<p>Hi John, I noticed that too. I don't know much about EXIF data, I just started looking at it yesterday. I took it to mean that at the set focal length (50mm for both lenses) the max aperture available was the number given. The max aperture on the 18-105 3.5/5.6 at 50mm is 4.92 since the max aperture changes with focal length. Obviously the max aperture for the 1.4 prime is 1.4. Is that correct about the max aperture EXIF data?<br /><br />Andreas, is there an article from Mr. Rockwell I can read about the aperture? It makes sense, since the aperture isn't actually adjusted until the picture is taken. I did not notice a way to adjust exposure compensation in Auto mode. That's all my wife is going to use to take pictures of our twin babies, so I need a solution for the Auto setting.</p>

<p>Thanks for the responses. Here are links to 2 pictures that I took. Both set to 50mm, exposure meter indicated a correct exposure (ISO, shutter speed, and aperture happened to be the same for each picture). No flash used.<br /><a href="http://www.burrowspestcontrol.com/jason/DSC_0239.JPG">http://www.burrowspestcontrol.com/jason/DSC_0239.JPG</a><br /><a href="http://www.burrowspestcontrol.com/jason/DSC_0240.JPG">http://www.burrowspestcontrol.com/jason/DSC_0240.JPG</a></p>

<p>Here are 2 more, using the flash.<br>

<p >Hi, new here, hope this is the right place. I am new to DSLR cameras, and only have experience using point and shoot cameras set to auto.</p>

<p > </p>

<p >I recently bought a used D80 from a friend. Came with SB600 flash and Nikkor 50mm 1.4 prime lens. I ordered a new Nikkor 18-105 3.5/5.6 lens from B&H. </p>

<p > </p>

<p >I borrowed the camera for about a month before I bought it. Took great pics, which is why I bought it. I just received the 18-105 lens last week. Almost all of my pictures using the 18-105 lens come out underexposed and dark. I did a few tests using the flash and not using the flash. I set the 18-105 lens to 50mm, and took a picture of an object with both lenses. Most of the time, the aperture and shutter speed were the same (ISO never changed during the tests). Regardless, the exposure meter in the viewfinder would show a correct exposure (no bars to the right or left of center on the meter). Every time, the picture taken with the 18-105 comes out noticeably darker. Dark enough that I don’t even like the picture.</p>

<p > </p>

<p >In my tests, nothing changed between pictures other than the lens (that I am aware of). Is this normal? Shouldn’t a TTL meter account for any lens differences and note so accordingly on the meter display?</p>

<p > </p>

<p >The tests I performed were done on Auto and Manual. Both set of tests give the same results: a dark picture from the 18-105 lens. My wife will be using this camera pretty much on Auto only, which is why I tested on that setting. I have started using manual for just about everything.</p>

<p >Any help is appreciated. Thanks.</p>
