Fujifilm GFX Crop Factor and GF Lens 35mm Full Frame Equivalent Focal Lengths

The Fujifilm GFX mirrorless medium format system has gone from strength to strength in recent years. What was once a limited lens selection has now been filled out with focal lengths from 23mm up to 500mm, with few gaps along the way. What’s more, there are now specialist lenses in the Fuji GF lens lineup, such as the GF 120mm macro, the GF 30mm f/5.6 Tilt-Shift lens, the GF 500mm f/5.6, and the stunning GF 80mm f/1.7. The launch of the original 50MP GFX 50S was a revolution in the industry. Never had there been a more affordable way to …

What Is Crop Factor, and How Do You Calculate It?

The term crop factor refers to the ratio of a specific sensor to a 35mm full-frame sensor. This factor determines the equivalent field of view of a lens when used on a camera with a sensor that is either smaller or larger than our reference full-frame sensor. Many people are familiar with the two common APS-C crop factors: 1.6x for Canon, and 1.5x for Nikon, Fuji, Sony, etc. But how do we get to this number, and how do you calculate the crop factor for other sensor sizes? Digital Sensor Sizes and Their Crop Factor These are the most common …

Did You Know That Canon Has Three Different Sizes of APS-C Sensor?

I thought I’d write a quick post about this because it caused me some confusion recently while I was creating some resources on calculating field of view and angle of view for camera lenses. The calculations for this require the dimensions of a camera’s sensor, and while working on the data list for Canon lenses I couldn’t figure out why my numbers weren’t quite matching some of those that I had come across on Canon’s own website. A little digging back through archives revealed to me that Canon actually uses three different sizes of APS-C sensor, although I wasn’t able …

Hasselblad X System Crop Factor and XCD Lens Full Frame Equivalent Focal Lengths

Medium-format mirrorless systems are a great way to get into photography with a larger sensor than a full-frame 35mm sensor, so long as you can afford the higher price point. Whilst cameras like those of the Hasselblad X System and the Fujifilm GFX Format are pricey; they are still less expensive than traditional “full-frame medium format” cameras which use even larger sensors. In this post, I’ll show you how to calculate the Hasselblad X System’s crop factor (and reveal the answer) and the 35mm equivalent focal lengths of all Hasselblad XCD lenses, including equivalent f-stop from a depth of field …
