iv just got my hands on a second hand nikon 14 24 i paid £1000 for it
as he said it was three month old when i was i reading reviews on this lens saying how sharp it was but i don't think this one is i seem to be applying a lot of sharping to my images
i took this at f16 in back garden i did this on my new nikon d800 and nikon 24 70 is sharp and my sigma 150 is sharp is it or the lens its not a nice image i had no time to go out really thanks

I've just had a look at the original size images and the second shot deffo look the better of the two, excellent sharpness, but I think much of what is wrong with the first image is down to strong light really messing the IQ up. There's definite flare going on, as the sky is overexposed and leaking over the fence top. The colour fringing and CAs obviously need to be compared against another 14-24mm to see if it's just down to the light and exposure levels, or whether the lens is at fault. F/16 is obviously going to push a lens to its limit - what it like at f/8 and f/11?

BTW, you need to re-link the images from Flickr as a smaller image size, as it's taking ages to load and then resize via the forum software. There's no need for a 7000+ pixel image.
 
A quick look on google reveals that more than a few people seem to be having issues with the 14-24 on the D800. So I assume your lens is fine.
 
Please put better sized images on the forum....your pictures are huuuuuuuge. :gag:

second image looks like a fair bit of motion blur or a double image around the horizon and fence. OP, did you shoot with remote control and mirror? If not that would would clearly explain it at those speeds...
 
Tripod mirror and remote the second Image was a double. Exposure then blended in for the sky as I can't us filters with this lens
 
Look at the red rug on your first one, I'd say the rug and grass round it are pretty sharp even on the full size version.

Missplaced focus point maybe ?
 
First... f16 is never going to net you maximum quality with that lens, and secondly, the second image has some weird double image thing going on. This a HDR or compsite?

Post up a unedited full res image, let's see what's what.
 
To be honiest I don't see much wrong with the first image besides maybe the trees at the back which could be either the lighting condictions or as has been mentioned the lens focused very closely.

F16 is never going to be razor sharp and the 14-24mm is pushed at the boarders on the D800 the same as all wide lenses.
 
If I wasn't sure about the 14-24 before this, it's helped turn me off at least!

Even if f/16, unless it is because of the slow speeds, I wouldn't fancy the results there at all.
 
Il go on the beach 2 night il takes some images but il after blend them for the sky and il post later out of camra and then sharpend if the missis let me lol

When you start blending images you start introducing another factor for error. A single shot is best for determing if anything is wrong with the lens.

It's an utterly superb lens mate... this one is just not being represented very well. The landscape shot is also cropped from full frame and has been composited with another image.

I'm not at the main computer at the mo, but I'll link to an online image....

I've taken shots easily as sharp, if not sharper than this with the 14-24. It's amazing.

I wish I could take credit for it... but it's an image from the Nikon website :)

Well.. first one you've held a filter over the lens, so any softness may be a result of that. The rest look really poor to me, and not at all like the results I get.

You are focused fairly close to the foreground though. Why you messing with AF tune? Just focus manually with live view zoomed in in order to test it. You can mess with AF tune once you have established the lens is OK or not.

I have to say though... that looks quite poor.

yep, that's worse than Canon 17-40mm :D :lol:

I do however suspect there may be significant user contribution here. Any glass held in front of the lens will kill sharpness faster than AK-47 (also the first pic looks awful for that reason). Secondly, the exposure times of around 0.5s do not give any little confidence. Shoot around 1/320s or faster and that eliminates shake and tripod or shutter slap problems.
Finally, i can see quite a bit of frontfocus. If you want everything from the closest pebble 5cm away down to horizon in focus you probably need f/18 there. On D800 resolution the whole exercise is getting pointless.
Oh and sort out all that CA.

Well.. yes... but you're not exactly doing everything you can to establish whether it's faulty or not.

If you want to settle this once and for all:

1. Do not use any filters

2. Do not use auto focus (and certainly don't be messing with AF tune at this stage)

3. Shoot RAW

4. Apply no sharpening post process

5. focus manually using a magnified live view.

6. use a tripod and remote release

7. avoid going over f8 for this test until we've established everything is OK.


Post up the results. Nothing special... anything... will do.

Yup, simply no point using filters to test a lens
 
Thanks for helping il do it when I get in from work sorry if I'm a past
 
Now these are focused properly, no filters, no messing with AF tune I'd say they're pretty much what I'd expect. Remember, these aren't sharpened, or had CA removed yet. I don't think there's anything wrong with that lens.

except the manually focused shots. Once again they need to be at 2-3m, not 0.2-0.3m! At least AF got that right.
 
Thank you pookey head for your and all I can sleep now lol what do you mean they need to be at 2-3m, not 0.2-0.3m! At least AF got that right. Sorry if I sound thick lol
