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.

Greetings trossit,

I agree with Wadizzle the 10-22 was best in its class.

Its an Ultra Wide Zoom, not "super'

Your shot... You need to consider what you are asking of the lens in this case. You are going to get a wider FOV, but the lens itself does not have the "reach" to bring a subject at infinity into sharp focus.

Sharper focus might be achieved by shooting at f8 or above, but at 10~22mm the focal length of the lens has limits. You can break your image down into 2 catagories.

Yellow plants in are foreground, green trees mid, and the city scape background. Aperature and your focus point can influence what will be in the sharpest focus (to a degree).

Or

Shoot at 22mm (infinity) and f16 or above for the sharpest overall portrait. (Fore, mid and background). Time of day and amount of avaialble light might also come into play. That high cloud ceiling may limit the amount of availble light, so your ISO choice might also influence the overall clarity and end result.

This lens has limits. Its very popular for vlogging and video due to its silent AF. If you consider what you are asking of the lens, I think you will be happier with the resilts.

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?

ebiggs,

Thanks for the tip on Canon DPP4. I downloaded the software and used it last night and it was fast and effective. My only issue with it I did not find a "Graduated Filter" as seen in RAW Theoropy which I find effective in calming down over-exposed sky's. In DPP4 you mentioned you apply a mask for the sky. Did you mean the function called "Set Adjustment Area?

I took some more pictures yesterday and my expectations for wide angle lenses may have me over-blown. I will try to attach 2 pics what I feel WA lenses are strong at and what they are not strong at. Curious if you agree.

1 - Picture of sailboat just off the shore that is much closer to the photographer...better detail.

2 - Picture taken from a bridge of a far away cityscape - lacks sharpness and detail.

BTW, your photo looks fine. It is a typical representative of a scene like that. If you need more IQ you need to do as suggested above and use multiple shots, preferably form a a mid tele, and stitch them together in Lighroom or some other stitching software of your choice.
