D5100 "soft" focus real issue or propaganda

Nikon have studied the focus points and said these results 'are not what they would expect'
The focus point on the 1st picture is on the Ferret's collar - but the model dog's nose is the most focused point.
On the scooter shot it is the orange lamp that should be focused - but the trays in the background are sharpest.
Fully auto mode, for 'point & shoot' is a gamble as to what result you're going to get - better off using my old back-up Kodak P850.
Regarding the last post over this being my 2nd D5100, it should be noted the reason it got swapped was the staff in the shop that supplied it also had similar problems when testing the 1st camera - which only goes to reinforce the point that ther is a design fault with the D5100.
Should I also mention I have a D300S.

Both taken with Nikkor 18-200, the Ferret at 42mm, 1/500s & the bike at 32mm, 1/250s , both at f5.6
It has to be said I bought the camera because of its specification - what an array of options at your disposal - i just get the feeling that Nikon have tried too hard and output from their assembly plants vary somewhat. It is obvious that there are those who love the D5100 and those that wish they hadn't spent their money on one. I mistakenly thought I would have the best of both worlds - the spec promises ease of point & shoot for 'snapshots' and the tools to be more creative when I had the luxury of time to create shots with the 'wow-factor' - only I don't trust the camera to deliver what it promised.
Maybe I'm being unfair in comparing the D5100 to my old (film) Pentax SLR but youd have thought the D5100 is aimed more at the newcomer to the DSLR scene and would be a little more forgiving in its delivery - It seems every shot is ahard work or a gamble on the outcome.
It has to be said there are some stunning shots in the Forum's D5100 best shots gallery so the camera cannot be all bad.

I shot with the D5100 for about a year, no focus issues. This is also the first I've heard of an issue since it hit the market. Mass production of anything will lead to some defects, I suspect the percentage is incredibly small.

Agreed. If you can't get good shots with that DSLR, well ... I mean, its not hard, really. The lower end line has many hand-holding features (not saying its a bad thing) Wonder if it happens in auto mode as well?

Oh well that’s put me in my place. I suppose I should also go tell the staff at the shop where the 1[SUP]st[/SUP] D5100 was bought that they too are idiots because bad shots are obviously down to the person pressing the shutter release.
The shop staff had problems; hence its replacement.
Read the earlier posting – Yes, full auto mode also produced poor results.
Unlike some, I am only to willing to listen to advice from an ‘expert’ – so with the focus points as described below the two photographs posted earlier, would ‘eurotrash’ care to enlighten us what mistakes a mere junior member could have made in operating such a simple device?

We only have your word as to where the focus points were. It is easy to have the focus mode off of where you think it is and We all have had that happen. I have managed and owned a number of camera stores and everyone who works in them is not always a expert on all cameras. All we are saying is that a great number of us have or have had D5100 and none of us have seen that problem in any of our cameras. If you have had two such cameras with the exact same problem then there may be a problem with how you have your camera set or what you are doing. You don't list where you are but I would suggest that you find someone in your area that either has a D5100 and know how to shoot it and ask them to shoot your camera and see if it has a problem. Or either take your camera back and exchange it for something else. But the D5100 does not have a widespread problem as you are suggesting.

I tried to apologize before going into it. I'm a mere mortal. I don't have a hammer sent from the god of thunder that enables me to take superior photos. I don't even thing I take what can be considered to be a 'superior' photo...I put my pants on one leg at a time in the morning, and more often than that, fall down trying to do so. Nothing about my online nikonites status makes me any better than you for any reason. All I'm saying is that in AUTO mode with an autofocus lens, set to single point AF-S, it should make a great picture. If it doesn't, then there's a problem. There are just a lot of variables with cameras these days and it's hard to diagnose.

That said, I suspect that the camera is having back focus issues. If the statue of the dog in the first picture is in focus, then the camera obviously is in the wrong. (Assuming that the focal point was in fact on the ferret)
Now, if you were in AF-S with the middle focus point selected, and it did this with an AFS lens, well then, I'd DEFINITELY suspect the camera is in the wrong.

