The difference between cropped and full frame results become oven more obvious. Interestingly, the 35mm F1.4 below at F2.0 still has more blur in the background than the Fuji 23mm F23 at F1.4Īs the focal length increases we see an obvious increase in compression and background blur. As you can see, the blur is noticeably greater with a full frame sensor while the aperture and shooting/lighting settings remain the same. This illustrates the difference in back-ground blur between cropped and full frame. I wouldn’t often use a 35mm equivalent focal length for a studio portrait but it’s a great lens to include more context in an image (as you can see by the various clutter). Fuji 23mm F1.4 Equivalent of 34.5mm F2.1 on full frame compared with Sigma 35mm F1.4 on Canon 5D Mark III If you need a broad depth of field and things more in focus, cropped sensors are a big benefit. If you base your entire style on blurry back-ground photos, full frame sensors are probably your best choice. This is good and bad and depends on your requirements. Simply put, the bigger the sensor, the more blurred the back ground gets at the same aperture, and the easier it is to mis-focus. This means that the smaller the sensor, the broader the depth of field at a given aperture. The crop affects the DOF but not the light gathering ability of the sensor. There are a lot of arguments about focal length equivalents on cropped sensor cameras. Lighting in these comparisons comes from both natural and Cheetah CL-360 lights.

Without even touching the merits of different sized sensors or even the size, weight and cost of the respective lenses, this mini-comparison is designed to simply compare how using different equivalent focal lengths on different systems affects the images themselves (because that’s what really matters!). Full frame sensors vs cropped sensors + lenses Great if you have found a way to make them work for you. Just because you can, doesn’t mean you want to.įor the type of work that I do and they way that I shoot, the Sony system just isn’t ready for ME. Again, this is something I’m not personally interested in. Also, when using adapters for non-native lenses you have to focus manually or you get very slow auto-focus. My Fuji lenses range from 1/2 to 1/3 the size of my Canon lenses. For me this makes no sense at all since one of the biggest reasons for a small camera, is so that everything is smaller. It has been pointed out that you can basically use any lens on the Sony cameras and if you have another system, you don’t have to buy any new lenses. There are a handful of native lenses available but nothing that I’m personally interested in because of the size and cost (example: the FE 28-70mm FF3.5-5.6 is $2000). So one is almost twice the price and the other is more than twice the price. You can indeed get the Sony A7 for as low as $1700 these days, and the A7R for $2300 (the X-E2 is $900). I have had a few comments about the Sony A7 and A7R cameras. While there is one full frame mirrorless system (The Sony A7 and A7R), it currently lacks options for native lenses and costs more than double than the more popular cropped mirrorless models (Olympus OM-D E-M1, and Fuji X-E2 and just announced Fuji X-T1). But what about lenses? How do focal lengths differ between the systems? This isn’t so much a mirrorless vs DSLR debate as much as a cropped vs full frame sensor. For me personally, the portability side of mirrorless systems more than makes up for the downsides. There are always trade offs of course and the mirrorless systems are often more awkward to use quickly and difficult for those with larger hands. The benefits are hard to ignore (See: Comparing the Fuji X-E2 and the Canon 5D Mark III) as mirrorless systems are less expensive and lighter and smaller. A lot of people (as in photographers that I know) have been talking about replacing or augmenting their current DSLR systems with mirrorless systems.
