These pictures might give the wrong impression, since you've posted the large version where the resizing compensates for the lack of sharpness for a bit. I've taken a look at the first one in the original size, and saw (next to a strange dark line on the transition to the sky, and other chromatic abberations) that it doesn't like very sharp to me. If that is to be expected from this lens is something I'll leave to other Canon shooters to decide. You may have been spoiled by your other lenses, which (if I'm not mistaken) mainly exists of L class primes. These are bound to be sharper than zooms, let alone non-L zooms.

One point though: where was your focus point? Somehow I think that might be in the front parts, since the stones in the bottom seem to be sharper than more upwards. If you want it all to be as sharp as possible, you'd better take the hyperfocal distance into consideration.

Getting spoiled with the L glass Gus?
Im happy with mine.I feel its sharper than the 17-40 I had.

That's why I love my Sigma 10-20 ...

Is it possible to find comparable shots

of both Sigma 10-20 and Canon 10-22? That 10-22 was (and still is) on my list of things to get, but now I'm intrigued by what you've said about Sigma..

Thanks!

Gus, send me the lens, I will try it out for you. Got nothing better to do right now. And I have noticed that you don't seem to be using it lately.

That Sigma gets very good reviews. It was out of stock for awhile. I wanted to buy it. I think B&H just told me that it is back in stock. I can't afford it now.

So, Gus, I would love to "test" your Canon.

Got this from mine last evening. Sharpened with separate lighten and darken layers ala my sharpening tutorials. I don't really know why it is, but this kind of sharpeing seems very important with this lens. It likes those bold dark halos a lot, but if you make the light ones as opaque, it looks horrible.

Here is the image before sharpening (and other PP):

Can you please

... post a few images from your Sigma, hopefully both before and afer PP?
Thanks!

From all the info i have found on the net..the sigma is worse. I think its my problem with settings.

Still pretty blurry around areas like the blokes legs rutt. I dont know what it is but im going to give it a real work out this week-end at all settings to see what i can find.

Maybe so...the 135 f/2 lives on my camera. I have grown quite used to what it produces.

It's a motion blur, 'Gus. In fact, in the first version I enhanced that on purpose at the suggestion of Yuri. Look at the nonmoving parts of the image.

gus

Doh ! Its to the sides like that were i see it start to distort so im quick to blame it. I will see what this week-end brings. I will give you front seat to judge it mate.

And let me sharpen a few from raw before you make any final judgements.

ok..ebay can wait a week

I have been advised that f/5.6 is its best apature...can anyone comfirm what they recon it its from their experience ?

John Mueller

Here Gus a few test shots.

No sharpening applied.Some level and curve adjusments.

Andy

gus,

there is some variations in this lens from copy to copy, but in general, with the two that i've owned, i think that it's a darn neat lens to have, and i think you'd miss not having it. try shooting at 11, 12 or 13 mm, vs. fully wide at 10. make sure your shutter speeds are fast (1/250th and higher, to eliminate 100% the possiblity of camera shake)... check your focus point - you said f/5.6 i dig f/8 on this lens - and f/11 if on a tripod, for a landscape with max dof.

i got some really sharp shots with this lens, gus...

You could also try DxO

They look fine john...what f/stop did you use & was it wide open or 11...12mm as andy suggested ?

Will def take a butchers at the demo & see how it goes...bit steep though dont you recon ?

'Tis folly to post an 800 pixel version of the whole shot and call a lens "not sharp"... Almost every shot posted here looks sharp as a tack, corner to corner.

PLEASE post a 100% crop EVERY time you want to demonstrate lens sharpness or lack therof. Posting a whole photo is only useful in demonstrating vignetting or lack therof, etc. etc.

I will do what i feel like.

& thats enough outta you !

I was lining you up to buy it.

At least Gus left the original image up on his site to view. Just replace the -L with -O in the linked image, and you can see it in full glory. Seeing that first image that way proofed that there is something wrong with the sharpness of that image. To me it looks like its beyond something that in post sharpening would really salvage, but other than Rutt I'm not known for any expertise in that area.

Thanks mate. I dont know what it is.If anyone calls those shots sharp then they need glasses. Is it something in my processing maybe ?

I am going to let rutt loose on it with some stuff i will take this week-end with a variety of f/stops etc.

It's funny, I was actually thinking....since ginger said to send her the lens to test out. Logistically it would have been easier for Andy to ship the lens that I bought from him to ginger and you ship ur lens to me.

gus

Mate i dont ever want to see any lens back that has had a trip with 0zzie Post.
