Leonard Shepherd

More than 30 have "complained" at dpreview - and about 35 have posted images. However in every image the AF target used is one Nikon say can cause mis focus. While there may be the odd genuine...

For wildlife photography the entry cost can be much lower than big lenses, plus more working distance with macro, plus probably much faster fps than a D800. The "need" will not be as great as 12...

The internet "word" is 30,000 units a month. Whether the internet word is right is another topic - at about 3 times D700 numbers it could be. -- Leonard Shepherd 99% of photo equipment is good...

If they do so far at dpreview almost 40 claiming a fault have posted images ignoring Nikon's guidance on using AF sensibly, and nobody seem to have posted a link using reasonable...

The AF point is over the fence panels which do not show good contrast. The 99% likely issue is the AF has failed to focus good on a poor AF...

My question are other people finding the same sort of adjustments needed in using long lens? The +15 seems excessive for the tc 1.4, the -5 on the tc 1.7 seems ok. The 5AA batteries are...

In a way there was less need for discussion because manufacturers published resolution and colour characteristic charts for film. You knew more or less what to expect. Resolution targets while...

The 50mm focus ring should be smooth turning, though slightly noisy, part reflecting the price difference. As the lens is new if it is not smooth turning exchange it or get your money...

The reason for asking is your AF target looks like one which Nikon say can cause mis focus :( Maybe if you get a third copy and test it sensibly you will find you have a good copy...

Having just taken the trouble to go through it the "evidence" seems to be 1/ a dubious report from a repairer who does not seem to be an authorised Nikon repairer 2/ images from Horshack,...

Has there been an AF issue with the D800? The reason for asking is 1/ after more than a month on sale Nikon has no service advisory 2/ although there are lots of threads at places like dpreview...

As some-one who shoots with both cameras, plus D3s, the D7000 AF is slightly more likely to hunt with some subjects and slightly less efficient at focus tracking than the D300s. This is logical as...

We have only your version of what was said. Maybe the technician said the camera does not focus "properly" if you ignore the camera guidance on how to get good focus. The pictures you posted...

Why on earth you cannot work out why your test subject is useless for focus calibration is beyond me. If you cannot work out why from Nikon's guidance in the D800 instructions or on the web -...

Garbage conclusion? Of the 31 or so who have posted images or links at dpreview *NONE* seem to have tested reliably following Nikon's guidance on getting good results using AF printed in the D800...

Is it all over the net? It is not mentioned on any pro user Nikon forums I visit. I think I am showing respect. All I am asking is that *ANY* who say they have a problem between them at least...

You are talking strangely - diffraction applies at f1.2 in the "Nikon sense" - f1.2 being the fastest lens Nikon seem to have made. AF reads wide open - which depending on the AF lens maximum...

It is fairly straightforward. If you do not mind a fair bit of post processing as DR improves at lower ISO's there is less need to use grads. If you prefer to get things good at the shooting...

THERE IS ABSOLUTELY NO EVIDENCE OF A WIDESPREAD FAULT :) The reason for saying this is this is a photographic forum where it takes only seconds to post an image showing a fault - if there is one...

Less coffee and learning long lens technique should help http://www.moosepeterson.com/techtips/longlens.html Wide open it scores over 90 in the corners at 300mm at 10 lpm and 60 at 30 lpm in...