So here's how we trouble shoot this. Take five batteries, any size, line them up in a row. Setup your tripod at a 45 degree angle from the batteries, set camera to AF-S mode, select the center point on the camera, line up that point with the middle battery, and shoot a picture of them at the lowest allowable aperture. The only battery that should be in perfect focus will be that middle battery. All others in that line should have some blur to them.

Also, try this same thing with multiple lenses to rule out that the 55-200 has the issue and not the camera body. This back focusing issue was aparentlly a huge thing with the D7000, but I've not heard any such issue with the 5100.

If it's a problem across multiple lenses with the camera, then it's the camera and not the body. IF it only happens with the 55-200, then the problem is with the lens. Also before doing this, do a factory reset of the camera body just to rule that out as well.

​This is just what I would do. If Nikon said that its weird, then it must be weird. I think it is judging by the info provided so far. I would try to get them, or if you can, get a replacement from the dealer you purchased it from.

For aditional info regarding focus points & you may also be able to see reasonable settings (Ferret 42mm 1/500s @f5.6 & Bike 32mm 1/250s @f5.6)
Yep, done 3 lenses - 18-105 Nikon, 18-270 Tamron & the 18-200 Nikon off my son's D90 (which by the way takes terrific shots with ease). Oh yes, his verdict of my D5100 having had a couple of goes at using it, is not too complementary and not to be repeated here.
I'll certainly try the 'battery' test.
At the moment I have no faith in the D5100+me combination to undertake the wildlife photographs I really bought this small, all-singing-all-dancing camera for.

I suggest turning *off* VR, personally. Now that I understand how VR actually works, I very rarely use it.

Also, it is entirely possible your local shop simply got a batch of renegade D5100's. I mean, a lot of unusual things can happen on the road twixt here and there, if you know what I mean. So even though the '5100, generally speaking, does not have reputation for focus issues, your local supply could very well be the exception. It certainly wouldn't surprise me if it was something like that. S--t doth happen...

Acquire tape measure.

Stretch out several feet of said tape measure on the floor.

Very carefully focus on, say for instance, the 6' mark of aforementioned and laid out tape measure, preferably at an angle approaching 45 degrees. One could also place a small object at a known distance to focus on instead.

Take photo of said tape measure with focus on 6' mark or on small object acquired for said testing.

Check photo at 100% magnification and see if the 6' marker, and/or small object, is in focus.

Thanks HF.. will try this out..
This would be independent of the lens used right?

I am having this exact issue! I have been trying to figure out for weeks why my pictures just aren't tack sharp like they were on my d60. But, how do I change the sharpness setting on the camera? I do not see anything for that in the settings menu. Are you talking about doing it post processing? Thanks!

Need some additional info.

Are you shooting in RAW or JPEG? If in JPEG are you using Fine or one of the lesser settings.

If you are shooting in JPEG have you adjusted your sharpness setting under the "Set Picture Control" menu?

Also Welcome to the forum

If you fill out your profile we can better answer any questions that you might have.

Go to the Shooting Menu (camera icon), then into Set Picture Control, select "Standard" (or whatever setting you use) and from there click right once using the four-way button, and then adjust the "Sharpening" setting to +6 or +7.

Thank you! I was shooting in RAW. When I shot in JPEG, I did shoot in fine. I think I will switch back to that for a while. I can just do so much more in RAW with editing, but I am shooting a small wedding tomorrow and want the assurance my pictures will be sharp. I don't know that I can spend the time sharpening each image afterwards, and to be honest, I have never had much luck with that anyway. I might have to revert back to shooting in program mode vs. manual, and JPEG vs. RAW until I can get the other 'sharpness' issues I am having figured out...

If you need to sharpen a lot of photos fast, this is good tool for the job: IRFanview. When I don't need the all out, balls-to-the-wall power of Photoshop, I turn to IRFanview. It's light and fast and the sharpening is surprisingly effective and simple to use. You just click on "Sharpen" from the Edit menu, or use "Ctrl+S", and the software does the rest. Do that once, maybe twice (any more and you're really pushing things) on any one shot, and you're done. Cropping is also really fast and easy with IRFanview. Be sure to install the plug-ins as well if you get it...

Thank you! I will check into that. I think that would help a lot.
