![]() ![]() You are splitting hairs here for the sake of argument. In the title of the post, it says “35mm full frame equivalent” so it’s implied that this is our baseline. In other words, 35mm full-frame equivalent focal lengths will be wider than the quoted focal length for any given GF lens. Since the GFX system has a sensor that is larger than full-frame, we can expect our crop factor to be less than 1. ![]() For example, APS-C cameras typically have a crop factor of 1.5x or 1.6x. Most of us are used to seeing crop factor represented as a number greater than 1. Then you simply divide the diagonal dimension of a full-frame sensor, by the diagonal dimension of the sensor for which you want to find the crop factor. If you know the width and height of a sensor, you can calculate the diagonal dimension using Pythagorean theory. Crop Factor for Fujifilm GFX System CamerasĬrop factor is the ratio of the diagonal dimension of two camera’s sensors. To perform the focal length equivalence conversion, we first need to figure out the crop factor of the GFX sensors compared to a full-frame 35mm sensor. Thankfully, it’s relatively easy to convert the focal length of a Fujifilm GF lens into a 35mm equivalent that is usually easier to visualize if you’re considering a move from a full-frame mirrorless system to the GFX system. This makes it tricky to see focal lengths for the Fujifilm GF lenses and immediately comprehend how wide or tight their field of view is. In other words, a 50mm lens on a full-frame camera will have a completely different field of view to a 50mm lens on the GFX system. With the GFX system using a much larger sensor than that in a full-frame camera, lens focal lengths are not equivalent. Most people are used to seeing lens focal lengths quoted in 35mm terms. Calculating 35mm Equivalent Focal Lengths for Fujifilm GF Lenses By carving out their own unique corner of the market with the GFX system, I’m sure they have a bright future. But Fujifilm has always walked its own path. It’s clear that DSLRs are well on their way to being extinct, and it honestly looks like some companies such as Nikon and Panasonic might have made too many missteps in their transition to a mirrorless world. ![]() Incredibly, after just a few short years from launch, we are at a place where you can get a 100MP medium format camera with image stabilization, for just $6000, and it’s no bigger than a DSLR. After that, we saw the even cheaper GFX 50R rangefinder-style camera, the ground-breaking GFX 100 and then the GFX 100s. While Pentax did pave the way with the 645Z, Fujifilm undercut the price significantly while offering a more modern set of features. Never had there been a more affordable way to get into digital medium format photography. The launch of the original 50MP GFX 50S was something of a revolution in the industry. ![]() What’s more, there are now specialist lenses amongst the lineup, such as the GF 120mm macro and the stunning GF 80mm f/1.7. What was once a limited lens selection has now been filled out with focal lengths from 23mm all the way up to 250mm, with no gaps along the way. The Fujifilm GFX mirrorless medium format system has gone from strength to strength in recent years. ![]()
