Can a FX lens be used on a DX camera
Of course - if you have a Nikon. The only difference is that the fx lens is delivering an fx sized patch of light to the focal plane of the sensor, but the sensor is much smaller, so only the middle of that patch of light is recorded. This is what accounts for the 1.5 apparent telephoto effect. Another effect of less light being recorded is that the apparent f stop is larger. Your 100 mm f2 will be recording like a 150 f2.8.

Yes and you can also use a DX lens on a FX camera.
You have it reversed. The question is a FX lens on a DX camera.

Yes that was the original question, but what he says is you can use the Dx on an fx camera. The difference here is that the dx lens is optimized for a small sensor in terms of things like sharpness at the edges and light fall off at the edges. Fx lenses are optimized to keep the sharpness and light intensity constant all the way to the edges of the larger sensor, whereas the dx lenses do that only for the smaller central area of the focal plane. If you don't mind some vignetting and edge softness - as you might even desire in portraiture - using a dx on an FX camera might be just fine!

Yes. Definitely. I have both Canon types of SLR's and all of my Canon full frame lenses work on the APS-C camera as well.

It depends... On Nikon yes all can be. On Canon, ... (show quote)
First: use the terms "Full Frame," and "APS-C" FX and DX are Nikon terms.
Second: all Canon ef lenses can be used with all Canon Cameras; however, ef-s lenses, lenses designed for APS-C cameras should not be used with Canon full frame cameras, as this could result in damage to the lens and or the camera. It would also result in vignetting on any full frame camera even if the lens would mount. I would suggest that it is best not to give information when you do not know what you are talking about.

Can you explain that last sentence?

Yes. And dx as well as fx lenses can be used on many other cameras as well, like Sony and many m4/3 cameras and cameras with cx sensors. But for those you will nerd adapter.

Well, I didn't know that about the 7100 and the 7200. Thank you for the information. What type of Ai lens support do get with D7200- besides the green light that indicates proper focus, and aperture priority? And what would be a ballpark price for D7200 these days?
LOL ball park price for a D7200 would depend, at Adorama (with add ons like their accessory bundle about 1196 body only) At B&H New with accessory bundle (INCLUDES FREE ▪ SanDisk 16GB Extreme UHS-I U3 SDHC Memory Card (Class 10) ▪ Ruggard Commando 36 DSLR Shoulder Bag ▪ Watson EN-EL15 Lithium-Ion Battery Pack (7.0V, 1800mAh) $1496 Note: the B&H bundle looks more usable than the Adorama on. I didn't see refubished but I am sure that they are available. Also, check Cametta or any number of other authorized dealers.. they don't discount but they add accessories to the retail package to "hide a discount" in the regular price. So you just have to shop for the best bundle at regular camera price. Other than the larger buffer on the D7200 and increased sensitivity on the sensor, it is very similar to the D7100 and you might get better discounts there if you are intersted. As for the green focus / red out, my D7100 has a red box out of focus that turns black in focus.. and, of course in manual focus it is always black regardless of where the focus is set. But, I have my camera set to back button focus. I only have one green light and that is the memory card access lamp/ That light is on the back of the body under the focus selector lock. The over / under exposure arrows and the other readouts are white on black across the botom of the viewfinder.

That video is bizarre. It makes me think the guy is on drugs or something. It's a nice touch to have all kinds of cameras laying about, gives you the impression he's experienced. It's a nice tough to put the key points on a placard, makes people think that these things are actual facts.
In the end it's all crap. Why do we allow such people on the net? They create nothing but confusion in those who want and need to learn.
