Pros: Lightweight for the focal length, good quality, focusing speed.

Cons: At the moment nothing

Opinion: Bought with R8 matching, responsive and photo quality with detail. Few "frills" for the choice buttons. Purchased for wildlife photos, I was a bit skeptical of F9. But I must say that stabilization helps a lot. I recently switched to R6MKIII, with the same lens, the quality of the shot (also thanks to the FF R6MKIII), is on another planet.

Pros: All

Cons: Don't get it before

Opinion: I was very skeptical about this lens, I thought it was the same as the 100-500mm quality optics but dark..... but after some advice including Vito and reading many comments on juza, I decided to take it. Found at a good price New on Reflestore. What can I say It was love right from the start, excellent build and optical quality. On R5 it is well balanced, the weight is right .... great lens .... I am very satisfied . It only has two Af/MF switch and on/off stabilizer overall I don't regret the various switches found in L lenses. The various AF configurations dedicated to the R5 with this lens are phenomenal.

Pros: Great focus, excellent stabilization

Cons: Aberration at TA - carrying bag not present

Opinion: Purchased for lunar alignments and landscape photography in general, I'm happy with the lens which is worth the cost. It is certainly not very handy, given the weight and the focal length, but it is an 800mm, it also seems evident to me. The lens is extremely sharp even at full aperture. A defect, in my opinion, is a certain chromatic aberration found at 800 mm, not correctable directly in ACR but "fine" in Photoshop; probably being purchased primarily by "avifaunists" I will also be the only one to have noticed it, using it at night on subjects with strong light contrasts. The stabilization system is very effective, I was able to shoot the moon handheld in conditions where I would normally not be able except on a tripod. The construction is metallic and solid. I don't find it very fast in the zoom range, perhaps the old Canon super telephoto were more practical in this sense, but not practicing birdlife for me is not problematic. The qualitative difference with third-party optics is evident, I speak in terms of sharpness at TA. Also used for an indoor gymnastics event, it fully satisfied me; albeit paired with the Eos R which is not the fastest for this genre! A transport bag with padding must be purchased separately, since in most backpacks it will hardly fit . . .

Pros: 1 stabilization, 2 sharpness, 3 weight.

Cons: Lack of Arca Swiss in the foot.

Opinion: I bought this lens mainly for hiking and long walks in the mountains, for its low weight compared to the Canon 600mm f4L, and I must say that it does quite well, the stabilization is excellent and allows me to get shots in very slow times, the sharpness is good, but if you want to add more detail I recommend closing at least another 2 stops. The quality seems good, among the things I didn't like the lack of the click of the lens when centering with the foot and lack of arcaswiss in the foot.

Pros: Focal range, price, colors and definition decidedly valid, weight all in all low and good handling

Cons: Autofocus in difficulty in some situations, lack of distance limiter, a certain general latency.

Opinion: Purchased essentially for plane spotting, among the positive aspects I would put first of all the focal range, and then the good optical quality, with the right times you get respectable definitions, with a significant improvement compared to the Sigma 150-600 Contemporary used so far. The mechanical construction seems to me all in all aligned with the cost of the product, it should be noted that although it is not an L series it is still supplied with a lens hood. The weight is also to be counted among the advantages, the lens proves to be manageable and not tiring, at least so far I can't complain in this respect. I must also say that aesthetically I don't mind, the fact that it lengthens with the focal length does not bother me, since the Sigma was already similar in this respect. The only two limits are a certain general latency and a marked difficulty in finding the correct focus in some situations, in this the lack of a limiter regarding the minimum distance certainly does not help. However, I consider it a lens that is fully worth the price paid, the uncertainties it shows from time to time all in all are acceptable also because I have encountered them in quite particular situations, during normal use there are no problems.
