Full Frame Lens on Cropped Sensor

Full-Frame vs Cropped Frame – What’s the Deal?

I often get asked which lens I recommend……as if there exists a lens that can do it all, for everyone, in all shooting conditions. The fact is, you have to decide what kind of shooting you intend to do, and then figure out which lens can help you, and of course, how much it will cost. In the end, I always recommend either the Canon 50mm prime f/1.8 or the Nikon 50mm f/1.8. They are both full-frame lenses, which simply means the image circle they produce will accommodate a 35mm film frame size, which full-frame DSLR sensors are. Only the higher-end cameras have a full-frame sensor, and virtually no one who asks me about a lens has a FF camera. So why do I still recommend them?


Canon Lens Shootout!

Canon 18-55mm vs Tamron 17-50mm

I wanted a faster lens, so I just bought a brand new Tamron 17-50mm zoom lens to replace the lens that came with my old Canon Rebel XT. When I replaced it with a Canon 40D, I sold the XT body but kept the lens. The Canon kit lens’ maximum aperture is f/3.5, but is variable to f/5.6 at a 55mm focal length. The Tamron has a fixed max ap (stays the same across all focal lengths) of f/2.8. However, I was curious as to what the difference in optical quality was, if any. So I performed my own “Shoot Out!”
