Is this an FX lens or just DX

Though this lens will cover the imaging sensor of a full-frame DSLR, it is better optimized for use with DSLRs containing smaller APS-C format sensors. As such you might notice softer focus and some light fall-off towards the edges of the frame when using a full-frame DSLR. If you do plan on using this lens with a full-frame DSLR we recommend you set the lens no wider (faster) than f/8 for optimum image quality.

I use on an fx body - d800. You could probably use on a dx body but it would cropped and therefor not be optimal. Also note that whatever body you use this on it is a manual focus only.

I have tested this on a FX body and indeed it is a true FX lens. To get the focus just right, you can use Live View mode and magnify the area you want in focus, and then take the photo.

It is a DX lens and will work on your camera because it works on my D600. I have a friend who thinks you should only use FX lens but my wife and I love this lens and it gives great quality photos!

Yes. but you'll get a DX crop. Since I don't know which FX body, I can't say what you're pixel count would be (D800 , I think it goes to 15.4mp, D600, I think the DX crop is a bit over 10mp). Hope this helps and best of luck. Oh, Sigma does make a couple of 24-70mm lens (one with a ring motor, one without) for FX bodies, so you might look in that direction as well. Cheers.

It is a FX lens, that is full format. I do not see why it would not be compatible with a DX body like the D7000. Nikon USA site says, answering a similar question about the D200 and The D300, that Yes this lens is compatible with these 2 cameras.

Yes. I sold my Nikon 7000 and bought this 600 as this full frame camera.But, the FX lens that you use will be expensive than DX lens.

Look into the metabones speed poster for Nikon mount instead. An FX lens is for full frame so there is a crop factor. The metabones coverts your lens to FX and also increases you F stop by one.

No...this lens is terrific with DX cameras like my D7000...but since this is a DX lens could work in a FX body, but you would waste your money with this lens using in a FX body...I would recommend use an FX lens an a Dx body rather than a Dx lens in a FX body,,,in that case, you should look for a sigma DG lens that are for FX bodies or look for an FX lens from Nikon....however, the tag price for those lens will be double or triple compared with Dx counterpart....my advice...get an DG or FX lens...i keep my 17-70mm for my d7000, but in my D600 I use 50mm 1.8g, the 70-300mm Vr, the 24-85VR and the 85mm 1.8 G....FX lens in FX bodies....hpe that helps..

To expand on another response, the most critical difference is the FX vs DX. That means that the image sensor on the FX (full frame) is larger and able to capture a greater area compared to a DX (digital, cropped frame.) Full frame lenses can be used on a DX camera, but it is a waste because the sensor can't see all of the image projected by the lens. Imagine the way looking through a toilet paper roll limits your angle of view, as an example of how this works. Putting a DX lens on an FX camera is possible, but the sensor is a greater area than the projected image, meaning the periphery of the picture would be blank. If you are a hobbyist, you probably don't need the full frame camera (nor the expense of it or the lenses required to get the most out of it.) The D610 is an upgrade from the d7100, but for the price to be worth it, you need to have a full frame lens.

you should be able too. It is designed for nikon F mounts. both dx and fx lens do use that. HOWEVER, if your lenses are digital (ie: no manual aperture control) or you rely heavily on auto focus. this will not work. NO ELECTRONIC APERTURE OR AUTOFOCUS

The lens that I bought was for a D5200 . Dx mount. It works on my D7100 also.Like I said Dx mount not Fx.

It was a DX and works well with the autofocus. I have used it for sports and nature. Need light for the sports photos to get a clear shot but I love it.

I'm not sure what FX or DX is. YOu should be able to find out all you want about the K20D at www.dpreview.com/reviews/pentaxk20d Good Luck

This lens is not designed for an FX bodied camera. While it should function with the FX camera, the camera will likely adjust to DX mode (cropping the image like a DX camera does), or if it doesn't do that you will likely get vignetting at the wider settings.

It is a DX lens...works great on my D7000 & D90....sharp and beautiful color.

Yes, this lens is mainly for FX cameras however works great on DX cameras like the D7000 just be aware that the focal length in DX is not 200mm because of the crop factor, anyway works great almost same as the Nikon but half price

This lens is considered a DX lens specifically made for Nikon's DX cameras. The D610 is a full frame (FX) camera. You can use this lens but you won't be using the full sensor size. While this lens is excellent, I'd recommend one that is an FX compatible lens.

I think you just picked up the DX somewhere. The lens is DX with or without that in the seller's description. Note though that the new model is a VRII.
