I am a newbie with a d5100. I don't understand how some reviews say it is autofocus, &amp; some say it is not?

The D5100 only autofocuses with the latest AF-S lens, and also older professional AF-I lens. Briefly, AF-S lens have a built-in motor to drive the focusing mechanisms on the lens, whereas AF lens rely on the motor in the camera body (like the D90 or the D7000). Most traditional screw-drive AF lenses will not autofocus on the D5100, but will autofocus on the D90/D7000. Lens that say "AF-S," will autofocus with the d5100, and most lenses sold today for the D5100 are AF-S. The D5100 has no internal autofocus motor, so it will not autofocus with original-style screw-drive AF lenses. This is why some lens will autofocus with the D5100, and some won't.

You need the second Version of the tokina 11-16mm to have auto focus. The D5100 does not have a focus motor.

You need to use auto focus if you don't want to manually focus in and out on close ups or long distance shots. It sounds like you zoomed to fast and it couldn't adjust fast enough or you have it set to some weird manual setting. This happened to me that's why I am trying to offer advice.

I don't know about the d7000 but with the d5100 you have to manually focus cause it doesn't autofocus since there is no motor in the cameras body

I have a D5100 just set the focus square where you want it and it will focus. The lens must be in auto not manual.

Thanks, Philip. I kept mine, still really pleased. Learned that shooting in "Auto" is my best friend right now (clear crisp photos at any distance from macro to nearly all zoom), but glad to hear the "shaken when stirred" is not a sign of something wrong, or about to go wrong. Best wishes.

This lens does not have an auto focus motor in it. (i have a d90 which has an auto focus motor, in turn controls the lack of the focus motor in this lens, which makes the set up between camera and lens have auto focus)Your camera, the D5100 Does NOT have an auto focus motor, so you CANNOT have auto focus with a non motored lens.So solution:You need to get a lens that has a auto focus motor in it. (like Rochelle answered) (the 1.8G has the motor you need)If you get the 1.8D lens, you will only have manual focus.with the 1.8G you will have both auto and manual focus.hope it helps:))) This lens does not have an auto focus motor in it.

The camera only has good quality auto focus when in the fully automatic mode. When using other programs the auto focus mode is not a top priority feature for the software. The auto focus takes a while to adjust the more you use the zoom feature. I love the camera. I own several high end Nikon SLR's but have more fun with this unit. There are several good books available from Amazon which are excellent on explaining the many features of the camera.

You asked this same question some months ago regarding one of the other mid-price-range nikons. We did a little research and discovered that it will not autofocus with this body but it will do everything else. You will have to do your own research this time. My guess is that it will not autofocus with the D50 but..........inherently, ultrawides have a super deep depth of field and so you might find that you do not need autofocus at all.

I had the Nikon for 4 months now and I like it. It is pretty sharp, not too heavy and works great. The VR works well too, it makes a difference. Here is a link to some photos with a D7000 which has a similar sensor to the D5100. http://www.pixoto.com/ralhaj/recent hope this helps

It works well on my D5100 which is essentially the same. But with no metering and manual focus. Just put the mode to "M" and shoot a test shots until the exposure is right. Takes great pictures, if you remember that it will be a little soft when wide open. It makes a great portrait lens because of the way it isolates the background.

Look for the obvious, first:Check for smudges on the lens when it's out.Watch the shutter speed (the bottom-left number when the shutter button is half-down) and don't take a picture unless it's over 60.Make sure it's set to "AUTO(1600)" instead of "AUTO(400)" so that it can use higher shutter speeds.Make sure you have the autofocus set to "center" and then aim at your target.I've taken about 600 photos with this camera so far and they're all exceptional. This is easily the best camera I've owned. One thing that I've realized about it, however, is that if I lacked an understanding of the essentials of SLR photography, this might be a difficult unit to operate. So consider the above a primer. :) Look for the obvious, first:Check for smudges on the lens when it's out.Watch the shutter speed (the bottom-left number when the shutter button is half-down) and don't take a picture unless it's over 60.Make sure it's set to "AUTO(1600)" instead of "AUTO(400)" so that it can use higher shutter speeds.Make sure you have the autofocus set to "center" and then aim at your target.I've taken about 600 photos with this camera so far and they're all exceptional.

AutoFocus was fine. Some circumstances, e.g., bird watching, require manual focus.

No not in auto-focus only in manual. I really prefer to focus mine in manual anyway now, just takes a little practice and you will be shooting like a pro in no time. I had one just like this and got broken but am getting another as takes great shots.

With my D90 in manual or aperture mode, it does require a center focal point. Not sure about other modes. I tried "auto" a couple of times and the laser fired every time regardless of where the focus point was. Don't take this as conclusive information. I'm fairly new at this and it may be camera/lens dependent.

I use this lens on a D7000 and get excellent results, especially with auto focusing when shooting birds in flight. However, regarding your inquiry about the D5100 be aware that the user's manual for the lens (Nikkor ED 80-400mm F/4.5-5.6D) states on p. 15, "Autofocus is not possible with Nikon' D5000, D3000, D60 and D40-Series cameras. When using the lens with these models, set camera focus mode to M." I believe that the D5100 has the same autofocus limitation as the D5000.

On the D5100 the Nikon 50 mm f/1.8D will not autofocus. You will need to purchase the "G" version for autofocus on the D5100. Only lenses with the designation AFS will autofocus on the D5100 which does not have a motor in its body. With respect to 50mm vs 35 mm you may find that the 50 has too much reach for normal use on the D5100 which is not a full frame DSLR. On the other hand it will work reasonably well as a portrait lens since it will have an equivalent reach of 75 mm on the D5100. Both the 35mm and 50 mm "G" lenses will produce images of roughly equal sharpness.
