Re: High ISO limitation?

I was a little disappointed using it at high ISO... it doesn't look ¨too¨ sharp as I expected to be an L lens of this price tag,

I must admit that your statement makes me question the whole review. Image quality due to the lens should be consistent across all ISOs - there really is no connection between the quality of the image leaving the rear of the lens and the camera ISO.

Now, the all-in-one lens is a little slow at longer focal lengths, and the slower aperture means you would need higher ISO. This is physical limitation of a lens covering such a wide focal length.

This may be better than average for a zoom covering such a wide range. But there is no way that it is optically as good as the newer L lenses covering narrower ranges. The main thing that makes this an L lens is the robustness and weather proofing, but I bet my cheap 55-250 STM lens is just as good optically over the 55-250mm range. (The STM lens is as good as my 70-200 f2.8L IS where there ranges overlap - except for the faster aperture, robustness, and weather sealing.)

Jeeeezzzzus.... If you have to use high ISO it’s usually because the light is not too great. And if the light is not good the images won’t come out as sharp
