fx format and older lens
Jan 10, 2015 21:30:20 #
I have read that fx and 35mm film are quite similar, so with that being said are older lens from film cameras compatable with fx format? And also how does one tell the difference between a DX lens and an fx lens? I have seen both offered at places like eBay but looking at the pics of both I see no difference, I was told by one person u have to look at back glass. Tnx in advance

DX & FX are Nikon terms, describing different size camera sensors. All FX lenses will work nicely on either the full frame FX (36 x 24-mm) camera, or the smaller DX (24 x 16-mm) camera. DX lenses will fit on FX cameras, but corner vignetting will most likely occur. Older, film-era lenses will work on either format.

Careful with canon ef vs ef-s lenses may damage camera or lens

tnx Nikonian72 for the link provided very good example, but if u were to lay for example a nikon 80 to 400 f4.5to 5.6 in both dx and fx side by side how would one determine which is which. tnx

DX lenses say DX in the lens title on the lens.

On a Nikon lens, if it is DX than it will say DX on the body. All older FX lens work on FX and DX cameras. May not auto focus and may not meter, depends on the lens model and body combination.

I use lenses that are up to 40 years old on my D700. One must be careful as some of the older lens designs have bits that will remove or damage the electrical contacts on the camera body.

The differences in using FX lenses on a DX body are that the camera then senses the lens and the sensor adds the multiplication factor in, say 1.5 or 6 on the Nikon. Vice Versa when using a DX lens on the FX body. The contacts signal the FX body that this is a DX lens and only the central portion of the lens is used with the sensor acting as an DX sensor. You won't get vignetting in the photo, in the viewfinder maybe but not the photo.

A valid point, though the crop factor is simply caused by a smaller active sensor area. The camera does no mathematical calculations to get there. For the FAQ, the DX detection was turned off in the full frame camera to demonstrate the actual image coverage. Some people use their cameras this way. At some focal lengths they will get full sensor coverage with a DX lens, though I would bet the corner sharpness suffers a bit. In DX mode on a full-frame camera, you lose a bit over half the resolution.

When I bought my first Nikon DSLR (D300), I couldn't afford new lenses. For a year I used the older autofocus lenses that I had used with my Nikon N90s. They worked fine and the Nikon lenses were just as sharp on the 300 as they had been on the D90s. They did not have motors in the lenses but the D300 did and so therefore were totally compatible with the autofocus system. Those lenses used on the smaller Nikons D3000 and 5000 series would have to be manually focused.

I have some older AFD and AF Nikkors that I use on my F4S & my Df as well, all is well. I even use the 50 mm f/1.4 Nikkor SC lens that I bought with my first Nikon, an Nikon F, Photomic T that I bought in 65. I have some great MF Nikkor lenses and have used them on my D1X & D2h as well.

fx and 35mm film have nothing in common. the fx refers to the size of sensor. the results will always be inferior to the 35mm negative. fx is simply better than dx (aps film size). so go with a nikon f6 film camera, you will never regret it!

Unfortunately, then you have the issue of digitizing the resulting negatives or slides. I got rid of my F 100 & F 5 cameras because they lacked the flip up ADR lever that my F4S has as well as lacking matrix metering on the oldest lenses.
