Nikon 24-70mm woes :(

The lens *might* be slightly soft at 70mm f/2.8 but that doesn't seem to bad (i.e. the test images would normally need stopping down to f/8 ish to look good). Shooting at over 10m to infinity at flat targets may be more informative, and double check the focus with liveview. Don't forget 70mm is the long end of the zoom, and if it is anything like the Canon one, it probably is perfect at 28-50mm - does it look OK at that region? D

If you are still worried take it to fixation asap, as otherwise this issue will haunt you for the next 2 years and it is not worth it.

btw. 50mm f/2.8 on crop would be more like 70mm f/5.6 on FF in terms of DOF.
 
For what it's worth, I think they're soft. I pixel peep all my purchases ( a bad habit) but I like to know what I'm buying. My D3 and 24-70 combination is so,so, ridiculously amazingly sharp at 2.8 in unsharpened RAWs that it makes me want to bin all my other lenses! I normally focus test/pixel peep 100% at my photos. With the 24-70 it was so blindly obvious it was a flawless lens that I didn't bother. I will email you full size raws if you like?

I definitely agree for a professional opinion at fixation. I wouldn't be happy with it myself, but many people might be. It will eat you up for all the years of ownership!
 
Having borrowed a friend's 24-70 a few weeks before I know what you mean. I was blown away by how sharp it was. I'm no pixel peeper but I'm convinced this lens isn't putting out the results that it should. I'll take it to Fixation tomorrow and see if they agree.

Was just testing AF. Put the lens on the floor (no tripod atm), focused on subject, used AF, click. Fine. Switched lens to MF, put on Live View, manual focus zoom in, click. Subject is OOF, focus as moved behind it. 1/500. Camera didn't move between shots. Repeated this three times to make sure. Switching the AF switch to M on the body as well seems to cure it.

Serious question for people who have this lens, when you hold it horizontally and shake it, lightly, from side to side, can you hear anything moving?!

Not a thing heard.
 
I'm late to the show, but when I dont have a tripod available for whatever reason and I need to use a fixed camera I blutac it to a table or desk, this is usually "fixed" enough for me.

I'm going to take issue slightly with the way Sam raised this problem. By naming the guy he bought the lens from in the first post, plus linking to the sale thread, he has effectively dragged this guy's name through the mud BEFORE the lens has be proven to be faulty!

As far as I'm concerned Sam should have produced a thread asking how to check if his "new" 24-70 is a good or bad copy, not name names and potentially finger point. If the tests were to prove beyond any reasonable doubt that the lens is fubared then he might have a case for letting the TP community know what the sellers response was, and not before.

Poor form in my opinion :nono:
 
Just heard back from fixation and, whilst noting a few other issues, have reported that all test results are "to standard". I maintain that the results are not as sharp as the copy I previously used but will have to live with it. I have apologised to the seller and removed all references to the sale. There has been no damage done, anyone who has been following the thread will have seen the conclusion, and anyone who hasn't will be none-the-wiser. Thanks to all who have offered advice. Time to sit back and wait for the criticism and "told-you-so's", but I can take it. I apologise to anyone who thinks I have acted out of line.
 
To be honest it sounds like the worst result possible for you. I suppose you'd probably have prefered them to say it was faulty and with a fix it'd be as sharp as you'd expect. Paying around £900 for a lens you're not happy with has to be gutting.

I suppose you could always sell it on and buy another copy of the lens and hope it's a lot sharper.
 
Mixed feelings really I guess. I will see how I get on with it in my next couple of assignments, and if I'm still not happy I'll sell it on. Although probably not on here or I might get some stick :lol:

Shoot a person Sam (not literally, that'd be daft) - see how it goes in real life.

Thanks Guy, have a variety of portrait shoots to get my teeth into, just as soon as these pesky exams are over.

Andy, I was pretty sure you would be right given your experience, but I had to make sure.

A matter of opinion.

Don't be so quick to point the finger next time - unless you're looking in a mirror!
 
Sam has had the good grace to admit he was wrong and has apologised. Let's not turn this into a witch hunt please.

Absolutely no intention of doing that. Merely pointing out that others may have a different opinion as to whether it was 'no harm done'.

Apologies are fine but but don't necessarily make everything right again.

It is a matter of opinion indeed and my opinion is the same as Keiths.... please move along.
