The Nikon 50mm prime lens has long been a favorite among photographers, and both the 50mm f/1.8D and 50mm f/1.8G versions offer excellent value. But which one is the better choice for your needs? Let’s break down the differences and see how these two lenses compare.

Autofocus – The First Big Difference

If autofocus is important to you, the 50mm f/1.8G is the clear winner. It comes with Nikon’s Silent Wave Motor (SWM), meaning it can autofocus on all Nikon DSLRs, including entry-level models like the D3000 and D5000 series. The autofocus is not only compatible but also quieter and smoother, making it a pleasure to use in a variety of situations.

In contrast, the 50mm f/1.8D requires a camera body with a built-in autofocus motor. If you own a Nikon D750, D7000 series, or higher, this won’t be an issue. However, if you're using an entry-level DSLR, the 1.8D can only focus manually, which might be a dealbreaker if you need quick, reliable autofocus.

Image Quality – A Subtle but Noticeable Difference

Both lenses deliver impressive image quality for their price points, but the 50mm f/1.8G edges ahead. Nikon updated the optical design in the G version, and the results are clear: sharper images, especially when shooting wide open at f/1.8, and better contrast across the frame. Chromatic aberrations, which can be a problem in fast primes, are also handled better in the 1.8G compared to its older sibling.

That said, the 50mm f/1.8D still produces beautifully sharp photos, especially when stopped down to f/2.8 or beyond. But wide open, you might notice a bit more softness and chromatic aberration compared to the G model.

Build Quality – Compact vs. Modern

Both lenses are built well, but there are some key differences. The 50mm f/1.8D is lighter (155g vs. 185g for the G), more compact, and includes a manual aperture ring—a throwback feature that some users, particularly those working with older film cameras, might find useful. Its smaller size also makes it a discreet option for street photography or travel.

On the other hand, the 50mm f/1.8G feels more modern. It ditches the aperture ring for electronic aperture control and adds a weather-sealed mount, making it more resilient in harsh conditions. Although slightly bulkier, it’s still a very manageable lens to carry around all day.

Bokeh – Creamier with the 1.8G

For those who care about bokeh (the quality of out-of-focus areas), the 50mm f/1.8G is the stronger performer. Thanks to its rounded 7-blade diaphragm, the G version produces smoother, creamier bokeh, which is particularly noticeable when shooting portraits or close-ups.

The 50mm f/1.8D still offers decent bokeh, but its 7-blade diaphragm is not rounded, so out-of-focus highlights can appear more hexagonal, giving the bokeh a slightly harsher look in comparison.

Price – Affordability vs. Features

Here’s where the 50mm f/1.8D has an edge: it’s cheaper. If you're on a budget and own a Nikon camera with an autofocus motor, the 1.8D is hard to beat for the price. It’s compact, sharp, and reliable, making it an excellent choice for beginners or those looking for a no-nonsense, affordable prime lens.

However, the 50mm f/1.8G, though slightly more expensive, offers better autofocus, superior optics, and a more refined build. For most users, especially those with newer camera bodies, these improvements are worth the extra cost.

Verdict – Which Lens Wins?

If you’re after a simple, affordable lens and your camera can drive autofocus, the Nikon 50mm f/1.8D is still a great choice. It’s compact, sharp, and a proven workhorse.

But if you have an entry-level Nikon DSLR, or you’re looking for a more future-proof lens with better autofocus and image quality, the Nikon 50mm f/1.8G is the smarter pick. Its combination of modern features, optical improvements, and smooth bokeh make it a versatile lens that can grow with you as a photographer.

In the end, both lenses live up to the "Nifty Fifty" reputation, but the 50mm f/1.8G takes the crown for most users today.
