Crop sensor vs frame lenses1/21/2024 Here’s an example of a shot where I had one thing in mind, but found the DOF at f/1.4 had something else planned. That works for some subjects, but not for all. Suffice it to say that it offers an extremely slim area of focus. I spent this weekend testing my new 85mm F/1.4 lens to see how that shallow DOF worked. Whether that is a good thing or not depends upon your preference and skill. Without getting into technical details, you can achieve a shallower depth of field with a full frame sesnsor than with a crop sensor. ![]() It just didn’t magically provide magnification of my focal length.ĭepth of Field is another factor to consider. It’s clear to me now that I was getting better performance from my lens by using the crop sensor camera that didn’t reveal the vignetting issue. However, don’t dismiss crop sensor bodies as I did. There are benefits to shooting a full frame sensor, such as a greater field of view for composition and better performance at high ISO in low light. Nikon ended up creating a revised version of the 70-200 (which I’ve yet to purchase) to deal with the vignetting problem, and also upgrade the vibration reduction. In other words, it worked better on my DX gear because they effectively cropped out the area of the lens with vignetting and shot through the sharpest part of the lens in the center. What the hell was this vignetting on my photos now? As it turns out, that model of the 70-200 has some pretty heavy vignetting when used on full frame sensors. Finally, I’d be able to use my full frame lens the way it was intended. I bought a D700 and sold every piece of DX (Nikon’s designation for crop-sensor) gear that I owned. One day I decided that I wanted to go completely full frame. When I got my first full frame lens, the Nikon 70-200mm f/2.8 VR lens, I was in heaven. I started off with crop sensors on my Nikon D70 and D200 cameras. That’s a misnomer that’s grown legs, but it misrepresents the truth. In any case, you don’t have additional reach with a crop-sensor camera. However, shoot with your 12 MP crop sensor compared to my 36 MP D800, and I have much more pixel density even after I crop the image to look like the crop-sensor image. Now, that gives you more pixel density of your subject on the final image if both cameras are shooting at the same megapixels per image. On the crop-sensor, the sides are literally cropped off. ![]() Instead, what you see is that there is more width to the frame on the full-frame camera. You aren’t getting any more reach when you use a crop-sensor camera body than if you used a body with a full frame sensor. If you stand in the same spot and look at the same subject using a crop-sensor and a full-frame camera at identical focal lengths, the subject will not appear any farther or closer in either camera. The focal length is the focal length, no matter which sensor you’re using. a crop-sensor camera? Does the crop sensor really give you more reach, or a focal length magnification over the full frame camera body? What’s the difference between a 200mm lens on a full frame camera vs. There’s a belief that focal length magnification helps crop sensor cameras get more “reach” than a full frame camera shooting with the same focal length.
