I am being really thick I'm sure, but I cannot get my camera to go below f4.5.

In my defense I am relatively new to all of this and am learning by trial and error (more error than anything!)

I have the original Nikon lens kit and a Tamron 18-270 f3.5-6.3. No matter how I zoom, or not or what settings I use, it will not go below 4.5. What am I doing wrong PLEASE tell me.

Thanks in advance for any advice

I'm not quite sure how to answer this, but I have the same camera. And the problem I'm having is that the camera will NOT autofocus when I'm using my Nikon image de-focus control lenses. Very frustrating indeed! I got this camera instead of the D700, or the D7000, or whichever camera has the same megapixesl. And I got it because it's much less expensive than that other camera, but I'm starting to wonder if I made a mistake? I have no clue as to the capabilities of that other Nikon. I love the image quality of my D5100 camera, but that's about all I like about it.

In addition, when I use my Nikon built flash unit - I foget which model, the camera automatically sets the shutter speed at the highest sync speed, as if that's what I planned to do! NOT! That might be ok outside in full sunshine when I want to elimiate shadows on a person's face, but it hardly allows for much ambient light use in semi dark interiors! It seems like the only solution sometimes is to put the camera in total manual operation, and use an incident light meter!

Welcome to Nikon entry level cameras. Your defocus lens requires the camera to have a built in focus motor...the d5000 series does not have this motor and will never focus with these types of lenses. I think Nikon has done us a disservice others here don't seem to mind. You can only auto focus with afs or afi lenses.

A disservice? How silly is THAT statement.

Do proper research, and buy the camera you need. Duh.

Hard to say. Put your camera in A mode, zoom all the way out (wide end), and spin the control wheel. Should be able to get to f/3.5.
 
First Franypans problem. (Scott you better start a new thread with your problems. It's different.)

Better read the manual and even some more publications about the camera like The Nikon D5100 Experience by Doug Klosterman. But before we can help we need more info.

-How long have you been trying? Just today or a couple of weeks?

-What are the light conditions? Inside or outside?

-Is it with both lenses?

-What settings do you use? P, A, S, M, Auto, Scene?

-What ISO setting?

-Have you set the exposure compensation [+/-]?

-Are the images well-exposed?

Your lens will only reach the widest aperture at the widest focal length. Zoom out to 18mm and you should have access to f3.5.

You bought a camera without a built-in focus motor. Do your research better next time.
In addition, when I use my Nikon built flash unit - I foget which model, the camera automatically sets the shutter speed at the highest sync speed, as if that's what I planned to do! NOT!

Hard to say what's going on with your flash, because you haven't given enough info, such as what mode you're shooting in, etc. You should upload and post a photo here with full EXIF data intact, and be sure to set your profile to "allow download of original". Then maybe we can get to the bottom of it.

I did do research and did get the camera that I wanted. But, unlike some here, I can empathize with those that don't spend all their time reading manuals, photo-blogs, and forums like us. There is a reason that we see questions like this nearly everyday....it is a perfectly reasonable assumption that a Nikon camera will work with a Nikon lens! I swear some of you guys get a sadistic glee when someone misses this particular bit of fine print. Let's all laugh and shout , RTFM!

Really? Wow.

I've only been into this "hobby" for about 3 years. When I bought my first DSLR (a D80), you can be darn sure I educated myself a bit before I actually dropped the $$$ on something. Seems pretty logical to me, this is not rocket science. I would do the same thing with any product I had interest in.




Is it a disservice when someone buys a microwave, and the manufacturer didn't put a "popcorn" button on that particular model?

No, but it would be if I could only plug it in in the Ukraine. I'm sure if I posted a complaint on a microwave forum some smart ass would tell me to do my research.

This stuff may be common knowledge here to us but it's not out there in the world of a casual user. It's buried deep in the manual, I don't think it's even on the box. Certainly nothing that comes up in a big box store or on the front page of Amazon.

Sorry, but I have to disagree. Like I said, I was new to all of this 3 years ago, and the reason I decided on the D80 was largely because it had an internal focus motor, and it wasn't as it I had to do massive amounts of research to reach that conclusion.

Of course you do, many folks here feel the same as you. Yet I'm not sure I believe what you say about not doing massive amounts of research to reach that conclusion. If you bought your first DSLR three years ago and it was a D80, you were confident enough to buy used or at least something end of life cycle. You have over 3000 posts on a camera gear forum...you read, write and think about cameras much more than the average person. Like me, you get a kick out of finding great deals on cameras and lenses (like $8 for the 50mm 1.8 AFD which is awesome by the way). I imagine you did some reading into the used lenses you investigated. You are quite clearly not the average entry level camera buyer. What you or I consider reasonable research would be considered mind numbing to a significant percentage of the population. It is perfectly reasonable for a consumer buying a Nikon DSLR to assume that a Nikon lens will work properly on it.
 
Your lens either is f/4.5 at widest or you use a focal length that has f/4.5 as maximum aperture.

In the first case there is nothing you can do but use a faster lens (that has larger max aperture). In the second just use shorter focal lengths since you perhaps have a lens that has a decreasing maximum aperture as you increase the focal length.

I missed that part of your post. It is very odd since both lenses have max aperture at widest f/3.5. In M mode you hold EC button to change aperture and the camera should let you change the aperture if you are at 18 mm to f/3.5. If you cannot get this something is wrong either with your body, the lens contacts or the lenses. As this happens with two different lenses it is unlikely that the culprit is one of the lenses. Then remains the lens contacts or the dial of the body. Since the max aperture is obtained in S mode I'd rather look at the body fault.


Are you using any kind of teleconverter?
 
I agree, If I was not a camera nerd I would assume that if the lens fits it would focus... Especially when a great deal of Nikons advertising hype was about how long they have had the F mount and how many lenses will fit (f100/F5 days)

Anyway, I bought the 5100 on a whim and it bit me as well.... I assumed since it mentioned manual mode on the feature list and I could see the M on the dial I could shoot video in manual... Not so :)

Check "EV Steps for Exposure Cntrl" in Custom Menu. This allows 1/3 stop vs 1/2 stop for EV steps. This might be the problem.

At 1/2 stop, it suppose to be 2.8, 3.3, 4, 4.8, 5.6, etc.

At 1/3 stop, it should have access to 2.8, 3.2, 3.5, 4, 4.5, 5, 5.6, etc.

I had a problem similar to this, but at the narrow aperture end. I thought it was hardware issue. Even Nikon customer service said to send the lens in. Then I figured out I had the setting on 1/2 stop. Once I change the setting to 1/3 stop, I can access the smallest aperture opening.
