Fee error on d300 with Sigma lens with aperture ring


Turn the aperture ring on the lens to its smallest setting (largest f/number) and then forget it's there. You can control the aperture from the camera body, the same way as on lenses without an aperture ring.

Why the "f" number in manual mode, doesn't go to under the 5.6 ?


f/5.6 is the maximum aperture for the 18-55mm lens zoomed in to 55mm. If you zoom out to 18mm you'll be able to open the aperture to f/3.5.

The maximum aperture is a matter of physics. The larger the aperture (smaller f/numbers) the larger the lens has to be. In theory you could make a 55mm lens with a maximum aperture of f/0.5, but it would have to be more than four inches across on the inside. Lens designers have to balance cost and size with performance.

If you really need a faster lens you can get something like this, but it'll cost you a bundle, about six times as much as your 18-55mm.

I would like to set at the largest aperture. I have an aperture of 5.6 but I know I can get a larger aperture can you tell me how? thanks


The aperture can't be larger than the number printed on the lens. For example, if your lens says it's an 1:3.8 - 5.6, then the aperture can't be larger than f3.8. Since your lens is a zoom lens, it can only open that far at the 18mm setting. The farther you zoom out, the smaller the aperture will get.

I used the Nikon D90 with Lens Kit 18-200 mm, and I also bought the new Lens call Nikkor 75-300mm. But when I connected the new one (Nikkor 75-300 mm) in my camera and took some pictures, after that I...


That's the Nikon error message for a lens with aperture ring set to something other than the minimum (i.e. highest number).
The camera insists on controlling the aperture ring, and to do so, the ring must be set to the minimum setting.
Unless it is a "G" lens, which has no aperture ring whatsoever.
The camera body sets the aperture of the lens wide open while auto-focusing, and displaying through the viewfinder. When it comes time to flip the mirror up and take a picture, the camera dials the aperture to the setting you (or the camera) have selected.

Changing the f stop on lumex 10 meg


One of the problems with a point&shoot camera is that you can point and shoot but not all that much more.

The DMC-LZ2 doesn't give you direct control over the aperture. You can get a smaller aperture (larger f/number) by using the scenery mode, or a larger aperture (smaller f/number) by using the portrait or sports modes.

Why won't my aperture go lower than 5.6?


You do have total control, within the constraints of the hardware. The 18-55mm lens has a maximum aperture range of f/3.5 to f/5.6. This means that at 55mm the maximum aperture is f/5.6. You can go the other way, all the way to f/38. At shorter focal lengths you can open up as far as f/3.5.

If you want a larger aperture, you'll have to get a faster lens. For example, Nikon has a 17-55mm f/2.8 lens which has a maximum aperture of f/2.8 at all focal lengths. It also costs $1300 new.

I HAVE THE SAME PROBLEM.


If you're using the kit lens (17-85mm f/4-5.6), the maximum aperture achieveable when fully zoomed out (wide) is f/4 and when fully zoomed in, f/5.6 (that's what the f/4-5.6 stands for). The minimum aperture on this lens is not a problem since you're only making it smaller. i.e., f/22.

Try zooming back and turning the Aperture adjustment dial. You should be able to get f/4.

If you need bigger aperture to get a nice bokeh or to take portraits where the background is blurred while the subject in focus (aka shallow Depth of Field), try lens that are f/3.5 or f/2.8 max. The Canon 50mm f/1.8 is quite affordable (around US$100-120).

I would just like to find out how to set aperture when shooting in manual mode


The REBEL is Either aperture or shutter priority.

You can set this up via the menu

There is a rule of thumb and it also depends on the ISO ( ASA or film speed) iF IN LOW LIGHT USE A HIGHER ISO say 200-1000

and an aperture set from ap ring on lens a good all round setting is F8

the rule for Apertures is smaller the number larger the aperture ( lets more light in, but in high iso settings you really dont need to change this unless its really dark,

Larger the number smaller the aperture used for very bright light conditions, where over exposure is likely to occur ( even in flash )

Flash automatically uses F8 but this is not always ideal as when shooting in some lights at a white object ( wedding) the pic will be overexposed , sometimes its better to use F11 with a flash and an ISO of 100. Perhaps you need to get an easy photo guide book Digital Photogreaphy for Dummies ( no insult intended) It has a lot of these little tips in it and will improve your pics beyond "Happy Snaps"

Changing the exposure is to use the aperture ring on the lense most are from F2-F22 depending on the focal length of the lens say 50 mm 150mm - 200mm for each size lens one would increase the F stop by 1 or add and EV point (+01) to compensate for the length.

Nikon 50mm 1.8 lens error message


Hello,
The 50mm lens is fairly old and uses a different system to the later lenses. On the D90 and other later cameras you should rotate the ring to 22 and lock it there using the lock just above the aperture ring.
To adjust the aperture you use the front dial by the on/of switch.

Try it out in A mode. Rotate the mode dial on the top left of the camera to A (Aperture Priority mode) then lightly press the shutter button to turn the meter on. Then rotate the front dial and you will see the aperture reading changing.

The older Nikons changed their apertures using the ring but the later Nikons use the camera controls.

Blue tint when shooting aperture priority


Hello, First of all let's explain what aperture priority does in terms of electronics and mechanical/optical changes in the way the camera takes photos. Unlike most point and shot digital cameras, your one has variable aperture range. Aperture is related to your camera lens. Their main function will be to collect light and direct it to the camera's sensor. The aperture of a lens is the diameter of the lens opening and is usually controlled by an iris.The larger the diameter of the aperture, the more light reaches the image sensor. Aperture is expressed as "F-stop", for example F2.8 or f/2.8. The smaller the F-stop number (or f/value) the larger the lens opening (aperture). This means that when you're using aperture priority or large aperture values (a smaller f/value) your image sensor (ccd or cmos) will tend to receive more light or slightly overexpose itself. Most simple digital cameras, the point and shot ones, have a fixed aperture, the lens are fixed and that's set to a so believed "optimum" range in order to produce best pictures when using automatic settings. SLR or semi SLR digital camera's woun't achieve best performances when using them on automatic settings, they aren't designed in the same way as the simple camera's. These camera's will tend to either overexpose, or have lighting/colour problems or achieve blurry images when using automatic settings. Any SLR or semi SLR camera user will be required to understand the way photography (electronic photography) works in order to achieve the best performances with it's camera. For your example, I guess the shots have a blue tint on them when you're using natural sun light in your photos, or in room pictures are illuminated by natural sun light. This is the first sign of overexpure, and the best way to reduce it and it's efects is to manually set the aperture range. Note that higher values will reduce the light that passes to the sensor, so you will want to experiment a little with those in order to achieve the best performance. When you take photos in light environments, bright sunny days or in rooms that contain many white surfaces or walls (these reflect the light pretty much and can overexpose the camera even if it doesn't look that bright when you look at them with your own eyes) you may want to use larger aperture value in order to have little light come to the sensor. Look for the highest values in aperture (in your menu) for example F8 or F16. If the pictures come out to dark or miss some details, you may want to use larger apertures (smaller numbers). Try these tests in order to check if your camera's problem can be solved this way. If not please reply back and we will look on the hardware - firmware side of the problem. Regarding aperture a quick recap :) A large aperture allows more light to reach the sensor. It's good when taking portret pictures and also achieves that nice blurry background surrounding your main subject in the picture. It's defined by smaller numbers (for example F1.8 or F1.2 or smaller). A small aperture allows little light to reach the sensor. It's good to take pictures in bright sun light. It's defined by larger numers (for example F16 or F22 or larger). Hope this helps, Bogdan.
