Canon EF-S 10-22mm, 3.5 - 4.5

Hi Room,

I just recenly bought a used by pristine Canon EF-S 10-22mm, 3.5 - 4.5 Super-wide -angle zoom lens off Ebay.  Not being experienced with the typical behavoris of super zoom lenses, are they supposed to be tack sharp like a 50mm prime or tele-zoom lens would be?  When taking a picture of citiscape with my focus on the buildings on the far background they dont come out very sharp.  I will include a sample photo.  Should they be as sharp as other types of lenses?  I will include a sample.

"My only issue with it I did not find a "Graduated Filter"  ..."

DPP4 is not Photshop or even Lightroom.

"I took some more pictures yesterday and my expectations for wide angle lenses ..."

The reason you use a WA or UWA lens is 'angle-of-view'. That's it. Nothing more or less, AOV.

"... I am using an older body 30D with 8.2 mp sensor...."

The over ridding fact is the 30D is a 20+ year old design, never mind the 8MP sensor. You would expect any newer tech to be "sharper" and altogether a better rig. Your lens is also an older design, 15 years old. It has significant chromatic aberration that a newer camera would correct. It can also be corrected in post but it you don't it can make your shots look less sharp. Diffraction will hinder the image at the smaller apertures, too.

Whether you would be better served or see more enhanced pictures with a newer 90D and the newer, better, EF-S 10-18mm f/4.5-5.6 IS STM Lens, would be a decision you will have to make.

You do know that the photographer himself/herself, you yourself, is the biggest critic. You shots look fine. Again what is the final goal, use of these pictures?
