Olympus vs Panasonic 25mm Bokeh & Field of View

Many photographers wonder about the similarities and differences between the Olympus 25mm f/1.8 lens and the Panasonic 25mm f/1.4 lens for the Micro Four Thirds system. I'm also interested to find out.

In today's post, we look at two aspects of the lens, their bokeh and field of view.

The test shots below are shot, at the same settings, using two Panasonic GX7, one with each lens. Tripod is fixed onto a spot while cameras are swapped.

Photos are shot RAW with very minor edits in exposure, and then exported as 2048 wide pixels. You can click on the photos to view the larger 2048 wide size.

My conclusion will appear at the bottom of the post.

Here are the shots compared:

There are some colour differences but we're not going to talk about that.

Vignetting
Panasonic's vignetting is almost gone by f/2.8 while the Olympus still has some traces. But the difference is very minor.

Not sure how many stops darker the images are with the Panasonic but it's a minor issue because exposure and vignetting can be corrected to a certain extent in post.

Bokeh
Both lens render bokeh in a nice creamy manner. That applies when you're shooting small objects up close with a background far behind. Personally, I will not be able to tell which bokeh rendering belongs to which lens.

The differences between bokeh at Panasonic f/1.4 and Olympus f/1.8 is not much of a big deal.

Difference between bokeh is almost negligible if you're shooting subjects at human size. Just look at the photos of the gates. At web size or full resolution, the differences between the bokeh is difficult to discern.

Field of view

This is interesting. The Olympus 25mm has a slightly wider field of view, just slightly so. You get to see a bit more of the scene. Which one is exactly 50mm? Is that important?

Conclusion

If you look on Amazon at the prices of the Panasonic 25mm and the Olympus 25mm, the price difference can be up to $200. Personally, I do not think that the difference in image quality, at least with respect to the bokeh, is enough to justify a $200 difference.

The Olympus lens has the advantage of being smaller and lighter as well. It weighs 136g vs Panasonic's 200g.

Both lens also have the same minimum focusing distance of 0.3m. And the Olympus even has the option to attach a Macro convertor (MCON-P02) to even shorten the minimum focusing distance.

In terms of construction, I would say the Panasonic lens feels a bit more well constructed. Maybe it's the weight that makes it feel more sturdy, or the plastic that feels more premium.

The difference between f/1.4 and f/1.8 is also not an issue when shooting in low light. Noise levels will be close.

In conclusion, Olympus seems to be the lens that's more worth the money.
