This lens was tested by photozone.de and recommended, they said it was almost as sharp as the L 2.8-4.0 28-70.
I think it's crap, soft at 4.5 and 5.6, barely acceptable at f8, if this were an old manual lens I'd throw it away. Contrast is not good and colours lack vibrancy, nothing about it looks good to me.
Are modern Canon AF zooms really this bad? If the L lens is only slightly sharper then I really do despair. I need to produce 20x30 prints and virtually all my manual lenses are capable of at least acceptable quality at that size, but I shudder to think what a 20x30 from this Canon POS would look like
No PP at all, just resize.
#1 f5.6
#2 f4.5
#3 f4.5
#4 f4.5
#5 f6.3 this one really p*sses me off, 2,5m distance, stopped down and still soft!
#6 f8 acceptable, but all lenses should be acceptable at f8
#7 f4.5
#8 f4.5 This makes me wanna punch some Canon executives, centre sharpness of this level is totally unacceptable for all but the blindest shooters
#9 f8
#10 f4.5

I think sharpening will work on the f8 shots, but on the others, the detail just isn't there.
This really bothers me, I need an AF lens of good quality, I did a lot of reading and research before I picked this one, to quote photozone.de's test report:
Quote: |
In the lab the lens was pretty capable to live up to its reputation. At 28mm the quality is already pretty good at wide-open aperture and its increasing a little bit to excellent levels at medium apertures. At 40mm and 70mm the lens is even a little better. It may be surprising but according to the local Imatests the lens is only beaten by the EF 28-70mm f/2.8 USM L and even here it´s quite close. |
Well, my experience is markedly different, so what's the case?
- Photozone got it wrong
- I have a bad copy
- Photozone are using low standards so 'pretty good at wide-open' in their world translates to 'soft mushy crap' in the MF lenses world
If Photozone are using low standards (as a consequence of all modern zooms being at a lower level of quality) then I'm really worried, I need a good AF lens without paying a small fortune. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

there is a way to calibrate the autofocus by lens, check if the 450d can do it or use liveview to make your tests _________________ T* |

I tried sharpening a couple of the crops with 150% strength in NIK Sharpener, first is at f4.5, second at f6.3.
Helps but still crap.
I have to ask, is this a bad copy or are Canon EF zooms just bloody awful?

Cheers, I will take it out tomorrow, stick it on a tripod and use liveview.
Fingers crossed I can get better results. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

Crap. Just ignore my post. You bought the faster EF 28-70 3.5-4.5 II. Guess I need to read more carefully. _________________

I checked Flickr, it seems some copies of this lens are half decent. There are a few nice pics here:

But yeah I think it's tripod and live view test bench time, you might have yourself a lemon copy.
Which autofocus mode are you in? My EF 50/1.8 was driving me INSANE until I switched modes. I don't remember the terminology, the default is for the camera to guess which AF point(s) should be used for focus but you can force one single AF point. I switched it to the center point and instantly got better shots. Obviously sometimes you don't want the focus to be right in the center but it's easy to recompose after the camera achieves focus. _________________ I welcome C&C, editing my pics and reposting them on the forum is fine.

Cheers for the tips guys.
I tried to try the lens again today on a tripod, but it won't focus at all now, seems it's jammed as turning the focus ring in M mode doesn't budge anything, it's stuck at 0.6m.
Seems the lens is broken, I asked seller about return for refund.
I tested the camera with a Helios 44-2 I know is sharp, just to be sure.
The light was crap but the camera produces decent results, I doubt my NEX is much better in this light. No PP, f8:
And after fixing contrast and sharpening:

May be you got a bad copy. I have one and used it on the 5D. I was not disappointed, and certainly the photos look way sharper than yours on the FF? |

Yes, perhaps a bad copy. I recommend the nifty-fifty, EF 50/1.8II. Fast autofocus (on my EOS In) and sharp as hell.
If you look around, you can get if for <100 bucks, too. |

Another body or two costs less than one quality zoom.
Purchase a couple of used 5D classics, for example, then wear three cameras with three fast primes, say 35 & 135mm on 5Ds, 50mm on 450D -- you get backup cameras, you get prime lens quality & distinctions into photos... _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮
