Hi everyone

New here! Just looking for some advice really as still fairly new to this.

I have the Nikon D3400 which I am very happy with, but just learning about DX and FX cameras.

The D3400 is a DX so therefore the lens lengths aren’t exactly what they say on the tin. I have the 35mm prime lens, but due to the camera type it behaves more like a 50mm in terms of what you get in the image.

I like to do city breaks and landscapes where I travel, but I am finding myself struggling to fit what I want into my pictures without having to move back and end up standing in the road for example!

The 35mm DX lens came highly recommended and it’s quality is superb in the pictures I do get. But do I need to go for a 24mm prime lens for my DX camera so that I can get the shots I want as it’ll be closer to an actual 35mm length? Is the quality of the images on that lens going to be compromised? I haven’t been able to find much info on it. Or is there another lens that would be ideal?

Any advice from a more experienced voice would be great !

Thank you !

Hello,

If you have a single format (DX/FX/..) I wouldn’t bother much about comparing the crop factor, unless you see a picture taken on another format and you think you want to have the same field of view.

However it is good to know that the crop factor of the sensor has an impact on the field of view.

Also, the focal length information on a lens is correct (i.e. a 35mm is a 35mm both on DX and FX aimed lenses, it is the sensor size that impacts on the field of view)

As you mention in the other discussion that you also have the 18-55mm kit lens, the question to ask yourself is to find out at what focal length you are taking most captures, if you are looking for a prime lens.
With the zoom lens you can set it to 24mm and check whether you like the field of view that you get. Same goes for other focal lenghts in the range of your zoom.
If you find yourself using the 18mm focal length and still want a larger field of view, only look for a 10-20mm.

As regards a 10-20mm zoom, I think there are currently two good lenses DX lenses in the market, the slightly older Sigma 10-20/3.5 and the more recent Nikon AFP 10-20/4.5-5.6.

I use the 10-20mm AF-P on my D7500 and am quite happy with the images it produces. It's not as fast as the Sigma 10-20mm f/3.5 but it does have Vibration Reduction (VR) and is considerably lighter.
