Which Lens? Nikkon 50mm AF or 40mm AF-S DX?

So I have tow very similar lenses (see below), I can't decide which one to keep and am pretty new to photography, so my question to PH is, which lens should I keep & why?

Incidentally, this is not my only lens, Id like to keep the one that would be best for close-up/portrait photography, I also have a 18-140 & a 55-300mm lens for general and telephoto pictures.

Thanks in advance :thumpup:

Id sell the 50mm as I think its a bit over rated and I never used mine at all.

Links not working. But a 40mm f2.8 macro lens is probably more useful than a 50mm f1.8, unless you really need f1.8.

The answer is, it depends !

40mm f2.8 for close up food, product and nature shots.

50mm for low light portraiture.

Generally speaking, a wider lens is more useful as an "only" lens for general purpose and a longer lens is more flattering to people and produces nicer bokeh.

There is not a huge difference between them though...the 50mm works best stopped down to f2.8 anyway !

Personally I like the 35mm DX f1.8.

Depends on the camera. Are you using a DX or full frame camera?

f1.8 is a full two stops quicker than f2.8.

It would need to be f/1.4 to be two full stops quicker than f/2.8.

Nikon D7100 Camera so not full frame!

Thanks for the answers though, decided to sell the 50mm lens
