Did you try to adjust focus? in the Setup menu also page I assume. you need a focus test chart. (can be downloaded from the net, just google for (FocusTestChart)

SOURCE: aperture priority only in manual mode?

Yes. You pick the apature (the 3000 keeps it aorund the setting you pick) and then it automaticly adjusts the speed for you.

SOURCE: 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.

SOURCE: Sigma 170-500mm APO lens on Nikon D50 won't autofocus or shoot

When you get a flashing EE, it means there is an Eror somewhere. Most cameras have a botton you press to reset it. Usually it is the battery check button. Try that. Also try taking the lens off the camera, unlocking the aperture ring, remount the lens and then lock the aprture ring to the minimum F stop. I think this should solve the problem.

SOURCE: Aperture priority not working...HELP!!

Hey Mike, This is an easy one. With the battery grip attached, you can only have either Shutter Priority or Aperture Priority work properly. You can change it with the custom function settings of the camera. So you can change it to work with Aperture Priority if you use that more so then shutter priority won't work. Brandon

SOURCE: slr e 500 can you advise on the best technique to

First of all this is a big subject that you cannot learn from just a few lines of infomation. If you are interested to work professionally ,then it is better to attend a full time or part time course in professional photography that is run by various institutions. You will need practical coaching , guidance and taught fundementally the subject. Once you under the technics of the cameras-- digital or celluloid- the variation of the shutter speed, the aperture settings , the angles of focus, lighting , all this needs a certain degree of combination that makes you a professional photographer.

I do not get a sharp focus with macro enabled on my sigma 70-300 DG lens

A lot will depend on how close you are to the subject. If you are at maximum lens length 300mm and you are not getting a sharp pic, try leaving the lens at 300mm then bodily move the camera and lens backwards away from the subject or closer to the subject until you see it become sharp in the viewfinder.

My lens is not getting the image sharp and the motor of the lens is making a strange noise.

The autofocus motors in Sigma lenses that are not HSM tend to be noisy, but I presume yours is now more noisy than usual. With that, and not focusing properly, considered together, It seems to me the motor has failed or the lens parts have partially seized causing the motor to "struggle" to focus parts that are not moving as they should. I.e., once focused the motor will stop, but if the electronics are telling the motor the lens is not if focus, it will continue to try to achieve focus. Most likely, time for repair, and if in warranty, contact Sigma repair via Sigmaphoto.com.

I now use this lens on Nikon N5005 and want to purchase the D5000 camera. Is this lens compatible?

Yes and no. The lens will fit on the D5000 without a problem. But the sensor on the D5000 is smaller than a frame of 35mm film so you'll end up using only the center portion of the image. What this amounts to is that the lens will act like a 115-450 zoom would on the N5005. Also, if the lens doesn't have a focus motor built in (Sigma calls it HSM) then it won't autofocus on the D5000. You can still focus manually, though.

I have a Sigma 400mm APO HSM Tele macro lens that I am most pleased with. It takes amazingly sharp pics, even wide open, that I am forced to do because I cannot get a re-chip done. My problem is that...

Sorry, but it's not a DIY fix as the lens will need to be collimated. Without this, you'll just be guessing the correct position and alignment for the loose optical element and won't get your image quality back.

Professional repair and re-collimation will not be cheap though and the lens may not fully recover its former sharpness, so it may be time to let your faithful friend go.

I hope my answer has assisted you in choosing a course of action; please take a moment to rate my reply.

It could be condensation inside the lens. It could be a problem with the focusing. It could be other mechanical/optical problems with the Sigma lens. If the problem persists after the lens has thoroughly dried out, take it in to a reputable camera shop and have it checked out by a qualified technician.

My husband has a Nikon F65 NON-digital camera for which he has an APO sigma 170-500mm lens. I am thinking of purchasing a digital camera for him (Nikon D50). Will this sigma lens be compatible? Are lenses...

Yes, the lens will be compatible with the D50.

All lenses are optical: light comes in one end and goes out the other. There's no digital/non-digital about it.

What there is about lenses is the size of the image circle. Lenses cover a certain area. A lens that covers a 35mm film frame, such as the Sigma under discussion, will also cover a smaller area, such as the sensor on a D50. It's possible to design lenses with a smaller image circle. These smaller, lighter lenses are sometimes called "digital," because they are intended to only cover the typically smaller digital sensor. Using such a lens on a full-frame or film camera will produce dark corners. This is NOT an issue in your case.

How do you use the manual focus feature. My friend just bought a new one and is having trouble with this part of the lens. I have one for my canon and there is a setting for it

Set either the camera or lens (or both) to manual focus. Most Nikon cameras have the focus selector switch on the front, under the lens release button.

Look through the viewfinder and turn the focus ring until the image (or at least the subject) appears sharp. A green light will light up when the camera thinks the subject under the currently selected focus sensor is sharp.
