Leica SL vs OM System OM-1

Let's look a bit more closely at the Leica SL versus OM System OM-1, both Pro Mirrorless digital cameras by companies Leica and Olympus. The resolution of the SL (24MP) and the OM System OM-1 (20MP) is relatively well matched but the SL (Full frame) and OM System OM-1 (Four Thirds) have totally different sensor dimensions.

The SL was launched 7 years earlier than the OM System OM-1 which is quite a serious gap as far as technology is concerned. Both of these cameras have the same body design (SLR-style mirrorless).

Before diving into a complete comparison, here is a concise highlight of how the SL grades against the OM System OM-1 with respect to portability, imaging, features and an overall mark.

Following is a preview of the gallery photos for Leica SL and OM System OM-1. The complete galleries are available at Leica SL Gallery and OM System OM-1 Gallery.

In case you're looking to travel with your camera regularly, you're going to have to consider its weight and proportions. The Leica SL comes with physical measurements of 147mm x 104mm x 39mm (5.8" x 4.1" x 1.5") having a weight of 847 grams (1.87 lbs) and the OM System OM-1 has measurements of 135mm x 92mm x 73mm (5.3" x 3.6" x 2.9") having a weight of 599 grams (1.32 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will differ depending on the lens you are utilizing at that time. Here is a front view size comparison of the SL vs the OM System OM-1.

Considering dimensions and weight, the portability score of the SL and OM System OM-1 is 67 and 65 respectively.

Sometimes, it is very difficult to see the gap between sensor dimensions merely by looking at specs. The image below will help offer you a stronger sense of the sensor measurements in the SL and OM System OM-1.

As you can plainly see, each of these cameras have different megapixel count and different sensor dimensions. The SL because of its bigger sensor will make getting shallow depth of field less difficult and the Leica SL will give you extra detail utilizing its extra 4MP. Higher resolution will also make it easier to crop photographs a bit more aggressively. The more aged SL is going to be behind when it comes to sensor innovation.
