Do All Roads Lead To FX
Do you ever look at used camera equipment ads, many now start by saying “selling all my DX gear, moving to FX”. Almost like people are running for their lives to escape a fate worse than death – Having to shoot with DX lenses. The funny thing is most people don’t know why they are going to FX, but it cost more, so it “has” to be better.
Before you sell all your equipment, take the time to know the Pros and Cons of going to a FX body. I have a brief list below that hits some key benefits of each format. It really comes down to the type of photography that you do, and of course the size of your wallet. Digital technology is still emerging, it is not a one size fits all sensor solution yet.
- Smaller cameras and lenses to haul around, size does matter.
- DX lenses are generally less expensive.
- Single zoom lenses can cover a greater focal length range. A big plus when two lenses, a fast 70-200mm and a 17-55mm f2.8 zoom will cover 90% of most shoots.
- You get a free teleconverter, also called a crop factor, which means a 200mm lens gives you the equivalent of a 300mm on a APC DX body, great for sports on big fields.
- You can enlarge a 12 MP DX file just as much as a 12 MP FX file.
- For a given lens and camera to subject distance you get more DOF.
- No more doing crop factor conversions in your head, you get the field of view you expect from a given focal length.
- Wide angle, is really wide angle, and you don’t have to have a super wide angle 12mm lens, because 18mm works just fine.
- You have less depth of filed for a given focal length and subject distance, so the bokeh looks a little better, and you don’t have to shoot at f1.4 to have your subject stand out, you get less DOF.
- More detail in portraits and close ups with the same lens.
- Better high ISO performance due to pixel size, so you have less noise in low light conditions and can leave the flash at home.
