Focus Problem
I just did a quick last minute outdoor shoot with a friend of mine. I shot with the D7000, 50mm 1.8D and a SB600 on board for fill. I shot at ISO 250 - 320 most of the time, 1/250th and f1.8 - 2.0 The model was generally at least 15 away from me. I know when I shoot I focus on the models eye each and every time. Sometimes I miss when there motion but that doesn't apply here. I got home and every friggin image is out of focus. So I opened up View NX2 so see what it said about my focus point. The confusing thing is it shows the focus point as being the center of the image on every single image I have. Including things from previous shoots that are fine and focused correctly. What went wrong here? Examples can be found here. These are cropped and slightly retouched only for exposure items http://adldatacomm.net/clients/mm/examples/ Jan 13 13 03:07 pm Link Hmm I'm a Canon user so I doubt I can help a lot. Maybe you've got "two problems" : - the focus point data being badly registered in your raw pictures - your focus problem. That might be stupid to say but now that you've shut down your camera, do you still have a focus problem if you restart it ? Jan 13 13 03:18 pm Link Examples still uploading at 6:20 EST I don't know, that's a good question. I'm going to set up my focusing test system and take a look at what's going on. NX2 shows the focus point in the center for images shot 2 years ago that came out fine. It's so odd because it used to be accurate. Maybe a recent NX2 update broke it? Of course that doesn't explain my out of focus images. Jan 13 13 03:21 pm Link It already happened to me that some focus points were working in a weird way. Usually turning off / back on my camera solved the problem. Maybe moist on the lens because of temperature differences ? It's a bit stupid to say again, but your problem sounds a bit weird (unless it's just a minor camera bug) Jan 13 13 03:30 pm Link You can change whether it spot or multi point focuses. I keep mine on spot, focus on the model's eye, hold the shutter half way, and move the frame where ever I want. Jan 13 13 03:37 pm Link Jackson frontier photos wrote: Exactly. I should have mentioned that. I use single spot focus. That's exactly how I shoot. Focus on the eyes, recompose and shoot. Jan 13 13 03:51 pm Link Is it a focus issue? Or is it a softness issue? Because even at f/1.8, you've got a depth of field of about 2ft on the D7000 focused @ 15ft but the 50mm f/1.8 is pretty soft wide open. I rarely shoot mine wider than f/4 to keep it really sharp. Jan 13 13 03:56 pm Link Aaron Lewis Photography wrote: Well, it happened to me a few times to see my lens cover with moist because of temperature differences, but usually it was VERY noticeable. However I believe that it could sometimes not be easily noticeable, maybe if the air is not too humid. IDK, that's just a random though Jan 13 13 03:56 pm Link some of the d7000s have focus issues. Mine is set to -18 on the AF fine tune as default for all lenses. Nikon will repair but since the AF fine tune took care of it I didn't bother. Sorry.

Jan 13 13 04:08 pm Link I don't see anything wrong with some of those shots. Thought they were pretty good. Jan 13 13 04:25 pm Link Jackson frontier photos wrote: Thanks, I think they're pretty decent over all but the llamas face isn't crisp. Having said that we were actually going for a nice soft look but I intended on doing that in post LOL Jan 13 13 04:32 pm Link I didn't actually notice the link to the example images before. Some of them definitely look like either it's focused on something else or it's backfocused, but others do just look like softness inherent with shooting a 50mm f/1.8D wide open. Jan 13 13 04:35 pm Link If you were set on center spot and focused on the eye and then recomposed, View NX is displaying what it should - the center spot. The camera doesn't know that you recomposed. Jan 13 13 04:36 pm Link Aaron Lewis Photography wrote: I have never had issue with NX view showing the wrong focusing point. If you are focusing at the model's eyes, what I saw from the images you shown, they aren't consistent. Meaning that some of the images were back focused and two or three were in focused (but the ones in focus also is more focus in the center). Jan 13 13 04:37 pm Link Yeah, I'm a little pissed. I had this opportunity to shoot with a professional model. My friend called me up wanting to take advantage of a foggy rainy day for the look. Only to have it all fall apart. I guess I'll use what I can and write it off to experience. I also submitted a repair request to Nikon just to make sure everything is in order. ChanStudio - OtherSide wrote: Yeah odd. This lens is usually spot on. I'm really disappointed. There's no reason for the noise or that much softness. Jan 13 13 04:40 pm Link Aaron Lewis Photography wrote: I would recommend try to ping point exact what the issue is before you send it to Nikon for repair. Otherwise the issue won't be fixed correctly. Jan 13 13 05:02 pm Link Image 3991 has camera shake. The light reflection from the eyes shows it. The rest are mostly out of focus. The camera/lens combnination could be struggling with limited light. Did you check if the AF switch is on normal or "C"? The D7000 has only AF and M whereas the high end DSLRs have the AFC option. Check by pressing the center button of the AF-M switch and rotating the rear control dial. . Jan 13 13 06:22 pm Link Raoul Isidro Images wrote: Camera shake at 1/250th shutter? That would be pretty severe shake, no? There was a Gary Fong light dome on the camera mounted SB600 Jan 13 13 06:29 pm Link Aaron Lewis Photography wrote: That's not going to do much outdoors with nothing to bounce off. You'd have been better just pointing the bare flash right at her for fill and not lost all that light going off in directions where it was doing nothing useful.

Just trying to soften it up Jan 13 13 06:39 pm Link Raoul Isidro Images wrote: I saw that as well...if that was the first photo. Jan 13 13 06:46 pm Link PhotographybyT wrote: Yes, that was the first photo. Jan 13 13 09:41 pm Link Plus 3991 is focused on the log at the bottom. Maybe when you recomposed or the focus needs some fine attunement. Also if they are saying motion blur, which I'm not 100% it is, but it could be as the neck has some light from the neck on the other side, then are you sure your shutter is firing at 1/250th of a second? Jan 13 13 09:52 pm Link Jesse Mullins wrote: Well, That's a) what it's set to and b) it syncs with the strobes fine in the studio at 1/250 so I would guess that if it were off, I have a curtain in the images. Jan 13 13 10:04 pm Link Aaron Lewis Photography wrote: Even if it was set to that and syncs with strobes fine that doesn't mean it's not shooting slower and dragging the shutter open longer then the 1/250 but then your meter would be pretty far off from the shots you were getting. Jan 13 13 11:05 pm Link Not sure about nikons but canon has one shot and AI Servo for AF systems. Could it be that you are on the Servo equivalent? There fore half pressing the shutter wouldn't actually focus lock and it could refocus when you recomposed? Only other thing i could think of is perhaps you focus locked, then took a step closer or further whilst holding the shutter button half way down?

Even If I were closer than I think and I was shooting at 10 ft I still have almost a foot of focus area. Gavin Poh wrote: The continuous server is pretty obvious. It's actually quite annoying to use in most cases so that's not it But,as mentioned above, maybe I was just inaccurate with the judgment. I moved like you said and didn't realize what I was doing.
