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.)

is the 55-250 STM worth trading up for?  currently i use the 55-250 ll, the original lens that came out years before the STM.

thanks.
