally in plastic materials but of high quality. I've owned it for a few years now and never disappointed.
