Yes
i have the 105 and its not V sharp .. i mean its sharp enough but the IS is noisy it sounds like a train and the quality isnt what i was expecting .. in fact im quite dissapointed :(

Is it just me?

Should i exhancge it for the 24-70?
 
In all honesty, going by your recent threads it probably is 'just you'. By most accounts the 24-105 shines better on a full frame sensor and the 17-55 IS is considered 'the' general purpose lens for a crop sensor, but I' sure you've read that for yourself.
 
no really its not me.

Someone else has borrowed it .. someone who owns several L lenses and they were dissapointed.

And im not deaf i know how loud the thing is
 
If you know the answers, don't ask the questions.

Take/send it back then.
 
Whilst not the best performing lens of the "L" range, it is generally considered to be a real work horse. I have hired one on a number of occasions and used it on various crop sensor cameras. If you feel that the one you have is not performing take it back.

I will reiterate however that, for a crop sensor Canon, the 17-55 is probably the best all round lens available. If you don't need the narrow end, try a 24-70 f2.8. No IS but sharp as a tack.

IS has proved unimportant as i turn it off on a tripod anyway

Just really peeved with £900 being as soft and not as sharp as it should be

Perhaps the 24-70 is best but i hear its very heavy

I also dont use wide end so 17mm is no use to me :)
 
Hi Daniel, I have exactly the same set up as you i.e. 7D and the 24-105L and all I can say is that I find the lens to be very quiet in operation (sometimes wonder if the IS is actually working) and extremely sharp even when pixel peeping.

Therefore if others have confirmed issues with the lens and therefore it is not your photography then I would take the lens back, as I really can't fault this combination.
 
Any chance you could post some pics to show how soft?

Thanks Paul :) what sort of shots do you take with it?
 
This is my first post here and I would just say that I shoot the 24-105 on a 5DmkII as well as 7D and have never been able to fault it (originally got it with my original 5D quite a few years ago). The only poor (ish) results are at about 70mm where this lens has always been known to be slightly down on resolution compared to other lengths. The IS is almost silent as is the AF so I would guess that unfortunately you have a bad copy and would get it sent back.
 
I know lots of people that use that lens, and although its not a massively fast lens, generally it's accepted as quite sharp?

Initially you said you were going to be shooting solely in a studio if I remember correctly, based on your last "what lens shall I buy type thread", and at between f8-f11 you shouldnt see much/any difference in quality between this lens and the 24-70 2.8.

So, my question is, when/where/how did you test this lens? If you're shooting it wide open at f4, with slow shutter speeds, even with IS on, you won't beat the 24-70 for sharpness.
 
Dan, if you're shooting in a studio, why have you got the IS turned on ? If you're handheld the flash will "stabalise" the image, and if you are using a tripod it should be off anyway.

The IS on mine is almost silent too - on my 70-200 f4 the IS makes a fair noise, so maybe yours is slightly faulty, and given your worry about it being soft it does seem like it needs to be looked at..
 
ive been trying to shoot wide open on occiaisons as a walk around lens in several different environments and i was not happy

i took it to a freind who is a tog and he said it was a poor lens also

i figured the 24-70 would be a better option as the IS is kind of null and void anyway i dont use it .. and the 2.8 might be nice for some bokeh .. wouldnt change out of the norm but while im swapping a faulty lens seemed sensible ..
 
Danny, my niece uses that lens on her 5DII and isn't impressed, so you're not the only one.

How about shooting off a few trial shots wih something else like 24-70mm in a shop and analysing them before making your mind up?

its always off mate - tried using it on to see if its broken but its proper noisy .. when im in a quiet environment it sounds like a plane taking off
 
If you are not happy with it you will always have a doubt at the back of your mind when you are using it, regardless of how good or bad your copy is.

Most lenses won't perform best at full bore. In fact I don't know of any that don't improve, even slightly, when stopped down.

The 17-40 has some quite bad CA in the corners at 17mm, but it doesn't stop me using and loving it often. By 20 or so mm the CA has gone - and besides, who looks in the corners anway? Point being if you look hard enough any glass will have optical flaws somewhere. A lens with a range that the 24-105 has just isn't going to have prime sharpness across the board - something's gotta give.

Actually that's a common fallacy - f/4 at 105mm will give you more than enough scope for an out of focus background, and due to the extra magnification you'll probably find it actually looks as good as if not better than 2.8 at 70mm.

