Nikon 35mm 1.4 or 1.8 what is the difference?

I'm looking for lenses that are good for filmaking on a nikon d5300… Thanks

F/1.4 is faster than the f/1.8 and if you want great bokeh, f/1.4 is the one you should go for. If you ask me, I would still get the f/1.8.

The 35mm f/1.4 at $1,700 is a phenomenal overpriced lens: http://www.photozone.de/...rafs3514ff

At "only" $899, the Sigma 35mm f/1.4 Art lens is nearly 1/2 the cost of the Nikon and it's sharper, as well built and has better bokeh too. Now with the Sigma 35mm f/1.4 Art lens on the market, there's absolutely no reason why anyone should even consider Nikon's 35mm f/1.4.

An aperture of f/1.4 gives you 2/3 of a stop of extra light-gathering capability than f/1.8. Which may be critical if you're always shooting hand-held in low light. The f/1.4 will be sharper at all apertures compared to the f/1.8 lens. I would see about getting one used at keh.com or B&H, or eBay before buying it new.

F1.4 is a wider aperture than F1.8, but the Nikon 35mm f1.4 is ridiculously expensive. Have a look at the Sigma 18-35mm f1.8. It is for crop sensor cameras and is quite quiet when focusing.

The difference is 2/3 stop in the maximum aperture and several hundred $£€.
Because you have to ask, the 1.8 will be just fine for you.

Technically just a half-stop but out there in the field, it's a whole world of difference.

As far as film-making goes, the only difference between the two is their aperture, which is the determinant of how much light gets into the camera, which for film-making, will have an effect on the brightness. Basically, the lower the f number, the more light is allowed into the camera. It also makes for a shallow depth of field. With the f/1.4, for example, you would be getting a shallower DOF than you would with the f/1.8, which causes more blur in the parts of the scene that are not in focus. I would look into lenses that have VR (Vibration reduction) for film-making. Those will reduce the shakiness of the camera when shooting videos.
