Focus problem with D800?  Rating:  Rating

Anybody have the left sensor focus problem that people have been raging about in the dpreview forum?

I got mine last week and have tested the focus with 2 lenses- seems spot on.

On another note, how is the D800 focus for moving action? I just sold the D3 and am a bit sad to see it go. It was a great camera and focused well fr my kids' sporting events.

I didn't know this problem existed until you mentioned. I'll check my D800 when I have a chance. I tend to always use the center focus point, so even if mine is afflicted I wouldn't notice.

As far as moving action focus is concerned, mine is very good. See my post on page 3 of the "D800 cropping and hand holding" topic HERE.

Great pics Dave, especially the funny car in motion. Very sharp for a hand-hold pan shot.

Are those jpegs out of the camera or processed raw? Nice color saturation- wondering what your settings were.

Regards
Jim

No problem on my D800. AFAIK.

I do worry about the DPR forums as they are full of trolls who seem to make up problems. However the worry is for every 100 trolls there are other genuine people who report real problem but are at risk of being ignored due to past rubbish.

I had a look through the Nikonrumours D400 article comments (the one you linked to in another topic).

Some of the comments defied belief, commentor A would say 'I need xyz' and commentor B would deride this but go on to make comments about commentor A's mental faculties, character and parentage and anything else unpleasant you can think of.

Seems some of these folk have a very little tolerance for any point view but their own and are incapable of understanding that sometimes different folk have different needs, expectations etc.

Yes, they are jpegs straight out of the camera.

I know I should be shooting raw and normally do, but my computer is not up to it. I use Lightroom, but the latest version is required for the D800 NEF converter. I cannot run the latest LR because it's Intel-only and I am still using a PowerPC Mac.

Since the race shots, I've started shooting jpeg+raw. I import the jpegs into LR, examine them, and convert the NEF keepers with Nikon View for further editing in PS. Each conversion takes a minute or two on my Mac Pro Quad-G5-processor with lots of RAM.

One of these days I will get a new computer, but I just bought a D800 which showed the limitations of my lens. So then I had to buy a 24-70/2.8. After the computer I will have to upgrade LR and PS. First things first, second things second, etc. I could buy a lot of Tri-X and Dektol for all that money.
:banghead:

But then you would get yellow fingers and smell of chemicals!!

I think the digital world whilst having limitations is much more friendly (ecologically and person to person) than the old film stuff.

At the risk of getting shot :devil:


You could convert into DNG using the Adobe NEF to DNG convertor and then put through Lightroom. Annoying but might bridge the gap for now?

Tom Hogan musing about reported D800 focus probs. He suggests users need to master system. Seem to remember D2X and D3X had similar problems for some users.

The controls for the AF settings are located differently and people tend to assume that factory defaults work best.  Sometimes but not always in my experience.

I agree user error may be a factor especially for all the prosumers picking up this camera. In my experience (amateur) the D800 is much less forgiving of poor technique and requires faster shutter speeds to get the sharpest pictures. It also seems to highlight imperfections in lenses that didn't show up as much on the D3.

No focus problems either with still photography. With video ONLY and live view it does not always pick up at once and needs to be worked on on poor light.

Have been offline last three weeks location filming in N Wales back now after some very wet weather but finished the project OK.

I have seen no problems and have used the left focus in routine work

If you stick the Focus Box over the subjects shoulder, or off in the wild blue yonder, you might just notice a bit of focus shift from the subject???

ya think???

:salute:

Ray yes but any Nikon DSLR would do this if focus box is moved off the object required. I have just been filming in N Wales and a Red Kite flew past me several times so I got the D800 in action locked on focus and took several un-sharp pix!! Not my normal type of photography so I was not too upset it just made me aware just how good some of these wild life photographers like Andy Rouse are.

I have always been frustrated when ever I try to shoot anything in flight, bird especially??? I know how to shoot race car, fast motorcycles, and the occasional airplane, but put feathers on it, and I'm lost???

And because you are shooting against the light you need to give it +2 EV and it moves fast and sometimes erratically.
Just shows how each different type o photography has its own tips, tricks and learnings.
