What is the difference between fx and dx format

The times when you might want to consider a DX lens over an FX lens for a DX format camera are when you consider wide angle options. Due to the crop factor discussed above, wide angle DX lenses are generally cheaper than equivalent wide angle FX lenses because of the design. Due to the crop factor, the common kit lenses also look different in terms of price and focal lengths for each format. Kit lenses for DX cameras are typically lenses like the mm and mm lenses.

Advanced users may prefer to spend more money on a higher quality FX format lens to use with a DX format camera due to the overall quality of glass in the lens; however, that is a discussion for another day.

Essentially, DX Crop Mode avoids the heavy vignetting that we would otherwise experience when using a DX lens on an FX camera by only recording the image using a smaller section in the center of the sensor.

Of course, this results in an image with a reduced resolution. Not a bad trade-off at all. Nikon DX lenses are generally smaller and lighter than Nikon FX lenses because less glass and a smaller lens barrel is required to produce an equivalent field of view for a lens that goes on an DX camera, like the Nikon D and D lines, when compared to a full frame camera.

Additionally, as mentioned above, the DX line of lenses are generally more affordable. Hopefully, you are now aware of which Nikon lenses are compatible with your camera. As to which lens you should buy, my suggestion is to buy the one that fits your needs. Quality DX lenses hold their resale value just fine. Buy the lens that fits your needs now. If that means you want a massive FX telephoto lens, then go ahead.

If you upgrade to a full frame camera later, it will work fine as well. Generally speaking most 50mm prime lenses are made for FX or full frame cameras, whichever brand.

With a Nikon camera, except the series, series and a few others like the D will work with the Nikon 50mm f1. Its resolution is superb and on a DX camera it equates to a 75mm f1.

Mostly Nikon includes kit lenses of 18 — 55 and 55 — AFS lenses which have a built in focus motor in the lens, so they will work with those cameras mentioned before, whereas the AF 50mm f1. I have a couple of Ds and they have built in focus motors which is what you need to use any straight AF lenses. Great for wildlife!! Great article but I am still a bit confused. Given the article, is its effective Focal length I was told the 1.

The crop factor effect applies to both DX and FX lenses. So, you are correct that the mm lens behaves like a As a result, you still need to take the crop factor lenses into account for DX lenses. If you have got used to it, the focusing is wonderful. I also found the DM magnifying eyepiece to be very helpful — it enlarges the viewfinder image by a factor of 1. The photos — as seen above — prove the outstanding image quality of the manual, old lenses.

In addition, a not unimportant side effect — now the main argument for me — is the space savings. I take pictures almost exclusively with prime lenses. A 20mm AIS lens fits in every jacket pocket. My little photo bag is enough for a camera and 2 manual lenses — but think carefully beforehand about what should be photographed. In addition: Not a lot of hauling, but still the highest quality equipment. DX or FX?

There are SLR cameras with full-frame sensors and some with a crop factor. At Nikon cameras with full-format sensors are marked with FX, e. Here is a little comparison:. The biggest difference is that an FX sensor allows you to take photos with higher ISO values and the noise behavior is better than DX cameras. The decisive factor here is the larger sensor.

Higher ISO values are welcome wherever there is poor light and long exposure times are not possible.

A good example of this is weddings. Everyone or at least many know the following situation. You have an entry-level SLR camera DX format that takes halfway passable photos and your friends will ask you whether you could please photograph the wedding.

After a while here, you agree and the sleepless nights begin. Below are 3 methods of how you can take photographs, for example, at a wedding, and what experiences we have made with DX and FX formats over the years. You can also work with low ISO values in combination with the flash in poor lighting conditions. Unfortunately, direct lightning has its negative side effects. Here are 2 examples for a better understanding.

These photos are from the wedding of a couple who are friends. What you can see very clearly here is the shadow in the background of the bride and groom. The bridal couple is also continuously illuminated by the flash and the natural lighting mood is suppressed.

Here is a photo without an additional flash for comparison. Unfortunately, it is not exactly the same recording as we did not have time to reproduce it during the wedding, but at least it should help to show the differences.

By omitting the flash, the natural lighting mood can be used and there are no hard shadows in the background. The darker background can also be an advantage because then you emphasize the really important — the bride and groom — even more, but the following photo was taken with a Nikon D shows again what is possible with natural light:.

Of course, it always depends on which lenses you use. The only thing to say here is that you should — as far as possible — invest your money in high-speed lenses with a continuous aperture of f1.

We ourselves like to take pictures with aperture 4 on such occasions when we want to photograph individual people. However, to avoid vignetting, the DX crop mode is automatically selected by the camera when a DX lens is attached. On a full frame FX-format camera with a DX lens mounted, the camera will automatically engage its built-in DX crop mode, thus recording an image only from the center section of the sensor. Yes, FX camera bodies and lenses are full frame! The FX sensor, with more "light gathering" area, offers higher sensitivity and, generally, lower noise.

There is, of course, no crop factor present with the FX sensor with an FX or full frame lens. And here's why. Each lens is designed to cast an image circle on the camera's sensor. The circle cast by a DX lens is smaller and corresponds to the size of a DX sensor.

Non-DX lenses cast a larger image circle corresponding to an FX-format sensor. On an FX-format camera with a DX lens mounted, the camera will automatically engage its built-in DX crop mode, thus recording an image only from the center section of the sensor.