At the end of the day, if the lens is knackered, get it fixed or replaced.

ok so before i go pick the ******* up or start another thread

24-105 .. over the 24-70 as its newer, cheaper and has IS .. agree?

i will shoot at approx F8 for studio anyway so 2.8 is pointless for me

As trencheel said, if you suspect it has a problem take it back and ask for a replacement/refund.

the F4 is more than enough for inside work!

I posted on your other thread (above quotes), giving you advice based on the fact that you had insisted the lens was to be used inside, with strobes. For studio portraits or whatever. If this was the case, then either lens would be near identical at f8-f11

Now you're testing it wide open outside in possibly poor light with IS turned on and complaining that's it not as sharp as you'd like, which is nothing like a studio scenario. Is the lens faulty? Maybe? Get it checked?

Either way, why buy a lens specifically for studio work and complain when it's crap at things you never intend to shoot with it?

Even if the lens wasn't faulty...I suspect this thread would still be here. I'm not slating you mate, just doesn't sound like you know what you want, or what you want to shoot.

Get the lens in to be checked, everyone else I know that has one says it's sharp and the IS should be relatively quiet. In the mean time, spend some time thinking about what you want to shoot, and have realistic expectations about what to buy based on that. For example; If you wanna concentrate on shooting beauty in a studio I'd recommend a 100mm or 135mm prime, but whats the point if when you get it you're gonna take it to a rugby match and complain that the focus isn't fast enough...:bang:

And how much are you in love with your 7D? Hope you're settled with that decision :thumbs:
 
look the lens is for indoors under strobes BUT its my only lens so if i want a photo of my cat taking a dump i have to use the 105 .. and the crap stinks! its soft whereever and not sharp .. doesnt matter if its f11 or f4 .. its dodgy

the 7D is gods gift to me .. its fantastic

Then it's probably faulty, so get it fixed rather than chosing a different lens AGAIN

In good light, properly exposed, that lens shouldnt be soft, it's faulty, it doesn't mean you now need a 24-70 2.8.....
 
i never said i NEED 24-70 ffs i said is it worth that instead seeing as though its being changed? blimey
 
Post a shot from it with the exif?

What kind of response is that?

Your lens is faulty, which will suit your needs, you decided to buy it, but because it's faulty you're considering a whole different lens.

Just get it repaired, every consideration you had for getting this very lens in the first place still stands!

Unless of course you've changed your mind from having a dedicated lens for studio work, to a lens that can capture a cat taking a crap in natural light?

In which case, you need more than a rethink about your lens choice!
 
Are you sure it is focusing properly? My 24-105 front focused and was soft until it went back to be calibrated (it was second hand but under warranty). Now it's bloomin sharp. Have a look at this thread http://www.talkphotography.co.uk/forums/showthread.php?t=258138 and do the cereal box and ruler test shown in there. If you focus on the cereal packet, you will see where the main focus point is by looking at the ruler.
 
Have you tried the AF micro adjustment feature on the 7D?

It wont cure the IS issue of course. Sometimes my 100mm L IS macro makes a loud noise, sometimes not.

there has got to be about 4 series worth of a sitcom in these threads. lovin' it :lol::lol:
 
Dan,
As others have said, get the lens checked out if you are not sure, take it back to where you brought it and compare the noise of the IS and if possible take a few comparison shots in the shop, you should soon be able to tell if its faulty. As Martyn said, if you have a doubt about a lens it will eat away at you all the time.

Also lenses are never the sharpest wide open, they always need to be stopped down a little to get the best out of them, no matter what lens it is just the nature of the beast.

Good luck getting it sorted, and don't let a bad copy put you off, you can get this with every thing in life ( as I am sure you know.)

Hope this helps a little and I look foward to seeing some results of your new kit soon.
 
The IS on my 24-105 is not noisy, you can hear the faint whirrring when in a quiet room but that's it. You need to get that lens looked at, if you think the IS is noisy then other lenses (17-55, 70-300, etc) all exhibit the same faint whirr, you'll be better off with a non-IS lens.

My 24-105 is sharp wide open and bloody sharp just stopped down slightly at f4.5. Its an amazing lens no doubt and I'll never let it go. You must have either a duff lens or you need it calibrated to your 7d.
 
an example although its made me look a cock as it doesnt look to bad however IS is still whiring like a train ..

Get it checked out. IS is usually fairly quiet, though not silent. Did you use IS on this shot?
